Theories – Origin of Life
September 20, 2008 at 5:35 pm #10139chilipandaParticipant
I’m writing a paper on the origin of life, and I need some suggestions about which theories to write about. Obviously there are tons of them, so any suggestions, information, or references you guys can give me would be great.

Most biologists believe RNA was one of the first biochemical molecules to develop, and experiments have shown that under the right conditions it can perform the functions of itself as well as those of DNA and proteins. In fact there is an entire hypothesis called the "RNA world" that has been developed around these concepts; look it up on google or wikipedia and you’ll find plenty of info.
At my university, a group of students recently conducted experiments in which RNA was found to spontaneously isolate itself inside protective spheres of phospholipids. I’ll have to see if I can get a copy of the research paper; they think this could lead to explaining the formation of the first cells.

basically when you’re writing something like this, you wanna look up what the mainstream belief is and write about that. You may also include a chapter on "alternative hypothesis" but it should be best to stick with the mainstream one

Guyz, has anyone here heard of "Carin Smith’s" theory on the Origin of life?
It tries to prove that the initial replicators was not RNA or some other molecule, but actually "clay replicator".
Check this website dedicated to the theory.
I haven’t read Carin Smiths book but I’ve been reading Richard Dawkins – "The Blind watchmaker" (currently in Ch:8)
I was quite impressed by the theory, it is logical. However I don’t know if there is much evidence for it.
September 25, 2008 at 3:36 pm #86091
It is Cairn-Smith, but if I remember some people that know their chemistry better than I do have been able to point multiple flaw in that otherwise interesting and elegant theory.
September 25, 2008 at 5:40 pm #86096chilipandaParticipant
Carins-smith has two books about the clay theory, "seven clues to the origin of life", and "genetic takeover" i believe. seven clues is very well and easy written, in a sherlock holmes style that is somewhat enjoyable to read. genetic takeover is much more in depth, but has been given very positive reviews. i havent had time to read either myself but i plan on finishing seven clues when i finish my paper.

I think you’d better write about "protein-first and nucleic acid-first" paradox. The research articles of Joyce, Orgel, Eigen and Dyson can be an useful reference for you. Best wishes.

I remember some; Biblical, biogenesis, spontaneous, physico-chemical and cosmozoic theories.quote :
I have thought if they’re viruses but since you have said "phospholipids" my thought lead me to a true cell. It just reminded me of some questions like what made the certain elements to react with one another and form such first biomolecules of life or perhaps their interactions were spontaneous indeed.

I am assuming you mean how it started and the above posts pretty much sum it up but if you mean where it started youve got:
panspermia hypothesis: life came from another planet on meteorite etc.
Bible: you know
or the mainstream – it originated on earth because the early earths atmoshere had no oxygen=no oxydisation=organic compunds are able to exist(e.g. Nucleic acids, proteins, carbs etc) and were created by energy discharges like lightning or using the heat from volcanism.
Google and you will find loads on any of these.
ps. sorry for any typos… im running late for an appointment.

Everyone that has ever commented on the origins of life are reduced to their opinions, even the great Richard Dawkins is left to speculation. The last time I saw Dawkins he said no one knew how the first lifeform started and speculated that it could have come from Aliens. The chances of DNA occuring in nature by accident were put at "No mathematical possibility" That’s 0 for you that have trouble with numbers, The problem with those of us who dont believe in evolution is all the steps it would take to get to advanced life without the species dieing out.All the vital organs that each species have that without any of them "no life". What happened on Earth even 10,000 years ago is really a mystery because there are no written records of those events, of course evolutionists will disregard any other explanation of life as foolish. The Bible says that the proof of God is in Nature, look at the beauty and complexity and then reason.

You should read the first chapter of Nick Lane’s new book "Life Ascending." He discusses the reasons why the "primordial soup" idea is not feasible (mostly because there is very little evidence and there are problems with thermodynamics) and discusses more recent research into life evolving in hydrothermal vents.
December 4, 2010 at 2:14 am #102620
The thing that many seem to forget about the origens of life on earth is that it happened without any competition. It’s not like these molecular oddities had to get started on the current earth. They just had to be able to get the replication/variation/selection cycle started.
DNA doesn’t have to spontaneously generate. RNA seems to be able to start the process of evolution all by itself. Obviously not well by modern standards, but when there’s no competition, no enzymes (RNAases) nothing to get in the way, it’s not hard to imagine that those early RNAs mutated to assemble protiens to protect them, DNA to more stabily store RNA templates and cells to concentrate nutrients.
If you break it down into baby steps it becomes almost inevitable that life happened.

I have a new theory for the Origin of Life on the earth. Life has originated from primordial membranes that have formed from hydrocarbon chains in the earth’s crust about 3.7 billion years ago. These membranes developed electrical potentials resulting in the evolution of consciousness. The erosion of the hydrocarbons by the membrane potentials led to the development of various other organic molecules.
I have propounded a hypothesis with an adequte scientific ground. I have written a book titled "The Role of Cell Membrane in the Origin of Life and in Cell Biology". If you are interested you may discuss it in full detail with me.
December 17, 2010 at 2:14 am #102803
The processes you describe sound like excellent candidates for recreation in the lab. Do you have any simulations in the works? Repeatable evidence is the difference between "science" and "making stuff up".
December 19, 2010 at 10:51 am #102846gabielk1Participant
I thought When Earth was a molten surface. It was Bombarded with space objects that carried the first round of life-bearing substance and imbued the planet with its own sense of identity. Before the earth experiment began and the turning of the hardened planet surface into habitable by electrically shocking the core with a laser, and spray an oxygen shell around atmosphere with plasma ballon inflation. Then people arrived… How come there is no consensus??
December 20, 2010 at 8:32 pm #102868
Pease tell me you are kidding.
March 18, 2011 at 12:52 am #103972
Have any of you thought about the fact that the model of Evolution, is totally destroyed by the Second Law of Thermodynamics, which says that in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state.
March 18, 2011 at 1:45 am #103973
OK I’m going to try to explain the second law of thermodynamics without resorting to math.
The basic idea is that things that are ordered will tend to become disordered. Think of a carefully stacked pyramid of cannon balls. Anything you do to the cannon balls will tend to result in thier no longer being piled up neatly in a pyramid. In fact no matter how much you randomly fiddle with them the chances of them ever being neatly piled in a pyramid again are infinitessimal.
Notice I said randomly. If, however, you decide you want them to be in a neat pyramidal pile and start restacking them you do not violate the second law (obviously it’s possible I’ve seen it done) when you succeed in stacking them. If you only fixate on the pile of cannon balls it appears that the order has increased. The universe, and the laws of thermodynamics,take a more wholistic view. Into the entropy equation go many other things besides the cannon balls small increase in order. There is the energy used by the person doing the stacking (Millions? of molecules of chemicals converted to more random forms, Lots of just plain heat given off by doing Work that cause the molecules in the area to move faster, get farther appart and be less ordered.)
Things can become more ordered locally if the process also makes even more disorder happen elsewhere. Life and evolution are increadably good at this.
March 18, 2011 at 8:18 pm #103989
You said that it appears as if the pyramid, has become more complex, as in an optical illusion, because the really haven’t become more complex, just reorganized, right?
Does that mean that you are saying that evolution just reorganized the cells in animals, so they haven’t evolved, they were just reorganized?
March 19, 2011 at 12:23 am #103995
My explanation was about the 2nd law, not evolution. I said the stacked balls had more order, not complexity. They are not synonymous. You need to understand these concepts without the bias of trying to prove or disprove anything. If you feel you must disprove evolution all you have do do is come up with another theory that explains how life works and is consistent with all the evidence collected by humanity.
March 19, 2011 at 4:12 am #103998
Very true, and that other theory, is called Creation.
March 19, 2011 at 3:47 pm #104002
Many would argue that creationism isn’t even a theory. I think this is wrong. Creationism is a theory and it’s easily stated. God did it. Being scientists we like to check the details though. How, where, why and when did god do it? To be a good beleivable theory you must have good (prefferably logical and obvious) aswers to these questions . Let me also add that evidence can’t be strictly heresay. Because Moses said so doesn’t cut it.
You must also explain my favorite problem with creationism. Why is your intelligent designer so bad at designing? A couple quick examples, The lower back (lumbar vertibrae) , Why do the paths of air being breathed and food being swallowed cross each other? (serious chocking hazard). Why give the gift of flight to birds and not us? Why give a much more efficient repiratory system to birds and not us? Maybe God likes birds better. Ask any doctor for further examples of poor design.
Creationism is a theory, just a bad one that was abandonned in the 19th century for good reasons.
Believe whatever you want but if you choose to believe something stupid I reserve the right to dispute you and laugh at you if it’s really dumb.
March 19, 2011 at 4:54 pm #104003
Also although you may think that Creation has been abandoned, there are thousands of people, that would disgree with you there.
I have said this many times, and I will say it again, if you go back to the very beginning of either viewpoint, you come up with an eternal Intelligent Creator (God) or eternal matter. Evolution takes more faith to beieve in, than Creation.
Also why is it that most people on this website, answer my comments with insults. Sure, I can see that none of you like what I am saying, but throwing insults rather than providing evidence, makes you sound very unintelligent, and not professional at all.
March 19, 2011 at 8:11 pm #104004
I thought we were discussing science not faith. Obviously if you are using faith you can believe anything you want and I can’t argue with faith. Faith does have some spotty history though. Good ideas according to faith, Burning people alive, crashing airliners into office buildings, killing healthcare providers etc. Then there’s the problem of faith in who? You mentioned thousands of people who believe in creation. Can’t argue with that statement but there are hundreds of millions who believe that the creation theory includes the world sitting on the back of a really big turtle. Does that sound more of less silly than flammable shrubbery telling you what to do.
You also haven’t answered my questions about why your intelligent designer doesn’t seem able to design very well. Why creat all those people who believe all those untrue religeons?
As for insulting you, don’t feel bad, Aristotle, one of the great minds of western civilisation, was wrong about everything. It took hundreds of years of science to undo the weird stuff he made up.
Also in science we try not to take things personally.
March 19, 2011 at 11:09 pm #104005
First of all, there is evidence for Creation, as I have shown in many posts on this website.
Second, about why God created people, who do not worship him, God doesn’t want mindless zombies, he wants people to accept him because they feel grateful to him. Think about it, if you were able to create beings capable of their own thoughts, wouldn’t you rather create them, rather than some machine that tells you that you are awesome every morning?
As to the insults I am not merely complaining, I take no offense at your insults, but I like to think that I am conversing with intelligent people, who back up their claims with evidence, rather than people who just call names.
March 20, 2011 at 1:51 am #104013
Still no answer for why the design is so bad and seems to be overly dependent on designs carried forward from earlier ancestral forms. In evolution it’s called evolutionary baggage and it’s just what you would expect.
March 20, 2011 at 2:19 am #104016
Give some examples of bad designs please.
March 20, 2011 at 4:36 am #104032
The chiropractic industry is based on the lower back pain that humans are so prone to.
Only an idiot would have the path of air into the lungs cross the path of food and water into the stomache. Serious choking hazard.
On the subject of breathing our lungs breath in and out through the same path, this mixes new air with old air which is very inefficient. Birds have a better system that uses a series of air sacs to push air through the lung in only one direction.
Heck if I was designing humans I’d make them able to fly and photosynthesize and rationally control our population.
I’d also suggest that sex should be more satisfying with long term committed partners than first time flings and adultery.
Why birth defects?
March 20, 2011 at 1:50 pm #104048
There may be reasons for that setup, as there were for the appendix, which man thought was useless, until it was discovered that it had many purposes. Also there would be many problems, with man being that way, and what do you mean by rationally control our population?
As to your questions, let it suffice to say that if man lived his life the way that God intended him to, we would have none of those problems.
March 20, 2011 at 4:35 pm #104050
When you say "there may be reasons" in science you are then expected to say what those reasons are.
I’m curious, I know what the appendix (Cecum) does in other species. Slow fermentation of fiber.
What are those great things that it does in humans that would outweigh the intense pain and death associated with it? Why can’t God make it work for us without the apendicitis?
In science attempting to avoid answering questions makes people assume you don’t know what you are talking about. Better to say "interesting question, I don’t know". That way people will at least think you gave it some thought.
As you are new to science I will give an example.
God created everything therefore God created cancer. He gave us cancer to make us appreciate life more. Not obviously very convincing to those who get cancer but it at least follows the right form and is logical.

Hypercycles, as an overarching organization of autocatalytic sets, have been proposed as a model for the origin of life (Eigen and Schuster 1977) and are explained at Principia Cybernetica Web. However, complex hypercycles only exist as computer simulations. More than thirty years after the introduction of the hypothesis, there is no experimental evidence whatsoever for complex, possibly prebiotic hypercycles. This makes them still nothing more than mere speculation and, while the hypothesis has been a recurring theme in the scientific literature about the origin of life, it is not frequently mentioned anymore in recent publications in the field.
So far only one, very simple, hypercycle has been generated more than 10 years ago in the laboratory with two self-replicating peptides by the group of Ghadiri (Lee et al. 1997). However, these authors posted a correction (Lee et al. 1998) where they state: “Although the kinetic data suggest the intermediary of higher-order species in the autocatalytic processes, the present system should not be referred to as an example of a minimal hypercycle in the absence of direct experimental evidence for the auto-catalytic cross-coupling between replicators.”
There is a single report on a naturally occurring hypercycle (Eigen et al. 1991). But this example, relating to the infection cycle of an RNA bacteriophage, obviously is not prebiotic – the cycle evolved on the complexity of living beings as template.
March 20, 2011 at 9:10 pm #104065
You might want to use less jargon in this forum because I for one have no idea what you are talking about or why.
March 20, 2011 at 11:33 pm #104071
The appendix helps your immune system. You want me to list the reasons, we haven’t discovered any yet, just like we had no reasons for the appendix, until people understood what it was for. The Bible gives a guideline, on how to live a healthy life, but man completely ignores it, because it mentions cutting out foods that we have grown up loving. There are some groups of people today, who have grown up eating the way that the Bible says to, and those people, are some of the healthiest people on the planet. They do not get cancer or other diseases. The Hallelujah diet, is a diet that focuses on following God’s food laws in the Bible. Cancer patients, given months or less to live, decided to try the diet, (they had nothing to lose) and not only did the live, but they were cured of the cancer, in a relatively short time period. I am not just speaking of a few people either, there have been a few hundred cancer patients cured, and not just cancer patients but tons of people with other diseases too. http://www.hacres.com/library/testimonies/search
Also when did I not answer your question?
March 21, 2011 at 1:13 am #104075
Wouldn’t that be nice if it were true. You see I don’t trust your sources. Lying to forward your biases is just too easy. In science we require evidence that is not tainted by bias. Now when I say lying I am not necessarily saying that intentional untruths are being said. It is at least as likely that the underlying bias has made your sources actually believe what they are saying. Self deception is the easiest because we automatically thrust the source. Science (at least good science) assumes bias exists and goes to great lengths to expose it and compensate for it. Just wanting to believe is a huge bias and requires extreme controls to get to the facts through the fog of bias.
Scientists don’t do multiple controls and double blind studies because we like them. We do them because we don’t trust ourselves any more than we trust creationists.
Murphy is a scientist, whatever can be biased is biased.
April 12, 2011 at 11:18 pm #104418
I have only just joined this forum and have been rather interested in this thread.
In particular the debate between Jonl1408 and BDDVM.
You clearly have a confidence in your bible and trust it considerably. May I suggest that when you debate the bible in a science forum you be prepared to debate science not faith.
Now you clearly believe that the God of the bible designed man (indeed everything else) as the bible states. However the bible also states that something else is at play here in that man’s condition has been tampered with, you have only to refer to Hebrews 2:14 to show that death and suffering was not part of the original design.
Now if someone believes the bible account is just a myth, at least you can point to the account as being consistent within itself and it explains the current situation of man.
What I am suggesting is that if you get to know your bible better you would therefore be better prepared to debate with anyone who does not share your belief.
I can see you are an educated person and adhere to evolutionary theory, although I am uncertain as to what branch of evolutionary theory you subscribe.
However when you state that
“Only an idiot would have the path of air into the lungs cross the path of food and water into the stomache.” I feel you are being more than a little arrogant.
May I suggest you check out the actual design of the human respiratory system and it’s control, perhaps here
http://en.wikibooks.org/wiki/Human_Phys … ory_system and inform how you would modify the system away from idiocy.
Please keep in mind that vague statements about the superior system of the birds is just simple rhetoric unless design detail accompanies your comments.
April 13, 2011 at 12:30 am #104419
Some requested details which I’m afraid will be somewhat longwinded for this forum.
To improve the human respiratory system ( without a major overhaul) simply move the esophagus in front of (anterior to) the trachea so the air pathway and the food/water pathway don’t cross each other.
Avian respiratory anatomy and physiology is kind of complicated but I’ll give it a shot. The windpipe opens at the base of the tongue where debris isn’t trapped easily like the back of our pharynx. A system of air sacs then direct air through the lung in only one direction which keeps incoming air from mixing with outgoing air thus greatly increasing oxygen transfer efficiency. It’s actually a very cool system. If you watch a bird inhale and then exhale the air you see coming out was not the air that was just inhaled, it’s the air that was inhaled the time before. If a bird was smoking the smoke would come out a breath later than expected. If we had this level of oxygen transfer efficiency we could likely run 3 minute miles. I’m just saying that for an intelligent designer the designs look like they were put together without much intelligence.
April 13, 2011 at 1:30 pm #104431quote scottie:
And why would that be? There are countless design that would work better than what we have. Anything that you can imagine where respiratory and food ingestion system are separate. teh point is if it evolved it somehow makes sense for the 2 system to have ended up that way, however absurd and unnecessarily complicated and failure prone it is, but if it had been designed from scratch with even a modicum of intelligence separation of the system would be part of the design requirement.
In fact as with many things there is no need for our body to have all those design quirks that are proving to be annoying (design of our spine, absence of protection of the sensitive abdominal area, excretion and reproduction system sharing conduits…) unless you consider that they evolved from preexisting structures that constrained them so much that a better design was not possible. The problem with (un)intelligent design hypothesis is that it completely fails to explain why if we have been designed, those major problems have not been taken in consideration from the start.
April 14, 2011 at 4:56 pm #104452
Thanks very much for your response. It is certainly educational and appreciated.
I am also glad you have modified the language of your critique in the comparison between the bird/ human respiratory and digestive systems.
I understand the nub of your argument but feel it is a view that is rather simplistic and I don’t mean this in any derogative sense.
In my question to you I deliberately referred to control of the systems, those that which are housed in different parts of the brain. You have simply sought to focus on the mechanics of the systems.
Although there are common functionalities between the two systems the fact is that the human system is far more elaborate and indeed versatile. We have only to examine the taste and vocal abilities of the two to appreciate that one is more sophisticated than the other.
The epiglottis is the flap of cartilage located at the opening to the larynx.
During swallowing, the larynx closes to prevent swallowed material from entering the lungs, the larynx is also pulled upwards to assist this process. Stimulation of the larynx by ingested matter produces a strong cough reflex to protect the lungs.
You rightly refer to choking that occurs when the epiglottis fails to cover the trachea, and food becomes lodged in our windpipe.
The closing of the larynx during swallowing indicates anticipation does it not?
I would argue that this is not a matter of faulty design but one of faulty maintenance.
The two systems operate in two different environments and have different purposes while having some common functions.
I don’t see why should one system be considered the product of idiot design and the other not.
Now canalon raises a good question and I will respond in my next post shortly.
April 14, 2011 at 7:07 pm #104454
I don’t actually believe an idiot designed anything. Evolution did it. The fact that our bodies seem bodgered together is just what you would expect from such a simple and often imprecise process.
Those who advocate the scientific theory of Creationism or Intelligent design must explain why these problems exist (every single one of them). Furthermore their explainations must be consistent with their definition of the creator/ designer.
No fair claiming god created evolution while saying evolution didn’t happen.
Incidentally, part of the nerve supply to the larynx , the recurrent laryngeal nerve, is another example of Rube Goldburg type design.
The nerve starts as a cranial nerve , XI ? I don’t recall exactly. Anyway it starts at he base of the skull and heads south, goes right past the larynx, loops around the base of the heart and ends up at he larnyx. This path makes it one of the longest periferal nerves in the body. Unfortunately periferal nerves have to get all their nutrition and metabolites to the ends of their axons through those axons. This becomes increasingly difficult as those axons get longer. In dogs at least this often leads to the nerve becoming damaged with age to the point that about once a month I see an old dog that can’t open the larynx to inhale. A 50cm nerve that wears out where a much more healthy 10cm nerve would work fine. Not intelligent, evolutionary baggage.
April 14, 2011 at 8:27 pm #104455
When you used the term evolved I assume (correct me if I am wrong) you refer to random variation followed by natural selection i.e. (survival, mate-finding, reproduction)
Now for the moment lets stick with the respiratory/digestive system mentioned as evidence of as you put it (un)intelligent design.
Did you know (perhaps you do) that our mouths can only distinguish 5 different tastes, sweet, salt, sour, bitter and umami (or savouriness).
But you also know that when we enjoy a really good meal we are definitely not limited to those 5 tastes.
So what’s going on?
The other flavours (as distinct from the term taste) is detected by flavour molecules stimulating our olfactory glands in the nose. (part of the respiratory system)
Try the following experiment to see this in action:
Take a piece of any strong flavoured food (say cheese or garlic), hold your nose and put it on your tongue and rub it against the roof of your mouth.
What can you detect? probably just salt or one of the other 4 taste sensations.
Now let your nose go and breath in as you taste (part of the digestive system) the morsel of food, suddenly the flavours erupt in your mouth and nose.
Everything we smell in life comes from these 5 atoms.
These 5 atoms form into different molecules and molecules vibrate at different frequencies and a spectroscope can analyse the vibrations and determine what the molecule is.
We smell molecular vibrations( according to theory), now the fly in the ointment is that if you looked up the nose of the person next to you what you would not see is a spectroscope. 🙂
Birds have an acute sense of taste. Taste is used to help avoid harmful foods. Sensory receptors inside the bird’s mouth detect sweet, salt, sour (acid), and bitter tastes. Sensitivity to each of these tastes differs from species to species.
http://www.seaworld.org/animal-info/inf … senses.htm
The sense of taste is part of their survival package.
Do birds enjoy the full flavour as humans do? The answer is no. One major reason is that the sense of taste and smell do not combine as they do in humans. (separate systems as we are informed)
The point I make is this
This highly developed combination of senses in Humans is clearly not a requirement for survival, findng a mate or reproduction ie Natural Selection.
So the obvious question is why do we posses this quality and not birds.The only good reason I can come up with is pleasure.
Now where does pleasure play a part in natural selection. I don’t know, can anyone educate me please.
To combine the two systems far from being an example of bad design is a excellent example of good design, if only for the reason it adds pleasure to what is otherwise an essential requirement.
I could take up your other points (design of our spine, absence of protection of the sensitive abdominal area, excretion and reproduction system sharing conduits…) but perhaps we could move on to them later
April 14, 2011 at 9:57 pm #104456
I know you don’t believe an idiot designed anything.
But before we go any further I would like to make one thing clear. I am neither a creationist nor an advocate of the ID community.
I have made a study of the various denominations of evolutionary thinking, and there are several, and all coming up with separate ideas.
I have similarly made a study of the bible though not the Qu’ran and the religious churches of Christendom and Islam again come up with different ideas, each one claiming they are right.
Science is my interest.
Science in my opinion should not be tied to any philosophy.
Getting past my bedtime now so must conclude for the time being.
Now I don’t get hung up on terminology. When I see design I see it for what it is –Design. I don’t need to prefix it with adjectives such as “Intelligent” as the ID community does or “Apparent” as Richard Dawkins does.
How did this design come about? Well I don’t see this has been answered by science.
We haven’t even been able to explain what life is so how can science know how it came about. If it came about by supernatural means then science will never be able to answer it.
Science however can explain how it could not have come about.
So when you claim that that it is the result of evolutionary process then I need to pin you down to explain which evolutionary theory you are subscribing to, as there are many.
With respect you have not answered that yet.
Could you possibly answer that question please.
April 14, 2011 at 10:04 pm #104457
Pleasure is evolutions way of rienforcing decisions that make you more likely to live and reproduce. Generally, apples taste good and feces, decayed meat etc taste (and smell) bad. Incidentally there are exceptions as one would expect in a process that takes at least one generation to eliminate deliterious variations. Some people can’t resist feces and other not so healthy dietary choices.
Some of these preferences are learned, some are inate and adjusted by learning and some are inate.
I have been accused of offering simplistic answers to these questions.
In science, simple answers are prefered.
April 15, 2011 at 12:38 am #104458
Scotty I am sorry, I don’t know what you mean by denominations of evolutionary thinking. Could you name a few. Also I’m not sure of your point about the sense of smell/taste in birds. Birds in general have poor sense of both taste and smell. Flight makes smells hard to track and places a premium on eyesight. Food is generally identified visually and is very inflexible. Once a bird starts eating sunflower seeds it’s difficult to get them to even try a food with a different appearence. Even ground sunflower seeds.

My answer is simple: WRONG.
The design is essentially bad and over complicated. The fact that there is a silver lining to that does not make it any better. If the fact that Windows Millenium Edition was so buggy that it required almost monthly reinstall limited the usual accumulation of crap in the registry, it did not make it a better OS than windows 98. 😆
There are countless way to make the 2 systems communicate and do that more safely if you can design it from scratch. Or to have the olfactive system actually located in the mouth (like snakes) or to make the tongue more sensitive. This is a clunky design that was born of randomness and necessity while nature’s tinkering where constrained by the preexisting.
And in fact no amount of rationalisation is convincing: Bad design is bad design whatever later improvment come afterwards. Human have the ribcage of tetrapods, in spite of being bipedals; our larynx and excretion system should not have been connected the way they are if they had been designed. But there never was design or intent, just random tinkering and selection, and a bit of serendipity. Look at the thumb of the panda (and read S.J. Gould’s book by the same name, and most of his other book, they are worth it) and many other examples in nature and all we can see is Chance and necessity (Thank you J. Monod).

Leopol, I don’t know if your post was nonsense before it was translated but it’s certainly nonsense now.
April 16, 2011 at 7:05 pm #104480
Let me try and explain.
(1) There is the modern Standard Theory of Evolution which essentially states .. well
here is a good description from:-
Evolution and the Tree of Life
The modern theory of evolution is based on two primary tenets:
All living things are related to one another to varying degrees through common decent (share common ancestors), have developed from other species, and all life forms have a single common ancestor.
The origin of a new species results from random heritable genetic mutations (changes), some of which are more likely to spread and persist in a gene pool than others. Mutations that result in an advantage to survive and reproduce are more likely to be retained and propagated than mutations that do not result in a survival to reproduce advantage.
The great Tree of Life is real. It is a phylogenetic tree representing the unique ancestral history of each and every creature. Darwin believed that all creatures on Earth might have originated from a single common ancestor so that each species through geological history fit somewhere in an overarching metaphorical tree;
(2) From Wikipedia ( I am always cautious about using wiki but in this case they have it about right.)
Punctuated equilibrium is a theory in evolutionary biology which proposes that most sexually reproducing species will experience little net evolutionary change for most of their geological history, remaining in an extended state called stasis. Punctuated equilibrium also proposes that stasis is broken up by rare and rapid events of branching speciation called cladogenesis. Cladogenesis is the process by which species split into two distinct species, rather than one species gradually transforming into another.
Punctuated equilibrium is commonly contrasted against the theory of phyletic gradualism, which states that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (anagenesis). In this view, evolution is seen as generally smooth and continuous.
In 1972, paleontologists Niles Eldredge and Stephen Jay Gould published a landmark paper developing this theory and called it punctuated equilibria. Their paper built upon Ernst Mayr’s theory of geographic speciation, I. Michael Lerner’s theories of developmental and genetic homeostasis, as well as their own empirical research. Eldredge and Gould proposed that the degree of gradualism commonly attributed to Charles Darwin is virtually nonexistent in the fossil record, and that stasis dominates the history of most fossil species.
Two opposing views on one of the fundamental pillars of of Darwinian theory.
Another fundamental pillar of Darwinian theory is the notion of Common decent. (Tree of life) as explained above.
(3) Carl Woese and others like Craig Venter disagree fundamentally with this concept.
He describes this as “the doctrine of common decent” and is wrong. There is no tree of life, if any such analogy is to be used then a bush or forest would be more appropriate.
Again on one of the fundamental pillars of the standard theory there is disagreement.
So here briefly are three different theories but there are more.
I could relate Jim Shipiro’s Natural Genetic Engineering view which he states is the third way between Creationism and Darwinism.
Or Simon Conway Morris who argues against Gould and Darwin in that evolution far from being quirky and unpredictable is essentially front loaded in that the evolutionary routes are many but the destinations are few.
Or Lynn Margolis... ….I think I had better leave it there in case everyone starts dozing off. 🙂
The reason I use the term denominations is because each theory has it’s own doctrinal fundamentals and the fact that the adherents of one disagree with another, often with a vitriol that smacks of a sort of religious fervour, paints a picture for me.
Does evolution happen? It most certainly does and we have the evidence all around us.
What does that evidence show, well quite simply that all this evolution occurs within species.
Does it produce new species. Well I am waiting for anyone to demonstrate that with evidence and not speculation.
If anyone believes that speciation occurs through evolution by whatever formal theory, I have no problem with that.
It becomes a problem when that belief system is presented a fact.
I hope this clears up some of my points.
btw my comment about birds having a keen sense of taste is actually a quote from the Orlando’s sea world website, I gave the link in my response to canolan, here it is again

Scroll down to Taste.

Well I may be wrong, but you have chosen a rather curious way to try to demonstrate your point.
I assume that of the “countless ways” to make two systems communicate and do it more safely one way would be to take a lesson from the snake ie locate the olfactory system in the mouth and make the tongue more sensitive.
You are aware are you not that the snake requires two senses of smell. One which involves the olfactory system located in the nose (not in the mouth as you have stated) and the other, the vomeronasal system that is associated with the constantly flicking tongue, which incidentally has no taste buds.This system is used in conjunction with the standard sense of smell possibly because the their rate of breathing does not allow the air to enter the nostrils fast enough to collect and translate scent particles in the normal way.
I would suggest that just a cursory examination of the needs of the two (humans and snakes) explains the two different systems and in my subjective opinion as opposed to your subjective opinion there is nothing “clunky” about either system.
However a far more fundamental point is at issue here.
You contend that the human sense of taste and smell evolved from preexisting structures that constrained them so much that a better design was not possible.
This raises two questions which I would appreciate you clarify
(1)From what lineages were these preexisting structures inherited?
(2)Can you provide the evidence for this please.
Finally you are clearly using a designed piece of software to demonstrate how something can’t be designed because of design flaws. Am I right in assuming that this is the logic you are using to support you point, or am I missing a trick somewhere?
I have read Stephen Gould quite extensively, I would be happy to discuss his book(s) later if you wish.

sorry canalon for spelling error
Not sure if posts can be edited for such mistakes
April 17, 2011 at 1:25 am #104487
Where you see differences in doctrinal fundamentals I see differences in detail. The arguements you site are akin to whether ionic or doric collumns are better. They are both collumns.
As for the vitreol and furvor you see in science are simply explained by the fact that humans are involved. Science is not devoid of bias but we make an effort to understand and mitigate those biases.
If you espouse faith as a tool toward fact I would suggest it’s a tool with a very poor record.
After all, If you have enough faith you can believe anything.
As for my current understanding ( I avoid having beliefs, they are too hard to abandon when better evidence is presented) I see the tree of life as being very likely. One or a small handful of projenitors.
Punctuated equalibrium vs gradualism? It depends on the situation(niche).
Some situations cause fast change, some, don’t change and some change gradually.
If you want to get a feel for real time evolutionary change I would suggest you read "The Beak of The Finch" by Jonathan Weiner
about the Grants study of Finches in The Galopagos.
It’s not overly technical so the main theme comes through well.
April 19, 2011 at 11:04 pm #104531
Sorry for the delay but I am a bit tied up on other matters and have not been able to get back to my computer.
I will get back and respond tomorrow just as soon as I am free.
I appreciate this discussion very much because a respectful exchange of ideas and thoughts is always refreshing.
I will try to explain my point of view in order not to be misunderstood.
To me science and faith are two different concepts.
Science is limited to natural laws and any explanation must be confined within the limits of known natural laws.
Now Darwin proposed a theory or model that explained the Origin of Species. Now because it could be tested within the confines of Natural laws it is a valid scientific theory simply because it can be falsified.
He introduced the concept of Natural selection acting on random variation on given species that over time gradually change into another and different species. So this process can be tested and indeed has and continues to be.
If I state that species arrived by an act(s) of a God i.e. by supernatural means then that statement cannot be tested in a scientific way and therefore cannot be regarded as a scientific theory,
That is a belief system that I would be adhering to.
Belief can and often is simply blind and doesn’t require evidence.
Faith on the other hand is something more than belief.
Faith should be based on evidence which maybe directly observed or by strong circumstantial evidence.
In a court for example a person may be convicted of murder although no one actually witnessed the crime but other evidence allows the jury to conclude that the crime was committed by that person.
So faith and belief are in themselves two different concepts although they are very very often used as synonyms.
Now I don’t argue from a point of belief, nor indeed in matters of science do I argue from a point of faith.
What I will try and explain tomorrow is why I argue the way I do, not from a standpoint of belief or faith but from the standpoint of corroborating evidence, because this is a science forum.

I think your definitions of faith and belief might be peculiar to you. In common usage faith refers to beliefs instilled by authority without evidence beyond the word of the authority. As a recovering catholic I can recount first hand the "because God said so" argument. Belief simply refers to ones understanding of reality regardless of how it came about.
To argue another point, I feel that theology is a fine topic for science.
The scientific process is the best tool we have to get to the truth. It isn’t perfect but it’s the best we have come up with yet.
Besides, it was the creationists who claimed that they were scientists.
April 22, 2011 at 12:25 pm #104578
Sorry for the delay but life is a bit hectic at the moment.
The theories of evolution attempt to describe the process by which species arrive.
Now because we are discussing process it is important to understand which process you are subscribing to, as there are various differing theories.
Hence my question as to which theory (process)you subscribe to.
Since you have refrained to address the question I will assume you subscribe to the
first of my descriptions I presented you with, i.e. the Darwinian concept of decent from a single common ancestor. This process of decent being by random mutations within the genetic mechanism and sifted by Natural selection. The whole process operates by the gradual accumulation of changes to produce new species.
(If I am wrong please correct me.)
Let me try and explain my understanding.
The cell is a highly regulated biological information processing system that produces function. By it’s very nature this system is governed by the laws of information theory. Three essential ingredients are required.
A coding system using symbols — the cell has that
A decoding system recognising those symbols —- the cell has that
And a channel for communication— the cell has that.
This system uses the physical laws (physics, chemistry etc) to provide this function.
Now you appear to have indicated that I concentrate on “doctrine” and you on detail.
I am at a loss to understand how you could draw that conclusion, however lets look at some detail of the cell.
In order for a eukaryotic organism to develop and form, cell division takes place.
There are various stages to this cell cycle.
The cell contains several control mechanisms that are referred to as checkpoints and these come into action at various stages of the cycle.
These control mechanisms by their very nature check and verify whether the processes that led up to the particular stage are accurately completed before allowing progression to the next stage.
An important function of many checkpoints is to assess DNA damage.
When damage is found, the checkpoint uses a signal mechanism either to stall the cell cycle until repairs are made or, if repairs cannot be made, to target the cell for destruction via another mechanism.
Now this is but a very small part of the control the cell exercises before it divides, but it is enough to reveal some fundamental points.
(1) DNA damage (which is at the heart of Darwinian theory for speciation) is identified at virtually every stage in cell division and it is either repaired or it is passed on for destruction, except in some special situations. This demonstrates that decisions are being made by the cell, by way of biological algorithms, to eliminate the damage. Damage in the cell is regarded as noise in an information processing system which of course the cell is. Now engineers devote great time and effort to eliminate or at least reduce noise in any system, simply because noise corrupts information. Is it not strange that the very thing that corrupts information is being regarded as one of the fundamental driving forces of evolutional theory, of whatever shade?
(2) Decision points or nodes like this, and there are several in the cell, where the process is directed one way or another cannot come about by chance because natural laws do not work this way. Laws are discovered because endless amounts of dynamic data can be reduced down into mathematical formula, and the reason this can be done is because the behaviour pattern being examined is highly ordered, fixed, and low in information. However degrees of freedom is exactly what is required by the cell systems in living organisms. So not even some yet undiscovered law can address this issue.
(3) This is simply why I recognise design in biology. It has nothing to do with doctrine or belief or faith. It is about science.
Now the argument has been put forward that bad design is evidence of randomness.
However bad design can only be an example of bad design.
Randomness cannot produce the prescriptive design we see in the cell. It is not scientifically possible.
The analogy of the Panda’s Thumb sadly is the perpetuation of this myth.
In 1978 Stephen Gould proposed this as an example of bad design to support his view that bad design is evidence of randomness. However he did not fully understand what he was examining, because he did not have the technology available to examine thoroughly.
Some 20 years later however around 1998 and as technology had greatly advanced, his idea was put to the test and was found wanting.
You will find the paper in Nature (peer reviewed of course) here
http://www.nature.com/nature/journal/v3 … 309a0.html
This is how the abstract reads
“The way in which the giant panda, Ailuropoda melanoleuca, uses the radial sesamoid bone — its ‘pseudo-thumb’ — for grasping makes it one of the most extraordinary manipulation systems in mammalian evolution1, 2, 3, 4, 5. The bone has been reported to function as an active manipulator, enabling the panda to grasp bamboo stems between the bone and the opposing palm2,6, 7, 8. We have used computed tomography, magnetic resonance imaging (MRI) and related techniques to analyse a panda hand. The three-dimensional images we obtained indicate that the radial sesamoid bone cannot move independently of its articulated bones, as has been suggested1, 2, 3, but rather acts as part of a functional unit of manipulation. The radial sesamoid bone and the accessory carpal bone form a double pincer-like apparatus in the medial and lateral sides of the hand, respectively, enabling the panda to manipulate objects with great dexterity. (my emphasis)”
The panda has specific needs (stripping bark off bamboo for some 12 hours a day is not an activity normally associated with other mammals)
This is good design and therefore hardly an icon of bad design.

By the way I am not trying to prove the existence of anything except design.
You should not presume to ascribe motives to me. Don’t demonstrate fear of discussing science by trying to turn it towards some form of religion.
Now how much pop corn do you have?
Why not put it to good use and investigate evidences of Good design in Nature that science learns from.
As the Whale turns
http://www.naturalhistorymag.com/biomec … hale-turns
Read the whole article you will learn something but here is a taster.
“The Humpback Whale….
And underwater, the animals move with such astonishing agility that they’ve caught the attention of naval engineers, who hope that some of the principles learned from the study of the humpback’s flippers can be applied to designing submersible vehicles of unprecedented maneuverability.”
How about Heat exchanger Design
Here is an acknowledgement from by Arthur P Fraas in his book “Heat Exchanger Design”
You will find some extracts here
http://books.google.com/books?id=rdtKXC … &q&f=false
On page 2 he says
“ It is interesting to note that nature presents us with one of the best examples of a highly efficient counterflow system in the blood vessel system in the legs of wading birds such as herons. The warm blood moving outward into the leg from the heart is passed through a system of tiny parallel blood vessels that are interspersed in checkerboard fashion with similar vessels returning from the extremity of the birds leg, giving one of the worlds most effective regenerative heat exchangers. The heat transfer performance of this blood vessel configuration is so good that the warm blood is cooled almost to the ambient temperature before reaching the region immersed in cold water, and thus the bird loses relatively little heat through the skin of it’s leg.”
These are but a couple of examples of design that scientists and engineers look to, when designing their machines. I could go on about the seagull’s wings, the low drag design of the boxfish that the concept car imitates, the shock-absorbing properties of the abalone shells, or the sonar in dolphins etc etc.
So many good ideas have come from nature that researchers have established a database that already catalogs thousands of different biological systems so that scientists can search this database to find natural solutions to their design problems.
The June 9th 2005 edition of the Economist reports .. in part
“This process is entirely the wrong way round, says Dr Vincent. “To be effective, biomimetics should be providing examples of suitable technologies from biology which fulfil the requirements of a particular engineering problem,” he explains. That is why he and his colleagues, with funding from Britain’s Engineering and Physical Sciences Research Council, have spent the past three years building a database of biological tricks which engineers will be able to access to find natural solutions to their design problems. A search of the database with the keyword “propulsion”, for example, produces a range of propulsion mechanisms used by jellyfish, frogs and crustaceans.”
Now if Bad design is evidence of randomness as you argue to then do tell
What is Good design evidence of?
I would say Non-randomness, wouldn’t you or would your theology prevent that conclusion?
Got any pop corn left? 🙂
April 22, 2011 at 7:30 pm #104581
Bad design is not evidence of randomness, it’s evidence of design by a non omnicient, non omnipotent designer.Its evidence of a design process that has limits in how perfect it can be because it has to start with designs that are preexisting.
As for randomness not producing the designs we see in the cell. You seem to forget that only part of the process of evolution is random.
The selection process brutally removes all organisms that don’t fit into an available niche.
An analogy, Obviously it’s impossible for an industrial paint sprayer to paint the greek alphabet in 1” letters on a wall. ( the sprayer paints only a blast of paint 3ft wide) Unless you first mask off all of the wall that isn’t shaped like the greek alphabet. This makes a stencel that removes all the paint that doesn’t fit in the niche. Random paint, non random niche. In life the niche tends to be constantly changeing as well as the organisms that are fit in it.
Variation (Random changes to current design) Selection (non random removal of designs that aren’t fitting) Reproduction. repeat a few quadrillion times.
Now if you walk into a room and see the greek alphabet on the wall in 1 inch letters you can’t say that a random process wasn’t involved.
You might say it appears that someone painted it on with a brush or it might have been done with a stensel. To determine which it was just look closely. A brush will leave brush strokes. The sprayer will show stippled paint and overspray.
We are just saying that the often half baked bodged together designs we see in nature look like paint sprayer evidence not masterful brushstrokes.
(awesome metaphore if I do say so myself)

Sorry for the delay. I have been away for a few days.
I think you have misunderstood me.
It’s not me that is suggesting bad design is evidence of randomness.
This idea has been put out by canalon and you appear to agree with him.
I was merely responding to his assertion. He appears not to answer any questions his assertions raise. So they are coming over as statements of doctrine, and I get very suspicious of doctrinaire pronouncements, because they invariably lack evidence or logic.
When you sayquote :
With respect there is nothing random at all about the cell process. I have explained, and any text book or peer reviewed paper will concur that as a fact.
More than that I have also explained that any mistakes in copying are corrected before cell division takes place.
Random mutations cannot produce the feedback processes we see in the cell. If you say they do then surely it is incumbent on you to show evidence of that.
I am arguing that only design accounts for what we observe in the cell. You keep presuming that I am trying to bring religion into science.
After all my 13 year old grandson studies Design Technology in class and it is not a religious school.
Design is a perfectly valid scientific topic.
Is it your contention that unless the cell arrived by random mutations of the genetic material followed by natural selection, any other explanation must be religiously based.
Could you please clarify your position.
April 28, 2011 at 12:41 am #104679
First all mutations are not repaired, most are repaired, a few kill the cell and an extremely tiny fraction give the cell something it didn’t have before.
It might be your use of the term design that is confusing me. When you say design do you imply a designer that is an entity?
The process of evolution is a design process without an entity guiding it.
This design process has actually been used recently to design robots and some software.
Random processes (Mutation) can result in feedback systems in cells. A well studied system is called the lac operon. It’s a bacterial system for regulating when certain DNA segments are expressed and when they aren’t. Because it is such a simple system it takes less imagination to see how it evolved.
It is not my contention that designer based explainations are religeously based. It is however consistent with all my previous experience.
April 30, 2011 at 4:42 pm #104720quote :
Yes the cell proof reading catches most errors and corrects them. Only rarely, as in such cases as in cancer will a new mutation lead to a phenotype so dramatic that we will realise that something new has happened. Note of course that the new mutation is invariably deleterious. At best these mutations are neutral.
Is there any mutation observed that has resulted in beneficial phenotypic change? If so
Could you please point me to any peer reviewed paper to confirm that.
btw. please think for a moment, do natural laws proof read for errors?quote :
The best way for me to answer that is by referring to the lac operon that you cite
as an example this wayquote :
Firstly to suggest that this is a simple system so that less imagination is required, I find quite astonishing.
May I suggest you review the actual operation of this lac operon. Here is a good visual of what it does and how.
If bacteria encounter two sugars, e.g. glucose and lactose, then E. coli cells will keep the lac operon turned down as long as glucose is present. It is not appropriate if glucose is still available, because E. coli cells metabolize glucose more easily than lactose, it would therefore be wasteful in energy for them to activate the lac operon in the presence of glucose.
This operon is therefore described as a combination of switches, and that is exactly what it is.
Now switches are decision nodes that allow a process to go one way or another depending on what the circumstances require.
There is nothing simple about this system. It requires informational signalling from both within and without the cell. That symbolic signalling determines which switch sequence to turn on or off and when, along with energy saving decisions
We see algorithmic commands such as START, STOP, AND, OR, ELSE and so on
in operation. These things are never seen in natural laws.
We still don’t understand how these genes come to grouped in the way they are on the genome except that this grouping is definitely non random, as a clear understanding of the operon shows.
So this is not haphazard design at work. This is clearly design to cater for different energy sources, functioning with a definite purpose in mind.
It is definitely not a simple system
However by way of comparison lets consider the circular settings of the large upright stones at Stonehenge in England. Some of these massive stones have equally massive cross member stones perched on top.
How did this massive configuration come about?
Does anyone believe that is was the result of natural forces?
And why not ?— after all we have seen for ourselves how in the recent tsunami heavy vehicles being perched on top of buildings in a matter of minutes demonstrating that natural forces do have the capacity to deposit heavy structures on top of others.
But we don’t believe these came about naturally, because we recognise functional design in the configuration. It is simple and it could even be argued that it is not a very good design. Still we attribute it to an outside agency. We don’t know who that outside agency was but yet in the science of archaeology it is carefully studied and accepted that outside agency is definitely involved.
Now can science identify a designer? Well the simple answer is that science cannot.
A historical record can, but that is not a scientific topic.
Also a historical record may or may not be true.
The Churches of Christendom claim that their Triune creator did it.
The Islamic churches claim that their creator did it.
The Hindus claim their creator(s) did it.
The Church of the Flying Spaghetti Monster claims their creator did it, and so on.
These are simply belief systems and therefore cannot be falsifiable in the scientific sense and therefore are not subjects for scientific debate, even though many try to make it so.
However the creator we call decent with modification by random mutations/natural selection claims to be scientific and not a belief system.
Therefore it must be, by it’s very definition, falsifiable.
Please ask yourself this question
Why are there so many different theories about the origin of species i.e. macro evolution?
The answer must be because each theory is simply not fitting the evidence, an essential requirement of any scientific theory.
Just about every facet of evolutionary theory is being falsified time and time again.
This is not a dogmatic statement because the peer-reviewed material is abundant showing this to be so. The interesting point about this material is that most of it is coming from the evolutionary community itself.
I am quite happy to point you to any necessary papers to confirm my argument.
April 30, 2011 at 11:10 pm #104727
First, falsefiable doesn’t mean false. It means a theory that can be tested. If I say, Santa Claus lives at the North Pole. That is falsefiable. You just have to look. Anyone who wants to can look for themselves.
If you say, God just talked to me and told me that I am the new Pope therefore all that cool stuff in the Vatican belongs to me. That isn’t falsefiable. God only talks to me, sorry.
You appear to have a common problem among creationists. A very limited imagination. I have little choice but to assume you are in the creationist mindset as you dodged my question about an entity designer.
The lac operon has only a handful of parts, non of which will mean instant death if it’s missing. Once the bits of the system finally get together in the same E coli it gives a very nice advantage of not wasting recources on lactose metabolic machinery when it’s not needed. It’s just a few mutations. No need to get God involved. Just give the little beasties some time.
I’ve often wondered why God tells his chosen people that they are chosen but neglects to tell everyone else.
April 30, 2011 at 11:30 pm #104728
As for Origen of species. First you have to realise that the concept of species itself is a human construct. There, I said it, I think it’s kind of a red herring. Many will argue with this. That’s fine, It doesn’t mean that we need a God to explain life. It’s another of those detail arguments that some would use to invalidate all of Biology.
As for just about every aspect of evolutionary theory being falsefied, Well to put it cordially, Male Bovid Feces.
If you want to see selection,reproduction, mutation happen in a short period of time. You can do it yourself. Petri dish, bacterial culture, pick an antibiotic, apply it to the plate for a while. What you will see is a large percentage of the initial population die off and are replaced by a new population of bacteria that are more resistant to the antibiotic in question. (unfortunately they will likely also get resistant to several other antibiotics due to how a lot of bacteria share resistance factors).
If you don’t believe this happens I would invite you to take good old fashioned penicillin for your next staph infection.
As you appear to have about the average amount of preexisting bias about this experiments outcome I would suggest you team up with someone who will be able to counter your conscious and unconscious biases with appropriate controls. (scientific method)

Thank you for your two posts
Let me start by responding to the first.quote :
You are actually making my point for me.
For a theory to be considered scientific it must be falsifiable and if evidence is produced to rebut the theory then the theory must be abandoned or at least modified.
However when I present valid scientific arguments that the theory does not and indeed cannot explain, you launch into anti-religious rhetoric. You don’t even know what my belief system is or even if I have one. I have no idea what all this "chosen people" rhetoric is all about
So can we just stick to science please.
You stated that the lac operon is a simple example of evolution.
In fairness you have tried to expand upon that by addingquote :
Firstly, and with great respect, that does not even begin to explain how some pre existing structure whatever it may have been, came to be, what is known as the lac operon.
It’s just a few mutations you say. Is that really the best “scientific” explanation you can come up with?
Simply stating that a few mutations did it is frankly no different the “god did it argument”.
Secondly lac operon is evidence of the system’s built in redundancy that enables E coli to exist on different energy sources.
Redundancy in any system is evidence of forward planning and which is of course evidence of design.
Random mutation by their very nature cannot forward plan.
Another biological fact you need to appreciate is that mutations invariably are deleterious, at best neutral, to the organism. There has been enough experimental evidence over the past at least 60 or so years, to establish that point.
If you wish I will point you some of the research that has been carried out.

How duplication and preservation increases the chances of beneficial mutation while preserving original function (something that would look to the uneducated like "forward planning") –

That took all of 5 minutes searching.

At last someone has decided to engage in some real science.
I was beginning to wonder if the anti-religious flow towards me was ever going to change to genuine science. So once again thanks
Firstly this discussion is in relation to origin of species not the evolution within species which no one that I am aware of disputes.
As I understand it even the creationists recognise this fact.
You claim it took you about 5 minutes to locate these papers, but did it take you 5 minutes to actually read them.
Please point me to any one of them that shows how a new species has emerged.
All these mutations observed did not produce any new species.
Did any of the beneficial mutations produce phenotypic change required for a new species?
I think you already know the answer to that.
Now the latter is particularly interesting, however you have chosen a more dated paper of Lenski.
This paper from 1996 refers to his experiment with E.coli, but what is pertinent is that the paper in it’s opening paragraph refers to the Stephens Gould / Niles Eldridge theory of punctuated equilibriam to explain the origin of species. They developed this theory in response to the fossil record in Cambrian strata that even Darwin himself acknowledged was a real problem for his theory.
Now I would suggest you read his more recent paper(2008) relating to this experiment that was conducted over more than 22 years and involving some 600,000 generations of E.coli growth in 12 population groups.
http://myxo.css.msu.edu/lenski/pdf/2008 … t%20al.pdf
And what appears to be his concluding paper on this experiment (2011)
http://www.microbemagazine.org/images/s … 000030.pdf
In the 2008 paper in his concluding comments he asks the question
“Will the Cit and Cit lineages eventually become distinct species?”
Clearly up to that point the answer was no.
Lets move on to 2011 and his accolade to Darwin
Lets again go to his concluding comments relation to his long experiment to show how Darwin’s theory of the origin Species was being supported by his experoiments.
After all these long years of painstaking experimenting he enters what he terms his midlife crisis.
“From Bacteria to Computers,and Back Again
Perhaps it was a midlife crisis: my bacteria were slowing down, and I was looking for some new action. So I had an affair—one that continues today, though with slightly less feverish intensity—with some artiﬁcial creatures. Avidians are computer programs that copy their own genomes, and they live in a virtual world that exists inside a computer.”
No new species then.
So he has given up on the real world and goes to a virtual reality.
Your third citation
far from showing that random mutations cause new species attempts to demonstrate that these random mutations tend more to immunise species from extinction.. As I read it therefore stasis rather than evolution in the order of the day.
Finally your last citation is simply a hypothesis.
I don’t see how using one hypothesis to support another can be classed as empirical evidence.
I think you will find that things have moved on since 1998
But thanks for your response.

In order to see new species you must do a few things. First define species, relatively easy for sexually reproducing organisms, very difficult for bacteria. Bacteria would be nice because of the relatively short time per generation but the definition problem makes this a non starter.
The best place to look would likely be African rift lake Cichlids. They have been spinning off new species at a very fast rate. Still it’s going to likely take 10’s of years.
Another place to look is in a very small system like Darwins finches in the Galopago islands. "The Beak of The Finch" chronicles the Grants’ herculean multiyear study of these finches separating into 3 species during bad years and hybridizing back into one big genetic blob during high rainfall years. It’s quite readable. They actually captured, measured, and followed every single bird on the Island for many years.
I’m still curious about your version of a designer. Please describe, I can’t argue with your beliefs/biases if you won’t define them. Are you ashamed of your beliefs? Incidentally, I find that saying your biases out load helps to see alternatives more clearly. It seems to help take some of the emotion out.
The reason I don’t site peer revieved papers in this forum is that I agree with Albert Einstien when he said (aproximately) You can’t say you understand a theory until you can explain it to your grandmother.
May 6, 2011 at 10:21 pm #104798
Sorry once again for the delay in responding. I have a very busy life and it does take me away from the forum often for days at a time. I have the weekend ahead so can devote more time to this discussion.quote :
You are right about the need to define species.
Now I can only rely on biologists who provide that definition.
As you say with sexually producing organisms it is fairly well defined.
In the case of bacteria it could perhaps be more subjective.
However I can only take on board what biologists themselves say.
When Richard Lenski who is (was) in the forefront of bacteria investigation in connection with the evolutionary process says quite clearly that no new species had emerged in the course of his investigation, he clearly had a definition in mind.
The E.coli he started with was still E.coli when he concluded.quote :
Now I am familiar with the Grants work.
As far as I am aware all the finches they were studying are sexually reproducing and able to reproduce with each other.
Am I correct?
So,are you saying that finches with different size beaks are now being regarded as different species. Is that correct?
This is how this forum defines speciesquote :
Now according to this definition are all the finches, that the Grants or indeed Darwin himself studied, of the same species or not?
What you are mistakenly doing is noting variation within a given species depending on environmental conditions and promoting it as evidence of one species changing into another.
The finches still remained finches.
Lenski’s E.coli bacteria still remained E.coli bacteria.quote :
Natural Laws can and do produce design. A good example of this is the snowflake.
This site describes nicely how the design in snowflakes is produced.
http://chemistry.about.com/od/molecules … wflake.htm
So one “version of a designer” is Natural Laws and as the site above shows this design can be explained scientifically.
There is another type of design, for example the cell. The Design clearly seen in it’s operation cannot be explained by natural laws alone. Natural laws are in operation but are controlled by what are referred to as biological algorithms.
Algorithms by their very nature are the product of an outside agency.
So the question is, what is that outside agency?
This is a question that science is simply unable to answer because analytical science can only describe natural phenomena.
So I have two “versions of a designer”. One science can describe and the other science cannot describe.
Now regarding the latter a description of this outside agency must naturally be a matter of belief and not science. That belief can be regarded as a religion or philosophy and therefore cannot be analysed by the scientific method.
Let me remind you that this discussion is about a scientific theory(s).
Now I can understand why you appear to want to move this debate on to belief systems because on a scientific basis the argument for species change (origin) by natural phenomena is being lost.
All the arguments you are putting forward are based on a philosophical approach and not as I am arguing, a scientific one.
Some would regard that as a religious approach.
The reality is, you don’t need to know what I believe, to show that what I state is scientifically incorrect. All you have to do is produce the evidence that rebuts my statements.quote :
So please tell, what are you doing making statements you claim are based on science and in a scientific forum if you are not prepared to support them with any recognised scientific evidence. (Although once again you contradict yourself because you refer to the Grant studies of finches)
btw The standard theory i.e. "decent from a common ancestor by random mutation and natural selection" is quite a simple theory and one that my grandson understands. Not sure about my grandmother!
If something is factual you will be able to show it with evidence, if you cannot then it is a belief .
Why not just admit that what you have been arguing is based on a belief system.
That would be a consistent way of presenting your point.

New species created in lab. May 3 issue Proceedings of National Acadamy of Sciences.
I do not agree that Religeous/ Phylosophical beliefs are beyond the reach of science. If it comes out of someones mouth it’s biased BS until the scientific process has been applied. Even then look at it a couple thousand more times.
I can’t disprove or prove your beliefs if you refuse to tell me what they are. Why? are you ashamed? Worried that you might have to rethink your world view?
This is the strongest, most insideous bias there is. Being emotionally invested in your theory.
To test for this bias, simply immagine how you would feel if someone were to prove to you that your beliefs are wrong.
I know , I know, there is no way to disprove the existence of a deity.
But hypothetically, Say a giant intergallactic spaceship arrived and the inhabitants mentioned that they dropped off some bacteria here 3 billion years ago and were just stopping by to see how things were going.
How would you feel?
The most biased statement ever. "I’m not biased, you are."
May 7, 2011 at 4:31 pm #104810quote :
Really now you simply need do better than that.
“New species created in Lab”
Hasn’t the obvious struck you?
An outside agency was required for whatever the result was.
That is precisely the nub of my argument relating to species formation.
Don’t you realise you are making my point for me.
I of course assume you are referring to the “Long-term evolution of Pseudomonas in the human host” article. Even the article does not make the claim you are attributing to it. So please at least report these experiments without any philosophical spin to buttress your arguments.
You keep going on about my beliefs, so let’s put you out of your obvious frustation.
Now you have stated you couldn’t not respond to my enquires because you did not understand theory enough to be able to explain it.
So you don’t really understand what you actually believe.
However I understand exactly what I believe.
I believe in the veracity of the Scientific method.
Here is my understanding of this method and I am very clear about it.
The essential elements of a scientific method are :-
Operation – Some action done to the system being investigated
Observation – What happens when the operation is done to the system
Model – A fact, hypothesis, theory, or the phenomenon itself at a certain moment
Utility Function – A measure of the usefulness of the model to explain, predict, and control.
One of the elements of any scientific utility function is the refutability of the model. Another is its simplicity, on the Principle of Parsimony also known as Occam’s razor.quote :
I assume you include your own mouth in this analysis.quote :
I understand your point completely. Your emotions are coming over in a very obvious manner.quote :
I am still waiting. Please keep trying.
May 8, 2011 at 3:36 pm #104824quote scottie:
Sorry not to have pushed further, but I had to recover from surgery and then had to get back to work. But I will once again try it.
The whole point of the bad design argument is not that bad design is evidence of randomness but that it is evidence of a complete lack of planning, foresight and generally what we call design in nature. See the ancester of bears had a thumb, but they lost it. Then came the Panda and a thumb would have been useful, and instead of taking the old very good design of a thumb, something else had to evolve. But there was no coming back, it had to come from something that was still there in the panda’s genetic toolbox.
The argument is that if there was design, the reliance on necessity and on what is there, instead of what is available in the life’s toolbox in general is proof that there is no overarching design, plan(ner) or anything that can select from what is available at large. And the selection is limited to what is genetically available. That makes sense in the framework of evolutionnary biology, this is stupid if your hypothesize that there is a designer behind things.
And I see that you are using the old Occam’s razor saw a bit down thread. You know the "a designer is a simpler explanation that random accumulation of unlikely event yada yada yada…" kind of argument. Would you care to tell us where the designer comes from? because if there is one, it must come from somewhere, no? And we now have a very interesting recursive loop in the making, that does not appear to be any more probable than random accumulation of rare events followed by selection.
May 8, 2011 at 10:54 pm #104826
Wrong article, It’s the one about the lizards.
It describes a new species of parthenogenic lizards created by hybridizing two related lizards. This is proof of concept for these lizards producing a plethora of related species, both parthenogenic and sexaully reproducing.
Yes I am Biased. I know that and keep it constantly in mind and pay careful attention to how it feels.
Are you claiming a lack of bias?
So you are telling me that the fact that species have never been seen diverging and the fact that species have now been seen diverging are both arguements for intelligent design?
May 9, 2011 at 5:46 pm #104827
I take it then you mean this one
http://arstechnica.com/science/news/201 … he-lab.ars
It describes a new species of parthenogenic lizards created by hybridizing two related lizards.
Here is a clue for you
This article is based on the paper entitled.
“Laboratory synthesis of an independently reproducing vertebrate species.” By Aracely A. Lutes, Diana P. Baumann, William B. Neaves, and Peter Baumann. Proceedings of the National Academy of Sciences, Vol. 108. No. 18, May 3, 2011.
Now I could go into the details of the paper, but the obvious stands out so clearly that I don’t need to dig into it, and here is why.
Hybridization is the cross breeding of related organisms within a given species.
It also involves the input of an outside agency (i.e. the researcher) which is what this research experiment is all about.
Has a new species been created?
Let me refer you back to how this forum defines species.
(1)The lowest taxonomic rank, and the most basic unit or category of biological classification.
(2) An individual belonging to a group of organisms (or the entire group itself) having common characteristics and (usually) are capable of mating with one another.
The sloppy use of this term species can lead to any amount of slight of hand conclusions, if that is where one wishes to go.
Please read the abstract I have provided here
http://www.pnas.org/content/early/2011/ … 8.abstract
Go to the Materials and Methods of the paper to understand the degree of outside input that was required to arrive at their destination
You notice I use the word destination. Why?
Because there was a purpose to this experiment.
Since when has random mutations had a purpose.
Natural selection even, does not come into play.
Artificial selection however does.
You are trying to use artificial input and artificial selection to prove randomness.
What sort of logic is this?
Of course an outside agency can modify the genetic material of an organism to create a different species. (if of course that agency has the capacity.)
That is my point. It requires an outside agency.
I am arguing for design in biology. I don’t need to preface the word with adjectives, be it (un)intelligent, apparent, good bad or whatever.
The biological algorithms we see operating in the cell fit perfectly within the requirements of analysis by the scientific method.
And algorithms by their very nature are not the product of natural law. They use natural laws towards a specific function or purpose.
Now if you can demonstrate any of the evolutionary models to fit into the scientific method of analysis, then you have a genuine scientific theory.
If you cannot then you have, at best a hypothesis that is not standing the test of the scientific method.
Now in fairness you have declared a bias toward this hypothesis of whatever model and
I don’t have a problem with that and do sincerely respect your viewpoint.
All I ask is that you do not present it as science, because then I have to take issue.
Are you claiming a lack of bias?
We all could be guilty of having a bias.
What sticking to the scientific method does in any analysis, is to remove any bias.
Now if you can show me where I have strayed outside the scientific method in any analysis
I have presented I will correct it.
I have no problem in being corrected. I have found through experience, that being corrected is one of the best forms of learning.
May 9, 2011 at 7:03 pm #104828
Your definition of hybrid is wrong. To be a hybrid the parents must be different species. (again we have the species definition to contend with).
and it does happen in nature. The new species isn’t the same as either of the parent species and is self replicating.
If it’s not a new species created by means common in nature, what is it?
Obviously, this is kind of a back door way to create a new species but it is a way that can be accomplished in a short time and is therefore amenable to recreation in the lab.
As I said it’s a proof of concept showing that this group of related lizards could have arisen by simple hybridization.
As for how selection takes place, natural, sexual,domestication, they all work to shape the gene pool. Arguments about which takes precidence I think are silly semantics. Selection is Selection.
Could be guilty of bias? No No No. Always bias, all day every day.
There are still a huge number of people who believe President Obama was not born in Hawaii despite the documentary proof they asked for. As soon as you think you are unbiased then bias has you in it’s insideous grasp.
The hallmark of bias is the inability to take in information that would endanger the comfortable world view that creates the bias. You litterally have to make an effort to see the evidence.
May 9, 2011 at 9:44 pm #104829
Sorry to hear about your surgery, I do hope you are on a good trajectory back to full health.
I understand the argument you are making but it lacks coherence.
Let me explainquote :
You appear to completely ignore any evidence that does not fit your ideas.
The analogy of the “Panda’s thumb” is sheer nonsense and although being refuted is still being perpetuated as evidence of as you now put it of a complete lack of planning, foresight and generally what we call design in nature.
Now really please read the paper if you haven’t taken the trouble already.
You will find the paper in Nature (peer reviewed of course) here
http://www.nature.com/nature/journal/v3 … 309a0.htmlquote :
The panda has specific needs (stripping bark off bamboo for some 12 hours a day is not an activity normally associated with other mammals)
If the panda evolved as you describe ( I will come back to this later) of what better use would the ordinary thumb be over the ‘pseudo-thumb’. Can you explain?
The environment, the diet and the eating habit of the panda required forward planning and foresight as you say and that is what we see.
But it is not just this digit that is evidence of forward planning for particular diet and eating habits.
Here is a description of the digestive system you will find here
http://factsanddetails.com/china.php?it … ubcatid=68
No forward planning eh. It’s all randomness is it?
Now let me come on to this idea of common decent.
You sayquote :
This is just sheer speculation and you know it.
If I were to ask you ( but I wont because you not not be able to give me one) who or what was this ancestor of the bears, you would not be able to give one.
Because there is no evidence for this.
This idea of a common ancestor is based on a Doctrine that has run it’s course and is now being rejected by some of the most prominent biologists.
Among such ones as Carl Woese and many many others there is Eugene Koonin of the National Center for Biotechnology Information, National Library of Medicine, and National Institutes of Health
Koonin is widely regarded and is certainly at the center of the scientific establishment.
In 2007 he presented a paper which is online here
It is entitled
"The Biological Big Bang model for the major transitions in evolution."
May I urge you to read it please and not continue to be taken in by this myth of common decent.
Only the priesthood of Darwinian doctrine continue with this myth.
Now let me respond to your final little bit of rhetoricquote :
Do you accept Kepler’s Laws of motion? – Of course you do
Do you accept Newton’s Laws on gravity — Of course you do
Do you accept Maxwell’s Laws on Electromagnetism – Of course you do
Did Kepler or Newton or Maxwell make those laws? Do tell please — who?
But you accept them all without knowing don’t you?
So instead of all yourquote :
let us make a deal
You tell me who made those Laws and I will tell you who designed the cell.
May 9, 2011 at 10:18 pm #104830
Your point about the adaptation of the panda’s thumb is irrelevant. It does not prove design, just adaptation. Interestingly I would point that the carnivorous and wasteful digestive system of said animal is once again a good argument for its link with other bears (who are all carnivorous). The adaptation of its digestive flora is once again irrelevant to the point, it does adapt. And frigging quickly. Observing variation of any individual digestive flora over time (and even more so if its diet is modified) is easy. Understanding waht happens is another story, though…
As for the laws of physics, nobody designed them. They are the consequence of the interaction whatever constituted the primordial soup of the Big Bang.
But who designed your designer? I do not give a shit who or what it is, but if it has the power to interact with our world, it comes from somewhere. Yet we know that it cannot come from nothing as design is essantial to anything. So who designed your designer?
See that is why it is dangerous to play with a razor, you can hurt yourself.
May 10, 2011 at 1:18 am #104831
I’m still waiting to hear more about this designer. Who, what, when ,where, how?
May 12, 2011 at 12:13 am #104873
Since you are having trouble with a definition of species why don’t you sort out in your own mind what constitutes “a species” and then we can continue our discussion.
Did you really think this one through?quote :
Is this supposed to be an explanation based on science?
Your confusion in the mixing of two concepts from two different hypothesis reveals more about what you don’t understand, than about what you do understand.
The primordial soup is the start point from which Darwin formulated his Origin of species hypothesis. Somehow life came into being from some chemicals.
No one has even figured out what this so called soup consisted of. Scientists have only been able to speculate as to what it may have consisted of.
The most fundamental law in biology is that life comes only from another pre-existing life.
Louis Pasteur clarified this law of Biogenesis about 150 years ago. I take it you did learn about this at school.( Incidently, Pasteur and Darwin were contemporaries.)
Funny that eh ! Darwin hypothesising that life started from a chemical soup and Pasteur showing through science that it couldn’t.
But hey why let science stand in the way of a good story.
The Big Bang hypothesis starts with a mathematical concept called Singularity.
Singularity has no physical existence.
Monsignor Georges Lemaître a Belgian Catholic priest proposed the Big Bang hypothesis.
Of course it had a few rather basic problems so in 1980 Alan Guth bolted on his hypothesis which we know as Inflation theory to try and make some sense of the Big Bang but created even more problems.
By the way George Lemaitre also believed that the Virgin Mary was assumed body and soul into heaven at her death.
Do you now understand the difference between these two theories? Good
So now lets go a little further
Now you should at least know this one.
The most fundamental law in physics is the law of the conservation of energy.
In the natural world neither matter nor energy can be created or destroyed.
Therefore either matter and energy has had no beginning (i.e. it has always existed, the concept of infinity)
it was brought into existence as a consequence of an action outside the physical world.
Since infinity is simply a mathematical construct and has no physical existence the latter must apply.
That is why our Catholic priest thought up this hypothesis to explain how his god would have have created the universe.
So your answer is both scientifically wrong and religiously based.
Your confusion reveals not your science but your religion.
And all religions have dogmas.
So would you like to try again
Once you have absorbed this little lesson we can continue with our science class.
May 12, 2011 at 1:32 am #104874
I’ll make you a deal. I’ll define Species when you define your designer.
I can’t help but wonder why you are reluctant to define your designer.
May 14, 2011 at 3:17 pm #104907
I am able to get back to the forum for the weekend and
Yes I accept your deal
to create, fashion, execute, or construct according to plan or purpose
Examples of designers in the natural world
Birds – constructing a nest
Ants – constructing a anthill
Examples of religion’s chief designers (supposedly)
Christendom’s Triune god
Evolution’s Random mutation
Etc, etc, etc,
Examples of human designers
Isambard Kingdom Brunell — bridges
Isaac Newton — telescope
Robert Oppenheimer — atomic bomb
Etc, etc, etc.
Now Regarding the designer of the cell.
I am not able to define the designer, any more than I can define the maker of the natural laws.
Neither can you or anyone else.
That is why I was able to confidentially offer the deal canalon.
However what I find amusing are the arrogant assumptions some have who claim they can, only to find that when their claims are put to the test and found wanting, they have to try and change the debate to one of belief or religion.
Science does not need to define the designer of anything to acknowledge the fact that design is there.
Religions however by their nature have to, in order to attract believers.
However you can as indeed I can define an understanding of species.
There is enough information around to be able to do this.
So do tell please what is it? I have already given you my understanding.
May 14, 2011 at 4:30 pm #104908
WRONG, If you posit a designer it is incumbant on you to define as much as you can and attempt to prove/ disprove it.
"I believe in a designer that can design the cell." doesn’t cut it.
and they say survival of the fittest is a tautology.
I am only interested in practical theories. Does your designer currently do anything? Will any more designs be forthcoming? Does your designer have any interest in helping or hurting me?
If your designer is beyond the reach of scientific investigation then they might as well be in a different universe and anything said about them is pointless speculation (Phylosophy).
The designer positted by modern biology is well defined. Mostly (if not completely) random changes in the genetic material of preexisting organisms ( or almost living chemical systems capable of some crude form of replication) provide variation in the population. Selection (natural, sexual, domestication) removes variations that don’t fit in an available niche. The remaining organisms reproduce. Repeat, repeat ,repeat.
Things you wouldn’t expect to see. Perfection, this process is a little messy. Completely new designs with no previous history. Virgin birth
Notice I don’t mention your arguement. Complexity is not evidence against this process. Life doesn’t violate any thermodynamic laws.
Organic molecules are perfectly capable of creating bizarrely complex systems without intelligent input.
If you find a watch on the beach it is perfectly logical to look around for the owner/maker. If however you find a crab on the beach there is no reason to look for it’s creator. It’s pretty likely other crabs were involved.

First things firstquote :
If you are going to quote me then do it accurately. Please don’t attribute comments to me I have not made.
This is what I wrote. “Now Regarding the designer of the cell.” And it was in In response to your question
Nowhere will you find that I have said “I believe in a designer”
The only belief I have clearly enumerated is that I believe in the veracity of the scientific method. I also stated my understanding of the scientific method.
It seems very clear now that you are trying very hard to engage in a philosophical debate.
I have repeatedly stated that the cell displays all the evidence of functional design and not the product of random variation.
I have also stated quite clearly that random mutations cannot produce the functional design clearly observed in cell operations and have given scientific reasons why this is so.
Now if the reasons I have provided can be shown to be scientifically inaccurate then please do correct me. If not then my argument stands, because it is based on scientific and not wishful thinking.
You are still evading the issue of species definition so I will give up on getting that from you. 🙂
However you have committed to a definition of thequote :
You statequote :
Now I must presume that you regard this to be a statement of scientific validity.
So let me examine it.quote :
Could you explain what are “almost living chemical systems” ?
Also please describe what you mean by “some crude form of replication”?quote :
This part of your definition is about variation within existing population is it not?quote :
This again is about variation within an existing population is it not?
You appear to be agreeing with me,quote :
This is simple rhetoric that doesn’t seem to make a great deal of sense.
Are you saying that Virgin birth (whatever that is) is spontaneous generation?quote :
Whose is arguing that complexity is evidence of design. Design can be simple or complex and I gave examples in my previous post.
Please address what I am writing and not make up arguments you wish to attack. I think they are called straw man arguments.quote :
Who say’s it does?quote :
Do you not see the obvious contradiction between this statement and your opening statement.quote :
So if the design of crab is as you claim the product of random mutations and natural selection then it is also as you put it
“incumbant on you to define as much as you can and attempt to prove/ disprove it.”
So how does the mechanism of random mutations produce the biological algorithms we observe in the cell?
Now here is an example of such a algorithm.
IF lactose present. AND glucose not present. AND cell can actually synthesize active LacZ and LacY. THEN transcribe lacZYA from lacP ...
You will find an explanation of this here
http://books.google.com/books?id=WSf1FF … 22&f=false
Now if you have any difficulty in understanding how algorithms work don’t worry I will explain it all scientifically.
May 17, 2011 at 12:43 am #104935
Apparently it boils down to the fact that you can’t imagine or can’t allow yourself to imagine that these complex systems, algorhythms if you will, evolved.
I and the rest of the scientific community have no problem imagining this evolution process producing all the life we see, both alive and extinct. There is a reason it’s considered one of the greatest theories ever.
Don’t get too hung up on the species concept, evolution obviously doesn’t.
I apologize for misquoting your apparent arguments about a designer.
You’ve left some significant gaps in your definition which I had to guess at. I was left assuming that you fall into the catagory of creationist/ Intelligent designist. If this is not true I sincerly apologize. If it is true just say so and quit avoiding putting your beliefs out where they can be debated.
May 17, 2011 at 12:55 am #104936
So if I understand your problem with evolution:
– The cell, or living organisms cannot have arisen de novo because nothing comes from nothing
– And self organizing complexity cannot arise spontaneously from chemistry alone
– Ergo There must have been something that designed it.
But you cannot say what that designer might be, or where it comes from, or anything substantial about it. So your Scientific conclusion is that there must be a designer because you cannot imagine anything else, but because you are a scientist you will not say anything about it because that would be philosophy. Great. I am temepted to say that once summarized your argument is a bit crap.

You have summed up your position very well indeed. It is all in your imagination.
I respect you for acknowledging that.
Also you are right about me. I don’t have those imaginative powers. It is a failing I have I must admit.quote :
Now this is a very interesting statement. Am I not correct in understanding that your position is Darwinian based. Is it not also true that his seminal work is entitled “ Origin of Species….”. I have read his work and the term species keeps coming up with almost monotonous regularity. Very strange!!!!quote :
Why are you left assuming?
This is what I wrote on the 14th April.quote :
Now how much clearer do you wish me to be?
I would be happy to sign some kind of affidavit if you wish. 🙂
However apologies accepted.quote :
My belief system is out there to be debated but you don’t appear to want to.
Why are you having such a problem with my belief in the veracity of the scientific method?
I appreciate you don’t have the same faith in it’s veracity as I do, but my faith is very much evidenced based.
That is why I have gone to such great lengths to provide the information from science papers and publications to demonstrate my absolute confidence in my belief.
May 17, 2011 at 9:31 pm #104946
You’re looking through the wrong end of the telescope.
I don’t have any problems with evolution. I know evolution occurs. I also know the limits of what it can accomplish and what it cannot.
With respect you are the one with the problems. You don’t accept the limits that prevent speciation but are unable to support that understanding with evidence.
You still adhere to the idea of common decent and yet molecular biology now demonstrates that this hypothesis has been falsified. I have provided you with the evidence and you take no note. I can do no more than to keep trying to educate.quote :
That is correct, however it does not have to be very complex.
There is a tendency for some to confuse self ordering with self organising.
Self ordering can and does happen. Tornadoes and whirlpools are examples of self ordering, and chaos theory well explains those phenomena.
Self organising however, of which the cell is a prime example cannot be explained by the action of any natural law(s). The origin of the codes operating within the cell can only be speculated at because natural laws do not produce the symbolic information that is clearly evident.quote :
You are right I cannot define the designer of the cell. But then nor can you. You tried to demonstrate how natural laws came about and look at the hopeless tangle you got yourself into.
Come on now be honest, you made a right pigs ear of it didn’t you?
Nothing to be ashamed of though, science can’t answer questions like that, you were just a little bit silly to try.
Religions however supposedly can. All they have to do is construct a dogma and that explains it. Darwinism has become a dogma, no differently.
Now I know this cuts across your belief system, but you are making the claim that you have science on your side.
When I explain and show that you don’t have science on your side, it gets frustrating and shows up in your deteriorating language.
Finally, on this question of naming the designer, May I relate a little sad story from about October 2001.
Three very hardworking guys discovered a quite amazing control system and were put up to receive a prize for all their hard work and ingenuity.
However the prize panel while recognising their tremendous work realised it fell significantly short because they were unable to tell who was the designer of the system. Sadly therefore this system had to be classified as non-designed in the same way as the wheel or the abacus.
However the panel did feel they deserved some recognition so they awarded them a consolation prize.
You will find the whole sad tale here

You miss the point, I do not care if you are a creationist, an IDiot, or simply thick. What i am trying to argue is that the theory of evolution is the only theory that fits and explains life as we see it. If you argue that self organization cannot happen, you have to explain where the organization comes from, what the designer is in other word. It is not a name that I want, but an idea of what the designer is, where it comes from. The point is that your affirmation that self organization is impossible, besides lacking demonstration, throw your reasoning in a recursive loop, and I am curious to know how you get out of it.
But if you provide a reasonned and undestandable model for design, I promise that I will definitely reconsider my views on evolution. Right now however, you seem limited to say that there must be a designer and therefore evolution is wrong. Sorry that does not work. Offer something consistent.
As for your story it is simply irrelevant to the discussion.
May 18, 2011 at 12:32 am #104948
I’m fascinated with this designer. Please can we have some details that we may use to make our daily lives better.
May 20, 2011 at 8:09 pm #104983
That is a very reasonable question so let’s see if I can provide a scientifically satisfying answer.
I will start with an illustration in symbolic representation. Please bear with me.
A person walking past a house notices the roof is on fire. He also is aware that someone is in the house. He has no way of communicating with the householder as he is a deaf mute.
He notices that the front yard is laid with loose pebbles.
He goes into the yard and arranges some of the pebbles of a particular colour to read.
“Roof on fire Get out”
The householder reads the pebbles and escapes.
Now what has gone on here?
The yard pebbles in themselves have no meaning. They are inert, just lumps of pebble molecules.
The passer-by arranged some of the pebbles in such a way as to put a meaning into them. In other words he coded some of the pebbles to convey meaning.
Now the householder had to decode the pebble arrangement. IF he could not understand written English, the message would be meaningless to him. In other words the pebbles would have remained inert to him because he could not decode the pebble arrangement and therefore no function (his escape) would take place.
This is the essence of Shannon communication.
A Coder is required – the passerby
A Channel of communication required – the pebbles
A Decoder is required – the householder.
There is another element that needs to be considered. NOISE.
If for instance the pebble arrangement starts to get messed up due to wind or heavy rain or the householder simply running across it, the arrangement begins to get corrupted. This is noise. Now the coder would have to keep rearranging the pebbles to retain meaning.
The important thing to keep in mind is that the pebbles in themselves carry no meaning. They are inert.
The meaning that is put into the arrangement comes from outside—The passer-by.
He uses a code (written English) and importantly the householder understands that code and can act on it.
Now it is this method of communication that the cell uses.
Here is an example of a fairly simple regulatory system.
The lac operon in E. coli and other bacteria is an example of a simple regulatory circuit. In bacteria, genes with related functions are often located next to each other, controlled by the same regulatory region, and transcribed together; this group of genes is called an operon. The lac operon functions in the metabolism of the sugar lactose, which can be used as an energy source. However, the bacteria prefer to use glucose as an energy source, so if there is glucose present in the environment the bacteria do not want to make the proteins that are encoded by the lac operon. Therefore, transcription of the lac operon is regulated by an elegant circuit in which transcription occurs only if there is lactose but not glucose is present in the environment.
http://ocw.mit.edu/courses/electrical-e … note01.pdf
James Shapiro describes refers to this simple but excellent example of cell coding for function.
"IF lactose present AND glucose not present AND cell can synthesize active LacZ and LacY, THEN transcribe lacZYA from lacP."
The symbols IF AND THEN in this simple functional code have meaning but that meaning in NOT in the molecules themselves.( as in the pebbles) As James Shapiro himself says. They are inert.
http://shapiro.bsd.uchicago.edu/21st_Ce … _Evol.html ( Please spend some time reading it. You will find it very instructive.)
The expression THEN is what is referred to as a Decision Node. These nodes are required in a genetic algorithm for function to take place. Without these decision nodes natural laws take everything forward and is explained very well in chaos theory.
Notice also the expressions IF and AND. These expressions introduce potential into the algorithm. (the algorithm looks forward to note if a particular situation exists and IF it exists then move forward this way). Now when potential is recognised in an algorithm then natural mechanistic laws cannot be involved in that decision making process simply because moving forward takes the course of the algorithm and not natural law.
Now the meaning of these symbols comes from the cell itself.
A good question can be …
How did that meaning come about? But that question does not hinder the science of trying to understand how the cell works. Does it?
If you read David Abel’s and Jack Trevor’s paper “Three subsets of sequence complexity and their relevance to biopolymeric information”
You will find it here
They clearly show that this symbolic meaning cannot arrive in any natural materialistic way and have shown why this is not possible even in theory.
They have put forward 4 Null Hypothesis and invites them to be falsified.
To date there has been no success.
Science only deals with the materialistic world of natural laws.
Shapiro uses the expression Natural genetic engineering because he philosophically wants the answer as to the origin of this process to come from a naturalistic cause. If you removed the adjective Natural from his descriptions of cell functions, the explanatory power of his papers does not diminish in the slightest.
Is there anything wrong with his use of that adjective? Well NO.
It just needs to be recognised what the science is and what the philosophy is.
All too often the boundary between science and philosophy gets very very blurred.
Darwinian evolution that has developed into today’s Modern Synthesis is in reality a Null Hypothesis. This null hypothesis is being falsified by the science of molecular biology.
Random mutations cannot produce symbolic representation. Random mutation is the NOISE that degrades symbolic representation. The cell’s genetic engineering repair systems work at eliminating that noise.
The irony of this is, that noise in an information channel degrades the information content and engineers spend great time and effort in reducing that noise in order to maintain clarity of information. Darwinian theory on the other hand is based on noise being the instrument that drives forward progress.
It totally contradicts Shannon information theory.
Practically every molecular biologist around the world is discovering what James Shapiro is so ably presenting, in showing that the Darwinian process is simply not the mechanism that explains speciation. That mechanism is simply not known.
In my next post in a couple of hours I will try and provide another example that visually is more instructive.
May 20, 2011 at 9:02 pm #104984
And will you make any progress toward answering the question?
"If design cannot be spontaneous, where/how did the designer originate?"
May 20, 2011 at 9:30 pm #104986
Let’s take another example but this time with far more selective power. I will try to make it more visually descriptive to demonstrate the process.
DNA molecule carries the instructions which are absolutely necessary to produce enzymes, different nucleotide complexes, and smaller protein molecules used in the processes of transcription and translation. One of such important tools are tRNA molecules. Each living cell constantly utilizes some 40 different forms of the tRNA molecule.
We will look at the yeast DNA gene for tRNA tyr
The tRNATyr gene has to be found in one of the chromosomes. Here that gene is represented with the aid of the four symbols A, C, G, T, substituted for the rather complex chemical formulas of four the different deoxyribonucleotides:
Here it is.
GTTATCAGTTAATTGACTCTCGGTAGCCAAGTTGGTTTAAGGCGCAAGACT GTAATTTACCACTACGAAATCTTTGAGATCGGGCGTTCGACTCGCCCCCG GGAGATT
Don’t worry about the exact meaning of this sequence just note the configuration changes as they come along.
The DNA gene has to be copied (transcribed). The gene remains intact in the structure of the given chromosome. The subunits of the copy are made from a different kind of sugar (not deoxyribose, but ribose), and one of the original organic bases (T) is substituted by another one (U):
So the early RNA transcript of the gene is
GUUAUCAGUUAAUUGACUCUCGGUAGCCAAGUUGGUUUAAGGCGC AAGACUGUAAUUUACCACUACGAAAUCUUUGAGAUCGGGCGUUCG ACUCGCCCCCGGGAGAUU (notice the T’s are now U’s)
Both the tRNATyr gene and its faithful RNA copy consist of four different units linked in a sequence 104 subunits long. Now this may seem to us quite random, but in fact it is absolutely non-random, i.e. this specific sequence is closely correlated with the final, functional properties of the tRNATyr molecule. Virtually any change in this sequence makes it unfit to fill properly its job in the cell.
This non-randomness is usually called selectivity.
This RNA copy dictated by the structure of the tRNATyr gene undergoes many further complex modifications before it changes into the functional primary or mature structure of the tRNATyr molecule.
Parts of the precursor 1 copy have to be removed. The removed elements are written in lowercase red
guuaucaguuaauugaCUCUCGGUAGCCAAGUUGGUUUAAGGCGCAAGA CUGUAAuuuaccacuacgaaAUCUUUGAGAUCGGGCGUUCGACUCGCCC CCGGGAGAuu
Which give us Precursor 2
Several single units have to undergo a transformation. The transformed elements are the final, functional primary structure of the yeast tRNA Tyr
Have a look again at the early RNA transcript of the tRNA gene dictated by the sequence of the DNA gene the early RNA transcript of the gene – the supposedly unique source of information
GUUAUCAGUUAAUUGACUCUCGGUAGCCAAGUUGGUUUAAGGCGC AAGACUGUAAUUUACCACUACGAAAUCUUUGAGAUCGGGCGUUCG ACUCGCCCCCGGGAGAUU
The final, functional primary structure of the yeast tRNATyr differs considerably from the original DNA gene.
It is shorter than the gene – just 78 subunits long, but it is composed not from four but from eleven different subunits.
The original DNA gene is simply a very rough and incomplete information set that is required to produce the function it is required to. It has to be modified
The process of modifying the raw precursor involves a considerable increase in the selectivity of the product. This increase is over 1000 fold.
In other words the selectivity guaranteed by the DNA gene is insignificantly small in comparison with the selectivity really needed and actually somehow provided.
So where does this enormous selective power reside? We don’t know.
About 14 years ago mRNA editing was discovered. This means that the DNA genes, in some cases, do not determine the proper sequence of amino acids. The information provided by DNA messages is – in these cases -simply wrong, from the functional, biological point of view, and it has to be edited during a separate stage. As a result of this editing the original, primary molecular meaning of a given gene can be radically changed.
If DNA is the main ruling agency of the body mechanisms, then any mutilation of the DNA molecule should be fatal and unrecoverable. In reality DNA can, and is constantly being repaired. Somehow the organism knows how to detect a change in the genetic message, and utilizes many different, complex procedures to repair different forms of mutation.
Here is another spanner in the works of the one gene one function concept
http://www.sciencemag.org/cgi/content/a … +One+Codon,
As the abstract concludes
“Thus, the genetic code supports the use of one codon to code for multiple aminoacids.”
In linguists we have homonyms, one word having two meanings. The meaning is determined by the context. ( bear –an animal but also to carry something) the context determines the meaning.)
So here we have the cell displaying a quasi-linguistic capability.
How did that meaning come about? Also where does that algorithm reside.
The simple answer is we do not know.
The present, almost completed inventory of the cell certainly does not contain any complex set of structures that we can identify with this type decision making code (and there are countless numbers of this information storage)
In a computer for instance we find these algorithms written onto the hard drive. But with the cell we have no idea as yet where these algorithms reside.
What is clear though is that symbolic information that is so clearly evident has to come from somewhere. It does not reside in the chemical nature of the molecules.
Random mutilation of DNA for example does not provide the prescriptive information that we see in cell operation.
In communication theory mutilation of any data is regarded as noise. And noise corrupts the signal. That is why such care is taken to eliminate noise from a communication channel..
So what we are seeing in these two examples are features of operations we would expect in genetic engineering design. As James Shipiro describes it Natural Genetic Engineering.
Please reflect on his concluding submission entitled
A 21st Century View of Evolution.
In part he states
The last half century has taught us an astonishing amount about how living organisms function at the molecular level, in particular about how they execute cellular computations through molecular interactions and about the systemic, modular, computation-ready organization of the genome. We have come to realize some of the basic design features that govern genome structure. Combining this knowledge with our understanding of how natural genetic engineering operates, it is possible to formulate the outlines of a new 21st Century vision of evolutionary engineering that postulates a more regular principle-based process of change than the gradual random walk of 19th and 20th Century theories. Such a new vision is not all-encompassing because it cannot provide detailed accounts for major events currently beyond the reach of science, such as the origin of cellular life or the mechanisms of endosymbiotic events underlying the emergence of distinct superkingdoms and kingdoms of life (51, 52). Nonetheless, a 21st Century view of evolution can help us understand how new taxonomic groups have emerged bearing novel complex adaptations.
May 20, 2011 at 11:56 pm #104988
And your point is…..
May 23, 2011 at 8:28 pm #105010
This question is very confusing.
Where have I stated that design cannot be spontaneous?
May I remind what your original question was.quote :
This is what I am in the progress of dealing with. So I will continue.
Now I deliberately waited a while before continuing in the hope that you would read the papers I have cited.
IF you have then you will know the answer to the question raised. However for the sake of clarity in case you have not fully absorbed the information I have presented.
Allow me to quote directly from his (Shapiro’s)paper that incidentally has referenced some 56 other papers and articles in support of his presentation.
Here is the paper again
http://shapiro.bsd.uchicago.edu/21st_Ce … _Evol.html
Under the heading
A 21ST CENTURY VIEW OF EVOLUTION
"The last half century has taught us an astonishing amount about how living organisms function at the molecular level, in particular about how they execute cellular computations through molecular interactions and about the systemic, modular, computation-ready organization of the genome. We have come to realize some of the basic design features that govern genome structure.
Combining this knowledge with our understanding of how natural genetic engineering operates, it is possible to formulate the outlines of a new 21st Century vision of evolutionary engineering that postulates a more regular principle-based process of change than the gradual random walk of 19th and 20th Century theories.
Such a new vision is not all-encompassing because it cannot provide detailed accounts for major events currently beyond the reach of science, such as the origin of cellular life or the mechanisms of endosymbiotic events underlying the emergence of distinct superkingdoms and kingdoms of life (51, 52).
Nonetheless, a 21st Century view of evolution can help us understand how new taxonomic groups have emerged bearing novel complex adaptations."
He then summarises in the following way
"� Major evolutionary change to the genome occurs by the amplification and rearrangement of pre-existing modules. Old genomic systems are disassembled and new genomic systems are assembled by natural genetic engineering functions that operate via non-random molecular processes.
� Major alterations in the content and distribution of repetitive DNA elements results in a reformatting of the genome to function in novel ways –without major alterations of protein coding sequences. These reformattings would be particularly important in adaptive radiations within taxonomic groups that use the same basic materials to make a wide variety of morphologically distinct species (e.g. birds and mammals).
� Large-scale genome-wide reorganizations occur rapidly (potentially within a single generation) following activation of natural genetic engineering systems in response to a major evolutionary challenge. The cellular regulation of natural genetic engineering automatically imposes a punctuated tempo on the process of evolutionary change.
� Targeting of natural genetic engineering processes by cellular control networks to particular regions of the genome enhances the probability of generating useful new multi-locus systems. (Exactly how far the computational capacity of cells can influence complex genome rearrangements needs to be investigated. This area also holds promise for powerful new biotechnologies.)
� Natural selection following genome reorganization eliminates the misfits whose new genetic structures are non-functional. In this sense, natural selection plays an essentially negative role, as postulated by many early thinkers about evolution (e.g. 53). Once organisms with functional new genomes appear, however, natural selection may play a positive role in fine-tuning novel genetic systems by the kind of micro-evolutionary processes currently studied in the laboratory."
He concludes this way
"Molecular genetics has amply confirmed McClintock�s discovery that living organisms actively reorganize their genomes (5). It has also supported her view that the genome can "sense danger" and respond accordingly (56).
The recognition of the fundamentally biological nature of genetic change and of cellular potentials for information processing frees our thinking about evolution. In particular, our conceptual formulations are no longer dependent on the operation of stochastic processes. Thus, we can now envision a role for computational inputs and adaptive feedbacks into the evolution of life as a complex system. Indeed, it is possible that we will eventually see such information-processing capabilities as essential to life itself."
In 2009 Shapiro revisited this subject and you will find his paper here.
http://shapiro.bsd.uchicago.edu/Shapiro … 0Dogma.pdf
This time citing 154 reference articles.
“Natural Genetic Engineering
Underlying the central dogma and conventional views of genome evolution was the ideathat the genome is a stable structure thatchanges rarely and accidentally by chemicalﬂuctuations or replication errors. This view has had to change with the realization that maintenance of genome stability is an active cellular function and the discovery of numerous dedicated biochemical systems for restructuring DNA molecules.
Genetic changeis almost always the result of cellular action on the genome. These natural processes are analogous to human genetic engineering, and their
activity in genome evolution has been extensively documented.”
In summary therefore
The mechanism for genetic change is the natural genetic engineering process Shapiro describes.
Old genomic systems are disassembled and new genomic systems are assembled by natural genetic engineering functions that operate via non-random molecular processes.
Basic design features are now recognised
Major change occurs suddenly (potentially within one generation and supported by the fossil record)
You will notice that although Shapiro acknowledges the design engineering process. He also states that it’s origin is currently beyond the scope of science.
If you want to persist in your argument of having to name or describe a designer, for the process to be credible, then your argument against the evolutionary community itself.
Because Shapiro is an evolutionary biologist and so are a great number of scientists who also recognise this process.
There are a reducing number of biologists who still subscribe to the Darwinian process of random mutations.
The main protagonists are notably Dawkins and Coyne who seem more interested in promoting their religious views rather than science.
May 24, 2011 at 2:44 am #105011
So, if not random mutations, what? Do you suggest corn is consciously redisigning itself ? To me it just looks like another aspect of the Red Queen. (Keep the rate of change in your genome at least as high as your parasites or be replaced by someone who does.)
May 26, 2011 at 10:29 pm #105049
Scottie, if there is design, there is intent or a designer.
You have been arguing that randomness cannot explain the complicated funcctions that are observed in every life form, and that as consequence life has to be designed.
So once again:
who/what is the designer of life, and where did it itself come from.
I am not interested in the rest. you are dodging the essential question and your longwinded evasions are tiring.
May 27, 2011 at 12:12 am #105055
Come on Scottie at least give us a hint about the designer. The suspense is killing me. Or are you just trying to manufacture some "controversy among the scientific community".
May 27, 2011 at 5:02 pm #105067
Well you have lost the argument on science and so you are reduced to sarcasm.
OK so that is your method of debate. I’ll run with you then.quote :
Now despite all the evidence, are you really still running with random mutations? 🙂
Oh dear I was hoping your claim to be a person of science had some merit.
You might just as well swap “random mutations” with “The Flying Spaghetti Monster” . 🙂
No no you have it wrong.
I havn’t been arguing that randomness cannot explain..
I have been proving it.quote :
I take it then you are not interested in the evidence that science provides.
My “long winded evasions “ as you put it are the product of actual empirical evidence provided by peer-reviewed papers from the scientific (evolutionary) community and what is more you have not provided a single refutation.
Come on admit it, you know you have lost the scientific argument so your only avenue of escape now is to change the subject to your religion. But as I have said before I don’t do religion.
I know it hurts to be shown up on actual science, especially when so much emotional energy has been invested in a belief that is coming apart at the seams.
The Pope has the same problem you know, so don’t feel too isolated, you are in good company.:)
Look isn’t it better to acknowledge you are wrong than to religiously stick to a dogma that simply does not stack up.
Science progresses through the falsification of previously held views or hypotheses.
In fact it is this kind of falsification that elevates true science from a lot of the claptrap that so pervades life.
May 28, 2011 at 2:42 am #105071
Still no hints about the nature of the designer?
How can your theory be falsified if you refuse to give any details?
Some direct questions about your designer.
Currently designing? or Finished designing a long time ago?
Does the designer have any interest in my well being?
None of these questions should take more than a few words to answer.(this forum doesn’t work well with long arguements.)
May 28, 2011 at 3:47 pm #105074
Here is a short reply
Do you wish to discuss science or religion.
Because my understanding is that this is a science forum?
May 28, 2011 at 6:33 pm #105075
scottie: you came up with the designer, so don’t ask whether to discuss science or religion and answer the questions.
May 28, 2011 at 7:03 pm #105076
Let ‘s try and understand what science can or cannot do.
This is really primary school stuff and I genuinely thought I was in discussion with an intellect beyond this level, but apparently not.
So let’s take for example my Honda Accord vehicle.
Science can determine that it has been designed by someone and manufactured by someone, because firstly it has function, also because it has parts that have the attributes of manufacture. It has circuitry and a computer system that has feedback loops etc. It has heat exchange systems that again have the attributes of design etc etc etc.
That is what science can tell you. Actually it is pretty much a matter of common sense is it not.
However science cannot tell you who designed or manufactured it.
That information can only come from some form of historical record.
What is so difficult to understand?
This is something an eight year old child can understand.
Now the cell has all the attributes of design. That is not in question.
Any biologist will affirm that.
The question is not whether it is designed.
The question is whether that design can come about by random mutations.
The theory of random mutations claims to be a scientific theory, therefore it can be examined by the scientific method to determine whether that can be so.
Now I have at very great lengths presented the evidence from within the scientific community to demonstrate that random mutations cannot produce the attributes of function we observe in the cell.
You have not been able to scientifically refute any of my posts.
Now many of the religions of this world claim to know how this came about.
However they cannot demonstrate it through the scientific method, therefore they rest their case on a belief system and those beliefs are founded on Dogmas which adherents hold dear.
That much is clear is it not.
The problem you have is that you also have a Dogma which is random mutations, but the difference is that you claim it to be scientifically based.
That is where your problem is, because when the scientific method is applied to this Dogma it fails the test.
Now no end of sarcasm and cat calls will alter this very simple fact.
If you say that this is what you believe, then that is a very different matter, simply because a belief system, or philosophy or religion takes this matter beyond science.
What I have done is not present a theory of design.
I have presented facts that demonstrate the cell is designed.
Now who or what designed it is beyond the reach of science.
To determine who or what designed it must be a matter of an historical record and not a scientific record.
May 28, 2011 at 8:11 pm #105077
I simply don’t aggree that your designer is beyond the reach of science.
Therefore I am requesting some information about your designer.
I’m afraid "I don’t believe in your theory and I won’t tell you mine." sounds a little juvenile.
May 28, 2011 at 8:24 pm #105078quote scottie:
Actually, that has no attributes of design, but attributes of creation, but doesn’t tell you anything what has created it. Whether it was someone or the previous generation of Hondas.
May 30, 2011 at 1:51 pm #105089
I really don’t understand why you are having such difficulty in recognising the obvious
Darwin introduced historicity into science. Evolutionary biology, in contrast with physics and chemistry, is a historical science – the evolutionist attempts to explain events and processes that have already taken place. Laws and experiments are inappropriate techniques for the explication of such events and processes. Instead one constructs a historical narrative, consisting of a tentative reconstruction of the particular scenario that led to the events one is trying to explain.
The discovery of natural selection, by Darwin and Alfred Russel Wallace, must itself be counted as an extraordinary philosophical advance.
All you have to do is recognise that natural selection is a philosophical concept. No different from the philosophical concepts of other religions.
What is the problem?
May 30, 2011 at 1:53 pm #105090
probably recognizing, that it’s only philosophy, since you can have experiments to confirm or not the evolution. Even more, you can see it in the nature.
May 30, 2011 at 2:08 pm #105091
What I wrote (the above)in my last post is a direct quote from Ernst Mayr himself in his lecture of 1999
You will find that lecture here
http://www.biologie.uni-hamburg.de/b-on … luence.htm
One of the founding fathers of the modern synthesis proudly hails Darwinism as a philosophy.
You are now taking on Ernst Mayr, well good for you.
May 30, 2011 at 2:42 pm #105092
that’s nice example, how context may change meaning.
May 30, 2011 at 3:12 pm #105093
Phylosophy is the intellectual persuit of truth. Science is a rather recent and far more effective tool than the biased hand waving(and coersion) of the past. Scottie, stop the evasions,long winded obfuscations and name dropping. Just explain your theory.
May 30, 2011 at 3:21 pm #105094
The context has not changed any meaning.
Here is what he went on further to say in the same lecturequote :
No context change here at all.
Ernst Mayr was simply being honest and indeed proud of it.
Evolutionary theory is not a physical science it is a philosophy that is being promoted as a physical science.

You postedquote :
Ok let’s put that statement to the test
Craig Venter and his team made headlines when they announced their success in transforming and existing cell into a cell with as he put it “with no biological anscester”
He published an account of what his team accomplished in the Science Express portion of the journal Science. Here is an excerpt from the 12-page report.quote :
They made this long DNA molecule by putting together smaller segments of commercially available DNA which they purchased from Blue Heron. They purchased pieces that were about 1,000 base pairs long and joined ten of them together to form pieces that were about 10,000 base pairs long. They took ten of these 10,000 base pair pieces and joined them together to form pieces about 100,000 base pairs long. Finally, they joined eleven of these 100,000 base pair pieces together to form the complete molecule.
In other words they designed and built a new genome and inserted this genome into the cell of another bacterium and it booted up.
As he saysquote :
Now take any number of biologists and examine that cell. Make sure they have no information about how that cell came about. We know that it was clearly designed and built(or at least an important part of it was).
Now just for clarity here is your statement againquote :
So please explain to me but more importantly to this forum, how these biologists by only using the tools of science can determine who the designer and creator of this new species is.
If science can do that, then you should have no problem demonstrating it.
Please prove me wrong.

Sounds like Craig Venter was the designer in this case. I’m pretty sure you can’t extrapolate that very far. Craig Ventor is human, he was engaged in a scientific exploration, and I doubt that he has created any other life. (Being a scientist he wouldn’t keep it a secret.)
Now back to your designer. WHO? WHAT? WHEN? WHERE? hell I am even curious about WHY? Inquiring minds want to know.
By the way, if your apponant in an arguement gets tired, annoyed,exasperated and decides argueing with you is pointless, it doesn’t mean you have won the arguement. This is a common misconception among crackpots. Crackpots believe that when people politely nod and smile that they are aggreeing with the ranting. It just means that they know a crackpot when they see one and know that it can be dangerous to provoke the delusional. Don’t be a crackpot.
May 30, 2011 at 10:54 pm #105101quote :
No NO it doesn’t sound like Craig Venter. It was Craig Venter and his team.
And how do we know that Venter is the designer?
Because he has provided an historical record, or has that simple point escaped your notice.
Without that record we would not know who created it.
We would not know by examining the cell itself with all the science at our disposal.
As I have said before and repeatedly, neither I nor any other person could tell who created the cell without some form of authentic historical record, any more than could you tell who designed and made this cell without an historical record to accompany it.
Surely even you with all your intelligence can understand that, can’t you?
As for me, well I am just a crackpot aren’t I, so how could I possibly explain such simple concepts to you. 🙂
May 31, 2011 at 12:20 am #105102
I’m having trouble seeing what this experiment says about your designer.
I recall you were at one time hung up on the idea that creating a new species was not possible. Even though it’s just a bacteria it is a new species, lab created. Just like the lizards.Two proofs of concept.
It seems your designer hasn’t been doing anything metaphysical, just physical and well within the pervue of science.
Sooooooo, once more Please describe your theoretical designer.
If you evade this question once more I will give up on you and you will no doubt conclude (incorrectly) that you have won this arguement.
May 31, 2011 at 2:07 pm #105111
Well there you go, rambling again. (bad sign) 🙂
However let’s try and unravel your confusion.quote :
You really must not rely on your powers of recall, a very uncertain process. Go and read my posts again. It really isn’t that difficult, it is in English.quote :
It does seem that you have some difficulty with language. I need to take that into account in future. Very remiss of me, please accept my apologies.
Where have I stated or even relied on anything metaphysical?
In fact I have been arguing that the metaphysical is within your argumentation and therefore not physical science.quote :
Oh come come, I don’t need to conclude anything. You reveal it all for yourself far better than I could ever conclude.
I will of course try and educate if you wish to continue. Patience is a virtue I have tried to develop over many years now, so don’t worry you won’t be in any danger of trying my patience, honest. 🙂
June 1, 2011 at 12:18 am #105121quote scottie:
Please back up this absurd statement.
Also, I take issue with your consistent mischaracterizations of what the literature, you yourself have linked in this thread, actually say.quote scottie:
Shapiro could reference 56 or 560,000,000,000 papers. So what? This is from a lecture at a conference, is speculative, is NOT a peer reviewed scientific work. On top of this blatant appeal to authority, you (and other ID’ers) have totally overstated what Shapiro is saying in this document, which Shapiro himself is overstating. There is nothing earth shattering in the actual science he is referencing in this document.
It’s a common tactic for creationists/intelligent design proponents to latch on to this particular document as if it totally disproves random mutation in favor of design claims. I back that statement up by simply pointing out that if search for Shapiro’s "third way" concept you find it plastered all over many psuedoscientific ID websites.quote scottie:
You have terribly mischaracterized this paper. In no way does this work refute common ancestry. It’s an attempt to reestablish the shape of the "tree of life", or even redefine it in other terms, to match the observational data. NOWHERE in the paper does the author even remotely suggest throwing out the idea of common ancestry.
This Biological Big Bang argument in no way supports design claims. The peer reviewers, however, saw the potential for this work to be misinterpreted (intentionally or otherwise).
Allow me to quote:quote :
Your design claims are not science. Wish as though you might, they just aren’t. Design infers a designer. You admit science can’t find the designer. Therefore design claims are not science. Stop claiming they are.
You also repeatedly allude to "Darwinists" and try repeatedly to make the claim that Darwinian evolution is a religion. This a tired old debate tactic of the Creationist/Intelligent Design community. It’s a way to try to equate the two (religion and the study of evolution by natural processes) even though are clearly not the same thing.
Evolution is not a religion. Your evidence that it is a religion is the zeal and conviction with which it is pursued. This logic could be applied to ANY activity, for example quilting or coin collecting. Calling evolution a religion makes religion pretty much meaningless.
The fact is, people of diverse cultural backgrounds and religious affiliations believe in evolution, yet not one of them, if asked, would identify their religion as evolution. If evolution is a religion, it is the only religion that is rejected by all its members.
About your design claims:
1) There is no "theory of design" in biology because design can’t be defined in the normal sense without also defining an agent and purpose. A theory of design must address agent and purpose or it is not about design. You admit that you do not define the agent and purpose. Therefore, even if you could somehow prove design, it wouldn’t be about design in the usual sense at all.
2) Nowhere in the scientific literature is any design theory validated.
3) The design claim is useless and unscientific, it has not generated any predictions and no scientific work has come from it.
scottie, you can go on linking scientific works and mischaracterizing until your heart’s content but you’d still be wrong WRONG wrong. All throughout this thread you’ve made this argument from incredulity about design. The problem with your arguments is that they rely on "disproving" evolution instead of proving positive your own claims. You appear to be trying to sneak in the god of the gaps whether you admit or not.
June 1, 2011 at 1:18 am #105122quote scottie:
This is an absurd attempt to discount Darwinian evolution by misconstruing Mayr. Shame on you scottie. Shame.
The effects of Darwin’s ideas on Philosophy and the founding of the well regarded science of Philosophy of Biology is clearly the sentiment of Mayr’s article. Not writing off Darwinian evolution as something less than scientific or as a something akin to religion.
Mayr is giving praise to Darwin’s theories not solely as philosophical, but in addition to it’s merit as scientific FACT. Huge difference when you compare it to what you are inferring he meant scottie.
Further down in Mayr’s article:quote :
"No educated person any longer questions the validity of the so-called theory of evolution, which we now know to be a simple fact." Sounds a heck of a lot different than what you wrote in your post right above the one I’m criticizing:quote scottie:
Darwinian evolution is not a religion. Did you just not understand Mayr, or were trying to intentionally misconstrue him? Either way your point is invalid and wrong.
June 2, 2011 at 10:10 am #105139
Darwin created the theory of the origin of new species from the former by means of natural selection. The theory of evolution – "from simple replicators to the crown of evolutionary selection", he did not create, and just trying to adjust to his theory of the origin of species.
The theory of evolution before Darwin came up as a "whipping boy", embed it in biology and used to criticize the science of being a missionary.
Darwin’s theory works seamlessly with the theory of Devolution from the initial complex engineering design to dead-end species.

Now I am going to pause here, as it is only just a start, and ask you to match my list of non-Darwinists with a comparable list of Darwinists.
For every name you put forward I will match it.
Now are you prepared to go toe to toe with me with “this absurd statement” of mine.”
I will deal with the rest of your comments but let’s first get this one out of the way.
June 6, 2011 at 3:38 pm #105177
Nice appeal to authority.
With some dead physicists and other people completely unrelated science. Is that supposed to impress anyone? Is a list of 20-something scientists demonstrating anything else than those 20-something people had view that dissent with the majority.
How do that prove that a reducing number of scientist believe something?
June 6, 2011 at 10:02 pm #105183
I said that was a start, you really need to read what I am actually writing.
How far do you wish me to go and more importantly will you be able to match me name for name.
My list was not an appeal to authority but simply to respond to freerob’s challenge to support my previous statement.
How else can I do that without naming names. I naturally assumed that to be a fairly basic requirement.
By the way those I have named were not dead when they went public, some though may have died since. Life does have that unfortunate quality.
Also as far as proof goes, just one or two of those who have changed from Darwinian to non Darwinian
is sufficient to prove my point. —— However I am not relying on just a few.
We can take this as far as you wish.
I do understand however that your need to go for any little opening you can spot since the big gates have closed in on you.
June 6, 2011 at 11:44 pm #105184
No you have not answered my question. I doubt you ever will.
As for your list the kind of data would be rather like polls telling me what percentage of scientists (I’d rather have biologist as the other are not very likely to be more than laymen in the field) support which side of the discussion. if possible with size of sample, origin and method of sampling. You know data, not anecdotes (which is exactly what a list of name is).
And since you claim a reducing number of scientists, please provide at least 2 data points (the more the merrier) to support your assertion.

Oh and define scientist.

June 7, 2011 at 10:43 am #105189
The list scottie is copying names from is most likely the one found at http://www.dissentfromdarwin.org/index.php ,a website belonging to The Discovery Institute, now calling itself the Center For Science and Culture. The leading "Intelligent Design" advocacy group in the U.S. He should have cited his source but didn’t. I noticed quite a few of the names on both lists (the website’s and scottie’s).
If that is the reference source for scottie’s list of scientists it should be noted that there are many serious criticisms of how it was gathered. Mainly through a petition called "A Scientific Dissent From Darwinism". Since the list was published, some who have signed on to it have dissented from the petition itself. Claims of being mislead into signing on to it and of misrepresentations were reported.
Only 80 of the original 700 signing the petition were biologists to answer canalon’s question since scottie tried to skate past it (if indeed this is his source, he didn’t cite a source).
All are welcome to review the wiki-article on "A Scientific Dissent From Darwinism".quote :
June 7, 2011 at 1:23 pm #105190
well done Freerob
At last some one is actually doing some homework.
As I said before and will say again, can you match name for name. Whatever the source at least these people have actually had the temerity to put their names out in public.
Do you see names such as Shapiro, or Koonin,( I will deal with your comment regarding him shortly) or Woese or any other of the evolutionary scientists who refute Darwinism. Of course not.
And why not. –because they don’t wish to be associated with ID or any other interpretation. They will critique from within but not commit the gross sin of siding with the opposition.
This is all about the "them and us" syndrome and nothing to do with facts. I will comment further on this list.
However let me move on for the moment to Shapiroquote :
Nice little bit of rhetoric but please tell me was “Origin of Species” ever peer-reviewed before publication like all good scientific papers should, or as you put it was just speculative? 🙂
However what part of Shapiro’s “essays” if you like, are speculative and overstated.
Please enlighten me.
Also can you cite any peer-reviewed paper that actually contradicts what he states as observed facts.
By the way I am not an advocate of Shapiro’s views per se, but simply quote him as an example of the divide between Darwinists themselves. He clearly does not support Darwinian theory.quote :
It may or may not be a common tactic for creationists/intelligent design proponents, but since I am neither, one or the other, your accusation lacks any power with me. Please read my previous posts.quote :
Religions are belief systems. They do not rely on factual evidence to support their beliefs. That is why they are beliefs or points of view!!! They generally rely on sacred dogmas.
Now Is Darwinian theory simply a dogma ?
Well let’s see
Species arrive by common decent through natural selection sifting out random mutations. In other words random mutations produce a phenotypic change in an existing species and then that change remains, or is discarded by natural selection.
Now lets have the evidence please in a macro evolutionary sense.
No unsupported statements of any materialist philosophy counts as evidence as you well know.
So let me turn to Ernst Mayr the root of so much of my shame 🙂quote :
So according to you Darwinian theory is a scientific fact. Yes?
Now these are the words of Ernst Mayr himself. I am not editing anything or taking him out of context. He simply argued his corner very rigorously.quote :
So if the theory is a fact why does it need a supporting philosophy?
After all, other scientific facts don’t have,or indeed need, supporting philosophies.
Newton’s Laws on gravity, Kepler’s Laws of motion, Chargaff’s rule of GC% content etc etc.
The reason is simple, it is a philosophy. Mind you Mayr also describes it as a historical science.
Now that puts it on a par with Archaeology, and we all know how exact a science archaeology is don’t we?
If you were honest enough to acknowledge that, at best this theory is a material interpretation of what is believed to have happened then there is no problem, except of course for you it is a problem, because it put this on the same level as other interpretations.
So a dictat is issued – how does Mayr put it- and you so rightly quote himquote :
So anyone who questions Darwinian Theory is not an educated person according to Ernst Mayr and you as one of his obedient acolytes simply parrots the same dictat as though it had some force.
That means that all the PHD scientists (I have already provided you with a very very small starting list of these ) who do not hold with the theory, are part of the uneducated masses.
Oh dearie me 🙂 ( It’s an english expression)
The Darwinian doctrine is a sacred doctrine that only the educated can comprehend.
Hmm!!! sounds very much like the principle driving force that was behind the Spanish inquisition.
Look if you don’t like being referred to as a religionist then don’t behave like a fundamentalist in religion.
I will take up “quote :
” in my next post.
June 7, 2011 at 2:26 pm #105193
Scottie You said you want science. A list of name is just a butterfly collection it does not say anything on the larger population, the changes over time of the acceptance of the idea or anything interesting. This not science, this is anecdote.
You claimed that there is a reducing number of scientist backing up evolution, could you provide facts baking up your claim?
You claim that life as we see it is evidence for design. If this is true, and scince design imply action by an outer agent, what would this agent be? and how did it came to be? I remind you that you were the one that first called Occam’s razor in deciding what hypothesis should be accepted. Is an infinitely recursive loop simpler to accept than "spontaneous order from chaos"?
June 7, 2011 at 4:15 pm #105197
I will respond to your post but if I may I would first like to continue with freerob’s rather lengthy series of questions.
Promise I will return to you.
Now I will take up “About your design claims” iquote :
As regards the theory of design. Please get your facts straight. Do some research on for instance the theory of C K design.
However does design feature in biology?
This is what George V. Lauder of Harvard University has to say on the subject
http://www.people.fas.harvard.edu/~glau … heoBio.pdfquote :
So please tell has any scientist refuted this statement?
In fact so profuse is the recognition that some have sought to try to remove the word design from scientific literature.quote :
What do you mean by this statement. There is plenty of literature teaching design theory. Perhaps you could be more precise. Are you saying that design is not a scientific concept?quote :
Does Darwinian theory generate any predictions? If it does then it cannot be random or undirected.
So according to your logic then Darwinian theory is also as you put it useless and unscientific.
You really need to think more carefully before engaging in your rather rash rhetoric.
Now design meets even your requirements.
Lets take the digestive system of say, yourself.
From teeth to anus there is purpose is there not.
You know the food intake goes into your stomach, gets digested, produces the necessary fuel to power the cellular processes to keep you alive.
The waste parts of the food that your body cannot use you discharge through your anus.
Now does this tract have purpose.
Answer – Yes, fundamentally to keep you alive. There are some side issues like waste discharge. It also allows you to blow hot air from time to time.
Is there a process?
Answer – Yes, you can see that process depicted in any digestive tract diagram.
But Darwinian theory has no purpose – Right?
It is undirected — Right?
So for this tract to arrive by a Darwinian process some undirected and purposeless mutation(s) would have to have taken place in the genome — Right?
Lets ignore the fact that most mutations lose information instead of gaining information.
Where does this mutation process start? Is it at the teeth or at the anus?
Or does it start with an already existing digestive system?
But that means that the already existing digestive system must also have mutated from a previous digestive system.
But wait a minute don’t all these previous systems have purpose, and function and direction, all the attributes of design.
But common decent is a major plank in Darwinian theory. Yes?
So really it is design all the way back right to the very beginning is it not?
Now could you please explain to me, an obviously uneducated person, where purposeless and undirected processes fits into this scenario.
Now I don’t want you blowing any hot air at me, just give me the FACTS – please
I need to know.
June 7, 2011 at 10:34 pm #105201
Would you be an engineer, per chance?
This is unrelated to the discussion, and will not be discussed further, but I am curious…
June 8, 2011 at 1:28 am #105202quote scottie:
There is no issue with the use of the word "design" in the above cited paper because the author clearly points out his definition of "design" as a biological structure relative to it’s function and the "designer" as adaptation through natural selection. In the introduction you quoted from, the author gives us his definition of design and designer. I probably wouldn’t use the word design to describe the result of an unguided process, however, as you point out, it’s common in the terminology. Not that the frequency of the use of the word design in any way gives it the meaning you wish it to have.
My issue is with YOUR use of the word design. You imply design in a guided manner but do not define a designer. Please clearly state your design hypothesis, including your "designer".
Using the author quoted above’s definitions, you arrive at Darwin’s theory. This is another example of you(scottie) attempting to misconstrue or mischaracterize what a cited example actually says. The article is actually really interesting if you read it. Does it refute natural selection in favor of a "design and designer"? Nope. That’s not what the paper discusses in any way, shape, or form.
Was the Grand Canyon designed? It has form and function. I suppose you could say it was if you include geologic forces as the designer. However, design is probably not the best word choice, which brings me to the article by Andrew Moore that you cited. http://onlinelibrary.wiley.com/doi/10.1 … 90011/full
I strongly agree with Moore here. I have heard others propose similar ideas and agreed to that as well. Anthropomorphic terminology is a problem, and is even evidenced by you yourself scottie. In articles you have linked, you imply such a meaning to words like design when a different meaning is what was intended by it’s author.
I’m beginning to think there is a not a difference of opinion here in this thread so much as an attempt to lead a discussion astray by deception. The strategy you have used is this: The word design is used in an article and you ascribe an invocation of an agency, even though the author clearly did not. Or, if not an anthropomorphic misconception, you take a quote and attempted to twist it into a meaning it does not have in the broader context of the entire article, what is commonly called "quote mining". It’s a form of dishonesty. Also you use terms like "Darwinism" and "Darwinists" in an almost derogatory manner. That’s an example of trying to write off the scientific consensus as mere "group-think", and it’s wrong. That’s what ID proponents do when their arguments can’t pass the scientific test. Claim the consensus is dogmatic and intolerant to new ideas.
I also want to address this nonsense:quote scottie:
Yes, evolution is a FACT. Does it need a supporting philosophy? NO. What was stated by Mayr and others was that the unifying theory of biology, evolution by natural selection, opened the door for a Philosophy of Biology. It was as indeed as profound as Mayr stated in the article you linked.
Where you get it wrong is in trying to put the cart before the horse. The science behind Darwin’s theory came before any philosophy could be built upon it. Not vice-versa as you attempt to assert. Additionally, the philosophy that arose from Darwin’s theories was/is not playing some "supportive" role in propping the theory up as you suggest. It’s how we deal with the implications of a new way of understanding the natural world around us and our role in it. Just the same as Philosophy works when applied to Chemistry or Physics or Mathematics.
What is the following quote supposed to achieve?quote scottie:
Weren’t you repeatedly accusing others in this thread of using rhetoric? Hey pot, what color is that kettle again? 🙄
You call me religionist because I’m someone who agrees with the scientific consensus and argues the merits of a theory with zeal eh? Ridiculous. Also that list of PHD’s you’ve mentioned again is a punchline more than it is a reason to take the ID movement seriously. You admit the list came from a Creationist/Intelligent design website. You claim you aren’t one of "them", but you use their propaganda on a legitimate biology forum?
Also. Your abrasive, sarcastic, and passive aggressive tone really rubs me the wrong way. The floor is yours to spread some more fallacies draped in jargon and rhetoric I suppose.

The corpse, remains under the same laws of physics and chemistry as the living animal, does it not?
The same collection of molecules exist in the animal during the moments immediately before and after death.
Yet after this transition, will you as a biologist think about genes as being regulated, or would you refer to normal chromosome functioning?.
No molecules will be carrying signals and certainly there will be no structures that will recognise those signals.
Coded information and communication in their biological sense, will have disappeared completely.
If life is simply a material manifestation of arranged molecules, why is there this complete contrast between the living and the dead animal.
Physically, they are still the same are they not?
Now you are trying hard to explain that life is just a collection of molecules arranged, amazingly, not just by some functional design, but by of all things, randomly.
Darwin privately envisioned life as starting from some quiet little pond full of the right molecules wherein life first got started.
Scientific American in it’s September 2010 article entitled “Dust to Dust” page 58 describes the process of cell deathquote :
So here is all that is needed to start life off with. As Darwin envisioned a fluid rich in nutrients and we have that postulated “little pond”.
What then do these nutrients have to do?
Well it’s quite simple really.
The nutrients separate themselves into cell walls and enzymes. But of course actually these enzymes naturally digest those very cell walls. (But never mind lets carry on)
For some reason, lysosomes form to prevent that from happening.
Then the cells start taking in carbon dioxide from surrounding fluid to release oxygen. And viola there we have it Life! 🙂
Yet, you know as indeed I know that this does not happen, despite the conditions being so amenable.
What I find hard to understand is:-
What is it about this so obvious manifestation of evidence of some force operating beyond physics and chemistry, that you find so abhorrent to come to terms with.
Whatever this life force is, science is simply unable to explain, and yet not only do you seem to refuse to acknowledge this fact that is staring out at everyone, but you so readily appear to accept the notion that somehow and quite miraculously a random collection of molecules has come together and produced a living organism that has purpose, function and behaves predictably.
Is it not obvious that this life force whatever it may be, and clearly is quite apart from physics and chemistry, has to be present before life can manifest itself.
If scientists would have some idea as to what this life force is then it could perhaps be explained, but as it is science cannot explain it.
All we know with any confidence is where this life force comes from. You know it, I know it, every biologist knows it.
It comes from another life.
Scientists cannot even provide an agreed definition of what life is, let alone explain it.
This whole controversy is not about science, it is about different philosophies or religious beliefs that are trying to deal this question.
Ernst Mayr knew exactly what he was talking about when he described Darwin’s view as an extraordinary philosophic advance.
So coming again to your repeated question, can I name the designer?,–
No I cannot, because science cannot.
Does not your own tag line go something like this “ Science is proof without certainty….”
Yet you are trying to obtain a proof with certainty from me, which of course completes your tag line, rebutting creationists.
All anyone can ever do is provide a philosophical view that will probably be different from yours.
That of course will not be a scientific exchange, it will be a philosophical exchange.
So please tell me what prevents you from acknowledging that the materialist viewpoint you clearly hold (correct me if I am misrepresenting you) cannot be proved scientifically.
Ernst Mayr proudly acknowledged it as such.
However he put himself on the pedestal that clearly demeans anyone, that has a different view, as uneducated. This sort of arrogance does indeed permeate discussions like this and it does come from all sides of the debate.
Therefore it is not possible to enter into any rational discussion with that arrogant perspective as a controlling edict.
And that, as I have said before, is not a road I will go down, simply because of the way these exchanges quickly degenerate into shrill name and cat calling.
Now if you as a moderator would wish to start a thread on this subject with the strict rule that everyone’s views will be treated with respect, then I will happily have an input.
This will also give some freeness of speech for any views to be aired without the posters of those views having to cope with the distaste of the emotional demeaning that keeps taking place.

1- There is a theory that those doubting evolution are particularly common among engineers. No explanation, just correlation. It is inconsequential but funny, and indeed very often true. the good thing is that in spite of the general very poor understanding of biology (no, you are no exception), at least the argument with engineers are slightly more interesting that with the religious crowd.
2- For your little story, decomposition of living things are usually not leading to new life, because even in the deadest corpse is teeming with life which is extremely adept at using all source of energy to its benefits. And very efficient at it too. So even if a new life form were to emerge, it would be at such a competitive disadvantage that it would disappear quickly. (Think throwing a toddler in a hungry tiger cage to compete for food….).
3- You still have not answered my one simple question.

So that’s your best argument is it?
What part of biology have I got wrong?quote :
I am not referring what decomposition may lead to.
Are you deliberately trying to miss-understand the point I was making?
My point was to try and help you to think that life is not a physical/chemical process.
Life uses physical and chemical processes and is something apart from them.
Darwinian theory in effect states that life is just a physical/chemical process and my “little story” as you put it simply shows that that is not so.
Even I, who only studied biology at college knows what Louis Pasteur proved.
Do go back to your school notes and read all about his experiments.
Or did you not learn that at school?.
Life only come from another pre-existing life.(that’s what Pasteur demonstrated and to date it has not been refuted)
Every biologist knows that, but those of a materialist philosophy then try to argue otherwise and as I have said before that number is reducing.
Of course micro-organisms (other living organisms) do infect and feed off the dead corpse, but corpse is dead and you know it. The life that was controlling that now dead copse is no longer there. It has gone, vanished , vamoosed, disappeared.:)
The biological processes in that corpse has wound down and no longer exists.
Are you seriously arguing that the dead corpse is somehow alive or with the right physical conditions could be made alive again?
Is that your contention?
Come on surely even you can do better than that.
I know, points you are unable to answer are somehow irrelevant, but only because you are not able to answer them.
You may wish to argue by issuing dictacts. That what religions do, but that only enhances my contention.quote :
Again, I have and you know it.
You ask for a name as if that matters scientifically.
You are trying to hide behind a philosophical point to advance your claimed “scientific” view.
However have you even tried to describe how random, undirected processes can account for the functionality we observe in the cell?
Other than, ofcourse stating by – dictact – that it does.
That is your problem.
You are stuck with a doctrine that you can’t explain, you cannot prove, so you have to rely on these dictacts.
I have often asked priests and clergymen to explain the doctrine of the trinity. (you know how three persons can be one person).
The answers is always the same.
Well it is. It is a FACT. 🙂

I see no difference.

Thank you for your demonstartion of your ignorance and stupidity. That will be my last post in this thread.
Just for your education, i will nevertheless that death is not what you think. When an organism dies, it does not mean that all cells instantaneously dies simultaneously. In fact, all cells will die, but some might take way longer time depending on their requirements in food and oxygen. So life is still active, but the general system is unable to perform the coordinated activities that were allowed the survival of the organism. In case of a human, that would entail respiration, blood circulation and so on. Some cells that are bad are storing energy and with high energy needs (as neurons) will die quickly when those functions cease. Other like some hair and skin cells with very low requirement will be able to keep going for weeks, in their own little corner.
As an engineer you should think of it as a very complex machine with multiple independant subsystems where the central control dies. many of the subsystems will be able to carry (some of ) their functions automatically, but without order or significance. The machine itself is dead.
As for your engineer explanation, we pretty much agree on the reason of the correlation (used to work on complex and designed system) but in my view you need to add arrogance and ignorance (of biology) to the mix to explain creationism. And you sir are are an arrogant fool. Learn about biology before you talk.
June 15, 2011 at 7:02 am #105285kathreedsParticipant
Rapid advances in the study of genetics and molecular biology have produced additional insight into fundamental questions such as the origin of life on Earth. You should write a paper that provides an overview of Genetics engineering perspective
June 16, 2011 at 11:22 am #105295
We are agreed then as you say the “machine” is dead.
Now if you had actually read what I did write, you would have understood I was describing a winding down process
I actually saidquote :
To add to the information I could have said that individual cell death takes anywhere from some minutes to perhaps a couple of days as the lack of blood flow starves the cell of the energy needed to maintain operations and so on and so forth.
However I assumed I was debating with a biologist who would have known these things.
But there you go, in my arrogance, I deemed it unnecessary.
However you do make a valid pointquote :
Indeed I have spent the last three years learning, which is why I have the “arrogance” to debate with an obviously intelligent biologist, on his own turf.
To demonstrate how much I have learned, not from my own research, but from those much more eminently qualified, I will take up kathreeds suggestion and present some of the latest research in genetics.
I appreciate you will not be saying anymore on the matter but perhaps others may be interested in what is coming to light.
I will of course support whatever I present with the necessary evidence. (as I have always done)
Thank you for your suggestion. A tremendous amount is being learned about cell functions.
One of the major areas of research is in the field of epigenetics.
The information is quite fascinating.
June 16, 2011 at 4:31 pm #105297
Since Watson and Crick identified the structure of DNA and Marshall Nirenberg along with Hargobind Khorana and Robert Holley broke the code of it, a central dogma in molecular biology solidified.
DNA codes RNA codes Protein.
DNA being the carrier of genetic information in organisms.
http://employees.csbsju.edu/hjakubowski … dogma.html
In the 1990’s it became evident that this simple concept of DNA encoding protein is not what is actually happening.
It became clear that the original length of DNA (the gene) is substantially altered before the protein encoding is accomplished.quote :
In my post of the 20th May I provided some information relating to the way a gene is modified before protein is manufactured.

It seems to me that some of you have fallen into a classic creationist trap. You can tell by “Scottie`s” ever increasing length of arguments and his arrogance and his ”boys, if you can`t follow me, I will take it slow and easy” act. He`s showing off, obviously. He`s playing for an audience and that is really the tactics for creationists nowadays. Be strictly scientific, strictly unreligious and repeat as often as possible that the idea of evolution is really a belief system. I think it was obvious when “Scottie” stated that evolution is a fact, but only within species. To say that, you have a different motive than science. I hate to see these fake debates over and over again. I think they are harmful to forums like this and to science in general.
June 19, 2011 at 10:55 am #105349
Thanks for the compliment.
It’s nice to have it recognised that I am sticking strictly to science and being un-religious.
I assumed that science is about just that.
I will therefore continue with the science and continue to keep religion out of the discussion.
Is the DNA sequence the Master controller of the cell?
We all begin life as a single cell containing an entire genome.
As the cell divides the chromosomes are faithfully replicated so that each daughter cell receives the same genome (There are some exceptions to this. For example in the human immune system.)
So how is it that the daughter cells then go down different pathways leading to different tissues in this process of differentiation?
The offspring of one cell will eventually gain the ability to expand and contract as part of a muscle, while another will take on a rigid form with a specialized ability to transmit electrical signals etc etc.
In the human genome there are about 200 different cell types..
This instruction set (genome) apparently does not contain all the instructions needed for cell growth.
These instructions are extra or above (epi) to the genome.
Now there is also another factor worthy of consideration.
The result of the Human Genome Project posed another problem.
It was expected that the human genome would contain about one hundred thousand protein coding genes. Instead it turned out to be only about twenty odd thousand.
This number is roughly about the same as a simple one millimeter long roundworm.
Genes are therefore far from the whole story.
Most of the human DNA (some 98.8%) does not code for proteins. The bulk of this non coding DNA was referred to as junk i.e. the evolutionary accumulation of meaningless genetic leftovers.
However as more information has surfaced an intriguing picture is revealed.
Non coding DNA accounts for only 10% of a one celled prokarote, only 32% in yeast, 75% in roundworms, 83% in insects, 91% in a pufferfish.
The more complex the organism the greater is the amount of this “junk”.
This is highlighted in this paper
http://onlinelibrary.wiley.com/doi/10.1 … 4/abstractquote :
The above is a direct quote from the above abstract.
So we have gone from “junk” to the primary measure of our evolutionary advance, as organisms have got more complex. 🙂
So a reasonable question to ask would be.
How does Darwinian theory of random mutations of the genome explain this 98.8% “junk” in the human genome and which incidentally is distinctly non-random?
This is how cell biologist Lenny Moss reviews the situation in his book “ What Genes can’t do”
Once upon a time it was believed that something called “genes” were integral units, that each specified a piece of a phenotype [that is, a trait], that the phenotype as a whole was the result of the sum of these units, and that evolutionary change was the result of new genes created by random mutation and differential survival.
Once upon a time it was believed that the chromosomal location of genes was irrelevant, that DNA was the citadel of stability, that DNA which didn’t code for proteins was biological “junk,” and that coding DNA included, as it were, its own instructions for use.
Once upon a time it would have stood to reason that the complexity of an organism would be proportional to the number of its unique genetic units. (Moss 2003, p. 185)
http://books.google.com/books?id=AGm7Tg … ss&f=false
The evidence now is that the resources for the management of cell functions reside, in part, in these non-coding protein areas as well as other areas distributed throughout the cell.
Some recent experiments show how important the role of RNA is in phenotypic variation.
I will point to evidence next.

I am not sure if Scottie is being harmful. He sure is not debating, as his constant refusal to answer my simple question demonstrate, and he is long winded and not very interesting.

So pointing out that his argument of design is essentially circular (nothing can be without design, so there must be a designer that is something [back to start]) is essential.

June 21, 2011 at 10:20 pm #105373quote :
Who needs a diary when the evidence is publicly available.
Canolan’s question has been answered.
It is just that he does not like the answer so he invents arguments about circular reasoning.
His problem is that he has not asked the scientific question.
So let me help
How about this most important one.
Is my understanding of Functional Design falsifiable?
Now this would be a reasonable question.
But of course he is unable to argue scientifically,so he tries to get me to name the designer, as if that has some scientific merit.
But that is his only bolt hole so I suppose he has to dive into it.
So lets deal with what would falsify design hypothesis and also what would falsify the neo-darwinian theory.
For a theory to be scientific it must be falsifiable.
Yes? no one is going to argue with that are they?
Lets start with my view.
We all see functional design in the cell and no one seriously argues with that.
The question is how did this functional design come about.
My understanding is that an outside agency is responsible.
To be regarded as science then it must be falsifiable.
So once again, is this understanding falsifiable?
I answer Yes, it can be falsified, and there is nothing “secretive” about this.
Every one is aware that functional design (whether good, or not so good or even downright bad) displays itself with certain properties.
1) The function has a purpose. ( i.e. It goes from A to B with C as it’s goal )
2) Method by which that purpose is achieved. (How does it go from A to B)
3) It would not contain parts or units that had no function toward the purpose.
Therefore, falsifying this hypothesis would require that parts of the genome were non functional. Now if that was the case then that would be an argument against my hypothesis.
So, all you have to do provide evidence that any part(s) of the genome are non functional and my hypothesis is in trouble.
There you are, I have told you what you need to show.
Should be quite simple, shouldn’t it?
Now, the Darwinian or the neo Darwinian view is that this functional design has come about by random mutations of the genome filtered by natural selection with all life having developed from a common ancester.
If this theory is to be regarded as scientific then again it must also be falsifiable.
So What would falsify this theory?
All you need to do is simply reveal what would be required to falsify this theory.
Darwin himself has made some clear statements in that regard in his “Origin of Species.” So you should have no difficulty.
So lets keep all the philosophy, religion, and misrepresentation of my posts out of this discussion and cut to the chase.
Come on canolan,
I know you don’t wish to continue debating with me but surely even you can rise to this simple challenge.
After all you are the biologist and I am but (how did you put it?) an arrogant fool 🙂
btw. I will continue pointing to more evidence on epigenetics.
June 26, 2011 at 7:13 am #105405AbeParticipant
I just noticed this post today and it seems interesting. So if i understand u correctly Ur not saying evolution doesn’t occur just that it doesn’t occur randomly. is this what ur saying?
June 27, 2011 at 9:12 pm #105414
Thank you for your question.
I joined this forum on the 12th April. My first post is here.
48 posts later, along with a certain amount of abuse being directed towards me, 🙂 has resulted in an unanswered challenge.
The theory of design is a valid scientific theory simply because it can be falsified.
I have shown how it can be falsified and it has resulted in my challenge to do just that.
I am waiting for someone to inform how the Darwinian theory can be falsified.
It has to be falsifiable if it to be counted as scientific.
Things have gone silent on both fronts.
So to recap for your benefit and answer your questionquote :
There is good evidence that evolution (variation) does occur, but only within species.
There is some accumulating evidence that undermines this process as purely random.
The field of epi genetics is beginning to show this.
I have been arguing that the (Darwinian or neo-Darwinian) hypothesis, random mutations filtered by natural selection from a common ancestor is not supported by the evidence we see in the functioning of the cell.
I have contended that design is the correct understanding of how the cell appeared.
I do not support either the creationist or the ID understandings as I have found difficulties with them both, although I have not explained my reasons, simply because this debate has been around Darwinian hypothesis or evolution as it seems to be commonly called.
Hope that answers your question.
July 1, 2011 at 12:05 pm #105446
Some further evidence that impacts on Darwinism
Firstly by way of some basics for us non biologists!!
Chromosomes normally come in pairs in the genomes of mammals. One is inherited from the mother and the other from the father. So any given gene occurs twice, with one version or "allele” located on the first chromosome of a pair and the other on the second.
When the two alleles are identical, the organism is said to be homozygous for that gene; when the alleles are different, the organism is heterozygous.
As an example, there are mice that in their natural wildtype state are dark-coloured.
This colour is partly dependent on a gene known as Kit. These mice are normally homozygous (i.e. both alleles are identical) for this gene. However, when one of the Kit alleles is replaced with a certain mutant gene, the now heterozygous mouse developed white feet and a white tail tip.
Now when these mutant mice were bred together, some of the offspring were again normal wildtype, which would be expected.
However these normal wildtype mice maintained the same white spots that were characteristic of the mutants.
Mendel’s laws of inheritance were apparently being violated.
A trait was being displayed despite the absence of it’s corresponding gene. Something epigenetic was going on in the inheritance of the offspring.
It appears that RNA is playing a role in this inheritance across generations
http://cambridge.academia.edu/AlysonAsh … enerations
This is further evidence that DNA is not the only information set that the cell is using.
Now why is this important for theory.
It is because Darwinian thinking has centered on the genome as being the driver for phenotypic change. Gradualism being the operative process.
However the evidence is, that the cell as a whole determines what an organism is. Neo Darwinism has no answer for this.
One of the most outstanding examples is the caterpillar and butterfly. Both organisms have the same genome, yet how different they are in phenotype and all this change takes place within about two weeks.
I will of course provide more evidence of this epi genetic control that is rapidly coming to light.
July 1, 2011 at 1:11 pm #105447
First of all, Darwin had no idea about DNA. At the time, when he lived, the DNA was not known yet, especially not as an inheritance material.
Second, all of your cells contain the same genome, yet they are different. However, that’s not epigenetics, only regulation of genes. Nevertheless, this has nothing to do with evolution.

However perhaps you could describe to me what you mean by evolution. If it is the standard neo Darwinian process then it has everything to do with evolution theory.
However you may have a different view of evolution. Do you?
Epi genetics is the study of control other that genomic control.
That is what epi means — extra or above.
Also you are correct. Neither epigenetics nor gene regulation have anything to do with evolution.
The whole point that I am arguing is whether these control mechanisms came about by random mutations of the genome from an existing organism.
The theory of “evolution” says it does and I am arguing it does not.

The Universal Code Dilemma of Darwinism.(or however Genotype would like me to refer to it as)
In 1986 Richard Dawkins (The selfish gene) claimed that the genetic code is universal across all organisms, and cited this as evidence, indeed as near conclusive proof that every living organism in our planet descended from a single common ancestor.
In his 2009 book The Greatest Show on Earth he reiterates this claim.
“the genetic code is universal, all but identical across animals, plants, fungi, bacteria, archaea and viruses. The 64-word dictionary, by which three letter DNA words are translated into 20 amino acids and one punctuation mark, which means ‘start reading here’ or ‘stop reading here,’ is the same 64-word dictionary wherever you look in the living kingdoms (with one or two exceptions too minor to undermine the generalization)”
He goes on to explain why this is important.
Any mutation in the genetic code itself (as opposed to mutations in the genes that it encodes) would have an instantly catastrophic effect, not just in one place but throughout the whole organism. If any word in the 64-word dictionary changed its meaning, so that it came to specify a different amino acid, just about every protein in the body would instantaneously change, probably in many places along its length. Unlike an ordinary mutation…this would spell disaster. (2009, p. 409-10).(my emphasis)
Is Dawkins correct?
If the Darwinian mechanism is true then yes, he is correct.
However is that mechanism correct?
There are in fact 17 known variations of the genetic codes that have been compiled by the National Center for Biotechnology Information.
http://www.ncbi.nlm.nih.gov/Taxonomy/ta … =cgencodes
Not one or two minor exceptions but at the latest count 17.
And are they minor?
Well take the organism Mycoplasmas.
The stop codon in the human code is UGA
In Mycoplasmas UGA codes for tryptophan.
In human cells therefore when the ribosome meets up with UGA in the messenger RNA it stops translating. (UGA is code for STOP)
In Mycoplasma the ribosome would insert tryptophan into the mRNA and would continue translating until it reached the Mycoplasma stop codon.
Is that serious?
Well Craig Venter explained it well to Richard Dawkins and Paul Davies during a discussion at Arizona State University earlier this year.
Watch here from about 6min:30sec to about 11min:45
http://thesciencenetwork.org/programs/t … life-panel
Contary to what Richard Dawkins believes There is no tree of life. .
This is from a bio-engineer who knows what he is talking about. At least Paul Davies concedes to Venter.
Dawkins however is really troubled about this.
Listen carefully to his response to Venter and Venter’s polite chuckle.
In my next post I will show how the Darwinian mechanism fails to show how a prokaryotic cell could have evolved into a eukaryotic cell
July 11, 2011 at 11:21 am #105533
Hmmm. So, once, a few billion years ago created a reasonable membranes, standardized first version of the peptide-nucleic molecular technology, and armed with her, travel to the Metagallaktik. Then somewhere a bit more than once the standard has changed, but the basics remain the same. But the main thing – the version of Darwinism, according to which natural selection is combined not with the "Evolution" – from simple replicators to the "crown of creation", but with vice versa, the "Devolution" from a reasonable universal form – to super-specialized species of dead-end.
Excuse me my inglish Google 🙁

As I understand, you appear to dispute the Darwinian theory yourself.
I wish I could do as well in Ukrainian as you do in English.
Thanks for your response.
My apologies for not responding sooner but I have been away and am only just catching up on things.
Lets start with some sources of (neo)darwinian theory
In part this source statesquote :
It goes on to describe challenges to this theory, in particular by Gould where it quotes Gould in partquote :
There are perhaps differing views at the edges of this but the foundation pillar is the random mutation of genome filtered by natural selection from a common ancester and that this process is gradual. You just have to read Dawkins, Coyne and indeed others to note that gradualism is prominent. Small incremental steps of random change.
Also try this
Sorry you are having trouble understanding my posts. I will try and be a little clearer.
My reference to metamorphosis simply illustrates that changes in phenotype do not require changes in genotype as the theory states. Something else is at work.
This contrasts with the Dawkin’s "selfish gene" and "mount improbable" for instance.
Good to hear you are a Newtonian. He did get a lot right. 🙂

Yes? Ukrainian? And I try to write in Russian … This is very good. I can easily understand what translate Google from English! Then take a look here is more!
We almost all remember from biology: "ontogeny recapitulates phylogeny." This is according to the theory of evolution. And from the standpoint of the theory devolution – "ontogeny repeats metamorphosis of primary universal amphibians". From the standpoint of those of amphibians, our "embryo" – it’s unfortunate larva, devoid of happiness independent existence during the most exciting stages of childhood – from the stage myuller-larve! 😀

Nice sense of humor. I must remember that one. 🙂
Please read my post in it’s entirety. I responded to your request to provide citation..
I did with the direct quote from “A Neo Darwinian commentary of Macroevolution”
That very specifically statesquote :
Now if you disagree with that postulate then your disagreement is not with me but with the authors of the commentary.
I also did state very clearly thatquote :
So I standby my statement.
The whole interest in the study of epigenetics is precisely because the understanding that mutations of the genome are the driver for the theory is rapidly being eroded.
Why else are distinguished scientists like Margulis, Koonan and many others distancing themselves from the neo-Darwinian hypothesis ?
Richard Dawkins “Selfish Gene” recounts a gene centric view of change.
In his book “Climbing Mount Improbable”
Well —Wikipedia describes the book this wayquote :
If you read the summary of the modern synthesis you will note that the again the evolution of species revolves around gradual genomic changes.

I would now like to continue
The theory of common descent, simply postulates that all life evolved from one kind of organism and that each species arose from another species that preceded it in time. Each group of organisms shares a common ancestor.
The prokaryote cell is postulated to have arisen before the eukaryote cell.
http://evolution.berkeley.edu/evolibrar … mbiosis_03
This is a challenge to the standard theory because random mutations in the genome is clearly not the answer.
Therefore how does, or what is the mechanism that turns a cell without a nucleus ie a prokaryote into a cell with a nucleus a eukaryote. There are some similarities between the two types of cell, however there are also many other differences as well.
This is where the Endosymbiotic theory enters, to postulate the mechanism by which this all came about.
http://www.biology.iupui.edu/biocourses … osymb.html
The Endosymbiotic Theory first postulated by Lynn Margulis in the 1967.
However Lyn Margulis rejects the Darwinian mechanism of random mutations and Natural selection.
http://discover.coverleaf.com/discoverm … pg=68#pg68
So let’s take her starting point.quote :quote :
When you read the above it all sounds very plausible.
So What is the actual evidence?
The simple answer is there is none.
Just check out the papers listed below.
http://www.sciencedirect.com/science/ar … 6888900228
http://www.sciencedirect.com/science/ar … 3779902382

What we do have is an awful lot of speculation.
The fuel for all this speculation is simple to understand.
Life could not have got started naturally in an atmosphere that contained oxygen.
Any schoolboy chemist would be able to explain the chemistry of why that cannot happen.
I could of course go into the physics and chemistry of this should anyone wish to dispute this. In fact I would welcome someone to rebut this.
This theory therefore falls at the first evidential hurdle.
My point is simple. Someone needs to produce some evidence other than tall tales about what may have led to an early earth atmosphere containing no oxygen.
Speculation is not science.
Of course there is a lot more but lets leave that for another post.
July 18, 2011 at 1:19 pm #105633
Yes, you’ve collected all the basic propositions around which is a long argument. It’s all about, I repeat once again – in the synthesis of the theory of evolution (from simple replicators to "crown selection") and natural selection. But personally, I abandoned this "evolution" and replace it with "devolution"! And this "Darwinism" was stable enough! http://translate.google.com/translate?h … ge_id%3D82
That think is IRREVERSIBLE the loss of a free stage for larvae placed our "embryo" in the egg, then – in the genital tract for pregnancy. But the frog "embryo" is placed in the egg stage only with fish (Turbellaria And today, there is also a form of free-floating planula!)! Hence, the ancestors of amphibians also have the same nymphs in their voluntary metamorphosis! But this is Stegocephalia! So, coelacanth, then ihtiostega, akantostega – this is not adult organisms, but the intermediate stages of metamorphosis Stegocephalia! Oh, how we lie to many paleontologists for this silly theory of evolution! 😛
A modern fish, respectively – the victim of neoteny as the axolotl, in which the land morphology all lost. But in flatworms (parasite – fasciola) stage of the fish – adolescariae …
July 18, 2011 at 1:56 pm #105634
scottie: you are again and again providing just piece of information so that it looks nice for your picture, right?
The endosymbiotic theory does not say, how eukaryotes evolved, but how did we obtain the mitochondria and chloroplasts.
The actual evidence are genetic data of plastids, mitochondria and bacteria. It has nothing to do with the oxygen level.
I’m sure that you are much more than a schoolboy chemist, so you will be for sure able to explain to me, why couldn’t life evolved, right? And NO LINKS! I won’t read any links, I won’t read anything what you won’t type by yourself into this forum, so stop posting plenty of articles. Noone is reading that anyway.
July 19, 2011 at 7:54 am #105643
So the answer to these questions from the perspective of macro-devolution !
You know, as different from each other different "experts" in the termite hill? And termites – it’s obviously – a relic of the paleo-civilization. Cells in multi-cellular organism – and it’s so clear. Too – an obvious relic paleo-civilization! Well, some specialized Protista – members of the first communities of myxomycetes more billion years ago – had a specialty: work with photosynthetic bacteria. A mitochondrion domesticated even earlier – to multicellularity! Planted this bacterium in a membrane interesnub pocket and used as a generator … Spent the most appropriate selection of the mitochondria … Then plastids selected such that proliferated in the membrane pockets, but chloroplasts evolved into active only at a special incentive-team. And – "Cambrian explosion"? Also a consequence of some of the early Cambrian paleo-civilization! Twists in the caste society with a global division of labor morphological polymorphism … Then different castes in a separate race, species.

That is what any rebuttal is all about.
If you disagree with me then you should do likewise. Rebut with evidence.quote :
A prokaryote cell is a cell without a nucleus or other membrane-bound organelles
A eukaryote cell contains structures enclosed within membranes. These structures include a nucleus that contains dna, a mitochondria that also contains dna or likewise chloroplasts.
Now you should have noticed that I provided two citations in introducing the theory. The first that does not mention the early conditions and the second that does postulate the early conditions.
In fact the first from Berkley is entitled “From prokaryotes to eukaryotes”
Pretty clear I would argue.
My critique of the theory cantered on the early conditions, and the speculation that surrounds those conditions.
I would encourage you to read carefully what I have written.
This is where the Endosymbiotic theory enters, to postulate the mechanism by which this all came about.
My criticism was about the mechanism (i.e. the endosymbiotic idea).
Endosymbiotic theory encompasses all the organelles that are enclosed in membranes.quote :
The theory is about the origin of the organisms. I am surprised you miss such an obvious point. This thread is all about theories of origins.quote :
For sure I do have fond memories about my schooldays 🙂
My last 50 odd posts have dealt in some detail how life could not have evolved in the way it is being promoted.
I appreciate you don’t like citations, however without citations I would simply be positing personal opinions. Science advances through proper documentation of research and therefore citations are important in explaining scientific matters. I would encourage you to read any accredited citation in order to fully appreciate,that any statement does have proper support.
I will therefore of course continue to support my statements with proper citations. Whether you choose to read and check them out is for you to decide.

I was not aware that this forum catered for advertsiments.
Genotype wants me to provide citations and you don’t want me to.
So what I suggest is that you read my posts that don’t include citations and Genotype read those with citations. That way both of you will be more comfortable. 🙂
This one is for you .
Let me try and consolidate my views as to why life could not have evolved by any natural process but as a result of design by an outside agency.
By evolved I mean some chemical combination of molecules (non life) somehow turning into some living organism.
This life in turn changes into other forms of life due to random processes acting on the organism
Let’s take the supposedly simple prokaryote cell.
This cell is hundreds of times smaller than the period at the end of this sentence.
There is a tough, flexible membrane that acts something like a brick wall surrounding a factory. It would take some 10,000 layers of this membrane to equal the thickness of a sheet of paper.
But this membrane wall is no simple brick wall.
This membrane shields the contents of the cell from a hostile environment, however it is not solid. It allows small molecules such as oxygen to pass in and out but blocks larger and more complex molecules from entering without permission. It also prevents the useful molecules within the cell from leaving.
There are special protein molecules embedded in this membrane wall that act like doors.
Some of these proteins have a hole through the middle that allow only certain types of molecules in and out of the cell.
Other proteins are open on one side of the membrane and closed on the other.
They have a docking site shaped to fit a specific substance, so that when the particular substance docks, the other end of the protein opens to allow the cargo through.
As you should already know this activity is just a very small part of the protective wall surrounding even the simplest of cells.
Now I don’t need to go into any further depth to ask some simple questions
Does this membrane (wall) have a purpose? Answer — Clearly yes
Does it have function to fulfil that purpose? Answer — Again yes
Does it have predictability, i.e. can we know what will and what wont be allowed through? Answer — yes.
Are these all the attributes of design and with a specific purpose by an outside agency?
Again the answer is yes, with the proviso that nothing else can explain these attributes.
So, is there another possibility?
If you contend that there is then please explain what that can be.
Now I have asked for those who disagree with me, and that includes both you and genotype, to put their own viewpoints or theories forward so that they can be scrutinised.
Nobody — including you, has come up with any explanation that you may wish to be held up to scrutiny.
So why not?
There is a concept that is referred to as “wilful or deliberate blindness”
Is that what is going on here?

For those who accept citations in support of posts.
Accordingly to Freeman/Herron’s Evolutionary Analysis Chapter 17, there are currently about 4 different hypotheses regarding Origin of Life.
http://wps.prenhall.com/esm_freeman_evo … index.html
Here they are with their comments in an end of chapter summary questions.
"The "universal gene-exchange pool" hypothesis proposes a time when genomes were modular, and when organisms assembled their genomes from a common pool. It is not yet clear whether this system is stable and feasible, or whether it could give rise to Darwinian natural selection.
The ring-of-life hypothesis proposes that eukaryotes arose from a fusion of archaeans and bacteria. However, this hypothesis cannot explain where eukaryotes got their unique genes, and how fusion could have occurred in the two groups that lack a cytoskeleton.
The chronocyte hypothesis proposes that eukaryotes arose from a long-vanished lineage of "chronocytes", one of which engulfed an archaean that became the eukaryotic nucleus. No such chronocytes exist today, but perhaps the eukaryotes’ unique genes represent a remnant of the genome of a chronocyte ancestor.
Finally, the "three viruses, three domains" hypothesis integrates viruses into the picture, proposing that (a) viruses are a remnant of the RNA World, (b) viruses evolved DNA during arms-race coevolution with their hosts, and (c) three such viruses then converted the three domains from RNA to DNA. Evidence from viral genomes offers a modest amount of support for this hypothesis, though more viral genomes are needed to thoroughly test the hypothesis.
These four hypotheses offer creative and varied ideas for the solution of the puzzle of life’s origins. Which of these four is true, if any, we cannot say yet. But the more we learn, the more it appears that the early history of life on Earth was strange indeed."
You will notice that they all begin with a premise that life is already in existence.
So for a start this analysis has nothing to do with actual origin of life.
What is really interesting however is that one of these hypothesis has had to invent a new life form as a starter for the hypothesis.
It is called the chronocyte. 🙂
What is more interesting is that this mythical creature is actually the subject of a paper that appeared in PNAS entitled
The origin of the eukaryotic cell: A genomic investigation
http://biologia.uab.es/biocomputacio/tr … 20endo.htm
So here we have an august scientific body resorting to or endorsing mythical creatures to try and substantiate scientific ideas.
Is this what science is being reduced to?
August 1, 2011 at 7:44 pm #105781
There is a body of opinion within this debating controversy that argues this way.—
The Darwinian evolutionary process does not engage with origin of life scenarios, but only addresses how an existing organism has changed in form and function to produce the variety of life forms that exist today.
The process that achieves this is the random variations of the genome that change form and function and is then filtered by Natural selection.
The problem that even this argument has is, it fails to account for the actual observations we note in cellular processes.
What is being discovered in cell investigation is not just a linear array of code in DNA, but a total integrated information processing system.
We are learning that DNA is not even nearly the whole answer.
DNA codes for proteins that do the important work in the cells.
These proteins though have to be arranged into more complex or higher cell structures
Cell types then have to be arranged into tissues.
Tissues in turn have to be arranged into organs.
These organs in turn have to be arranged into entire body plans, the forms we see in life.
These higher forms of organization are not fully understood, but it is clear that there are higher orders of information in the cell that are above DNA
DNA does not control all those higher orders of information.
DNA codes for proteins.
So there is this information hierarchy in the cell, and DNA is at the lowest level.
So clearly DNA alone does not control the formation of body plans.
Now the problem for the neo Darwinian synthesis (the modern theory of evolution in any of it’s forms) is that this theory attempts to describe how random mutations in DNA (the lowest level of information in this hierarchy) is responsible for new biological forms.
Since DNA alone is not responsible for biological form, no amount of mutations, random or even otherwise can produce new organisms.
This is why this materialist Darwinian concept is defunct.
It can’t account for the origin of form let alone life itself.
It is therefore very clear to me why I have had no responses to my repeated requests from those critical of my postings, to put on record what their actual scientific understanding is on this subject.
Sorry I must correct myself here, one critic did accuse me of lacking imagination. 🙂
Evolutionary theory is a materialist philosophy and not a scientific concept.
August 5, 2011 at 12:27 pm #105839
Following on from my post on the hierarchical layers of information in the cell, further information on this has emerged in recent years.
There is the phenomenon of “quorum sensing”.
This is a mechanism by which bacteria communicate with one another.
The purpose of this communication is to establish the population density of a species of any of these micro-organisms within a local environment.
A single bacterial cell that secretes a toxin into an organism is not likely to cause any harm to the host. However if there are sufficient numbers around a host, joint expression of the toxin is more likely to have the desired effect.
In other words this communication allows bacteria to collectively regulate gene expression.
Professor Bonnie Bassler of Princeton University gave a TED talk recently where she explains this phenomenon far more interestingly and in layman terms.
Well worth watching.
http://www.ted.com/talks/bonnie_bassler … icate.html
When you have watched this you may well wonder what Darwinian process led to this coordinated activity. 🙂

Evolution is a scientific fact – this is not an opinion, there is a plethora of evidence that validates that statement.quote scottie:
You have the stink of a Creationist that is merely trolling this particular topic thread.
August 6, 2011 at 8:21 pm #105848
I produce evidence from accredited sources and you respond with philosophic and defamatory rhetoric.
Is that your best argument? 🙂
Which part of "evolution is a fact" as you put it, is a fact?
August 6, 2011 at 8:46 pm #105849
August 6, 2011 at 11:29 pm #105850
From your supplied link
This is how Kellogg introduces his proposal.quote :
His first sentence clearly states the best documented aspect of evolution is “ change with respect to time of characteristics of a species.
Are you not aware that this change is within a species.
I am not aware that anyone disagrees with this micro evolutionary change.
Not even creationists as far as I am aware.
May I encourage you to read what I have written, not what you think I have.
Kellogg clearly recognised this and that is why he in this paper agrees with Eldridge and Gould on their “proposal” of punctuated equilibra
So he doesn’t agree with gradualism but prefers punctuated equilibrium.
Again are you not aware that these are proposals or hypothesis and not fact as you have so confidently asserted
Let me refer you to his website here
http://www.geology.um.maine.edu/user/Da … blications
This is what he states are his interests
My interests are in three fields of study:
1. Evolutionary Biology, particularly the tempo and mode of evolution. I pursue the long continuous records of siliceous microfossils in deep-sea sediment cores to test hypotheses about the rate and timing of morphologic change – is it continual, continuous, or episodic; what does that tell us about the nature of evolution at and above the species level? I am also interested in the more purely philosophical questions of species individuality, and the ethical implications of evolutionary biology…….
Notice he presents his hypothesis. Of course he is not sure whether change is continual, continuous, or episodic.
Now if you wish to present hypotheses as facts then may I suggest you get a clearer understanding of the meaning of terms used in science.
August 7, 2011 at 8:09 am #105856
how does the DNA thing and quorum sensing provide proofs against evolution?
August 8, 2011 at 8:49 pm #105875
May I refer you to my post below.
by scottie » Mon Aug 01, 2011 7:44 pm
There I explained that there are different levels of information that govern cell processes.
The DNA coding resides at the lowest level and codes for protein.
Above that, is a level of information that differentiates into cell types that then have to be arranged into tissues.
We don’t know where the information that controls this process resides.
Above that then, we have information that controls the arrangement of the tissues into organs
We we don’t know where that information resides.
These organs then have to be arranged into body plans, the forms we see in life.
Now these higher levels of organization go beyond the DNA level.
In other words DNA does not control these higher order processes.
DNA controls the form and expression of proteins.
This is why changes in DNA (however incurred) can only alter the protein level.
Now Darwinian theory ( I have to assume that you subscribe to Darwinian theory) only deals with mutations to DNA.
Therefore you can mutate DNA as much as you like and no new forms of organisms will arise.
Quorum sensing is just another demonstration of the higher orders of information that control cell processes.
In fact it appears that the information being used is above even cell level.
You will have noticed that Bonnie Bassler explained that there is communication not just between bacteria of the same species but also between different species.
All this information is quite definitely not being controlled by DNA.
Therefore evolution theory of any description that is based on DNA modifications simply cannot account for the forms and communication levels we see in nature.
What makes these theories even more unrealistic,is that they are all firmly rooted in the notion of random modifications of DNA.
Yet all over we see highly non-random structures.
I have covered this is previous posts.
It is not my intention to destroy anyone’s belief. People have different belief systems and I feel they should be respected even if one disagrees with them.
The problem evolutionary theory has is that it is portrayed as a scientific fact, and has been made into a dogma that has to be obeyed.
Anyone who dares to oppose it is branded some sort of a heretic.
So if something is portrayed as a scientific fact then it has to be shown to be so using known science. If it can’t be then it is simply another philosophy.
Clearly evolutional theory fails in this regard, as I have been trying to show over these past months.
The creationists are also entitled to believe whatever they want to and I also believe that their view should be respected.
However if they (and many of them do) claim that the universe was created in 6 24 hour days because the genesis account in the bible states that, then I have to take issue with that as well. There are other issues as well.
The genesis account says nothing of the kind and I suppose in due time I will be called on to prove it.
Now as regards the ID community.
Well, while they have a lot of good science they call upon, I again find there is not a consistency in their composite view.
I can go on to explain if asked, but I think this posting is long enough.
Hope that answers your question.
August 9, 2011 at 6:07 pm #105881WinterImpParticipantquote mcar:
Please correct me if I’m wrong on this, but aren’t all known viruses parasitical? That is, they are basically reproductive molecules that require the use of another organism’s host cells to replicate themselves. The virus takes over the cell’s own DNA and causes it to replicate the virus instead. If that’s so, then the first organisms couldn’t very well have been viruses. Am I missing something?
August 10, 2011 at 6:26 pm #105894
No you are not missing anything.
Wikipedia describes a virus this way
“Virus particles (known as virions) consist of two or three parts: the genetic material made from either DNA or RNA, long molecules that carry genetic information; a protein coat that protects these genes; and in some cases an envelope of lipids that surrounds the protein coat when they are outside a cell.”
How is the protein manufactured? — In a cell
Since a cell is required to manufacture protein, how on earth can anyone postulate that virus could have appeared before cells.
All this speculation is nothing but just that.
There is no science behind all this.
August 14, 2011 at 11:12 pm #105923
The scientific merit of the Darwinian macro evolutionary account in all it’s forms, as the accumulating evidence shows is rather tenuous and unravelling rapidly.
There is fierce resistance but that can only last so long.
What about the Genesis account, which is the other main view?
Firstly it is important to recognise that the account is presented as a historical narrative as
Gen 2:4 clearly states.
“ This is the history of the heavens and Earth in the DAY of their being created. in the DAY that God made earth and heaven.”
The word day (Hebrew yowm) is used 15 times in the account and it’s meaning varies depending on the context.
It varies from the distinction between light and darkness (night and day, i.e. roughly about 12 hours) to and unspecified creative period, finally to all the creative periods together, as the quote above clearly demonstrates.
Now the creationist (in particular the young earth) view is that the days mentioned in the account represent 24 hour periods.
There is no internal evidence that this is so. In fact there is nothing in the account to warrant an understanding that these created days were literal 24 hour periods.
The 24 hour period for each creative day is clearly a dogma and not based on evidence.
However can any part of the account be analysed scientifically?
The first 8 verses relating to Days 1 and 2 simply cannot.
However the process attributed to day 3 is interesting.
Vrs 9 & 10 reads
And God said, Let the waters under the heaven be gathered together unto one place, and let the dry [land] appear: and it was so.
And God called the dry [land] Earth; and the gathering together of the waters called he Seas: and God saw that [it was] good.
Current scientific understanding does seem to support this statement.
The evidence below shows that current science agrees that the landmass of the earth was all in one place in the past.
http://www.time.com/time/magazine/artic … 74,00.html
There are some other points worthy of note but I will leave that to another post
August 16, 2011 at 9:55 pm #105949
Finally showing your true color and answering to the question, you take the christian god for the creator.
Would you provide evidence that the genesis account is the other main view. I seriously doubt that.
And how cute it is to see you cherry picking verse to shoehorn science in that view. So a few more questions:
– Why Genesis 2, and not Genesis 1? Both chapters contain a creation myth.
– But they are diffrent so I do you chose which is more true, considering that, as you handily provide evidence for (at least for Gen 2), the link with our scientific understanding of the creation of the earth is quite hmmm…. patchy, shall we say?
– Do you know your Geology? And do you read your links? Because Pangea was not the first mega continent, and it is probably impossible to say waht the first continent or group thereof looked like.
But at least we can agree on something, your post on the origin of virus is correct. Since they are parasites and cannot self replicate, virus cannot be at the origin of life.
August 17, 2011 at 2:54 pm #105961
Glad to see you have come “alive”again.
You had gone very quiet recently, mind you it came as no surprise to me since your previous arguments fell apart.
Whatever happened to your last comment on this thread, remember thisquote :
But you are alive again so let me remind you that you still have not put to record which evolutionary account you subscribe to.
Why are you finding it so difficult to respond to such a simple question?
Well I am not going to hold my breath on any response on this.
However let me deal with your assertions one by one.quote :
(btw. my favourite colour is green, I have a suspicion yours will be gravitating toward red. 🙂 )
First of all I was providing an answer to MY rhetorical question.
The genesis account refers to the God of the Hebrews, not to your so called “christian god”.
A good piece of advice is to know your subject before you start making strong assertions.quote :
No no be in no serious doubt at all.
The creation view is most definitely the other main view of origins with the main creation account found in genesis.
Why? here is the reason.
Tell me do you attack with the same disparaging comments anyone espousing a different view from Darwin’s hypothesis but still positing a materialist stand?
Ofcourse you don’t.
There could of course be a couple of reasons for this
(a) you are not really sure what your own view is, which I suspect is the case since you are so reticent to put it to record. But also
(b) it doesn’t really matter to you what is proposed so long as that view does not interfere with your philosophy.
I have repeatedly made the point that these materialistic hypotheses are grounded in a philosophical view and not a scientific one. Prove me wrong.
Now just state quite clearly what your view is and the scientific basis for it and we can then examine the veracity of it.
Don’t keep catcalling from the sidelines. It demeans you.quote :
Because there is only one creation account in genesis.
The creation account of chapter one ends in chapter 2:4.
Now before you go ahead and display any more lack of understanding on this subject I would advise you to get at least a smattering of knowledge of this matter.quote :
Not quite sure what you are getting at here apart from the obvious sarcasm (which of course I am getting used to 🙂 ) but let me try to educate you a little.
The original genesis account was an edited version from pre existing histories that were inscribed probably on clay tablets.
The chapter headings and verses we see in bibles today are the work of translators of the King James Version of 1611. They are not the originals.
(there is a little bit more but I am not going to bore you with the details)
The genesis account is an edited version of 12 histories, each history concluding with the chapter and verses as follows.
Chapter 2:4, 5:1, 6:9, 10:1, 11:10, 11:27, 25:12, 25:19, 36:1, 36:4, 37:2 and the last 50:26.
Note please these are historical accounts. I am not cherry picking anything, but merely examining anything from the account that could be in accordance with known science.
So please read what I am actually writing not what you may wish it to be.quote :
Yes I do know my geology, and yes again and I do read the links I provide.
I suggest you read the USGS link properly.
First, you will not find that I used the word Pangea anywhere in my post.
Secondly the name Pangea relates to the “Continental drift theory” not plate tectonics.
Now Patrick you are showing signs of desperation here.
Neither I nor the genesis account (1:1 to 2:4) mention any geographical names.
A feature of the account is the fact that no geographical names are mentioned.
Even the sun and moon are referred to as the greater and lesser lights.
This suggests that the account was initially set down before any geographical names were invented.
Geographical names first appear in Chapter 2:8.
Also the account and I make no mention of what the land mass looked like, simply that it was all in one place, just as the modern day view is, that is all.
Are you trying to introduce a red herring in an attempt to camouflage some interesting information?
Now there are a few more interesting little nuggets but I had better wait until you cool down a bit before I enrage you again.

I forgot to respond to your last comment regarding your agreement with me.quote :
Well actually I am not exactly in agreement with you here.
The virus could not predate the cell because it is essentially a protein shell housing some bits of nucleic acid (either DNA or RNA, depending on the virus) but not because it is a parasite which of course it is.
Protein could only come from a pre existing cell process.
The cell had to have predated the protein because it contains the processes that make protein.
So if we are to have common ground, and it’s nice to have some, I would like to be clear what that ground actually is.
This is an important fact as I hope will become clear.
A specially commissioned piece of research by NASA is available online by the National Academies Press entitled
The Limits of Organic Life in Planetary Systems
Here are some extracts.
Page 60quote :
There is a lot of good and honest science being put forward here.
What is it telling us?
Firstly — There is no “plausible” route to complex biomolecules.
Secondly — An external source of free energy is needed to form these compounds.
In other words some outside agency is required.
Thirdly — Clearly in water, either thermodynamically or chemically, biomolecules whether they are nucleotides or oligonucleotides or amino acids chains, cannot form spontaneously.
Yet Darwin and many others, like Stanley Miller and Harold Urey and many others have all posited and indeed continue to try to show that life could have spontaneously originated in water.
All this in spite of science being against them.
When I have said that these hypotheses have no bases in science, even NASA agrees with me.
The cell had to predate the protein, there is no way around this in science.
Philosophically, one may wish to hypothesize chemical processes that lead up to the formation of a cell, but scientifically they are implausible.
As NASA research has confirmed, an outside agency is required.

Origin of Life.
Since no one is prepared to reveal what is their understanding of the processes that cause speciation other than simply state that, “evolution is a fact”,
I will try and describe my understanding of what the consensus opinion appears to be.
How can Life be defined?
Here is a definition
Life is a system of chemicals that possess functional information (i.e.knowledge) in their molecules and a mechanism to implement that knowledge in such a way that the system can survive and replicate itself.
My understanding of the Molecular theory of evolution
Sections of DNA store information needed to make proteins. This is functional information (knowledge) and this is what constitutes a gene.
This knowledge is passed from generation to generation by a process of replication.
Chance or random errors during replication or other causes, create the potential to make new genes.
These mutations may create new information or alter existing information.
In either case nature preserves the beneficial mutations ( i.e. the knowledge to modify or make new proteins) by the process of natural selection, while the other mutations survive only by chance.
Over millions of years changes in existing genes result in new genes and that is the way animals adapt and evolve.
The problem with this framework is that if an existing gene evolves into a new gene with a new function then the old function will be lost.
Natural selection however will not allow that to happen, for obvious reasons.
So it was hypothesised that existing genes do not evolve into new genes unless the first gene is duplicated.
This duplicate copy is now free to evolve while the first maintains its function.
This theory has since been refined by further suggesting that pieces of genes may be duplicated and then rearranged to create new genes with new functions.
This is the theory that essentially explains the origin of many genes.
Remember all these mutations are chance (random)mutations that can only be filtered by natural selection if they have function, (i.e. they produce protein.)
Natural selection cannot act on any stretch of DNA unless it has a function that has produced a protein
Also remember that the cell is presumed to be in existence for this hypothesis to even get started.
Also this process is blind and has no foresight.
So the origin of the cell is unanswered and as we are now discovering there are no natural plausible pathways to the production of complex biochemical molecules.
What does that leave us with?
August 25, 2011 at 3:14 pm #106065
I like that last post.
At least it makes clear what we can agree and disagree on.
Basically you got the gist of how genes do evolve, change multiply. I just would like to add that gene duplictaion is not the only way to create new genes. So genes can be fully acquired from another organism (but it need to have evolved there) by horizontal gene transfer, and some genes that become useless because e.g. the environment changed are not the subject of selective pressure and can evolve in interesting new ways.
Plus there are genes that affect the regulation, the expression or even the folding of the protein. All that can drastically affect survival in certain conditions.
But I digress, you seem to accept that all that is convincingly proved and that it can happen. Am I right?
So your biggest problem is not how can the information multiply and change over time, it is only it can appear in the first place. Your problem is not with evolutionper se, but with the creation of life.
In which case Genesis 1 (I checked, it is in the first chapter, and you were right there is only one version of the creation of life on the earth, the 2 different stories in genesis 1 and 2 are about the creation of man), is not massively helpful either because it just tell us that it is so because of the word of god. Hmmmm…
The science of the creation of life is much more complicated than that of the following evolution for a simple reason. Whatever the first self replicating organisms, or more likely molecules (Science’s best bet is currently self replicating RNAs with catalytic activity, as those things can be observed), they did not leave traces to be analyzed, so it is as much a game of conjectures based on the current observed outcome and what we know about the primitive atmosphere’s (and there is guesswork there) composition and conditions. A few hypothesis have been offered, but since the conditions are hard to replicate (who has a set of empty planets at the right position and a few billion years to observe the outcome? And even more importantly the funding to run the experiment? :D) it will probably stay at least very informed guesses at best.
But they are based on observation and fact. The problem with assuming a creator are multiple and honestly strong enough to make the hypothesis quite implausible. I will refer you to the very nicely written open letter of R. Dawkins to the Gov. Perry. because he writes so much better than I do:quote R. Dawkins:
In my word: If one assume that information cannot arise spontaneously, which is what you do, then we have to assume that an original agent created the self replicating information. But that leave us with the problem of the origin of this first agent. It is just like panspermia, life may not have originated on earth (makes the game of informed guesses about the condition for the origin of life even more complicated), but the process for its creation somewhere else must have followed the same general rules. It is just moving the problem without providing any new information. So pray tell me, where does the original agent come from?
This is not science, this is logic. In science when you are making an argument you have to demonstrate that it holds water. You can spend hours on the rest if your foundation is leaky, however beautifully crafted and built is the rest of the edifice, it will crash down. So will you finally answer my simple question? As long as you cannot even provide any clue, speculation or whatever beginning of information about that, all the rest is just wind. If you keep posting your long winded diatribes and ignoring that little fact, I will have to assume that there is no point in having a discussion with you. So, once again and very clearly:
Where does the original agent come from?

Thanks for your post
I have got to go out this evening so will respond first thing tomorrow morning.
August 26, 2011 at 12:18 pm #106084
May I deal with your response one at a time, as all you that have written is definitely worthy of a response.quote :
Well no, not quite.
If you will recall I have made repeated attempts to get someone to posit their understanding of what “evolution” actually is.
That ended in failure so I posited my understanding of what is generally understood and of course centred that understanding specifically around molecular evolution.
The principle behind the idea of gene duplication is to account for how a new function can arise without the loss of the old function, which natural selection (the central concept of Darwinian theory) would prevent.
Natural selection can only select from an existing function. It does not create new functions.
In other words Natural Selection can account for the demise of a species not the arrival of a species.
Therefore another “gene(s)” however arrived at would be needed and free to evolve.
The central question though is whether these theories or hypotheses can account for the arrival of new species (i.e. new body plans.)
So lets examine what the science is behind these hypotheses.
Gene duplication, does it occur?
Yes it does
http://onlinelibrary.wiley.com/doi/10.1 … 3/abstract
Spontaneous duplication of the mammalian genome occurs in approximately 1% of fertilizations. Although one or more whole genome duplications are believed to have influenced vertebrate evolution, polyploidy of contemporary mammals is generally incompatible with normal development and function of all but a few tissues.
There is of course a lot more information that highly questions that gene duplication can account for speciation and if required I will provide the evidence.
HGT is posited as another method by which natural selection would be allowed to operate.
Does it occur.
Well yes again, in bacteria and unicellular eukaryotes.
And again I can provide a lot more information as evidence, but at best these ideas are definitely questionable when it comes to explaining origin of speciation.
This is why there are so many ideas that try to explain speciation with some directly contradicting Darwinism, Evo Devo and Symbiotic theory are but two of them.quote :
Ii is not me that has a problem. It is the many scientists (not science) trying to explain these matters that have the problem.
Now I will end this post here to allow a response to this particular part and will respond to your other points shortly.
August 26, 2011 at 10:22 pm #106090
Ok lets continue, this is a long one but you have raised quite a few pointsquote :
It’s nice to see you have at least done some homework and agree with me on the number of creation accounts.
However please read the account more carefully.
1) The second is not about the creation of man, it is about the start of his history.
The creation of man (male and female) appears in the first history. Chap 1:27
You do yourself no justice when you make such careless errors in the simple matter of reading accurately.
2) Where does the account state it is the word of God ?
Your bias is blinding you to what is actually being stated.
This account claims to be a history set down by ancients. The only question that can be attributed to it is whether it is accurate. That’s all.quote :
Leslie Orgel’s posthumous essay on this subject is worthy of note.
Remember he was one of the originators of the RNA world hypothesis.
Now please read his paper of 2007 and note his conclusion of his own hypothesis which you will find here.
It is entitled
The Implausibility of Metabolic Cycles on the Prebiotic Earth
http://www.plosbiology.org/article/info … io.0060018
And here is his concluding comment
"However, solutions offered by supporters of geneticist or metabolist scenarios that are dependent on “if pigs could fly” hypothetical chemistry are unlikely to help."
The above is not the conclusion of some lone scientist because there are many.
Remember I informed you of the conclusion NASA itself had reluctantly arrived at.
There are no natural plausible pathways to the production of complex biochemical molecules.
You see science knows that pigs don’t fly.
You would do well to research your belief system properly rather than running with “pigs will fly” hypotheses and then treat them as if they constitute science.
Now we already know that water prohibits any peptide sequences from forming.
They are both chemically and thermodynamically implausible.
This is a scientific fact.
So what would be a better place to get started?
Well, instead of water how about earth.
You know those ancients were indeed quite clever chaps..
Just look at what they wrote about the first forms of life.
“And the earth began to put forth grass, vegetation bearing seed according to its kind and trees yielding fruit, the seed of which is in it according to its kind……"
So far then, this account has been shown to be correct in that originally, all the land mass was in one place.
Those ancients clearly knew something that has taken modern science quite a little while to catch up with, me thinks
Certainly contrasts with Darwin’s musings of “quiet little pond” somewhere. 🙂
Now we note that they even knew where life got started and you appear to be still struggling to catch up.
OK lets take a third
There is a biologic logic about the first forms of life being vegetation.
After all they manufacture their own food in order to survive.
The account then goes on to state that life then got going in the seas and atmosphere and then the animals of the land.
Scientifically implausible or scientifically plausible?
Remember this is just an historical account. It’s not a scientific document.
OK lets take Dawkins little open letter to Rick Perry.
I don’t know much about this Perry person other than I think he considers himself suitable to run for the presidency of the US.
However I do know a little something about this Richard Dawkins fellow.
He is the eminent scientist who hypothesized the “selfish gene concept”
That turned out to be wrong. Strike 1.
He is still stuck in his “gradual evolution” mindset.
Again we have science turning against him. Strike 2
What about his Tree of Life mindset?
Now you ought to know all about this, what with HGT and all. Have a chat with Carl Woese.et al.
So that is also turning against him — Strike 3
Was it not Mayor Rudy Giuliani who came up with the 3 strikes and you are out policy.
Of course the scientific community are a little more tolerant 🙂
A little bit of advice, if you must quote him do it on his religion not on his science.
Now this is quite a “long winded” post as you keep reminding me so I had better end it here.
I will deal with your next point tomorrow.
Trust me I will answer your question 🙂
August 30, 2011 at 12:16 pm #106122
Sorry for the delay.
As I understand it your argument is essentially this.
So long as the originator cannot be named or identified then that is evidence the originator doesn’t exist.
Therefore (according to your logic Gravity doesn’t exist, The Laws of motion do not exist and as we don’t know who invented the wheel so it doesn’t exist either etc etc.)
Now of course this is nonsense, as you well know, and we have covered this point before.
However I have noticed that you have changed your approach somewhat.
You previously wanted to know the name of the originator.(agent)
It has now changed toquote :
Look I don’t need to pray about this.
Be that as it may, lets deal with your comment on information.
We know, because science has established it, that the metabolic pathways we observe in the cell do not exist in natural law.
Natural laws that the study of science rests on, are not observed in the functional information content we observe guiding cell processes. That I assume is clear enough to you, since you have not attempted to rebut any of the information I have provided.
Therefore that guiding information can only come from an outside agency as I keep stressing.
Now you may not have realised the fact that information is non material.
The chemical molecules are material but the information they contain, that directs them in ways that are not linear and in non random ways, is not material.
Why else does the cell enlist such elaborate editing and feedback looping that we observe. Also we are now observing the tremendous redundancy that exists ensuring constancy of functional output.
All our experience tells us that this king of information comes from a mind, one that is using “ an external source of free energy” as NASA puts it.
This is the only evidence we have and all that evidence is staring at us, inconveniently it appears to some or indeed many.
So why is it so difficult to grasp such a simple concept?
There can only be one reason.
Your philosophy prevents you from doing so.
Please reflect for a moment, on your own statementquote :
Now apart from the fact that you aren’t keeping up with the latest understanding amongst scientists, you are reducing your view of science to a casino operation.
Scientists with certain philosophical needs may engage in betting, science however is not a casino.
This type of wishful speculation stems from a philosophical need.
It has nothing to do with science and deep down I suspect you know it.
( Freeman Dyson sums it up nicely in a conclusion comment to his own speculative scenario on origins.
“ The question is whether any of that makes sense. I think it does, but like all models, its going to be short-lived and soon replaced by something better.”)
One thing we are agreed upon though.
Logic is not science. There maybe logic in studying science but in itself it is not science.
Philosophy, parading as science however cleverly it may be dressed up, is also not science.
At least creationists, bizarre though some of their statements may be, wear their philosophy/religion on their sleeves.
You though, are trying to camouflage yours under the guise of science. That is not a very stable foundation.
Now there are invariably fundamentalist diehards who despite all the evidence to the contrary will continue to stick to an idea, no matter what.
I sincerely hope you are not one of those, but that has to be your decision.
In the meantime however I will continue to present information in the hope of course you don’t bar me from this forum. 🙂
Craig Venter and George Church recently had a discussion regarding the ribosome which is very revealing.
I will copy part of the transcript in my next post, as this has gone on long enough. 🙂
August 30, 2011 at 12:51 pm #106124quote scottie:
I have probably skip this one. Which natural laws are you talking about?
August 31, 2011 at 2:47 am #106141
Now Scottie, my simple question is one of logic, not science, not naming not nothing, simple logic. I will detail it one more time for your understanding:
1- Complexity, such as observed in life, cannot arise spontaneously
2- Ergo matter needs guidance by a complex entity to organize it self in living beings
So what guides the matter? And how did it appear without guidance, as it would launch us in a recursive loop?
August 31, 2011 at 12:22 pm #106145
Nucleic-acid-peptide micro-molecular technology – a database of DNA through RNA intermediaries is implemented by the polypeptide interface. But this is an automated production system. A user who is? And this is an older subject – glyco-lipid membrane. Once upon a time, a few billion years ago, some engineers of a great civilization glyco-lipidoides created this nucleic acid-peptide technology and armed with it, settled by a million ships in all parts of the visible universe. But what do our evolutionists? And they are the origin and evolution of life on self-replicators – RNA! Wow! So you can keep your computer from the origin of a computer mouse! Yes, the computer system, of course at the last regular duplication mice formed a small detail, like user … 😯

JackBean » Tue Aug 30, 2011 12:51 pmquote :
The laws of Physics, Chemistry, Thermodynamics.
These natural laws are not left unguided in cell processes. They are guided by the functional information contained in the cell.
That information is not internally sourced but, as for example, NASA has concluded can only be from an outside source.
As I have already stated in my last post.
It did not appear without guidance.
All our experience tells us that this kind of guiding information comes from a mind.
Is there any other logic we have experience to go on?
If so please inform.
As I understand it, you have a view that life was planted here on earth by an extra-terrestrial lifeform.
Is that correct?
September 5, 2011 at 7:12 am #106177
I think the concept "extra-terrestrial" for life is not correct. Life is life. It is the same painful geo-anthropo-centrism. Intelligent life, armed with a nucleic-polypeptide technology could in a few billion years to spread widely in the universe, and here we have one of the planetary population. It is strange that you do not think this is correct!
Another interesting question. The above is obvious, but the crowd of smart people at NASA and elsewhere raise the question only about panspermia microorganisms! Why not reasonable landings? It’s that – a taboo? I wonder who the customer? Ah yes, the theory of evolution as something is lost … And creationism, too, seemed suddenly melts away … Wow!
September 5, 2011 at 8:29 am #106178
There is also the question of why intelligent life is usually unwise? But it is not difficult:
Collapse of civilizations – the regression of creative thinking
It is well known that in the living world all on demand and trains – is evolving and what does not on demand and no trains – regresses.
This refers to the organs and tissues of our organism to thinking skills, communication, food and much more, but also social institutions, and large industries. And more broadly – to the development of species and entire ecological systems. "Claim" in different cases is a demand, "social order", "selection pressure" and so on. If this law of nature to apply the theory to our ability to think creatively, the result a sudden a logical conclusion, which is the very our "starting point".
Sense reasoning is as follows:
Creative intelligence to develop a species until it is demanded. With it, created an elaborate set of global technology standards and stereotypes in all spheres of public life. But then, after reaching a "global harmony" and a "welfare society" creative intelligence is no longer needed, subject to negative selection pressure and begins to regress.
30-50 thousand years happy hypothetical "world empire" (or "Democracy") becomes a world of "ants" in the minds narrowly stereotypical type of mind, where a return to the creative phase is almost impossible.
A thousand years later, 200-300 changes in genetically fixed and this species generally losing the creative intelligence, and the "purposeful activity" in this society is no different from the cooperative activity of the same social insects. This is not the mind, and his remains – a relic. Relic Paleo-civilization reasonable.
Armed with such a logical premise, it is possible to take a fresh look at our world as something that it has featured such "relics of the Mind," left over from long ago emerged and faded manifestation of "creative intelligence."
This is the same social insects, provided such relics of two integers: public-Hymenoptera (wasps, bees, ants), which became public, according to various sources, from some point between 50 and 100 million years ago (an ancestor – a giant wasp) and
– Termites, which have left their public relic from a certain point in time from 120 to 200 million years ago (an ancestor – a giant cockroach).
Can claim to be a "relic of reasonableness" and
– Multicellularity our organisms (there was about a half billion years ago, the creator – Vendian biont large aerobic unicellular ameboid, who built a very complex civilized society – a multicellular organism Myxomycetes).
Some terrestrial civilization can not leave behind a "relic" – coelenterates, sponges (archeocyathids), marine polychaete (trilobites), rakoskorpions, siphonophores, salps, cephalopods, and pikaias.
Well, the question of how to achieve the welfare, thus, is a question of how to kill a civilization. 😥
September 5, 2011 at 8:55 am #106179
Can you tell, how exactly the metabolic processes are against the natural laws? Because I’m pretty sure they are not.

September 11, 2011 at 10:43 pm #106297
Sorry for delay in responding. I have been away for a few days.quote :
I think you misunderstand what I am saying.
Let me try and clarify.
The molecules involved in metabolic processes, without a guiding outside source of energy will follow the natural laws and disintegrate down to their elemental natural states.
I have approached this subject before but I feel it is now important to revisit it again.
Lets take the question as to what happens at death?
In other words what is the difference between, say, a living dog and a dead one?
At the moment of death, all the processes we have studied in biology cease and the dog begins to disintegrate.
However that disintegrating corpse is still subject to the same laws of physics and chemistry as the live dog was, so what was keeping the live dog living?
At the moment of death all the biochemical molecules in body are the same as when it was alive. The same functional information in the molecules remains, yet function has ceased.
Now ask yourself what kind of logic are we appealing to which suggests, that by assembling all the molecules together (assuming we are able to of course) into the form of a dog, we will create a dog that lives, or indeed any form of living organism.
Doesn’t all our experience, data and intuitive understanding tell us that life is something apart from mere chemical molecules?
Life is what keeps the chemical molecules that make up our bodies from following the natural laws that send these molecules back to their constituent parts. When life is removed these molecules begin reverting back to what they were originally.
I hope that explains my point more clearly.
btw I am not arguing for the ID community. There are some fundamental difficulties I have with their line of argumentation.
I will be happy to explain in more detail if called upon.
Sorry but I am having great difficulty in understanding your posts.
It maybe a language problem.
September 12, 2011 at 5:54 pm #106310quote chilipanda:
What about a theory that suggests there were no origins of life in this natural Universe because it connects Cosmological Evolution to Biological Evolution? This theory is the result of comparative anatomy between the first cell system and the last non-living system, which built a model of LUCA (the last Universal Common Ancestor), a kind of building blocks of astronomic systems, the lost link between the state the world about 4 billion years ago and the first nucleotide at Earth. The theory suggests the DNA as a universal template, called The Matrix/DNA. So, it is not panspermia, only suggesting that there was a hidden variable ( the matrix ) at the primordial soup.
Ok, I am the author of this theory which has cost to me about 30 years of hard work. As an agnostic I don’t believe in this theory but the amount of evidences and right predictions are becoming astonishing and I am testing the models. I need ideas for testing/discussing and your topic – as I am following it – is very interesting and helpful. I should be grateful if you permit to participate in this debate. At least, I can suggest faults and gaps on the existents theories that nobody else has thought about. I can do it? Cheers…
September 12, 2011 at 10:31 pm #106313quote believer:
There is a set of natural laws and mechanisms. If you know them and follow biological evolution in the reverse way towards biological systems origins, you will be no “left to speculations”.
Feel free for asking or pointing out when you think there are gaps.
But, then, you will arrive at the state of the world before life’s origins, the world that created life. If you apply the same set of laws for calculating that state of the world you will get a surprising cosmological model, where Astros exists under life’s cycles and performing perfect closed systems. The blueprint of this model is a building block, identical to a nucleotide, the fundamental unit of information in the DNA. So, there was no origin of life at Earth, because Earth, itself, belongs to a system that is half-living.
So, the right calculations using only natural laws and mechanisms you discovered that there is a link between biological evolution and the past cosmological evolution: the DNA template.
Continuing going deep to the past, with those laws, you will arrive to the primordial nebula of atoms systems. But, then, you will have a more complex model of atoms: they have the principles of life’s properties.
Go deepest, before the atom nebulae, and you will meet with empty vortexes. But, you will see that those vortexes have the laws, the mechanisms and all life’s properties.
Now you are going to before the Big Bang, leaving this Universe and believing that those vortexes are bits-information, like genes, coming from a natural system, ex-machine. That could be your God. To me, it means merely more research work to do…

As promised in a previous post, a transcript of an interesting conversationquote :
You will find more information on the scientists including video clips from this event.
The video clip of Robert Shapiro is quite interesting.
I would recommend spending some time reading and viewing this.
Here is part of the transcript of the Event.
Discussion between Venter, Church and Shapiro.
Page 76quote :
Notice how both Church and Venter agree that the ribosome has no precursor, in fact Church recommends that the ribosome is the candidate for the ID community to concentrate on as an example of irreducible complexity.
So the evidence is quite clear to these scientists, but note Shapiro’s interjectionquote :
Here you have an obvious example of a renowned scientist whose thinking is guided by his philosophical view rather than by evidence.

There clearly is a problem in translating from Russian and it does make understanding your posts a little difficult. However you must be commended for trying.
I have spent some time in trying to understand your position, so let me try and respond to your view.
As I am beginning to understand it, you use the expressionquote :
In other words it seems to me that you appear believe that a technology has been developed in the past whereby peptide chains could be produced, thereby providing the ability to make cellular life.
This technology has been transferred to the earth and that accounts for our present condition.
I think you agree that this view is highly speculative, but more than that I believe you are making the same basic mistake that evolutionary theory an indeed ID theory make, that is, the appearance of life has been through a bottom up process.
In other words you start with basic building blocks ( pre-biotic and then biotic) and then build up the whole organism, this essentially summarises the evolutionary view.
The ID view ( as I understand it) has a similar perspective in that the designer has built up the organism in a Lego-like assembly way.
However this does not reflect what we observe in reality.
Let me try and explain with an example.
We tend to see the cytoskeleton portrayed as a fixed structure,
But that is simply incorrectquote :
Cell Mechanics and the Cytoskeleton – Nature 463 Jan 28 2010 485-492)
The cell is typically about 80% water and when examined we note that the main activity is a pattern of flows. What we see are fixed structures that actually are part of these flows.
Craig Holdrege in his book “ The dynamic Heart and Circulation” describes the development of the heart this way
We have been educated to see the living organism as an assembly of individual parts,for example like a watch that is put together in a certain way.
However in a living organism, (as one writer puts it)quote :
Both the evolutionary and ID views have this common foundation. They have a bottom up perspective of living organisms, when in fact the reverse is the case.
It is the whole that determines the parts. This whole is determined from the moment the two gamete cells join to form the Zygote.
It is this wholeness that scientists have not been able to come to terms with, and the result has been a fruitless search for some understanding as to how these parts could have come together to form the whole we see and indeed are.
Chemical molecules do not come together to form life.
Even cutting edge biologists such a Craig Venter and George Church are beginning to recognise this fact.
(The little transcript of their conversation at the Edge event that I had in my last post reveals this)
They are only one step removed from recognising that life uses chemical molecules to persist. When life ends these molecules revert back to their constituent parts.
We know of no instance where life has come from any source other than another life.
To try and show that it can and indeed has is no different than looking for fairies at the bottom of some garden.
September 15, 2011 at 1:25 pm #106353
No, Venter says, that the precursor is from RNA world, but since we don’t have no such ribosomes nowadays (w/o proteins), we cannot reduce the number of proteins to less than 53.
September 15, 2011 at 1:34 pm #106354quote scottie:
Ahh, you mean this…
The molecules are still the same, they are just not regulated. Even the cells do not die immediately after death, but they survive a little, although they are not synchronized anymore and of course, the shortage of supply causes their death later. This was discussed in another topic recently.quote scottie:
Please, go on.
September 16, 2011 at 11:50 am #106368
Thank you! 😀
The hypothesis is that the cell membrane – this is a direct descendant of the brilliant engineers who have several billion years ago created "Nucleic-acid-peptide micro-molecular technology". That’s membrane and is the carrier of "consciousness" – what we call ‘I’. Everything else – equipment.
You can say so, that in every cell membrane formed a kind of cellular "self", which is the "active model of the world in an electromagnetic field of the membrane."
I must add that this hypothesis is very useful in molecular biology, because it creates a theoretical model of cell entity which manages all the cellular technologies. A lot gets new meaning clear! At least, now we need to look for those instructions that guided this subject!
September 16, 2011 at 3:09 pm #106369
Thanks for your response.
May I deal with your points in turn for fear my post will get too long, something for which in the past I plead guilty. 🙂quote :
Firstly please note what he previously said about the ribosomequote :
Also what Venter actually then said was thisquote :
The RNA world is a speculative scenario that many are clinging to in order to have some hope of progress. However even Venter knows that is a speculative hope. He probably was not aware at that time of the NASA report (I have referred to it previously) which stated quite clearly that there are no plausible hypothesis for routes to complex biochemical molecules, either chemically or thermodynamically.
So probably not even being aware of the NASA conclusion at that time he remained in the speculative world of RNA
Now if you wish to remain there as well, then that’s OK it’s your choice, but please, remember that science is not backing you up.
Now on the question of organism death you respondedquote :
You are right we have discussed this before, and forgive me when I state that I feel you may not have quite grasped the point I was making.
At the moment just prior to death all the biochemical molecules in the dog are still functioning and intact.
At the very moment of death they are still there, however as you rightly point out the regulatory mechanisms cease and the molecules begin to disintegrate.
In other words, the natural laws of physics, chemistry and thermodynamics continue operating but without the guiding regulation that has now been removed, and the result is degeneration, down to their constituent parts.
Therefore the natural course that natural laws take, breakdown biochemical molecules.
Since that is the case how can those same laws naturally guide the building of cellular life let alone the whole organisms
They have to be guided down the different regulated pathways if they are to succeed.
So whatever life is, it is certainly not a constituent part of physics or chemistry.
That is why a naturalist view of the origin of life is scientifically untenable.
That is also why NASA has been forced to draw the conclusion it has.
If any organisation needed a natural explanation to life’s origin it is they.Just think of all the funding they would receive if they could. There is every incentive for them to prove that they have conquered the problem of Abiogenesis, and if they were able to then I will let you speculate on the news headlines!!
One further point to note.
Nobody has been able to describe what life actually is.
There are many who have tried to define it in one way or another, but there is no consensus even on this basic point.
One rather cute tribal description is :-
“Anything that is capable of Darwinian evolution”. 🙂
I will deal with the ID situation very shortly in the next post.
September 16, 2011 at 3:51 pm #106371
Here are problems I have with Intelligent Design theorists.
This is what they have to say.
There appears to be a contradiction in the above statement.
A fundamental doctrine of Darwinism is the principle of common decent/ancestry, and yet some adherents of ID ( Michael Behe for example) endorses this principle of common ancestry.
If there is common ancestry then there has to be a mechanism that engenders this process. I have not seen that explained anywhere. Darwin explained his mechanism.
Also, by way of an example, why would a designer tie a human being to an ape through common ancestry.?
Why not make each separately?
It seems to me that some of the ID community are facing both ways. I have tried to find an explanation as to how this is not a contradiction but have been unable to as yet. Maybe some one will be able to enlighten me.
However there is a more fundamental problem in which ID is explained.
Perhaps I could illustrate it this way.
If I am to design a house, I don’t start with designing certain aspects of it say, the kitchen sink, then the bathroom mirror or bedrooms etc and then try and fit them all together to provide an overall framework.
In other words I don’t start from the bottom and work upwards.
This is how evolutionary theory is explained. (i.e. a bottom up approach)
Design however implies purpose. Therefore it is a top down action.
So, to try and explain design as ID proponents do in finding structures within an organism that are, for example irreducibly complex and then stating that this is evidence of Intelligent design is not sufficient.
A living organism is more than the sum of all it parts.
Also they appear to present a mechanistic view of organisms, a sort of sum total of biological machines.
The very icon of the ID community is presented as an outboard motor. (the bacterial flagellum).
When something is designed, there is always a purpose to the design.
The various parts that go into that design always grow out of that purpose.
Now I don’t see the ID community addressing this anywhere in their literature. In fact they appear to concentrate on simply refuting neo Darwinism.
Actually there is nothing wrong in presenting evidence that corrects a wrong idea.
I myself can be successfully accused of that.
Certainly the work they do is very informative and I have learned a lot from them as indeed I have from the evolutionary community.
However there is no apparent attempt to replace that idea (neo Darwinism) with another that demonstrates purpose.
They are shying away from the obvious implications of what design means.
September 21, 2011 at 7:08 pm #106405
Continuing on with the problem ID has not addressed.
As I stated in my last post.quote :
Design is always the product of a purpose the Designer has in mind.
If, as do the ID community, argue for Intelligent design, then they must reveal their understanding of the purpose of the design.
As I see matters this is very important because they are against a theory that posits randomness without purpose and they are arguing the exact opposite.
Now the evolutionists cite as their frame of reference Darwin’s Origin of Species (albeit with modifications, but with the central tenet intact).
That is their narrative.
Why can’t (or wont) the ID adherents narrate their own frame of reference?
They need to bite the bullet on this issue.
If they believe in the veracity of the scientific method, as indeed I do, then they should simply follow that method. Here is a good description of the scientific method.
http://teacher.pas.rochester.edu/phy_la … ndixe.html
As far as I am aware this forum has presented a few hypothesis
(1) There is of course the Darwinian narrative (with all it’s epicycles)
(2) Then there is the Creation narrative (with all it’s misunderstandings and bias read into the genesis account)
(3) Then there is Leopol’s Nucleic-acid-peptide molecular technology.
(4) Then there is also the genesis historical account itself (without any bias attachment)
(5) Finally there is Intelligent Design, without a purposeful narrative.
My question is simple.
Is there another narrative and if not,
Which of these accounts is most consistent with the scientific method?
September 23, 2011 at 1:57 pm #106425
I can’t understand how works the thoughts of all of you that search the answers for life’s existence. If you could explain to me, should be very grateful.
Let’s go start with this:
There are enough evidences pointing to a common ancestral. The debate now between evolutionists and iD is:
– Is evolution an unpredictable and purposeless process that "has no discernable direction or goal, including survival of a species; or
– Evolution is a process under design and purpose?
Ok. How my thoughts have worked? I am at the middle of evolution process. I am inside the process. So, remembering the Gödel’s theorem, it is impossible to whom is inside a system, to know the thru about that system. I never will know the thru about evolution. No way. First of all, the evolution we are watching in the whole Universe, can be merely phases of a universal process of reproduction. Then, nobody can say scientifically that there is evolution.
There is a natural process of evolution that is outside of me, I am bigger than it, and I can watch it, fully. And this sample of evolution obeys the evidences for evolution: it is triggered by a common ancestral.
What is it?
The origins and development of a human body. Everything is equal to Darwinian mechanism of evolution: natural selection, variation, inheritance, common ancestral.
The common ancestral is a genome. The body in formation takes several different shapes (see Haeckel’s recapitulation Theory). The environment plus the forces inside the fetus sets the selection and fix shapes in the evolutionary tree.
The genome is the common ancestry. But it came from the parents; they designed the purpose of that evolution towards a final determined forma: the human shape. This evolution process I am seeing has no purpose of a final design in the image of the common ancestor, but an image beyond it.
At this point you are saying: “Wait! You can’t make this comparison. Everything is different…”
And I will ask: “I said that the final meaning is the same, since that the basic postulates are the same. What is different?”
Maybe you will not answer this question or at least will say: Louis this is such an absurd that I will not waste my time with it.
And I will comment: “My friend, the modern human kind are living in a such artificial world, with the brain hard-wired by too many scientific fantasies, that it cannot think anymore as a natural being. Why not apply Ockham’s Razor over this question? If we have a real and natural fact under ours eyes, why appellate to imaginary constructions?
I am not saying that my method suggests the common ancestor was made by an intelligent designer, neither that there is a God. My method suggests that the common ancestor was not a microscope initial life form. It was the astronomic system surrounding us, but, then, I have a theoretical cosmological model that fits as the common ancestor, different form the theoretical cosmological model that you have seen.
Why not trying to think out of the box, pointing out what is different between these two processes of evolution?
September 25, 2011 at 11:37 pm #106441
Thanks for your response.
I am a bit tied up at the moment but will respond as best as I can tomorrow.
I will make one observation on your comment below.quote :
The problem with your statement is that the ID proponents argue that common ancestry is also evidence of a common designer.
In other words the evidence that can be argued to suggest common ancestry also could support the common designer view.
I however do not share the view that some ID proponents take on this matter for one simple reason. The evidence from science does not support it.
I will summarise the evidence more fully tomorrow.
September 26, 2011 at 9:40 am #106443
I adhere to the hypothesis that the engineering design occurred during the rare periods when the developed technological civilizations. This has happened very rarely. But for a very long interim periods ran the Darwin’s Natural Selection, as well as Dawkins’s His Majesty the Selfish Gene! At the same time created by the engineering design technologies were degenerative effects of natural selection. As a result of species to varying degrees, lose universalism, but due to hypertrophy of various technological relics specialize in different biological niches. It is Macro-devolution!
Now – the arguments. Nucleic-acid-peptide molecular technology we have already considered. And now – eyes.
With all the great variety of eye, inducers that control tab in the ontogeny of the eye are the same for all studied taxa, including vertebrates and jellyfish. Moreover, the settlement and the time of appearance of the first sample of the inductor – Vendian.
These eyes have a lens with a jellyfish: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2825319/
And also Turbellaria: http://ru.wikipedia.org/wiki/Ресничные_черви
In polychaetes: http://www.liveinternet.ru/showjournal. … id=1022068
Further. Human embryo at an early stage has gills, caudal fin … But he can not use them. This is because genetic technology support was lost when the larva was in the placenta. Or in the egg. Macro-devolution is irreversible! But now, the frogs have a larva with gills and tail fin! They are versatile us. A Turbellaria, some species of which contemporaries and now have eyes with lenses, the brain is orthogonal to type, the organ of equilibrium, etc., they are active predators! – Some Turbellaria are also free-living Müller’s larva! Hence, their ancestors – in Vendian! They still have more versatile! Give Turbellaria such a trifle as a skeleton – and it is no easier to us.
So, Turbellaria in Vendian – a super-versatile creature. And before Turbellaria? Myxomycetes! According to the logic – even more versatile! ..

There is a backdrop revealed by science that should not be ignored.
It is therefore important to nail down a few of these scientific facts that relate to biology.
This helps recognise any philosophical statements that may be presented as fact.
The smallest living organism (species) is a single cell bacteria or archaea. Nothing smaller than this cell is considered to be living. The constituent parts of the cell if removed from it are inert. (DNA, RNA, Proteins etc are all inert when outside the cell.)
http://publications.nigms.nih.gov/insid … eface.html
So what does this mean?
Simply that any discussion on the origin of species is by definition a discussion about the origin of life itself.
There are no plausible biochemical pathways to the origin of complex biochemical molecules.
I have already provided sufficient scientific references to this effect.
See my post of by scottie » Fri Aug 19, 2011 12:31 pm
Any hypothesis has to account for this fact.
Fact 3 on the Origin of the Genetic Code
There is no natural explanation for the origin of the code, even in principle.
Koonin et al concludes this way.quote :
Again unless any hypothesis deals with this fundamental question, all else is simply philosophy.
Life is only known to come from another life. This fact has been known and indeed proved since Darwin’s day
Evolution is a historical narrative based on the Darwinian principle
The National Center for Biotechnology Information (NCBI) has an online book entitled
Molecular Cell Biology. 4th edition.
Lodish H, Berk A, Zipursky SL, et al. 2000
It is an excellent reference point in understanding cell biology functions.
This is how it describes the subject of evolution.quote :
Ernst Mayr (the one of the founding fathers of the Modern Synthesis) in his 1999 Crafoord pride lecture confirms his view that this is so.quote :
http://www.biologie.uni-hamburg.de/b-on … luence.htm
So with these facts in mind how do the different views previously listed stand the test of the scientific method?
Since we are in the area of an historical narrative, the acid test for any hypothesis must be whether science supports the parts of the narrative that can be tested scientifically.
My question to you and others would be a simple one.
Does your idea have the backing of science?
If not it is simply a philosophical view.
That is not a problem as there are many philosophies around. It only becomes a problem when it is presented as a scientific fact.
So which narrative is the most scientifically plausible?
I posit that the Genesis narrative (without the philosophical/religious bells and whistles that creationists attach to it) is the most scientifically plausible one.
I have already put out some evidence but there is more.
September 26, 2011 at 1:53 pm #106446
"The smallest living organism (species) is a single cell bacteria or archaea. Nothing smaller than this cell is considered to be living. The constituent parts of the cell if removed from it are inert. (DNA, RNA, Proteins etc are all inert when outside the cell.)
http://publications.nigms.nih.gov/insid … eface.html"
– This is a clear evidence that about three billion years ago, life came to Earth from elsewhere in the universe. And degraded by the laws of Devolution! So there were bacteria. And about one billion years ago, has brought back here the settlers, but the degradation was delayed … It is still going on! 😀

“The problem with your statement is that the ID proponents argue that common ancestry is also evidence of a common designer. .. I however do not share the view that some ID proponents take on this matter for one simple reason. The evidence from science does not support it.”
And before it you said: “ I’m writing a paper on the origin of life, and I need some suggestions about which theories to write about.”
Ok. I think you will make a critical analyze of theories. Then, you need pay attemption about the meanings of nouns and words in each theory. The word “design” is full of problems.
You said: “Design is always the product of a purpose the Designer has in mind.”
And Wikipedia says: “ No generally-accepted definition of “design” exists, and the term has different connotations in different fields…
More formally, design has been defined as follows.
(noun) a specification of an object, manifested by an agent, intended to accomplish goals, in a particular environment, using a set of primitive components, satisfying a set of requirements, subject to constraints;…”
Now I ask you:
– “Why “genome” is not a designer? Considering the definition above?
I think that genome fill up every requirement cited in Wikipedia for being a designer. Wikipedia does not say that designer has something in mind , like you said, so, designer could be not something with mind. If you think that genome does not fill one requirement above, tell me.
But, why I am talking about genome?
The scientific evidences point out that all living things are made through genome. Is it wrong? The theory of abiogenesis says that the “first living being was made by the unanimated world”
So ,we have a contradiction between scientific evidences and abiogenesis theory. Is it wrong?
You said that is writing a paper about theories of origins of life. You don’t said “only known theories and theories that makes sense for you”
Then, there is Matrix/DNA Theory, unknown, that yet does not make sense because it is too much complex and different.
But , for instance, Matrix/DNA has no contradiction with scientific evidences. The problem of genome and the first living being is solved: the first cell system was made in a long process of million or billion years from the decay of a half-mechanical/half biological system that transmitted a half-mechanical/half biological genome, which shape ,constitution and functioning is suggested through a model.
The non agreement between ID and Matrix/DNA is not about the word “design”, but about the word “intelligent”. The designer and design in Matrix/DNA were not intelligent.
September 27, 2011 at 10:08 pm #106467
Thanks by the link. But… don’t forget that the constituents party of any organism or non-living system are inert alone. The liver, the heart, the planet Earth out of solar system… etc. Separating the parts of any system is not the same of reducing the evolutionary history, or the origin, of a system. We have a problem here.quote :
Sorry, I can’t understand your statement. The problem is again about the meaning of words. What is “origins”?
Word English Dictionary: Origin – 1 – – A primary source; derivation 2 – the beginning of something; first stage or part( often plural ) ancestry or parentage; birth; extraction
Then, I think, species are products of transformation, every living specie came from other living specie. In abiogenesis theory, the first cell system – aka first living being – did not came from transformation of another living system. So, I don’t think that discussion about origin of species is the same about origin of life.
I think there is no “primary source” or “first stage “ in this Universe. I think that every evolutionist and atheist should fight this word “origins” because it commonly means that something happens coming from outside the normal natural flow of cause and effect. This word is responsible for people searching something supernatural for explaining the existence of life, the beginning of religions. But, it is the cause that some rationalists also are believing in the arisen of life by chance. The words origins and life are wrong concepts.
The Matrix/DNA theory has solved this problem:
It says that there was no origin of life, as the beginning of something. Every life’s properties can be find on the last most evolved system before the first cell system (as shown in the “theoretical cosmological model”. If the models are right , at Earth surface there was origins of biological system, not life. Here, living things are products of transformation also, like species. My conclusion: You are right saying that the existence of species is related to existence of life, but, then, the theory of abiogenesis is wrong.
September 27, 2011 at 10:59 pm #106468quote LeoPol:
Congratulations. I also think “that “Devolution” is a good explanation for mystery of life.
Indeed, “life” appeared inside a system and was produced by this system that works like a watch, the Newtonian watch. But, the first living being did not work perfect like a watch, and our human body is far away from working perfect. So, only devolution explains the passage from our stellar system to the first cell system. In Matrix/DNA Theory I found a possible hypothesis for explaining this “devolutionary step”.
LUCA, the Last Universal Common Ancestor, was not a microscope half-living thing existing at earth surface; LUCA is the building block of astronomical systems. This is where life came from. LUCA, as shown in my models, is a perfect closed system, like the Newtonian watch. But it was attacked by entropy ( what you cal laws of degradation) and reproduced with mutations here, because here we have the liquid state of matter, then, organic chemistry. But, LUCA was a closed door to evolution and biological systems are opened door, then, macro-evolution came back again, going through a different pathway.
I think that we, both, are in the right way, with the idea of degradation. You are thinking out of the box, and this is good, you can find something new. Now, let’s go testing our theoretical models…
September 28, 2011 at 2:12 pm #106477
I was simply stating that ID proponents argue that way. You do not share that view.
You say that science supports your view, they say it supports their view also.
Fight it out among yourselves, it has nothing to do with me.quote :
May I suggest you read what I have said and not attribute statements to me I have not made.
I am not writing any paper nor have I requested any suggestions.quote :
I find the wikipedia defination of design quite adequate.

September 28, 2011 at 2:35 pm #106478
In the beginning …
So begins the account in Genesis.( I will return to this later)
There is also another “In the beginning..” narrative
So goes the account in EARTH SCIENCE The Story of O2 Richard A. Kerr June 2005quote :
What does chemistry tell us?
We have rocks, made up of granite. Granite consists of different amounts of Quartz (SiO2) Feldspar of which there are three kinds (KAlSi2O2, CaAlSi2O2, and NaAl2Si2O2), and Mica (every Mica molecule contains 12 Oxygen atoms (O2).
Limestone and Marble contain copious amounts of oxygen atoms as well.
So there is plenty of oxygen atoms in rocks.
Water contains oxygen (H2O)
Now stellar evolution tells us that accretion was the process that formed the Galaxies Stars and planets. The process consists of the collision of microscopic dust (the elements) and then sticking together. Let’s assume this is correct.
So the hypothesis is that all these, rich in Oxygen compounds, formed the rocks and water but without a remainder O2 for the atmosphere.
What is the physics or chemistry that can confirm this? There is none.
So why is it so emphatically stated that the early earth had no oxygen?
Is there a reason?
Why yes but it’s not a scientific one.
Oxygen cannot be in the atmosphere because if it were amino acids for instance could not form. Therefore no peptide chains. If there were none of these molecules then we don’t have proteins, therefore no robosomes etc etc.
In other words life could not begin. (the other assumption of course, is that life is simply a coming together of biological molecules in a certain way.)
So an atmosphere devoid of oxygen has to be a given, in order for life to get
There is no science behind this concept of no initial oxygen in the atmosphere, just speculation because of a philosophy. May I repeat.
This “given” is a philosophical view and has nothing to do with science.
Of course this “given” piles on even more philosophy.
For the account then goes on. “.. and life arose from nonlife”. ( just like that!!! as a famous comedian would announce when comically doing his magic tricks)
However, there is more to this tale, because today the atmosphere contains about 21% oxygen.
If there was no oxygen to begin with where then did all the oxygen come from?
September 29, 2011 at 7:02 am #106488
"In the satellite (Europe) is present thin atmosphere composed mainly of oxygen."
– And where there is oxygenation? It is also possible on Earth as it formed, as on Europe:
"The limited surface of the atmosphere is formed by radiolysis (the decomposition of molecules by radiation) . Solar ultraviolet radiation and charged particles (ions and electrons) from the face of Jupiter’s magnetosphere with the icy surface of Europa, splitting water into its components – hydrogen and oxygen. These chemical components are adsorbed and then "sprayed" into the atmosphere. Further components under the influence of the same radiation leaving the surface, and the balance of these two processes form the atmosphere . Molecular oxygen – the most dense component of the atmosphere, because it has a long period of life after return to the surface it does not settle (frozen), a molecule of water or hydrogen peroxide, but, rather, again knocked out by radiation from the surface. Molecular hydrogen is never settles on the surface, leaving it as it is light enough and at such a low gravity disappears in space  . "
September 29, 2011 at 1:05 pm #106492
Thanks Leopol, however, how does this apply to earth?
Without any more boring details of chemistry, the current consensus is that photosynthesis, initially from cyanobacteria produced the oxygen.
Now it takes one CO2 molecule (Carbon Dioxide) to produce one carbon atom and one O2 (oxygen gas) molecule.
So if there is 21% oxygen in the atmosphere now then there must have been 21% Carbon dioxide in the early earth atmosphere.
The current carbon dioxide concentration in the atmosphere is 388.5 parts per million which 0.0388%.
It has been calculated that prior to the industrial revolution, around 1750 CE, the atmospheric concentration was 280 parts per million, ie 0.0337%.
So the rise in CO2 concentration over this period amounts to 0.0051% and this rise in concentration is causing immense concern by many Climatologists, over it’s effect to life on this planet.
What effect therefore would an atmosphere containing 21% CO2 have on life, let alone getting it started.
The planet Venus has an atmosphere rich in CO2. Go here to examine it’s effects.
http://eesc.columbia.edu/courses/ees/cl … earth.html
Here is what it saysquote :
So is all this hype about an early earth atmosphere being devoid of oxygen really based on science, or are these musings ( I am trying to be polite here) simply the result of a pre conceived philosophy of abiogenesis.
The conditions that actually would destroy life are the same conditions that got life started. Does that really make any sense?
When life began the atmosphere of the earth was essentially no different than it is today.
Is this view scientifically plausible or implausible?
September 29, 2011 at 8:53 pm #106495
September 30, 2011 at 7:09 am #106499
Initially, the Earth as a planet and all, had a higher hydrogen atmosphere with small amounts of oxygen, nitrogen, carbon. Then there was the dissipation of solar wind hydrogen. Oxygen, nitrogen and carbon remained, and the hydrogen is moved farther – to the giant planets, which gradually adsorbed. Venus has an obvious deficiency of hydrogen, so there is nothing to do water ocean! But on Jupiter’s moon – Europe – more water than all the oceans of the Earth!

Your speciality appears to be random ramblings.
My advice would be to stick to what your good at, not that you have to follow it.
However if you do then less ignorance of science would be displayed.
I don’t necessarily disagree with you, as you seem to be making the same point that the lecture I referred to makes.
The lecture concludes with this point.quote :
My point is that questions 2 and 3 that relate to the earth, are not being adequately addressed by evolutionary theorists.
Accretion theory that you and the lecture clearly are referring cannot answer these questions, therefore the answer must lay elsewhere.
The view that photosynthesis (mainly from cyanobacteria) was the answer lacks scientific credibility simply because the amount of CO2 that would have been required to generate the oxygen we have in the atmosphere would have prevented life from even getting started. That then raises the question as to how the cyanobacteria even got started?
There is also another problem with this idea of photosynthesis.
Recall the increase in concentration of 0.0051% in CO2 since about 1750.
This is telling us that all the photosynthesis currently occurring today has not been able to absorb just this small percentage of CO2.
How much vegetation can we imagine would have been required to absorb all the 21% CO2?
This whole idea is fundamentally flawed.
All this goes to buttress my argument that an outside agency was involved.
That is why the genesis narrative (without all the bells and whistles that creationists attach to it) makes sense.
There are none of these chicken and egg situations we continually find in materialist explanations.

Well water – hydrogen and oxygen, and, two moles of hydrogen per mole of oxygen. With Venus hydrogen dissipated due to the solar wind, so the oxygen contacted with carbon. The result was the CO2 and CO.
The theory of accretion, I do not like. I believe that all the planets, stars, the so-called "Main Sequence" – were released in the form of fragments from the end sleeves Central galaxy’s hyper-astroid. It’s such a huge Laplace-black-star in the center of galaxy, weight – how many millions of solar masses. From two opposite-facing spindle-shaped elevations on the equator of the object under the influence of centrifugal forces are constantly torn plume material, which is fragmented into pieces of various sizes, with the Coriolis force, give them the time of rotation. Since are formed spiral arms of galaxy.

Oxygen was first associated with the whole hydrogen due to an excess of hydrogen. But after the dissipation of most of the hydrogen started radiolysis of water in the upper atmosphere. Oxygen remained, and hydrogen – dissipated. Later, when the Earth moved in from outer space holders nano-molecular peptide nucleic technology, the situation began to change. Apparently, these first settlers were stored after photosynthesis in the form of oxygen, peroxides, and hydrogen – in the form of hydrocarbons.
But if by the time of colonization of these intelligent ancestors of bacteria in the atmosphere and hydrosphere have been a lot of oxygen – oxygen store in the form of peroxide was not necessary …
But if, in the hydrosphere, or anywhere else would be an excess of hydrocarbons … Wow! ! It’s on Titan! That’s where the bacteria stockpile peroxide instead of carbohydrates! Yyess, it also goes in my sci-fi story! 😉
September 30, 2011 at 10:43 am #106504
Yes, the question, where did the carbon in the Earth’s atmosphere? And it got in touch with calcium and oxygen in carbonates. Yes, even in deposits shale, coal and oil.

Try to look for Miller-Urey experiment and more alike experiments which concluded origin of life .
September 30, 2011 at 5:34 pm #106514
I know we are going off subject a bit but it does have some relevance.
I agree about accretion theory. It creates more questions than it provides answers, but it is a poplar theory and that is why I cited it.
However the Laplace Black star model also has it’s problems.
By defination a Laplace black star has an escape velocity that is greater than light speed.
Any matter leaving it will be moving at less than light speed. Therefore it will return to the star as gravitation pulls it back.
It therefore cannot escape to form planets etc unless it travels at a greater velocity than the black star’s escape velocity.
I am not aware of any accretion mass that has been known to travel at above light speed.
However this is all really quite academic, because whether the atmosphere contained either CO2 or O2 it would not matter. Either way metabolic pathways could not get started.
The theory of photosynthesis is fundamentally flawed.
As I have stated before there is no scientific reason to conclude that the current atmospheric breakdown was any different to when life first started..
btw have you been in touch with James Cameron yet 🙂

Interesting, though the relevance seems to be as elusive as the scientific evidence.

I am a molecular biologist, in general, like biology, astrophysics, and much more! It’s a hobby, but I can find the necessary literature and now I can recognize manipulation. Here, for example, "black holes" of general relativity and the "Black Star Laplace" – it was interesting to me. I realized that the so-called "Black holes "of general relativity – is a clever manipulation, which deliberately ignored the kinetic energy! It turns out that the approach to the singularity of the density requires an infinite energy! And because there is nowhere to take it, then this state is not achievable. So there is only "Black Star Laplace".
October 2, 2011 at 11:06 pm #106572
Do I take it to mean that you consider the Miller-Urey experiments and other like ones to have answered the question as to how life originated, or did you mean that these experiments demonstrated the opposite?
Could you clarify please.
October 3, 2011 at 2:24 pm #106614
Raises the experiment of Stanley Miller back in the 1950’s.
I am not sure what his view actually is regarding the results, I await his clarification.
However his experiment and indeed succeeding ones did show one clearly noticeable feature.
Robert Shapiro had a comment on this in the edge event I have referred to before.
He recounts a meeting he had with Stanley Miller.quote :
The above is on a video clip here. (scroll about half way down to locate it)
The rest of his comment is transcribed below and is available in pdf form on the same site from page 90.quote :
The point that Shapiro is making, and he is an evolutionary scientist, is this.
Investigators design their own atmosphere that has nothing to do with the reality of prebiotic conditions.
They prepare their designs to try to achieve the result they are seeking. That is the start and end of it.
With these atmospheres that are cooked up in a lab, has any serious thought been given as to how that particular atmosphere could have naturally developed?
Of course not, because no theory can account for it.
Their atmospheres are specifically designed to produce the result they wish.
In the genesis narrative that is precisely what is stated. The atmosphere was specifically designed to accommodate the life that was to come.
Of course a materialist view says you can’t have an outside agency designing because science can only deal with natural processes.
The irony that seems to escape this type of thinking is that the very processes they are denying, they actually use to prove – what?
That the prebiotic atmosphere can only come about by design. 🙂

You’re using stupid logic. Just because we can create something, doesn’t mean, it must be created by someone.

I though you are an engineer, but obviously not in chemistry, right? So you have no education in related fields whatsoever, but you will complain all the time.
Nevermind, the point is, that oxygen is quite reactive and thus it reacts with the other elements and forms other compounds. If you knew anything about chemistry, you would know, that getting oxygen from SiO2 is really hard task.
Furthermore, there are other planets where there is oxygen in some compounds, but it is not in the atmosphere as O2 and this is no speculation. So why should we assume that the early Earth was different?
And how did the oxygen arise? Well, from the organisms, obviously.
October 3, 2011 at 10:12 pm #106620
Where did I say that oxygen formed from Quartz or Feldspar?
It didn’t and that is my argument. Please read what I am writing.
The oxygen must have been around in the compounds that formed the rocks according to the theory of accretion.
For it not to be around after the rocks formed must mean that all the oxygen was used up with no remainder, for any atmosphere. That was what I said.
Now is that realistic?
Because that is the theory of a pre-biotic atmosphere.
Therefore the question is where did the oxygen come from?
You sayquote :
So a simple question now
What organisms are you referring to.
Now think before you respond, as I have no desire to see you digging a bigger hole for yourself.

You said:quote scottie:
And I’m saying, that it’s basic inroganic chemistry, which tells us that.
So, where do you think does the oxygen come from if not from the rocks?
October 4, 2011 at 12:41 pm #106633
I am finding it very difficult to understand why you appear to not appreciate the obvious. Maybe it is a language problem
So may I try again
In my post that you refer to I statedquote :
If the accretion process from material that was rich in O2 formed the rocks and water all of which are themselves rich in oxygen, why is it claimed that the atmosphere lacked oxygen?
What is the physics or chemistry that justifies this claim?
I said there is none.
So for my education as I am obviously unacquainted with chemistry, can you explain a physical or chemical process controlling accretion that does, on the one hand make use of the oxygen rich material to produce the rocks and water, but on the other not leave any free O2.
You need to explain this if you are to state that there was no O2 in the prebiotic atmosphere, and even more bizarrely that “organisms” produced the O2.
I am saying quite clearly, with my limited understanding of chemistry, that if this process of accretion which so clearly assumes a material mass rich in O2 is correct, then this very same process would have had some remaining O2 as a constituent part of the atmosphere.
I hope that is clear enough
October 4, 2011 at 1:25 pm #106634
the thing is, that the materials such as sillicates are so stable, that they do not release oxygen, similarly other elements react quickly with oxygen to form oxycompounds. These are mostly stable, definitely more than free oxygen.
By the organisms, I mean of course the evolved bacteria. There are plenty of articles, which track the level of oxygen in the past. I’m sure, you will find some, since you’re so great with the resources 😉
October 4, 2011 at 8:19 pm #106639
Oxygen could get into the atmosphere once, 4 billion years ago when crossing the plume from the central galactic hyper-astroid Laplace in a place where centrifugal force is born spiral arm of the Galaxy. Nitrogen, by the way, too, like gold, and many other things! http://www.bbc.co.uk/news/science-environment-14827624

In other words you don’t know. 🙂
Now you are getting really careless in asking me to find your resource articles.
Do you really wish to be even more embarrassed? 🙂
However you have had a stab at what you refer to as "evolved bacteria" as the organisms that produced the oxygen.
So may I remind you what the chemistry involved is. The process your “evolved bacteria” would need is photosynthesis. The popular hypothesis that this “evolved bacteria” is cyanobacteria..
I explained all this to Leopol a little while ago,
by scottie » Thu Sep 29, 2011 1:05 pm
However lets try again.
Our current atmosphere contains about 21% Oxygen.
Now in the process of photosynthesis it takes one CO2 molecule (Carbon Dioxide) to produce one carbon atom and one O2 (oxygen gas) molecule.
So if there is 21% oxygen in the atmosphere now, then therefore must have been 21% Carbon dioxide in the early earth atmosphere.
Therefore what effect do you think an atmosphere containing 21% CO2 would have on life.
May I suggest fully absorb the reference to Venus’s CO2 enriched atmosphere and then consider how your “evolved bacteria” could have survived let alone got started.
Please stop looking for “fairies at the bottom of your garden” they are not there. 🙂
October 4, 2011 at 9:35 pm #106641
I think those ancient reasonable membranoids in Venus would create a special way of photosynthesis. They would have done such a super-heat-resistant catalytic process in which energy of absorbed photon was spent on a separation of CO2 – C + O2. Moreover, both components would be stocked in separate granules and vacuoles! And this technological structure would require the presence of special membrane rhizoids, which would look in the substrate compounds containing hydrogen – for exothermic synthesis of water! Energy would be allocated, by the way, can also be used for CO2 – C + O2!
October 4, 2011 at 10:14 pm #106643
The BBC love this type of headline grabber and treats reports such as this as fact.
The Nature article concludes with this acknowledgement by the authors.quote :

"membranoids" —- Not my type of music 🙂
October 5, 2011 at 7:17 am #106651
Well, actually, I’m not against accretion. Central hyper-astroid initially formed from the stars – the white giants that – the main population of elliptical galaxies. Such stars – pure hydrogen-helium white giants, as these galaxies formed by accretion (in my opinion). And later in the centers of these galaxies after falling stars on the growing star-monster appears hyper-astroid and stretched in the equatorial plane in a giant rotating spindle, which is detached from any planetoids and stars type "Main sequence".
Well, me, my "music" is quite suitable. Because this is my way to solve that problem, now called the crisis of the genre in molecular biology. Now the question is, what can explore methodological complex nano-phenomena in the cell membrane to describe it, "consciousness" of the cell – the "Active membrane model of the World on … Spirit? Continuum?" – Oh, what’s the difference? 8)

May I put this to you.
You have a sincere belief in the evolutionary hypothesis and I understand that and respect it.
However unless you can establish those views have a scientific basis, then it is only a belief system like any other.
In order to get life started, for evolution to get going you have to believe that the early atmosphere lacked oxygen.
So an atmosphere lacking oxygen had to be designed to test out the view.
That design, whatever the combination of gases,is confronted with major problems.
1) Many experiments involving an oxygen free atmosphere have produced amino acids, the basic molecules in living organisms. However the energy that created these molecules also destroys them. That is why Miller and others had to get them out of the system once created. What natural process could have done that? (The problem has not even been addresses as far as I know)
2) All the experiments produce both left handed and right handed amino acids in more or less equal quantities. The life processes use only the left handed ones. Right handed ones are toxic. What natural processes are able to differentiate between them?
3) If life did evolve in, say an ammonia/methane environment, that organism had to evolve into one that breathes oxygen. How did that happen? Again there is no plausible explanation that has been offered.
4) How did the oxygen free atmosphere become an oxygen rich atmosphere? There have been a few attempted explanations, here is a statement on the subject of photosynthesis that you have referred to.quote :
Science, Kasting, Vol. 293, 3 August 2001, “The Rise of Atmospheric Oxygen”, page 819
5) How did the genetic code evolve? Koonan for example refers to this as an intractable problem
Here we have a clearly designed atmosphere that has proved not to be correct simply because for the past 60 years or so all attempts to surmount these problems I have mentioned above have failed.
Clearly no natural explanation has proved plausible. That is not in doubt.
When I suggested that the only plausible answer was that the atmosphere was clearly designed correctly with it’s O2 content right at the start of life that is also designed all those problems go away.
Yet you responded this wayquote :
Now forget that I am using stupid logic as you put it, would you like to rephrase the second half of your statement because it makes no sense to me.
I simply do not know what you mean.
October 6, 2011 at 7:34 am #106672
You know, I’m tired of arguing with you. That’s problem of all of you, anti-evolutionists, you rather beat your opponents by writing lots of long posts, which may sound nice (how else would you get followers, right?) than by true arguments.
You are trying to look clever, but the least mistake you’re doing is mixing origin of life and evolution. You should make it clear for yourself first, what are you talking about.
Regarding the oxygen, I know there are some articles, I have read some, but I’m not much willing to spend time searching them now (yeah, I’m sorry, but my memory is not that good to remember every article I’ve read years ago). But you’re obviously using only these facts, which are usufull for you.
The fact, that we can create something is not proof that it must be created by someone and it cannot "evolve".
October 6, 2011 at 10:48 am #106674
In other words you only believe what you think you know, but can’t be bothered to actually find out if it is correct.
That’s fair enough, belief based on emotion is a very difficult thing to combat, why should you want to change your comfort zone for the real world. 🙂

Jackbean (and other participants in this thread).
It`s a mystery to me why you all encourage this pseudoscientific monologue to go on and on and on. Your arguments are only adding fuel to the fire. And you should know it. It`s like debating holocaust- deniers. You can newer answer all their shoe box questions and their citing of known and unknown historians. So you don`t do it. You know their motives and you know their tactics and you don`t invite them into an arena of honest and open thinking. It`s not about censorship, but about decency, really. On a biology forum I would not expect creationists given free space to prove their point that science can`t agree on the basics of life on earth. This thread serves to verify the“fight” inside the science community, which we know is false, but nevertheless demonstrated here. Science is about placing evidence before conclusion, not the other way around, like creationists do. Yes, I took this forum to be a science forum. But this never ending stream of modern day creationism proved me wrong. It`s a pity.

In the Soviet Union was such a terrible time – Stalinism, and then was biology – Lysenkoism. Then the right was declared dogma Trofim Denisovich Lysenko, certain, and everything else – was considered the machinations of world imperialism. Then anyone who did not agree with the dogmas of Lysenko either shot or sent to concentration camps for life. Well, now we have some new trends on a global scale! .. The scientific controversy – administrative arguments. All learn to get version of evolutionary theory "from simple replicators to evolutionary crown of creation" and to ban argue with that! And anyone who does not agree – to declare "creationists" and "excommunicated", that is only true of the "admin-science"!

Sorry for the delay.
I didn’t know about Lysenkoism., so I had to do a little research.
I get your point though.
If only serious minded people would put their religious beliefs aside when discussing science matters there would be a lot less angst around. When I use the term religious beliefs, I include the materialists who after all claim to be atheists.
In the past the Churches ruled the roost and demanded allegiance to their dogmas.
That has now been taken over by the material atheists who demand the same allegiance, with the creationists and Id people trying to reclaim their lost ground.
Darwinism has now become the new dogma and any other view is crackpot and deserves only ridicule.
Although that is now changing again.

Darwin’s theory – "On the origin of species by natural selection." Vulgar evolutionism – a hybrid between Darwin’s theory and the idea of the origin and evolution of life from primary primitive replicators to "crown of the evolutionary creation" – Homo Sapiens-sapiens-sa-…xn…-ns… Meanwhile, Darwin’s theory does not contradict the theory of devolution! Quite the contrary – a perfect match. But only at those stages when there is no intellectual activity and create and develop technology.
Here’s an interesting example of devolution – the distribution of gene technology between the new species, outgoing from the initial species of the universal type.
"In all vertebrates, some insects and mollusks in the blood protein is present ferric iron, but because their blood has a red color. Blood clam brachiopods contains hemerythrin – it contains iron to five times more than the hemoglobin. Oxygenated blood hemerythrin gives a purple hue, and gave oxygen to tissues, such blood turns pink. In polychaetes – the other iron-containing protein – hlorokruorin. The basis of it is not ferric iron, ferrous and which gives the blood and tissue fluid green. In ascidian blood is colorless, it is based – gemovanady containing vanadium ions. In octopus, spiders, scorpions, crabs, respiratory pigment of the blood is hemocyanin, in which iron is present instead of copper (Cu2 +). Combines with oxygen of air is blue hemocyanin, and by giving oxygen to tissues – a few discolored. As a result, the arteries flowing dark-blue blood and the veins blue. However, some shellfish oxygen transport of substances close to the hemoglobin, and other similar proteins contain manganese." http://otvet.mail.ru/question/16010365/
That’s because, as interesting! Some evolutionists, created a series of painful anthropocentrism taboo. For example, some evolutionists reject even the thought of which created a strong di-polivergence of species of amphibians-Turbellarians in the Cambrian paleo-civilization, who had blood all at once these blood pigments! 😉

Lets get back to basics.
The cell is the basic unit of life.
No one has disputed that simple fact.
All the internal molecular systems inside the cell are, in themselves, inert.
Again no one has disputed that.
The simplest form of life is a single cell prokaryote,..
Again no one disputes that.
E coli is a single cell prokaryote and is classed as a species of bacteria.
Again I don’t expect any one to dispute this either.
It is obvious therefore that the basic unit of life is also the basic unit of a species
Therefore the origin of life and the origin of species are one and the same thing.
Proteins are probably the most important class of biochemical molecules, although of course lipids and carbohydrates are also essential for life. Proteins are the basis for the major structural components of animal and human tissue.
A Ribosome is a molecule consisting of two subunits that read the genetic sequence and makes Proteins.
A prokaryotic ribosome is made up of three kinds of ribosomal RNA (rRNA) and about 50 types of protein.
The eukaryotic ribosome, however, consists of five types of rRNA and around 80 types of protein.
The cell membrane or plasma membrane is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. It basically protects the cell from outside forces.
Integral membrane proteins penetrate or are embedded in the phospholipid bilayer.
Without the membrane to protect it the cell would disintegrate.
This is all pretty basic biology that even an engineer can comprehend. 🙂
Now here is the dilemma for any origin of life biologist.
The Ribosome manufactures the protein, but it itself is made up of at least 50 proteins.
Ribosome cannot exist unless there are Proteins around.
Proteins cannot exist unless there are Ribosomes around.
The cell membrane cannot exist unless there are proteins about.
Ribosomes and Proteins cannot exist unless the is a membrane around.
This is one of the many conundrums the cell exhibits.
Neo Darwinian theory centers on Natural Selection as being the process that drives the evolution of living organisms.
It is obvious the proteins along with the other cell components are inert and therefore cannot be subject to any process of natural selection. The only laws applicable to any inert molecules are the natural laws governing physics and chemistry.
As I have reported before, there are no plausible natural biochemical pathways that lead to the formation of a cell. This is coming from the most august of scientific Institutions.
There is also the matter of the origin of the genetic code which again is being shown to be, not a natural process.
Therefore the only plausible pathway to cell formation is an artificial process. This is a process that is regularly demonstrated in Genetic Labs around the world.
However the difficulty goes beyond that.
Even if we assume that somehow the cell can or was constructed there is still the problem of how the cell can come alive.
This can be said for two reasons.
1) Viruses are very complicated molecules made up of proteins, nucleic acids, lipids, carbohydrates etc. Yet they are not considered alive because, without cells they are unable to multiply. There are other reasons as well. Now if these very complicated molecules made from basically the same ingredients as cells, do not constitute life, it shows that that life is something more than the bringing together of these very complicated molecules.
2) We already know that life comes only from another life. This is an established biological fact.
These conclusions are based on science, logc and evidence.
What prevents any biologist from acknowledging these conclusions other than a philosophical bias?

Scottie, hrotects the cell cell envelope. Membrane does not protect, but a universal substrate for placement and activation of polypeptide production lines and signaling. This is in terms of technology. But the logic of the theory of "Engineering design and the Macrodevolution" of the membrane – a direct descendant of those smart membrane beings who once created a nucleic polypeptide molecular nano-technology.

Correction — What I have shown is that there is no natural explanation to the origin of the cell.
Maybe you need to do some more work in your understanding of language.
Certainly your understanding of biology is at best, a "work in progress".

Let get some more basics up front.
Two among the most prominent evolutionary proponents of evolutionary theory today are Richard Dawkins and Freeman Dyson.
Here are some extracts from an email exchange between these two scientists.
Freeman Dyson view.quote :
Dawkins response by email is here.quote :
You will find this exchange from the recent discussion “Life what a concept” at the Edge Special Event.
You will need to scroll down almost to the bottom of the page.
So whose is right?
Is it Dyson, whose understanding of Darwinian evolution is based on Competition between non interbreeding species
Or is it Dawkins view based on competition for survival within species.
What does this say about any factual basis for the theory?
Is it any wonder that no one on this forum was confident enough to explain their view. I eventually had to spell out one view to even elicit a response.
It says nothing other than merely reaffirming my statement that this is all about philosophy.
October 15, 2011 at 5:08 am #106896quote scottie:
Very funny, scottie.
You are arguing that the cell cannot function since the ribosome is part protein, and the ribosome is responsible for peptide synthesis; therefore, according to you, the protein cannot be part of the ribosome. Yet, obviously this is not true. Because the ribosome seems to be ubiquitous in almost all organisms, the ribosome must have originated very early in the history of life. Ribosome evolution began with a complex of nucleic acids that probably had another function early on, but acquired the function of protein synthesis. Only later were proteins incorporated into the ribosome.quote scottie:

I’m not willing to slog through 23 pages to try to figure out what’s going on here. Reading through a few random pages, though, I can’t see what most of this has to do with the origin of life. All I can discern is the standard, tiresome creationist/rationalist crap sprinkled with a dash of delusion. Is there a point to any of this, or do all of you just have too much time to waste? May I suggest that individual discussions have their own threads? This one just seems to be a dump for anything anyone wants to say.
Scottie: can you state your position in 25 words or less (concerning the origin of life)? If you have something else in particular you would like to discuss, could you please start a new thread?
Leopol: What’s the weather like on your planet? Photos would be welcome.
The origin of life is, of course, a very interesting topic, one that has entertained me for a very long time. I know I will die without ever knowing how it occurred, but that has never detracted from the enjoyment of my ignorance. Ignorance is what science feeds on. Anyone who says "I know" or dares to use the p word (proof) is automatically disqualified.

Your statement above is what you believe.
What evidence can you call upon to substantiate this.
The simple answer is, you are not able to. You can only hypothesise.
Therefore it is only your belief. And if that is what you wish to believe, then believe it.
But don’t parade it as scientific fact.
Look even accomplished biologists like Craig Venter , George Church and others including NASA itself openly acknowledge that there are no plausible pathways to these complex biochemical molecules.
Have you not bothered to read the papers and articles from prominent members of the Evolutionary establishment that I have referred to.
Or are you suggesting you know more than them.
Please, please don’t say Yes. 🙂
October 17, 2011 at 1:41 pm #106955
What I am trying to get over is really quite simple, both in terms of logic and biology.
Now please read carefully.
The Ribosome is an essential part of every cell. It is regarded as one of the most complicated molecules in the cell.
1) It is made up of proteins .
2) It also manufactures the proteins in the cell
3) In other words it manufactures the very proteins it is made from.
How can that be?
Well the only way this can come about is for a protein to be designed and manufactured .
The process then repeated some 50 times or so.
A translation system must then be designed and built.
A Ribosome can then be constructed with these molecules.
Then there must be some method of inserting the translation system that can read the coded sequence of amino acids.
The Ribosome can then be placed into the cell so that it can (along with all the other systems in the cell) commence the manufacturing all the proteins the cell makes.
In other words some outside agency must be involved in the process.
No natural laws have the capacity to do this because natural laws do not function in this manner.
This is a process that some biologists are beginning to attempt to do.
Can you understand why I say that there is no natural process that can overcome this conundrum.
It requires an outside agency.
October 17, 2011 at 2:55 pm #106959
As I told you already dozen times, the crucial part of the ribosome are the rRNAs, the proteins are just added cosmetics. But you refuses to accept that. You think that if something is nowadays composed from proteins, it had to be composed of proteins billions of years ago.
I’m just curious. This "outside agency" is composed of proteins as well or is it of something else?
October 17, 2011 at 6:23 pm #106968quote JackBean:
That’s an interesting way of handling the "unnatural" influence question.
October 18, 2011 at 7:40 pm #107004
Ribosomes are made from approx 40% proteins and 60% nucleic acids (rRNA )
So, proteins are just added cosmetics.
Is this supposed to be a serious statement?
Let me take you to a basic biology refresher.
The Ribosome is the translation system for the manufacturing of proteins.
This process starts with Transcription.
This is the first step in decoding a cell’s genetic information. During transcription, Enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix.
What is an enzyme?
Guess what? It is a protein.
So our basic refresher tell us that a Protein is required at the start of a process to make (guess what?) a Protein.
http://www.nature.com/scitable/topicpag … n-14120660
Now let’s look at your rRNA.
How does the rRNA come about.
One of the non ribosomal proteins the nucleolin, is considered to play a key role in the regulation of rRNA transcription, perisomal synthesis, ribosomal assembly and maturation.
http://books.google.com/books?id=P_ajeM … &q&f=false
So which came first Protein or rRNA?
Biology is clearly not a strong point with you.
Has it not dawned on you yet, the point is not whether proteins are the crucial part or not.
The point is that Ribosomes, made from proteins, actually make the proteins.
That’s the conundrum. So how does that work then.?
Got an answer? Of course you haven’t, because there isn’t a scientific explanation based on natural processes.
So how best to cope with that scenario.
Well that’s easy, just pretend it doesn’t exist and ignore it.
This is what is called wilful blindness.quote :
Do you mean that I refuse to accept the so called RNA (world) hypothesis as a fact.
If that is what you mean then you are correct.
I do not accept hypothesises as fact until there is sufficient evidence to confirm them.
The fact that this is still a hypothetical scenario even within the biological community, speaks for itself.
btw cyanobacteria is regarded as the oldest living fossil and is dated to 3.5 billion years ago. And guess what, it contains proteins.
October 21, 2011 at 7:34 pm #107097
The conventional dating which provides the backdrop upon which all evolutionary theory is presented, reveals some interesting information regarding fossils.
The fossils of cyanobacteria are particularly significant.
http://books.google.co.uk/books?id=OKkT … &q&f=false
Their ability to carry out oxygen producing photosynthesis is a universal characteristic of cyanobacteria that distinguishes it from all other prokaryotes.
These fossils found in Western Australia are dated to at least 3.5 billion years ago.
We don’t know as yet how much earlier they may have existed.
However these prokaryotes are fully functional unicellular life with fully functioning transcription and translating systems manufacturing proteins, and of course they are still around today in huge quantities.
Again according to conventional theory the earth is 4.5 billion years old.
And according to the same US Geological Survey the oldest dated rocks in Western Australia are 3.4- 3.6 billion years.
This places the appearance of cyanobacteria around the same time as the appearance of the first rocks and therefore does not leave much if any time for any evolution to take place, let alone such a complicated life form as cyanobacteria which has the additional system of photosynthesis that other prokaryotes don’t.
There is of course more to this.
In the Jack Hills of Western Australia scientists have uncovered very interesting evidence of the early earth conditions over 4 billion years ago.quote :
So the evidence from the US government agencies is painting a picture of an early earth of oceans. A land mass then appearing and the first fully formed complex life appearing in the rocks around the same period.
Where have we read this scenario before?

Well I am glad you appreciate what it is like be subjected to a little bit of sarcasm.
Let me also remind you of your rather sarcastic post to me to join another thread.
Also to threaten to block any further posts from others on another thread because you happen to disagree with them and even insult their religious belief, I found to be in very bad taste.
I have always tried to be polite to you in all my posts and have even apologised when I have poked a little bit of fun, even though I was responding in kind to your own sarcastic questioning.
I have always made it clear that I do not discus religion because of all the obvious emotions that manifest themselves, because when emotions take over truth is invariability a casualty.
Now you clearly believe that evolution, (something that you still have not been prepared to explain in any detail) is the answer to the Origin of Life.
I don’t have a problem with that, except that you insist that your belief is actual science.
If you insist that your belief is founded in verifiable science then you must show that to be the case. Simply stating that it is a fact, is not science.
Now let me try once again and answer your questionquote :
By referring you to my post to you on Tue Jul 26, 2011 10:16 am
I explained very clearly my understanding of design and the reasons for it.
I also asked that if you disagreed then to please explain where I was wrong.
You chose not to respond to any further posts until I posted on Quorum sensing, when you responded on Sun Aug 07, 2011 8:09 am
I replied in great detail the following day at which point you again went silent until the 30th August when you jumped in again as the discussion had move on.
All of this reveals to me that you don’t wish to debate your own views except to state that they are science, but keep looking for opportunities to find fault with someone else post.
If that is your tactic then fair enough I have to live with it.
However it only reveals to me that you do not have the confidence in your own view to debate it scientifically.

I don’t see how much clearer I could have been.
As you can see I asked for a response – You didn’t oblige
The information that controls the cell operations in a human cell differs from the information content of cells from other species.
Differentiation is simply one clear example of that. There are of course more examples.
The Functional and indeed specified information found in cells is not the product of natural forces.
The only known source of this type of information is from a mind.
If you disagree then please inform me how else it can come about.?quote :
I don’t argue with that.
The point I was making is that there are different levels of information regulating cells. Where those levels of information that reside in the cell are, is not known to science.
Hence my argument, that changes in DNA only effect the type of protein manufactured, and usually to the detriment of the cell.
That is why there is such an elaborate system of feedback and error correction in cell processes.
This very system of error control is evidence in itself of design.
I didn’t report NASA spoke about the mind. I said NASA acknowledged that “an external source of free energy” was required.
I said that that external source can only come at the express will of a mind. In other words an outside agency is required to produce the design we see in the cell.
I hope that is clear enough.quote :
I agree that a scientist should not say he knows 100%.
When you say we have “ hypothesis and theories for which you have proof”
That sounds like 100% to me.
Also hypothesises are by definition not proven. When a body of information begins to support a hypothesis then, and only then may that hypothesis be elevated to the status of a theory.
Every real scientist knows that.
The RNA world idea is a hypothesis. It has not been elevated to the status of a theory because the evidence does not support it. This is what NASA was reporting on.
October 27, 2011 at 12:38 pm #107359
Jackbean has argued that origin of species is not the same as the origin of life.
These are two separate matters, and evolutionists only argue on the subject of origin of species.
Now I have argued differently, stating that they are the same.
However let’s assume Jackbean’s view is correct and see where that leads us.
Now the data from the various DNA sequencing projects in animals and plants have revealed some quite surprising results.
For example the genes found in a mouse are for the most part the same genes found in man. There may be slight differences but are clearly the same genes. The same with man and fish that are, for the most part also, the same genes. Even further than that, the Genes in man and chimpanzee are almost identical.
Not only are the genes the same, but the base pairs in these genes are often identical.
http://www.ornl.gov/sci/techresources/H … pgen.shtml
We know that new proteins rarely evolve by point mutations in existing genes to create new genes.
However there is this process called Exon Shuffling.
After a mRNA sequence is transcribed from the chromosome, a protein called a Spliceosome will cut out sections of the gene sequence, these sections are known as Introns.
What these Introns do is to break up the instructions for making the proteins. Therefore the Spliceosome has to cut out these sections of DNA and join the remaining pieces (Exons) together.
This brings different protein domains together in the final protein when it is translated. Through this process, one gene may encode many different proteins.
Here is an excellent visual of this process
http://highered.mcgraw-hill.com/olcweb/ … cess%20RNA
So to summarise
Exons are the coding area in a genome that produce the genes that make proteins.
Introns are stretches of DNA, within those coding areas, that have to be spliced out before the mRNA can be prepared for transport to the Ribosome for manufacturing protein.
These Spliceosome Introns have been quite puzzling to biologists, because although they are numerous in Eukaryotes ( plant animal and human cells) we don’t observe them in Prokaryotes.
Additionally some Eukaryotes like Yeast have a few of these while Humans have tens of thousands of them. The more complicated the organism the more Introns.
So the puzzling question for biologists is to determine where these came from.
When new information is required this is achieved by re-using existing information. This depends on the initial information and how this information must be shuffled in order to create new information.
Exon shuffling and mRNA splicing are both highly complicated events in eukaryotes. However the primitive self-replicating cells, ie prokaryotes, cannot implement such a system.
Not only do they lack the information to shuffle but they don’t have the machinery to shuffle it.
Therefore the first gene could not have been created by re-arranging and shuffling existing information because there was no information or mechanism to shuffle and rearrange.
Hence the additional puzzling questions that Biologists are trying to grapple with.
How did the information and the machinery come about for gene creation in Eukaryotes?
Remember that evolutionary theory posits that prokaryotes evolved into Eukaryotes by a process of random mutations of the genome and then filtered by the other process of Natural Selection. All of this cementing the other pillar of evolutionary theory – Common Ancestry.
Here is a 2006 paper that tries to deal with this problem.
It is entitled “Phase distribution of spliceosomal introns: implications for intron origin”
This paper is also referenced by our very own biology online article here
http://www.biology-online.org/articles/ … tract.html
This paper examines two competing theories. ( I use the word theory loosely)
One theory relies on an organism called a Progenote.
Now what is a progenote?
Well the progenote is a hypothetical candidate for the last universal cellular ancestor. There are two major conjectures associated with this entity: (1) the progenote’s genome is based on RNA rather than DNA and (2) the replication, transcription and translation of this RNA organism had a much higher error rate than the ensuing DNA-based cells.
http://onlinelibrary.wiley.com/doi/10.1 … 3/abstract
So here is one explanation that requires a mythical organism and then goes beyond that by having two major conjectures associated with it.
And of course ones like me get berated for not calling this science. 🙂
So what about the other “theory”
Well I had better leave that to another post as this one is long enough.
Don’t want to add to my “long-winded reputation” 🙂

1) they were created when all the other life on Earth was created few billions of years ago

I will try it differently: hypothesis and theories for which we currently have proofs. Think about Newton, who saw the apple to fall down and came up with gravity. Einstein had more proofs and came with his theories. Now we may even find his theories false, since there were detected neutrinos faster than light.

My sincere thanks to the moderators for allowing me back on the forum.
October 29, 2011 at 11:01 pm #107429
May I clarify some points from my last but one post.
1) When I discussed “Exon Shuffling” in isolation, it was not intended to show that it was the only method of new information.
I am fully aware of gene duplication as another method. In fact I believe I was the first to introduce it into this thread back in August.
The point I was making was that, there had to be existing splicesome introns to shuffle in Eukaryotes, plus of course the mechanism to shuffle those introns..
As this is a vital process in transcription The question of how and where these introns and the shuffling mechanism came from is what the hypotheses I referred to were addressing.
Now clearly the so called early theory is not preferred by the article this forum has cited.
In fact the article prefers the late theory.
It has it’s own set of difficulties but that is another story.
2) Design theory is falsifiable.
In a previous post I pointed to one way in which it would be falsifiable.quote :
starting at this statement.quote :
If this theory is falsifiable then it can seriously claim to be a scientific theory or hypothesis.
I made it very clear how it can be falsified?
That was in June of this year and no one has attempted to do just that.
Now until that happens Design theory must still stand as a scientific theory or hypothesis.
That is all I am claiming.
I did end that post with a request as to what is falsifiable about current neo-Darwinian theory.
As yet there has been no response.
Hope that clear matters up.

If phylogenetic data, either morphological or molecular, were unable to build trees, or if the morphological data showed no relation to the molecular data.
October 30, 2011 at 11:16 pm #107456
Let me see if I understand you correctly:-
We can observe certain morphological characteristics in a particular group of taxa of say (plants) and use this data to draw conclusions about the evolutionary relationships between these organisms.
Having observed morphological characteristics of this group of different plants we can now examine protein sequence in the same or related plant species to perform cladistic analysis.
We can therefore compare the results of phylogenetic relationships obtained using protein sequences (molecular data) with the results obtained from using morphological data.
For example if cactus (Schlumbergera truncata) and spike-moss (Selaginella) were in the group chosen we would note that they appear to have very similar leaf-like structures, but we would come up with very different evolutionary origins in the molecular data.
How does this support or falsify evolutionary theory. I don’t understand your point.
Could you clarify please?
There is of course controversy within the evolutionary community on the value of morphology in producing lines of decent.

But thanks your view is now clearer.
Decent with modification
Or as Richard Dawkins put it in his book
Unweaving the Rainbow: Science, Delusion, and the Appetite for Wonder, p. 201.quote :
If that is what you mean then,
Yes, that would and indeed does make the theory falsifiable.
So a tree arrived at cladistically showing decent with modification would be one such way to test the data. If a tree cannot be produced then that would constitute falsification.
That’s a good test.

I take it then that a tree cannot be constructed.
I don’t need to quote mine as is suggested because I have read Dawkin’s books. Though I do find books on religion and philosophy quite tedious.
I have also read Origins and have found that much more interesting.
The Cambrian phyla appeared without any Precursors and that is why eminent biologists like Wray, Levinton and Shapiro have attempted to provide molecular evidence for a common ancestor.
There is a clue for you.
Much more interesting than you tube videos.

Thank you for unlocking this thread.
Whether it’s humans, Trilobites, Brachiopods or any other form of life,there is no scientific answer.
There are only hypotheses.
However from the evidence of the Cambrian strata complex multi=celled creatures first appeared around 550 million years or so, ago according to conventional dating. There is no evidence of precursors.
Certainly no evidence of human fossils have been found in this strata as far as I am aware.
I can only conclude that humans first appeared sometime after that.
I will be able to respond to your question in the next post. It will be a little later as I have to be elsewhere for the next few hours or so.
November 10, 2011 at 4:36 pm #107992
so humans evolved from "lower creatures"?
November 11, 2011 at 12:35 pm #108039quote :
I have been arguing against this. I thought that point has been well established.
I don’t accept humans evolved from any other life form.
One of the lines lines of evidence to support my argument is the fossil data from the cambrian radiation.
The sudden arrival of multi celled organisms with basic individual body plans.
After some 150 years of searching no precursors have been found in any lower strata, which of course mitigates against common ancestry.
Without common ancestry where does macro evolutionary theory, in whatever form, stand?
November 11, 2011 at 12:39 pm #108040
You raise a valid point regarding Stephen Gould’s view of Punctuated Equilibrium. There are of course several others with their own hypotheses as to how the process of macro evolution works.
Carl Woese with his hypothesis of an early era of considerable Horizontal gene transfer.
Simon Conway Morris with his idea of “front loaded” evolution
Lynn Margulis — Endosymbiotic theory
James Shapiro — Natural genetic Engineering
I could keep on with such leading names as, Allen Orr, Daniel Dennett, PZ Myers, Michael Ruse Coyne etc etc, All tearing lumps out of each other. Their email exchanges can be quite vitriolic at times.
Freeman Dyson and Richard Dawkins can’t even agree with each other as to what Darwin’s theory actually is.
These of course are all evolutionary scientists and philosophers.
So who is right?
They can’t all be right.
That is why I have repeatedly asked the question without response, as to what particular version of evolutionary theory ones opposing me subscribe to.
Well under all this rhetoric there is a body of evidence that no one has been able to explain.
In part I am referring of course to the Phyla radiation in the Cambrian strata.
This is solid evidence.
You appear to ask the question if I can prove the non existence of these precursors.
Well how do you prove something doesn’t exist if it has never been found.
However Erwin’s paper that I have referred to does provide some interesting new thinking on the subject.
November 11, 2011 at 1:06 pm #108041

I guess you didn’t follow my suggestion of doing some research into the Cambrian explosion (avoiding any sources from religious organisations). I still encourage you to do so, but I’ll just make a few pertinent points here:
1) very few organisms fossilise, especially those without hard parts, which means,
2) the fossil record has gaps, and always will, because, in part, of 1),
3) gaps in the fossil record do not represent the falsification of evolution, they just represent gaps in the fossil record.quote scottie:
Exactly! In science, falsification requires evidence, not lack of evidence. As the old and worn saying goes, absence of evidence is not evidence of absence. When all the fossils that have ever formed have been found, get back to us. And all the parts of the tree of life that strongly support common ancestry (and not just animals) mean what, exactly?quote :

Again are you suggesting that ones like James Valentine of University of Berkeley is a religionist or that Berkeley is a religious organisation.
Please lets not invent strawman arguments.
Let me though, take your points in turn
1 & 2quote :
It is true that shelled creatures leave a more extensive record than their soft-bodied
counterparts. However you are aware are you not, that fossils of soft body organisms do appear quite extensively in the Cambrian layer.
Soft-bodied phyla, such as Annelida, Onycophora and Priapulida, which do not have mineralized skeletons, make their appearance in the early Cambrian of Chengjiang, Yunnan Province in China..
The Mid Cambrian Burgess Shale fauna from British Columbia, preserves many soft-bodied fossils similar to those of the Chengjiang fauna. This indicates that these forms were widespread and persisted for many millions of years. These faunas only serve to emphasize the spectacular diversity that was achieved so early in animal history
Indeed cyanobacteria (ie soft body organism) are dated at some 3.5 billion years.
So to suggest, as an argument, that the fossil record has gaps because soft body organisims don’t fossilise, clearly lacks credibility.quote :
Did you not state this as evidence of falsification.quote :
When I produce evidence of the inability to produce a tree, you start to argue gaps.
Can a tree be produced or can’t it, at least for the present?
What is wrong with an admission that it can’t, at the present.
Instead of course you accuse me of researching religious data, which clearly I was not and you know full well I wasn’t.
In fact I am the one referencing peer reviewed papers from the evolutionary community.
Please advise, when have you referred me to a peer reviewed paper?
I simply report what evolutionary biologists themselves are acknowledging about the lack of precursors.
You seem to forget what Darwin himself acknowledged. And he was the originator of this idea. (well almost).
So then as I understand it, this is your view of science.quote :
So when some organism suddenly appears fully formed in the fossil record, this is not considered evidence of, some organism having suddenly appeared.
It is considered as a lack of evidence, that it had precursors.
I have to assume this is your line of argument since you go on to statequote :
It seems to me that while this "the old and worn saying " may be true, some further steps have to be taken to prevent this statement from becoming something like
"You can posit any hypothesis whatsoever for which no definitively contradicting (or falsifying) evidence can be found".
Now there are clear dangers connected with such an attitude.
Hypotheses, by their very nature, contain the very elements of their own potential falsification. You cannot assert a well posited hypothesis without also revealing the ground on which the hypothesis may be refuted.
I genuinely thought that you did just that initially. Sadly however you have resorted to a debating tactic rather than relying on science.
Perhaps I could conclude this point with Karl Poppers observationsquote :

November 14, 2011 at 7:49 pm #108102
Here’s how science works. Pay attention. Observations are made. Hypotheses are presented that attempt to explain the observations. If a verifiable observation falsifies an hypothesis, the hypothesis must be rejected or revised. You oppose evolutionary theory. What observations do you have that falsify evolution? An incomplete fossil record IS NOT AN OBSERVATION. What you will not understand (i.e. won’t accept) is that gaps in the fossil record do not falsify evolution. THEY ARE ONLY GAPS.
Outside my window I can see no airplanes in the sky. This is evidence that there are no airplanes in my field of view. Not proof, but evidence. Maybe there is an airplane within my field of view, but it is too far away for me to see. Maybe there’s one behind that cloud. It is not very good evidence that airplanes do not exist. If I do see an airplane, that’s pretty solid evidence that airplanes do exist. Do you see the difference between an observation and the lack of an observation as evidence of something?
Again, what about the rest of the tree of life?

scottie, again not responding?
November 15, 2011 at 6:08 pm #108127
Not only is the existence of gaps a faulty argument against evolution, as Gavin just explained, but it is nearly impossible to produce an evolutionary progression on our world without gaps. Finding a "missing link" closes a gap but creates two smaller gaps on either side of it. In order to close every "gap" completely we would need nearly every organism in a line of descent, as each descendant probably had some minor variations with the generation above it. This is impossible when fossils are so hard to come by.
But that does not mean that all those gaps disprove evolution! In fact, another important part of a scientific theory is its predictive ability. Time and again evolutionary scientists have predicted that we should find an intermediate "missing link" organism in this area of the fossil record with these traits and paleontologists have found exactly those predictions. Evolution is a very powerful and fully scientific theory.
November 16, 2011 at 10:56 am #108154
So let me get this right
Evolutionary theory is now only a hypothesis. Is that what you are saying?
Well if that is case then I agree with you.
November 16, 2011 at 2:49 pm #108158
There’s not much point in any further discussion about science and evidence. What I’m curious about is why you oppose evolution. Those who do are usually religious, but you say you believe in no gods. At least in no theistic gods. Are you a deist? But most versions of deistic gods just create the universe and then sit back and let it do its thing, including cosmic and biological evolution. I just can’t believe that you are an atheist who opposes evolution because of a lack of evidence. Would you mind stating (in 25 words or fewer) your version of things so we can understand where you’re coming from?
November 16, 2011 at 6:40 pm #108175quote scottie:
Evolution by natural selection was a hypothesis, but a hypothesis which accurately explains the observed data and phenomenon and makes predictions which come true becomes a theory. Evolutionary theory explains all the data and phenomenon we have so far observed and has even made predictions which have come true (both in the lab and in the fossil record).
November 16, 2011 at 7:44 pm #108177
I don’t think I can stick to 25 words or fewer, so please bear with me.
Firstly I don’t oppose evolution in the strict meaning of change over time, by whaterver natural means. Evolution in that limited sense happens.
What I don’t accept is that this natural course of change over time as described above produces new species. In other words Darwin’s hypothesis is being shown to be wrong.
Design is what I see the biological world revealing.
Now if that design can be explained through natural processes then I have no problem in accepting that. Otherwise that design must be by some outside agency.
This is not a religious question to me.
I think for myself I don’t need or desire for the dogmas of others, be they religious or scientific.
The only belief system I rely on is the scientific method.
This essentially involves four steps:
There are Observations,
Then the formulation of a Hypotheses to explain the observation.
That produces a Predictive capability.
And finally devise Experiments to test the hypothesis.
Now if that method does not provide the data in support, then at best, the hypothesis is not proven (in the scientific sense) and so remains a hypothesis.
If data can be shown to support, then depending on the quality or quantity of that data the hypothesis may be elevated to the status of a theory,
I have not seen any evidence that Darwinian (or Neo Darwinian) views fits the status of a theory. It is simply a hypothesis. The Cambrian fossils are but just one example of data not fitting the hypothesis. There are of course several other lines of data that my posts have referred to.
If there is evidence then point me to it, ie peer reviewed papers, and I will certainly examine them.
Statements like "evolution is proven" is not evidence. They are just statements unless accompanied by evidence.
What I have seen in this discussion are the philosophical and religious views dominating over the actual data. A lot of heat but very little light.
That is why I got involved on this forum.
I am quite happy to answer any other questions you may have.
November 16, 2011 at 8:49 pm #108182quote scottie:
Yes, we know. Are you a philosopher? They are notorious for being poor communicators. They are also notorious for being scientifically illiterate. You are obviously not scientifically illiterate.
Here’s my version: I know squat for sure, but the evidence seems to favour a Darwinian process for the production of new species. (20 words)
Believe it or not, but we may actually be partial allies. I’m a relative hardliner when it comes to absolutes, such as claims of absolute truth. I’m generally a Dawkins fan but cringe a little when he continually says "evolution is a fact" or when Coyne writes a book called "Why evolution is true" (I haven’t read it yet). The word "proof" is horribly abused in all human endeavours. Proof outside of mathematics is a rare thing indeed, and even within mathematics, proof is only claimed given a certain set of unproven axioms. I try to avoid the word "proof" altogether, and in lieu of "fact" and "true", prefer "very likely a fact" and "very likely true". My view is that science can, at best, help to determine the probability of truth.
Your reluctance to clearly state your position finally forced me to visit earlier postings to this thread to try to determine your position. You have stated that you believe in the veracity of science. So do I. You have also stated that you accept an evolutionary process occurring within species but not as a process that can produce new species. You seem to believe that design can be seen in nature, but that design has not arisen by a materialistic process. This implies that you believe in a nonmaterial designer. I am an atheist. Some atheists don’t like using the word "believe", because they say that belief implies faith, and they don’t like using the word "faith", because it implies religious faith. I’m not so queasy about using these words. Since I am a bit queasy about using the words "fact", "true", and "proof", and I have to use words to communicate my position, I say I believe something or have faith in something, meaning that the evidence to date supports the likelihood of that something being true.
The scientific method, in an organised manner, has been applied for only a few centuries. It has helped us to come to a better understanding of many things. But we do not know how much we do not know. Duh. Hence, my beliefs remain conditional. And this is where probability enters my picture.
Back to evolution. Your stance is that new species do not arise through a Darwinian process – no observation has indicated that any have. I know that various claims have been made that speciation has occurred within historical times or has been observed. Let’s not debate this issue but, for the sake of argument, say that no speciation has been observed to occur through a Darwinian process. Your stance seems to be that species can arise by a nonmaterial process. So for you to deny the origin of species through a Darwinian process, and for me to accept it, we both have to make a "leap of faith". A leap to the potential belief in a nonmaterial designer is a rather large leap, given the amount of evidence supporting it. My leap, that the Darwinian process that occurs within species (that you say you accept) can be extrapolated to the origin of new species, is rather small by comparison.
I think this is where we differ. You are comfortable within your scientific veracity to entertain a large leap, and I am not. The probability thing gets in my way. So it seems that you either believe in a nonmaterial designer or you have no opinion one way or the other, i.e. you are a sceptic (you still haven’t clarified this point). The latter is fine for an ultra-strict interpretation of the data or as a purely philosophical stance, but as the saying goes, if it looks like a duck and quacks like a duck, it’s probably a duck. Sorry for trying to force a label on you, but labels exist as an aid to communication and understanding. If you’re in a class of one, I still don’t understand what that class is.
November 16, 2011 at 10:16 pm #108187quote Gavin:
I really like the way you put that. Exactly my thoughts as well.
@Scottie: And if you’ve ever listened in on the debate about where to draw the line between certain species (the debate on how to classify early hominid remains for example), you’d realize that ‘species’ is really an artificial concept constructed in the human mind. Believing in evolution within a species but not believing that evolution can create new species is a weird belief. Where do draw the line? If you believe that evolution can occur within a species, why can’t that species experience enough change that we would call it a new species? I guess I’m just a little confused on your position.

November 17, 2011 at 1:39 am #108191
scottie, you have consistently stated that you will not believe something because it is
"just a hypothesis". I don’t think you realize that the first step of the scientific method is to make a hypothesis. So, according to your judgement, if every hypothesis is not worthy of consideration and false, the scientific method becomes useless?
A hypothesis (from Greek ὑπόθεσις; plural hypotheses) is a proposed explanation for a phenomenon. The term derives from the Greek, ὑποτιθέναι – hypotithenai meaning "to put under" or "to suppose". For a hypothesis to be put forward as a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used synonymously, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research.
Every theory must initially be a hypothesis. If the theory matches all the criteria necessary to be a theory, such as evidence, predictability, and consistency, then it becomes a theory. Your belief that the organisms on Earth are designed is a hypothesis as well. If it matches sufficient criteria, we will consider it a theory.

November 18, 2011 at 2:14 pm #108224
I am sorry for the delay but I have an illness in the family and I, at this moment cannot devote much time to this discussion.
I am a communications engineer (retired).
I hope, that probably will indicate I try to remain grounded in the world of what can happen or indeed is possible, in the light of our current understanding of the world around us.
My belief in the scientific method as I have explained is something I try and apply to all matters in life that require evidence to formulate opinions. I try not to have a preconceived bias when examining any matter.
That is why I am definitely not a philosopher 🙂
It is my belief in this scientific method, that has led me to accept the evidence that a only a mind can be responsible for the life processes we see all around us.
That is not to say that a mind in a material body cannot create a new species.
Craig Venter and his team have in a small way has done just that. It was his mind and that of his team that made what they accomplished possible. They did not create life itself but managed to create a new species.
What they did serves only to highlight my acceptance that a mind must be involved in the creation of species. I see no evidence that natural forces have that capability. That is why I have continued to refer to the peer reviewed papers of scientists.
I also accept that you can draw legitimate conclusions by way of circumstantial evidence.
So returning the question of Darwinism, is it a fact or is it a hypothesis.
Well it certainly is a hypothesis and indeed could reasonably be regarded as a scientific hypothesis. In fact in Darwin’s day it could have reasonably have been regarded as a null hypothesis.
I find however that the accumulating evidence opposes that hypothesis and I have tried to present that evidence.
Can I prove that a non material mind is responsible for life?
No I can’t, what I can do is to present the evidence that circumstantially draws me to that conclusion.
I did not grow up in a religious household and I don’t regard myself as a religiously inclined person. I have too much evidence around me to see the damage that organised religion has done. The same goes for organised atheism.
I don’t have any objection to organisations per se. I just always keep in mind that the evidence shows that we don’t have the capacity to successfully organise our own affairs. The thousand of years of human history demonstrates that so clearly that I regard it as a fact.
Yes I believe we are indeed partial allies.
November 18, 2011 at 5:17 pm #108230
Scottie. Thank you for making your position clear, at least to me. Amongst other labels, I consider myself an Occamist.
We mortals face two "Big Questions" – the origin of the universe (or multiverse, or whatever) and the origin of life. Evidence is totally lacking for both, so for us to have an opinion or belief about them, we have to make a leap of some magnitude or other.
For the origin of the universe, some physicists propose an extrapolation from the very small to the very large – the popping in and out of "existence" ("limits of detection" might be a better term) of virtual particles as a mechanism for the origin of the universe. I guess that’s the best we can do at present without invoking a deity of some sort. As a fellow old fart, I doubt much progress will be made on this front within my lifetime. Occam is not much help here. For the scientific method to be a valid means of accumulating data, though, it has to assume that observations are not the result of "outside" influences. The creation of the universe by a mind or from nothing are both rather bold proposals. I only prefer the latter due my inability to entertain the former.
For the origin of life, various ideas have been proposed that are testable for the mechanisms involved but not for whether or not these mechanisms actually occurred (on Earth). I doubt that any test for what actually occurred is even possible, so we will probably never find sufficiently strong evidence to favour one idea over another, although I think that in order to avoid invoking an outside influence, it would have to involve an abiotic Darwinian process (selection) of some sort. For me, a materialistic process seems more likely than a supernatural one.
For the origin of species, I can only defer to my previous argument of the magnitude of any leap that may be required. The question is not of the scale as the above two. We have pretty solid evidence that evolution occurs. Here, the extrapolation from the small to the large seems far less troublesome than what the physicists have to deal with. Occam, I think, would agree. I doubt that this leap could be the origin of your belief in some sort of cosmic mind, considering the larger issues mentioned above. I personally cannot get my head around the concept of a cosmic mind (circumstantial evidence cannot justify such a large leap), but I would choose that option over any form of a theistic god if only two options were available. But I choose the third option, just because it makes the most sense to me. The thought of a purely naturalistic, purposeless origin for everything also seems to be very comforting to me. But then I’m quite irresponsible – if there’s no cosmic purpose, then I’m off the hook for pulling my weight.quote scottie:
I don’t know about that. Without any speciation occurring, we have come a long way. You can’t possibly believe that we are no more organised today than our hunter-gatherer ancestors were a hundred thousand years ago. Biologically we may not have changed much, but culturally? Sometimes I think that you just like pulling our chains.

I’ve read the entire thread (well, maybe about 80-ish% of it… skipping Russian translations, etc…) – that was one HELL of a ride. I have NO idea how Scottie managed to withstand the pressure for so long, but I want to sincerely thank him for very interesting links, ideas and reasoning. I was also impressed by Gavin’s elegant summary.
While I’m not in the position to judge the conclusions drawn by Scottie, it was interesting to see some arguments used against Scottie’s logic (or an absence of one, in case you are in the opposite camp). At the end, it frequently rolled down to:
– Who is the designer?
– Who designed the designer?
– Why majority of scientist do not share your views?
I still fail to comprehend why it is absolutely necessary to present a complete alternative to the dominant view to be even considered being a serious debater? For 29 pages people demanded the declarations of Scottie’s alternative. What the alternative can possibly be? A Flying Spaghetti Monster, obviously. But what would’ve happened if a Flying Spaghetti Monster appeared out of the shadow – Neo would’ve been unplugged from the Matrix and got flushed down the toilet without any need to spend any time on him (hence, on my opinion, Scotties reluctance to make any official declaration on the matter). So what’s the big deal if no well shaped alternative is offered… How about denials of Dark Matter, for example? Do those scientists have to be stripped of their degrees and sent back to school for just disagreeing with the mainstream believes? They are still the scientists, right? They earned the right to have a voice.
There were a lot of legit links presented – I listened to a lot of Dawkins; let me listen to something different for a change.
And this thing – who designed the designer? According to my observations, this one is always used as a final Ace up one’s sleeve when the conversation hits the roadblock, because it supposed to send a poor Flying Spaghetti Monster into a rotating loop.
I saw a very good movie ones – Contact. There the humanity received a signal with 60,000 pages of complex data from ET life in the area of the star Vega. Nobody was able to crack it, until one guy realized what the problem was – we think like humans ( http://www.youtube.com/watch?v=2kYRvABhHAY ). We are the products of the world that we live in, and all our understanding of reality is bound by the properties of this world – a son is supposed to have a father, just like a father is supposed to have a father of his own. But is that all there is out there? If we crystallize all the knowledge that exists out there, going beyond this universe, in terms of time, space and maybe even dimensions, wouldn’t Socrates’ "I only know that I know nothing" still hold? The state sponsored religion (materialism, being that) in the country where I grew up was based on the axiom that matter has always existed, and it precedes mind. What if somehow and somewhere this concept actually works the other way around… You see what I’m sliding into? But is it really necessary, relevant or even possible to answer this question at the moment? If the mind preceded life on the planet, there should be its fingerprints left in the life itself. That’s complex enough for now, as I see it. That’s what Scottie tried to concentrate on.

Nick 7 — all 29 pages read!!! Good grief you are a sucker for punishment. 🙂
Both your comments are deserving some thought.

scottie, I’m sure you will first answer my very old question, right?quote JackBean:
you said, that 1 and 3 are wrong, so the creator "arrived" several times on Earth and worked on schifts, right? That would at least explain, why we don’t find fossils of recent animals in say Mesozoic era.

Right, they are all wrong, all the evolutionists, all IDers and all creators are wrong, but one retired engineer with no biological knowledge is right 😆
I see, you are using another anti-evo trick. Just saying, that since evolutionists argue against each other, than the evolution is wrong. Hey, they do not argue, whether evolution is true or false, but how exactly it’s occurring. With the same logic, IDers and creators are wrong, because they (with you) are arguing about the exact way, how we were created.
BTW what do you think about this video?
I guess it’s fine for you, as an engineer.

The No 2 option of yours is the nearest to my view without of course the rather silly appendage you have attached.quote :
My major point seems to have escaped your understanding.
If evolutionary theory (in all it’s various forms) is correct then there will be no disagreement between the theorists as to what the mechanism that drives macro evolution actually is.
The reality that different dissenting views not only exist but are actually competing for prominence demonstrates that the mechanism is not known.
The only common thread that unites the various adherents is that a naturalistic cause is the only one that is acceptable, regardless of where the evidence leads.
This makes any of these theories philosophically based. That is not a view I have any difficulty with, other than the point that it is regarded as a scientific fact and any dissension from that view is regarded as intolerable and therefore worthy of censorship, as you yourself have so plainly demonstrated.
The creationists also introduce their religion into their arguments and then present their views as fact.
And by the way the information I have posted comes from accredited scientific peer reviewed sources. They don’t come from a “retired engineer with no biological knowledge”. This retired engineer is only the messenger, which brings to mind the phrase “Please don’t shoot the messenger” 🙂
Gavin and Nick 7
I will respond to your posts asap.
