      I heard that the human brain has evoloved to a point where it cannot get any bigger- Thus humans will never be able to get any smarter. Is this true?

      I disagree, there are many mutations and things like that – a major reason of evolution. I believe over a long period of time (thousands of years) people will become more intelligent but this hard to determine because technology is increasing in power as well all the time.

      No I agree with Draconi, he’s right, he’s always right

      Depends if the less ‘intelligent’ people are less likely to live and reproduce than the more ‘intelligent’. Considering that we do not use intelligence to hunt or survive I think it’s unlikely. However, I guess less intelligent people might be more prone to accidents, leading to a slow removal from the gene pool.

      The darwin awards comes to mind.

      Also as James said the crucial factor is reproduction. If one looks at the statistics a very bad trend seems to be developing. The smart people(nerds) and the well educated(rich mostly) do not have many offspring. In America, we call them yuppies, they like to enjoy their adult lives without the burden of children. Whereas the uneducated(the delinquents with 6+ children) are increasing. In terms of reproductive success, the dumb and irresponsible are reproducing at a much higher rate than the intelligents.

      Lool… It seems mithril is right… Glad i am not smart:) So, i have a chance to reproduce!

      From what I remember at the moment human brains are at just the right size for processing infomation. If they get any bigger, it will take longer for messages to travle across the brain and so people will have slower reactions and wont be able to think as fast. Also it would probbly be harder to remeber things.

      Should we call this intelligence? or protection? ๐Ÿ˜‰

      This reminded me of chickadees…
      During the spring and fall the chickadeeโ€™s cerebrum part of the brain increases in size… That way they remember where they stored their food

      It is the concensus that we as a species have been around now almost 200,000 years. That means that the millions of years of primate evolution that resulted in us ended then. We have no evidence at all the people had any less intelligence then. We have no evidence of any significant biological evolution since then. Anyone who is informed about the history of feral children can more easily grasp this. People should not confuse hominid evoution with what has happened to us in the last 200,000 years. It is a very different picture and one that is abismally neglected in science. It is called social evolution.

      What is 200k years in the 4 billion years of evolution that has been happening since the beginning of life? I wouldn’t state that we’re an evolutionary dead end….not just yet.

      Evolution is a continuous process. It happens over thousands of years, and will always happen. Whether it is “foreward” or “backward” evolution, it will never stop. A species will never be able to become “as evolved as it will ever get.” The term “more evolved” does not exist in biology.

      Size of brains doesn’t have to mean more intelligent, there can also be other ways of increasing intelligence…. ๐Ÿ™‚ like i said, size doesnt ALWAYS matter

      Maybe future brains will have more myelin sheaths.
      Sorta going according to the social evolution theory a couple of posts ago—
      Humans have the power of technology…cybernetic brains would vastly improve our intellect. And as long as we have the records, this would be a trait passable down the generations.

      My reference to us showing no signs of further biological evolution in the last 1 to 2 hundred thousand years does not mean we are in a evolutionary dead end! Exactly the opposite is the case! It means that we have found a much better way to evolve and have not needed to evolve any further biologically. Social evolution is a form of evolution and it is extremely successful. That we have now populated the whole world without any further biological evolution attests to the incredible success of social evolution. Yet, the academic profession avoids the subject like the plague because to dwell on it is to find an evolutionary process that would make a sham of our secular and religious ideals.
