I’m just curious why human couldn’t deliver their babies by themselves?? I’ve read one source and it said that it’s because that we, human have evolved by standing with two extrimities, not four extrimities (like commonly primates)…and this situation makes our cingulum pelvicum(I don’t know what the English is..:lol: ) getting smaller and make us hard to deliver our babies….
Is it true? or any different causes? 😕 - July 13, 2006 at 12:47 pm #51362herb386Participant
I’ve heard that too. I think standing on two legs means that the pelvis has much more weight to support. This means it needs to be more robust so it can’t separate so much during child birth. Passing the baby through the pelvis probably causes more damage in humans than other animals due to the tighter fit. It’s also harder due to the large size of the head compared to other animals.
Also, being social animals (with medical care) there is no selection to be able to give birth unaided.

Yeah..we’ve made our hands become free but with a lot of risks in our legs and pelvis…:lol:
so, the conclusion is :
Evolution is not a genius engineer, in fact, it’s a workshop worker..:lol: - July 15, 2006 at 10:06 am #51465Dr.SteinParticipant
I think human can make it, they just don’t like the pain, and they have money to pay the doctor. We’re getting spoiled by technology 😆

hmm…based on the magazine that I read, the coelom in human pelvic bone is getting narrower since human begins to walk with two feet..
– advantages
efficiency of energy.
free their anterior extremity.
longer move distance (helping out in moving to other continents).– disadvantages
back hurts (or other back problems).
for women, difficulity in baby delivering.
many foot problems.
a thinner cortex bone layer in certain bone at foot area (means that our bone is more spongeous than our 4 feet ancestors)…:lol: . - July 22, 2006 at 12:51 pm #51962hornetParticipant
The human female is fully capable of giving birth by herself.
However she is VERY vulnerable and if complications should arise. As they often do a doctor/midwife is good to have nearby.
So most people rush to the hospital etc when they give birth.
Just to be sure.In ancient times death was often the result of having a child.
