Evolution (Introduction)

It appears once again that Lamarkism is not dead. I have pointed out in previous posts that there is much evidence for adaptive changes to environment that are mediated within the organism. This abstract suports the point: http://www.nature.com/news/2009/090220/full/news.2009.113.html - One of my favorite complaints about the Darwin Theory is the issue of human childbirth. To stand on two legs requires many changes in the shape of the pelvis. Obviously newborns appear through a large opening in the middle of that female pelvis. The human brain grew rapidly especially as Neanderthal and H. sapiens appeared over 300-400,000 years. Following Darwin's approach, one must imagine that the female pelvis opening and the baby's head each had to grow in concert! And this by the hunt-and-peck approach of random mutation and natural selection, by two different individuals with different DNA (mother/ child). This could have worked only by two possible mechanisms: the simultaneous changes were coded into DNA in advance (ID) or the ability of the female human to drive genetic changes when under stress, as has been recently shown in my comments about Lemarkism.
