Darwinian view of human birth (Introduction)

Our birth canal is twisted, Birthing is painful, all because of the skeletal changes in the pelvis with the appearance of upright posture, and the enlargement of the brain. We still have no idea which of our grandfather forms arranged for all this. The fossils are not complte enough. And no one has an answer for the problem of how the mothers with one type of DNA arranged to enlarge the pelvic outlet while the babies, with a different DNA, grew bigger heads. How was that coordinated? Coordinated or there would not have been any live babies.:-http://www.scientificamerican.com/article.cfm?id=invention-of-childhood-why-it-hurt-have-baby&page=2-"We humans, however, wait an average of nineteen years before bearing our first child. Why? If shortening the time between being born and bearing as many offspring as often as possible works so well for other mammals, for what reasons would evolution twist itself backward with Africa's struggling troops of savanna apes? Why bring increasingly defenseless infants into the world? Why expose their parents to greater danger to feed and protect them? Why insert this extra, unprecedented cycle of growth, this thing we call childhood, into a life—a time when we rely utterly on other adults to take care of us? And what advantage is there in taking nearly two decades to bring the first of the next generation into the fold?"-Yes, why? unless planned. It doesn't fit Darwin's theory of responding to challenge. The change created more challenges than were present for the original organisms!

Another comment on human birth and the problems related to it because of the pelvis shape from upright posture. A book review:-http://online.wsj.com/article/SB10001424127887324348504578608253826802978.html
