People are also so to say born prematurely, they should have been in uterus for one year more.
(and there is no physiological explanation why they are not. Those mothers who bear children longer should have had some survival advantage)
So the first year of their life they are totally dependent on their mothers and we can speak about social-uterus development. It coincides with following development of language, stance etc which cannot be reduced and compared to other primates. Human are special and on my opinion their evolution cannot be explained by evolution of primates.
Suggest that to a woman, if you dare. In particular one who has given birth.
The problem with a bigger brain is that the head also needs to be big enough to accommodate it. Let a fetus mature for a year in the womb and then try to fit that huge head through the birth canal. It simply would not fit. Sure, we could to a C-section, but how long has that been an option? (hint: "C" stands for "Caesar"). Certainly not back when we were evolving a bigger brain.
In case you still don't realize what the survival advantage of giving birth to a child with a fully grown brain, the answer is
zero. Those women would die in childbirth, leaving the baby, should it through some incredible miracle survive the ordeal, without a mother to care for it.
Rather, a human neonate has only a partially grown brain and a partially developed skull, just so it can squeeze through the birth canal -- and it's a very tight squeeze even then. The rest of the development of the brain and skull occurs after it is born. Yes, that means that it's much more dependent and unable to care for itself when it's born, but the survival advantages are very obvious (in case they are not obvious to you: bigger brain, survival of the mother, development of social structures to ensure care of the infant, development of marital bonds between the parents to also ensure care of the infant, continued nurturing of the child to full maturity).

Of course, if Dr. Mortimer's surmise should be correct and we are dealing with forces outside the ordinary laws of Nature, there is an end of our investigation. But we are bound to exhaust all other hypotheses before falling back upon this one.(Sherlock Holmes in

Gentry's case depends upon his halos remaining a mystery. Once a naturalistic explanation is discovered, his claim of a supernatural origin is washed up. So he will not give aid or support to suggestions that might resolve the mystery. Science works toward an increase in knowledge; creationism depends upon a lack of it. Science promotes the open-ended search; creationism supports giving up and looking no further. It is clear which method Gentry advocates.("Gentry's Tiny Mystery -- Unsupported by Geology" by J.
