What I was saying is that the cooler climates of Africa could be why we evolved and could also account for losing a lot of the hair, amongst other reasons. If there was less sun and we were dependent on vitamin D production through skin then losing hair would be an advantage. Your point about modern humans moving out of Africa helps my argument because we could not have evolved so much in that small time frame. The changes had to happen before we moved out. I don't know of any other probable reason why pre-humans would change their diet so drastically than the affects of climate change.
