What I can say for certain is that, ironically, almost everybody has gotten backwards the political logic of out-of-Africa. The conventional wisdom is that giving Africa geographic pride of place in human evolutionary history proves the genetic equality of Africans and Eurasians. In reality, the out-of-Africa theory implies that the main racial gap in humanity is between Africans and everybody else, which is not what you are supposed to believe (although many Americans today act, not unreasonably, as if they do believe it and kind of like it).
