> which may have resulted in the selection of certain traits Genetics doesn't work that way. At all. 1) there weren't enough generations to change the population genetics. Bear in mind that African populations tend to have a wider range of diversity than other regions. 2) we've done a lot of population DNA studies, and they don't indicate any such differences. 3) there's no simple mapping from genes to educational ability, outside of extreme cases like genetic diseases.
