africans, ignoring the skin colour, actually have the most genetic diversity imaginable. There's so many distinct ethnic groups, and you can often as not tell by appearance esp the shape of the head, where they are from and stuff (not throwing shade here, it's obvious to anyone when you have seen enough people from certain regions), and naturally other featuress vary as well. so kenyans are good endurance athletes, no question, but not as many of them have massive natural ability at say powerlifting. and so on
