So on that graph, the distance between East and West Africans is about as great as the distance between Indians and Europeans. Somalis are closer to East Asians than they are to Southern African Khoisan people. Bedouin Arabs and Southern Europeans are closer to each other than either are to North Africans or Northern Europeans.

There are certainly some cases where the genetic data matches conventional thinking about race, but also many where they flatly contradict. It also suggests that saying something like "white people are genetically smarter on average than black people" is highly suspect. The group of people that we call "black" has a greater range of genetic profiles than the rest of the world put together, and the group we call "white" is kind of confused—to be genetically meaningful it would probably need to either include North Africans and Arabs or exclude Southern Europeans.
