We are all Africans. We originated in Africa. That is proved by the continent’s rich genetic inheritance. Africans are more diverse than the rest of humanity put together, because they are drawn from the pool of humans who did not leave. As Wells points out, two Africans from the same village could be more divergent from each other than either is from a non-African. The question is whether this new understanding will reinforce prejudices against Africans, or help end them.
