Africa is very, very, very genetically diverse compared to the rest of the world. I don't think there exists a population which doesn't contain genes for lighter skin. I think race labels make some sense in a social/cultural context: In America we can call someone "black" when they are 75+% white, because for their entire childhood/life, socially, society at large treated them similarly as they treat people who are "100% black". But race doesn't make sense in a genetic context. It's probably far more absurd than defining the difference between an accent vs dialect vs language. Even though there are clear differences between individuals/families, the boundaries are absolutely arbitrary.
