49. If human life started in one region of Africa,

how did Neanderthals and Denisovans come about?

My guess is that some type of mutation happened and the mutants were driven out, no one bred with them. An Albino would have been a strange being in early Africa, superstition would have resulted in such people either being murdered, or if their tribe was kind, being sent out on their own. The fact that the purest White can interbred with the purest African without any issue, to me, indicates that what happened to bring about the variety of skin tones and hair textures were genetic mutations that took place over time.

Average. You missed the point. NutmegYankee Oct 2019 #57
