You asked (paraphrasing) where did the various colors come from? If you did not mean different colors then use different words. I am ***uming that all of the ones that you mentioned did not happen all at once so there had to be a 'first' humanoid not likely a whole tribe at once - you seemed to have an angle you were working so I asked what was the color of the first humanoid? If a cosmic ray hitting a gene makes a mutation in a primate, we finally arrive at humans and we do not see the phenotypical characteristics in primates that we see in the 'blacks, whites and yellows' (What? no Red man?
) I think it is safe to ***ume that all humans started with one color phenotype. Which do you suppose it was? Like I said, just curious.
