So where did whites come from? Spontaneous albinism? It’s just an amusing observation of mine that whites were alien to Africans when they ‘rediscovered Africa’...there’s probably some basis of fact to this, but who would actually fund a study of ancient reverse racism? A study that almost certainly would conclude that whites were cast out of Africa, not ‘migrated’...likely demonstrating that racism is rooted in those of color, not the converse.

One possibility is that humans out of Africa interbred with the Neanderthals who were already in Europe/Asia, producing the white and oriental races.

With the invention of agriculture, probably in Mesopotamia, white agriculturalists probably expanded out from there, finally arriving at the rich farming environment of the Nile.

There are many scientist who believe exactly what you have written as well. I think it is very conceivable that mating with Neanderthals was fairly common.
