(25,699 posts)"Race" as understood today is a very recent (in terms of history) political construct with its origins in the anglo-American slave trade. As such it is very much post-neanderthal.
What's more, that "1-3%" of the genes amounts to pretty much nothing but a few mitochondrial markers. We're not Jedi, the origins of our mitochondria isn't especially important to the way we function. And if it did, well, we'd have to wonder about Fijians and their 6% denisovan DNA.
Third, the division isn't really "white" and "black," but rather between Eurasians and Africans. Eurasians (Including native Americans) who went north from the Indian basin bumped into (and bumped with) neandertals and Denisovans; some groups did both. Which leads us to the next point...
There was a lot of fucking going on between then and now. Like seriously, that's several thousand generations of people. And if you know anything about humans, we like to travel as much as we like to fuck. Those Eurasian Mixer genes came back to Africa at many times in human history. There wasn't a lot of spread beyond northern and eastern Africa - 'cause those were the primary points of contact and there are some real geographic barriers involves. And to be truly aware, you gotta realize that modern humans were busy "incorporating" the last remains of ergaster and rhodesiensis into their genome before leaving Africa.
