I thought my nilote blood
Nilote is different from West-African, abowe. Current Nilo-Saharans have some notable West-African admixture (5-30%+) but the ancient "Nilotes" we are descended from lacked this admixture by the looks of it and though the "West-African" component itself seems mixed with something "East-African/Nilote" itself, the time-divergences I've seen in papers would suggest our SSA side hasn't shared ancestry with theirs in some cases as far back as 30,000 years or more from what I remember. I think as more ancient DNA comes out and we break down these components those numbers will go down but you get the gist, that is a pretty deep divergence by Human standards. Well in the ball-park of Europeans Vs. East-Asians.
But for reals, Humans in general are closely related species. Believe it or not, Chimpanzees in Africa (a single continent) have more genetic distance between them than our entire species, and by a lot.
