Question

Why do humans of European ancestry have small percentages of Neanderthal DNA in their genomes while humans of African ancestry do not?

Answer 1

Around then of relocation very nearly 70,000 years back, no less than two types of primate cousins strolled the Eurasian landmass—Neanderthals and Denisovans. As our advanced human progenitors relocated through Eurasia, they experienced the Neanderthals and interbred. Along these lines, a little measure of Neanderthal DNA was brought into the cutting edge human gene pool.

Everybody living outside of Africa today has a little measure of Neanderthal in them, conveyed as a living relic of these antiquated experiences.

A group of researchers looking at the full genomes of the two species inferred that most Europeans and Asians have around 2 percent Neanderthal DNA. While, Indigenous sub-Saharan Africans have none, or next to no Neanderthal DNA in light of the fact that their predecessors did not relocate through Eurasia.
