The study of HER2-OCA2 genes (which determine depigmentation of skin,blond hair & blue eyes),of Neanderthal derivation, allowed determination of 4 genetic alleles, which correspond to the spread of Neanderthals(1),Cro Magnon(2),Denisova(3)and Red Deer Cave man(4).Continue below👇

In African hominids this gene is not present, which is specific to Western Erasian hominids, 100% in Neanderthals and partially in CroMagnon and Denisova (in East Asians it is present only in white skin not in eyes and hair). 👉👉

In Americas,considering only Native populations preceding Columbus, we can see that genetically they are mainly Denisovians, with the presence of archaic Neanderthalian and CroMagnon traces, and subsequently Eastern Asiatic, due to subsequent migrations. 👉
