According to
David Reich, DNA analysis has shown that Western Hunter Gatherers were typically dark skinned, dark haired, and blue eyed.
[42] The dark skin was due to their
Out-of-Africa origin (all
Homo sapiens populations having had initially dark skin), while the blue eyes were the result of a variation in their OCA2 gene, which caused
iris depigmentation.
[43]
Archaeologist Graeme Warren has said that their skin color ranged from olive to black, and speculated that they may have had some regional variety of eye and hair colors.
[44] This is strikingly different from the distantly related eastern hunter-gatherers (EHG)—who have been suggested to be light-skinned, brown-eyed or blue eyed and dark-haired or light-haired.
