Epicanthic folds occur among East Asians, Southeast Asians, Central Asians and some South Asians, Indigenous Americans, the Khoisan, Inuit, and occasionally among Nilotes,[6] and non-Indo-Europeans[disambiguation needed] (e.g. Sami, Finns, and Hungarians).[7][8][9]

I forgot the term, but you will know:
It is a bump on the back of the skulls of Bering straight crossers, that is not present in Caucasians.
Native Americans possess this bump.
Apparently Kennewick Man did not have this bump.
Do you know the term? It escapes me. It is not related to phrenology.
