The terminal Pleistocene and early Holocene populations of northern Africa

We studied three northern African samples of human cranial remains from the Pleistocene/Holocene boundary: Afalou-bou-Rhummel, Taforalt, and Sudanese Nubia (Jebel Sahaba and Tushka), and compared them to late Pleistocene Europeans and modern Europeans and Africans. Despite their relatively late dates, all three of our own samples exhibit the robusticity typical of late Pleistocene Homo sapiens. As far as population affinities are concerned, Taforalt is Caucasoid and closely resembles late Pleistocene Europeans, Sudanese Nubia is Negroid, and Afalou exhibits an intermediate status. Evidently the Caucasoid/Negroid transition has fluctuated north and south over time, perhaps following the changes in the distribution of climatic zones.
