Not only are the Yoruba people of Nigeria high in rh negative blood, they also carry Neanderthal DNA which is rare for Africa.

Examining the origin of rh negative blood and Neanderthal DNA within the Yoruba population may help determine the origin of rh negative blood.

According to a 2017 study, Yoruba people have ~31% prehistoric “Basal Human” (BE) admixture.

Neanderthal-derived ancestry is absent from most modern populations in sub-Saharan Africa, while Denisovan-derived ancestry is absent from modern populations in Western Eurasia and Africa. However, in Africa, archaic alleles consistent with several independent admixture events in the subcontinent have been found. It is currently unknown who these archaic African hominins were.

A model of the phylogeny of H. sapiens over the last 600,000 years (vertical axis). The horizontal axis represents geographic location; the vertical axis represents time in thousands of years ago. Homo heidelbergensis is shown as diverging into Neanderthals, Denisovans and H. sapiens. With the expansion of H. sapiens after 200 kya, Neanderthals, Denisovans and unspecified archaic African hominins are displayed as again subsumed into the H. sapiens lineage. Possible admixture events involving certain modern populations in Africa are also shown.
