Scientists have located a gene in some sub-Saharan Africans that governs salvia consistency, which is absent from other modern humans (in and out of Africa), form Neanderthals and from Denisovans.
Given the extent to which it is divergent, the most likely explanation, which supported by other previous research indicating genetic traces of archaic admixture in Africans, is that the ancestors of the people who bear this gene had children with to be determined archaic hominin species in Africa. But, since we have no ancient DNA from any archaic hominin species in Africa, it is hard to know which archaic hominin species introgressed into the modern human genome in Africa.
