According to a new preprint by Durvasula and Sankararaman (D+S):
Using this method, we find that ~7.97±0.6% of the genetic ancestry from the West African Yoruba population traces its origin to an unidentified, archaic population
This ~8% matches well the ~9% of "West Africa A" in Yoruba of the model of Skoglund et al. Figure 3D. If "West Africa A" corresponds to the Archaic Ghost of D+S, then the Mende have the most of it at ~13%.
I have long maintained that the higher genetic diversity of extant Sub-Saharan Africans is the result of admixture between "Afrasians" (a population that spawned Eurasians and much of the ancestry of Sub-Saharans and which had "low" (Eurasian-level) of genetic diversity) and multiple layers of "Palaeoafricans". It would seem that one such layer has now been discovered.
