"Moreover, our model predicts that West Africans (represented by Yoruba) had 12.5±1.1% ancestry from a Taforalt-related group rather than Taforalt having ancestry from an unknown Sub-Saharan African source11; this may have mediated the limited Neanderthal admixture present in West Africans23. An advantage of our model is that it allows for a local North African component in the ancestry of Taforalt, rather than deriving them exclusively from Levantine and Sub-Saharan sources."
