A new genetic component has been uncovered in a new study:
"Our co-modeling of Epipaleolithic Natufians and Ibero-Maurusians from Taforalt confirms that the Taforalt population was mixed11, but instead of specifying gene flow from the ancestors of Natufians into the ancestors of Taforalt as originally reported, we infer gene flow in the reverse direction (into Natufians). The Neolithic population from Morocco, closely related to Taforalt17 is also consistent with being descended from the source of this gene flow, and appears to have no admixture from the Levantine Neolithic (Supplementary Information section 3). If our model is correct, Epipaleolithic Natufians trace part of their ancestry to North Africa, consistent with morphological and archaeological studies that indicate a spread of morphological features22 and artifacts from North Africa into the Near East. Such a scenario would also explain the presence of Y-chromosome haplogroup E in the Natufians and Levantine farmers6, a common link between the Levant and Africa. 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."
