A working model for the origin and formation of Proto-Afroasiatic and its later dispersal. The map is taken from:https://commons.wikimedia.org/wiki/File:World_map_geographical_(drab).png |

(2016) observed that Eurasian populations could be explained as a mixture of four sources of ancestry: Iranian Neolithic, Levantine Neolithic, East European Paleolithic and West European Paleolithic. When Taforalt [Ancient North African Iberomaurusian] people were compared to previously published ancient and modern DNA data, Upper Paleolithic North Africans can be modeled as a mixture of Natufians (Epipaleolithic populations from the Levant) and West Africans, without the contribution of Paleolithic Europe (van de Loosdrecht et al., 2018). This result suggests that Iberomaurusian populations in North Africa were related to Paleolithic people in the Levant, but also that migrations of sub-Saharan African origin reached the Maghreb during the Pleistocene. However, a preprint from Lazaridis et al. (2018) has contested this conclusion based on new evidence from Paleolithic samples from the Dzudzuana site in Georgia (25,000 years BCE). When these samples are considered in the analysis, Taforalt can be better modeled as a mixture of a Dzudzuana component and a sub-Saharan African component. They also argue that it is the Taforalt people who contributed to the genetic composition of Natufians (c.20%) and not the other way around. More evidence will be needed to determine the specific origin of the North African Upper Paleolithic populations, but the presence of an ancestral U6 lineage in the Dzudzuana people is consistent with this population being related to the back migration to Africa." Proto-language homeland regions are based on the linguistic concensus (Ehret 2004, Güldemann 2018, Gragg 2019). Afroasiatic spreaded with an ancestry on the "Ancient North African-Natufian" cline, and is generally described as "Natufian-like" in the literature; eg. largely (West-) Eurasian derived. |
