    Default Pleistocene North African genomes link Near Eastern and sub-Saharan African human populations



    North Africa is a key region for understanding human history, but the genetic history of its people is largely unknown. We present genomic data from seven 15,000-year-old modern humans from Morocco, attributed to the Iberomaurusian culture.We find a genetic affinity with early Holocene Near Easterners, best represented by Levantine Natufians, suggesting a pre-agricultural connection between Africa and the Near East. We do not find evidence for gene flow from Paleolithic Europeans into Late Pleistocene North Africans. The Taforalt individuals derive one third of their ancestry from sub-Saharan Africans, best approximated by a mixture of genetic components preserved in present-day West and East Africans. Thus, we provide direct evidence for genetic interactions between modern humans across Africa and Eurasia in the Pleistocene.

    Consistently, we find that all males with sufficient nuclear DNA preservation carry Y haplogroup E1b1b1a1 (M-78; table S16). This haplogroup occurs most frequently in present-day North and East African populations (18). The closely related E1b1b1b (M-123) haplogroup has been reported for Epipaleo- lithic Natufians and Pre-Pottery Neolithic Levantines (“Le- vant_N”) (16). Unsupervised genetic clustering also suggests a connection of Taforalt to the Near East. The three major components that comprise the Taforalt genomes are maxim- ized in early Holocene Levantines, East African hunter-gath- erer Hadza from north-central Tanzania, and West Africans (K = 10; Fig. 2. In contrast, present-day North Africans have smaller sub-Saharan African components with minimal Hadza-related contribution...

    Makes sense they were around 1/3 SSA before neolithic, it's roughly divided by 2 today, which confirms the estimation in a previous study that they got 40-50% neolithic through Iberia. And of course they didn't find any paleo/meso type of Euro input yet at that time since it came embedded with the neolithic later. Modern N.Africans are even exactly between Euro Neo and the Taforalt samples on the pca.

    Also explains why they often get a mix of East and West African in various calculators, instead of just W.Africa.

    did they not also recieve natufian input from the levant?

    So Horners are the native people of North Africa?
