Chart of genetic evidence of autosomal DNA in maghrebis

Recent genetic analysis of North African populations have found that, despite the complex admixture genetic background, there is an autochthonous genomic component which is likely derived from "back-to-Africa" gene flow older than 12,000 years ago (ya) (i.e., prior to the Neolithic migrations). This local population substratum seems to represent a genetic discontinuity with the earliest modern human settlers of North Africa (those with the Aterian industry) given the estimated ancestry is younger than 40,000 years ago. North Morocco, Libya and Egypt carry high proportions of European and Near Eastern ancestral components, whereas Tunisia and Saharawi are those populations with highest autochthonous North African component.

Reference 2: Algeria, Tunisia, Saharawi, Morocco North, Morocco South, Libya and Egypt.
