Abstract: The history of North Africa is extremely complex, and it has been difficult to assess from genetic and archeological data whether early populations were replaced by later migrations or if there has been continuous settlement of the region. To resolve the history of human origin and migrations in North Africa, I have used two main forms of genetic data, the maternally inherited mtDNA and 730,000 genome-wide SNPs from a genotype array in a sample set representative of the region. I have discovered that North Africa is a mosaic of an autochthonous component dating back to the Paleolithic and at least four other ancestries, two recent ancestries from sub-Saharan Africa and the others from Europe and the Near East. We have also discovered extensive North African gene flow to the Iberian Peninsula, and minor proportions in the rest of the Europe.
