. "Recently, it has been proposed that E3b originated in sub-Saharan Africa and expanded into the Near East and northern Africa at the end of the Pleistocene. E3b lineages would have then been introduced from the Near East into southern Europe by immigrant farmers, during the Neolithic expansion." Also, "a Mesolithic population carrying Group III lineages with the M35/M215 mutation expanded northwards from sub-Saharan to North Africa and the Levant. The Levantine population of farmers that dispersed into Europe during and after the Neolithic carried these African Group III M35/M215 lineages, together with a cluster of Group VI lineages characterized by M172 and M201 mutations."
