(The Y-Chromosome M35/215 Lineage Concordant with the Afrasian Range — The Geography of the Y-Chromosome M35/215 Lineage Which Is of Horn/East African Origin Being Largely Concordant with the Range of the Afrasian Language Family, the Distributions of the Afrasian Subfamilies and This Lineage Best Explained by Invoking Movements That Occurred Before the Emergence of Food Production as Well as After, Genetic Evidence Corroborating the Linguistic Evidence for the Horn of Africa Origin of the Afrasian Family and Its Pre-Agricultural Spread): The geography of the Y-chromosome M35/215 lineage, which is of Horn/East African origin, is largely concordant with the range of Afrasian. The distributions of the Afrasian subfamilies and this lineage can best be explained by invoking movements that occurred before the emergence of food production as well as after. This is one of the rare cases where genetic evidence cleanly corroborates the linguistic evidence. The M35/215 Y-chromosome lineage originated in the Horn of Africa — the same region that Ehret identifies as the homeland of the proto-Afrasian language on purely linguistic grounds. And the geographic distribution of this lineage matches the distribution of Afrasian languages across northeastern Africa, Egypt, the Sahara, and the Levant. The fact that the spread of this lineage requires invoking pre-agricultural movements aligns with Ehret’s argument that the earliest Afrasian expansion — the spread of grain-collecting peoples from the Horn of Africa to the Nile Valley — predated the adoption of agriculture by millennia, beginning in the seventeenth millennium BCE.
