Description
E is the dominant Y-DNA haplogroup in Africa, found in over 80% of sub-Saharan African men. It split into two major branches: E1b1a, which is the characteristic haplogroup of West, Central, and South Africa and was carried into the Americas via the transatlantic slave trade, and E1b1b, which is strongly associated with Afroasiatic-speaking populations of North Africa, the Horn of Africa, and Southern Europe. The spread of E1b1a is closely linked to the Niger-Congo (Bantu) language expansion across sub-Saharan Africa, while E1b1b tracks the dispersal of Afroasiatic speakers including Cushitic, Berber, and Semitic populations.
Interesting Fact
E1b1a is the most common haplogroup among African Americans (~60%), directly reflecting the transatlantic slave trade routes from West and Central Africa — making haplogroup E a living genetic record of one of history's largest forced migrations.
