Description
DE is the ancestor of haplogroups D and E. Haplogroup D is found mainly in East Asia (Japan, Tibet) and the Andaman Islands, while haplogroup E is the predominant Y-DNA lineage in Africa. The DE ancestor may have lived in Africa or may represent an early out-of-Africa movement that partially returned. DE and its descendants represent some of the deepest human patrilineal lineages outside haplogroup A.
Interesting Fact
Haplogroup D is found at high frequencies in Japan (35–40%) and among Tibetans (~50%), while its sibling branch E dominates sub-Saharan Africa. This dramatic geographic separation from a single ancestor reflects ancient migration patterns during the Upper Paleolithic.
