Mitochondrial Eve is a term from genetics. It refers to a woman, whose mitochondrial DNA is the parent of all living humans. According to currrent research, Mitochondrial Eve lived about 200.000 years ago.[1] Most likely she lived in East Africa,[2] when Homo sapiens sapiens (anatomically modern humans) were developing as a population distinct from other human sub-species.

Mitochondrial Eve lived later than Homo heidelbergensis and the emergence of Homo neanderthalensis, but earlier than the out of Africa migration.[3] The dating for 'Eve' was a blow to the multiregional hypothesis, and a boost to the hypothesis that modern humans originated relatively recently in Africa and spread from there, replacing more "archaic" human populations such as Neanderthals. As a result, the latter hypothesis became dominant.
