Mitochondrial Eve (mt-mrca) is the name given by researchers to the woman who is defined as the matrilineal most recent common ancestor (MRCA) for all currently living humans. Passed down from mother to offspring, her mitochondrial DNA (mtDNA) is now found in all living humans: every mtDNA in every living person is derived from hers. Mitochondrial Eve is the female counterpart of Y-chromosomal Adam, the patrilineal most recent common ancestor, although they lived at different times. She is believed to have lived about 170,000 years ago, or roughly 8,000 generations ago. This places her in a period significantly earlier than the out of Africa migration some 60,000 years ago, and close to the first appearance of archaic Homo sapiens itself, roughly contemporary to early fossil evidence found in Ethiopia, such as the Omo remains or the Homo sapiens idaltu fossils. Since Mitochondrial Eve is assumed to have lived in Africa she is sometimes also referred to as African Eve.
