... Eve The postulated female ancestor of all modern humans, who was an archaic human living in Africa about 140 000 to 280 000 years ago, based on studies of mitochondrial-DNA from modern populations by a team led by Allan Wilson . The data suggest there may have been a bottleneck associated with the speciation event leading to Homo sapiens . See also adam...

...mitochondrial Eve The hypothetical female claimed by some biologists to be the most recent ancestor of all living humans. Analysis of mitochondrial DNA (mtDNA) from groups of people throughout the world suggests that mitochondrial Eve lived between about 100  000 and 148  000 years ago, probably in Africa (hence she is also known as ‘African Eve’). Mitochondrial DNA is particularly useful for investigating recent genetic history as it mutates quickly (ten times more rapidly than nuclear DNA) and in humans is inherited solely through the female line...

...Mitochondrial Eve The populist name for the woman thought to be the most recent common matrilineal ancestor of all living humans, who was one of a population living ~150 000 years ago that gave rise to multiple lineages, only one of which remains. The supposition depends upon all mitochondria deriving from the egg, and there is some evidence that this may not be correct....

The hypothesis (based on study of mitochondrial DNA) that modern humans have a common female ancestor who lived in Africa around 200,000 years ago.

...of the entire mitochondrial genomes from three humans (one each from Africa, Japan, and Europe) and four apes (a chimpanzee, a bonobo, a gorilla, and an orangutan) resulted in the estimate of 143,000 years as the time for the origin of the ancestral human mtDNA, again in Africa. In the popular press, the woman with this ancestral mtDNA is sometimes called “African Eve” or “mitochondrial Eve.” Mitochondrial Eve is our most recent common ancestor in the purely female line. Other women were contemporaries of Eve, but their mitochondria have not been retained,...

...the popular press this male was called Y chromosome Adam . The observation that this man lived thousands of years later than mitochondrial Eve simply means that at the time Eve’s mtDNA had become fixed in Homo sapiens , males still had a variety of Y-chromosomal DNAs. It took tens of thousands of years more before one particular version of the Y became fixed in our species. See Appendix C , 2000, Underhill et al. ; mitochondrial DNA lineages...

... African, Eve (c. 200,000 years before present) , conjectural early human, also known as Mitochondrial Eve, was proposed by Rebecca L. Cann and her fellow researchers in 1987 . Using mitochondrial DNA (inherited only along the maternal line), Cann and her associates examined 147 individuals and produced a genetic evolutionary tree showing branching from two sets of individuals: one set of African ancestry and a second set of mixed African and “other” ancestry. The most parsimonious explanation of the tree was that modern humans originated in Africa from...

...accumulated, apparently at a fairly constant rate, in the mitochondrial DNA of people from around the world have been used to trace the prehistoric migrations of populations from the emergence of Homo sapiens in Africa about 150,000 years ago. Mitochondrial DNA is also used in genetic fingerprinting when nuclear DNA cannot be extracted in sufficient quantity, as often occurs when DNA is taken from solid bone, tooth fragments, hair, or faeces, rather than from blood, saliva, or semen.
