Genetic Genealogy
The fact that mitochondrial DNA (mtDNA) is inherited maternally enables the matrilineal lines (or lineages) of individuals to be traced scientifically through genetic analysis, see main article, above.
Mitochondrial Eve (mt-mrca) is the name given by researchers to the woman who, by matrilineal reckoning, is the most recent common ancestor (mrca) for all living humans. She is the person from whom all mtDNA in living humans is derived.
She is believed by some to have lived about 150,000 years ago in East Africa, in or near present-day Tanzania. The time she lived is calculated scientifically, based on the molecular clock technique of correlating elapsed time with observed genetic drift, see Mitochondrial Eve.
Genetic genealogy builds upon (and helps) traditional genealogy – the latter was touched upon in the above section Matrilineal surname. For further information on genetic genealogy, or tracing of matrilineal lines via mtDNA testing, see the article Genealogical DNA test.

Famous quotes containing the word genetic:
“We cannot think of a legitimate argument why ... whites and blacks need be affected by the knowledge that an aggregate difference in measured intelligence is genetic instead of environmental.... Given a chance, each clan ... will encounter the world with confidence in its own worth and, most importantly, will be unconcerned about comparing its accomplishments line-by-line with those of any other clan. This is wise ethnocentricism.”
—Richard Herrnstein (1930–1994)
