Mitochondrial Eve


Mitochondrial Eve refers to the matrilineal MRCA (most recent common ancestor). She is the woman from whom all living humans today descend, on their mother's side, and through the mothers of those mothers and so on. This goes all the way back until all lines converge on one person. One hundred percent of mitochondrial DNA (mtDNA) comes from the mother. Mitochondrial DNA is separate from regular DNA. Your mitochondrial DNA is identical to your mother, grandmother. great-grandmother, and so on, tracing back to mitochondrial eve's.

Mitochondrial Eve is estimated to have lived around 200,000 years ago, most likely in East Africa. The same mtDNA is found in the 5 main populations of the world: Africa, Asia, Europe, Australia, and New Guinea.
