mitochondrial eve

Cultural Dictionary

mitochondrial Eve definition


When the original analysis of the DNA in the mitochondria of modern humans was carried out, the results suggested that all modern humans share the DNA of a single individual female who lived a few hundred thousand years ago. This female was named Eve in reference to the Creation story in the Book of Genesis in the Bible.

Note: Further research has largely discredited the notion of a single Eve, although scientists have found that modern humans are descended from a very small population, perhaps as few as five thousand individuals.
