Age confirmed for 'Eve,' mother of all humans

Mitochondrial DNA places her existence at about 200,000 years ago

A maternal ancestor to all living humans called mitochondrial Eve likely lived about 200,000 years ago, at roughly the same time anatomically modern humans are believed to have emerged, a new review study confirms.

The results are based on analyses of mitochondrial DNA. Found in the energy-producing centers of cells, mitochondrial DNA is only passed down the maternal line, and can be traced back to one woman.
