Mitochondrial Eve

“Mitochondrial Eve is the name given by scientists to the woman who is the matrilineal most recent common ancestor of all living humans. That means that all living humans have mitochondrial DNA derived from hers”.  Mitochondrial Eve lived in East Africa around 200,000 years ago and then spread across the globe.
