“For modern humans, that number has reached one: each of us can trace our mitochondrial lineage to a single human female who existed in Africa about two hundred thousand years ago. She is the common mother of our species. We do not know what she looked like, although her closest modern-day relatives are women of the San tribe from Botswana or Namibia. I find the idea of such a founding mother endlessly mesmerizing. In human genetics, she is known by a beautiful name – Mitochondrial Eve.”
