In the final episode of the re-imagined Battlestar Galactica series, the human-Cylon hybrid child Hera is revealed to be Mitochondrial Eve (the woman from whom all living humans today descend, on their mother's side).

And that all human lineages--both aboriginal and colonial--that did not produce a female child who is a descendant of hers went extinct?
