The thing about all blue-eyed people having a common ancestor 6k-10k years ago struck me as a little odd, since I read another story maybe a year ago that said everyone living either 5k years ago or 5000 BCE (I forget which) who had any living descendants now was an ancestor of *everyone* living now.

People were arguing on Slashdot about whether that was really possible for long-isolated populations like pygmies, Native Americans and Australian aborigines. Even if it isn't, every Eurasian, North African and probably Bantu person living back then with current descendants would be an ancestor of huge swaths of the population now. (And probably every similar Native American would be an ancestor of huge numbers of current Americans.)
