OK, but take the Andean's great-to-the-nth grandmother from 7300 years ago (one of the ones who lived in the same region all those centuries ago). Is that grandmother also an ancestor of the teacher in Somerset? And of some villager in a remote village in Tibet?

Weren't, for example, Native Americans, isolated from Europe for more than 7,300 years?

So if you consider someone living in the Andes with pure Native American ancestry, how are they descended from Cheddar Man?
