What percentage of a person's ancestors, going back 100,000 years (when people lived in kin groups), mated with their cousins, siblings, or other relatives?

All kidding aside, even just the past two hundred years in some parts of the country (not talking about deep south either) marriages between cousins was common - there wasn't exactly a large pool of potential mates to choose from in many small towns until this past century. I'm sure everybody has had a few kissin' cousins in their past.

It's interesting that Darwin, of all people, married his first cousin, Emma Wedgewood. She was quite rich (from the Wedgewood pottery family), so it probably had something to do with survival of the fittest.

Bingo! When I was growing up in a small Southern community, it always bugged the heck out of me that the best looking women were always my cousins.
