Ok @Oni. If you have two parents, and four grand parents, and eight great-grand parents, and you continued this chain until the roman times - you'd have more people in your family tree then there have been people alive ever since the dawn of time. You know how it becomes possible? Incest. A lot of fucking incest. (Not that I'm saying it's a good thing...)

Well, I'm fairly sure if you calculate that, your argument doesn't hold true...
Though I see your point. Maybe if you count in that it had to be local back in the day?
