I come from a long line of inbreeders. No more laughing at them there bills from the hills! It seems all us white folk are related to only 50 frisky ancestors!

Geez, I can't believe I'm related to all these people. Ugh.

50 ancestors? What utter nonsense!

In 60,000 years with an average generation time of 25 years that's 2,400 generations. I would have had 2^2400 ancestors alive back then.

That's 30 billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion billion ancestors, Bud, don't try and tell me any of those were inbreeders!

wantwit, you could point those Bible-toting biologists to Steven Den Beste's essay on Noah's Y Chromosome.

This explains why we (white people) all look alike....

lia, sounds like a bottleneck effect to me. population genetics and all that.

That's right! Since each of us had*two* parents, the human population must be shrinking by half each generation. At this rate it won't be long before there's only one single individual left alive. (Like it or not, that individual will be at least one third Chinese.)

Genetics be damned, we got**serious** problems with the arrow of time here.

I'm having a bit of trouble working it out, but is 50 people really that much of a worry? I'm thinking that if you planned properly, you could avoid any breeding that was closer than fourth cousins. I don't think I'm conceptualizing the problem very well, however, and while I could work it out in time, there must be someone here who knows offhand.

All they've done is identify (or claim to identify) a small founder population. Europe hasn't been in a plastic bag since paleolithic times; there's been**lots** of population exchange and outbreeding since then.

fullers right. there's evidence of cross migrations (of humanoids) ... i suppose the idea is if "people" traveled from africa to europe and the americas what would keep people from going back?

Of course this makes sense, any Bible-toting biologist will say, view adam and eve as the male and female isolated population of these 50 ancestors of you and i. The founder effect at its best?
