Perhaps you have noted that this lack of mixing already results in the
production of pseudo-speciation in humans. For example, it is not possible
to produce viable offspring between some sets of Nordic women and Australian
aboriginal men. Doesn't happen a lot in practice anyway. I don't see any
reason why the same should be untrue for neanderthal, or take your pick of
any other group really.

I agree about the general point though:
N down, [(2^N)-N] to go...congratulations.

Cheers,

Gregg
P.S. Last I checked, the only aboriginal member of the Australian parliament
was a BONNER. Pretty interesting, n'estcafe?

I agree, migration patterns are indeed fascinating but which ancestor is
that one in a personal genealogical sense? My calculator is not capable
of calculating the number of ancestors one would have even 1000
generations ago. Just going back to the time of Christ one might have
about 10^30 grandparents give or take a million or so.

I wonder if any of us were to be so isolated that there was no mixing
for 20-30,000 years whether we'd even be able to reproduce or would our
mutation differences be so great that we'd actually become another
species like perhaps the Neanderthal?
