One important point to consider is that the first Eoropean Homo

of the immmigrants from Asia is a good guess for both.

 Disease can/could certainly be a factor. LeBlanc makes
the observation that populations tended to be too small
and dispersed (i.e., low density) such that anything
like an epidemic was not likely. So postulating
disease impacts like that may not be tenable without
better evidence. He (LeBlanc)relates that archaeological
and historical evidence show warfare/fighting death
rates were like 25% of adult males over their adult
lives and up to 5% of women (not to mention children).
He appears to be citing Keeley's 1996 "War Before
Civilization". (that's always been on my list-to-get
but never very high - til now ;)

It's a dumb premise to start with, this idea that they
were wiped out.

The story is false. The original study used African Americans
as their "African" population. Of course there was CENTURIES
on interbreeding between white Europeans and black African
slaves in America, yet they used African Americans as their
African subjects. Wow. AND their findings held when the
work was later repeated using African subjects!
I argue against how they interpreted their finding but, what
is important here is that everything you are saying here,
everything you are replying to is based on the exact opposite
assumption of the original study, and that original study was
upheld by a later study.
Get?  The original "Out of Africa/Eve II" study assumed that
African American subjects could be used in place of people
in Africa, as their African representatives, despite centuries
of interbreeding, and the claim is that this assumption was
upheld. The study was repeated and the findings upheld.
You are "Arguing" the exact opposite.
