Re: Mitochondrial Eve a 'fact'?

Thanks for the clarification

The mitochondrial data does not support this hypothesis. In fact, it
strongly supports the alternative that modern humans arose in Africa
(the original estimate was that "eve" existed 80,000 to 250,000 years
ago

The multiregional adherants might claim that we haven't sampled every
human on earth so we don't really know the answer.

Hope their position isn't this silly.

They might also claim something like the original
mitochondrial type of the Homo erectus population that left
Africa and colonized the old world on the order of a million
years ago, was not as good in some respects to a later
version that arose in Africa around a hundred thousand years
ago and spread through all the existing human populations of
the world. There could have been mixing with indigenous
populations, but we don't see evidence of it in the maternal
lineage because all the indigenous mitochondrial types are
extinct.

I like this. (And again back to low junk rates in mDNA.)

I have an emotional preference for multiregional models (don't
know why), but have to admit the mDNA evidence is strong evidence
against, because, as I view things, selection is usually strongest
on the male side, though only slightly stronger for humans due to
pairing and relative low promiscuity.
