No, I'm not pointing to specific places IN COMMON to both.
I'm simply pointing to a common problem ....

that is, how do we be SURE that finding a given haplogroup/haplotype
in two places, in one place it being common and one place it being
rare, means it started in the place where it was common? It could
have started in some place in between, and it just so happens that
the people who moved one way managed to become dominant.

You can answer "look at diversity of haplotypes" but I find that
unconvincing if the populations are small overall, as are
the ones of the Altai/Norway/McDonald R1a people.
