I predicted that the Tibetans have picked up altitude adaptations from archaic sapiens, probably Denisovans.

When you predict something, particularly something surprising, and it happens, it improves the chance that your theory of how things work is correct, or close to correct.

I don't know what you think is "surprising" about the fact that archaic humans would f*ck anything on two legs, and very probably many things on four legs. That's all totally normal human stuff.

That's also the reason why modern human populations are massively mixed up with few clear boundaries, mostly clinal variation, and lots of continuous gene flow. Especially since transatlantic travel ramped up.

If you were correct about the amount of gene flow, Fst would be close to zero for every pair of populations, since that only requires a teeny amount of gene flow - on the order of 1 migrant per generation. . It's not close to zero, so you're not correct.

The amount of gene flow required to suppress local, divergent adaptation is vastly larger than that required to have near-zero Fst - and since there hasn't been enough flow to produce low Fst, there hasn't been enough to suppress local adaptation.

Which local adaptation you can see just by looking, in many cases. There are also more subtle cases of local adaptation that are not obvious by just looking.

Because humans in prehistory *really* needed to breathe the local air, eat the local food, survive the local diseases and local climate. And not a single one of them ever had to take Raven's Progressive Matrices.

Does Raven's Progressive Matrices strongly correlate with some hunting skills?

If they strongly correlated with hunting skills then hunter gatherers would have higher IQs because there would be an advantage to it in their environment (and those genes would increase as a proportion of their gene pool).

I wouldn't have found it surprising if there was a correlation, since we know our species increased its brain/skull size a lot prior to inventing agriculture.
