Fair call but Eskimos / Inuit have evolved this squat body shape, even
with clothing, so I would expect that early European moderns in similar
climates would also evolve the same way.

As to HSN athletic ability, they were apparently able to survive for
200KY on a 90%+ meat diet with hunting techniques akin to rodeo

been selected to retain their Neanderthal features than their
