It is foolish to think that any stone-age
Europeans were adapted to "extremely low
temperatures". They did not have to be.
The Gulf Stream warms the coasts, and
keeps them frost-free, even in winter,
and even in the depths of an ice age.
(Where would you chose to live if you
sought a European residence 25 kya?)
Of course, the coasts then were mostly a
long distance from those of the present day,
and the hominid sites are mostly under
about 300 feet of water. The Cro-Magnons
and the Neanderthals did not live where
their fossils are found -- even if that is the
assumption on which brain-dead PA people
routinely work.
