These last couple of days have been almost the same as the average
temperatures during the last ice age. Can you imagine, with winter
weather typically lasting ten months each year.
Neanderthals
went extinct during the final dip of the ice age, 25,000 years ago. The
last of them huddled in caves in Gibraltar, at the southern most tip of
Spain. Cro-Magnon (homo sapiens) spread to cover Spain thereafter, but
could not go further north because all the fertile fields and forests of
France were arctic tundra.
What was the difference? Perhaps
the bone needle allowing Cro-magnons to tailor skins to fit limbs in
layers and add differing skins to prevent frost bite to the face. These
skills are practiced by the Inuit today in the Arctic.
