Answer 2

CULTURAL EPOCH, some of the most dramatic environmental change on Earth, excepting asteroid impacts, is caused by the climate. Not least, glacial cycling drove biological evolution on our planet for eons and cultural evolution more recently. Harsh climate ~30,000 years ago, in fact, may have been the reason the Cro-Magnons replaced the Neandertals; the former had mastered the technical skills needed to survive at the height of the most recent ice age.
