Abstract
The Ice Age is the popular term given to the so-called Pleistocene epoch, the last of the supposed geological ages of earth history as formulated in the minds of modern historical geologists. It was immediately prior to the Recent Age in which man has left written records. Most anthropologists believe man reached the true human stage of evolution early in this glacial period, after a long process of naturalistic development from an unknown ape-like ancestor starting about 30-60 million years ago
