The Old Stone Age is the period when man was a hunter-gatherer. In this age, man’s life depended upon natural objects. He did not know about fire, so he used to eat the fruit of the trees and the flesh of animals. In order to protect himself from wild animals, he moved in groups and at night he took shelter on trees or in caves and rock shelters. He went about naked, but sometimes he wore skins of animals and leaves or bark of trees, to protect himself from extreme heat or cold. For hunting animals; he used stone weapons or branches of trees.
