The early stone age was the early time of the stone age. The human beings at this period used to live by hunting animals for food. But for hunting, they used some tools made up of stone, flint, bone, and antler. They also used to gather wild berries, nuts, and fruits from the trees available. They learned to use the animals for some of the other purposes. Both human beings and animals used to travel long distances in search of food, and hence never used to stay at the same place for long.
