Stone Age
The age when the prehistoric man began to use stones for utilitarian purpose is termed as the Stone Age. The Stone Age is divided into three broad divisions ? Paleolithic Age or the Old Stone Age ( from unknown till 8000 BC), Mesolithic Age or the Middle Stone Age (8000 BC ? 4000 BC) and the Neolithic Age or the New Stone Age (4000 BC ? 2500 BC) on the basis of the stone tools, which were made during that time.
