The Paleolithic Age is also known as the Stone Age. It is called the Stone Age because it was the first time in history that stone tools were used.
The Paleolithic Age began with the development of stone tools, and it ended with the development of agriculture. Neanderthals walked the earth in the middle of the period. However, by the end of the Paleolithic age, Homo Sapiens had evolved and had begun to emigrate from East Africa. Art also developed during this period. Rock paintings and crude musical instruments from the time period are evidence of art development during the Stone Age.
