Answer:
The stone age is divided into the Paleolithic and Neolithic periods.
Explanation:
The Paleolithic period lasted about 2.7 million years ago. This period is known as the Chipped Stone Age. This is because the human beings who lived in that period began to develop tools and work instruments, using stones, which hit each other to create sharp and cutting instruments. Animal bones and teeth were also used. At that time, human beings were nomads and lived by hunting and collecting fruits and roots.
The Neolithic period is known as the period of polished stone. When the tools stopped being rudimentary and became more precise, polished and with a certain primitive technology. At that time, the agricultural revolution took place, when human beings began to stop being nomadic and started to be sedentary, staying in a single place and developing agricultural techniques for their food.
