What is the difference between the Neolithic and Paleolithic age

The Neolithic period is also called the New Stone Age. It covers the period about 9000 to 3500 BC, from which archeologists have found polished stone tools, pottery, weaving, and evidence of livestock rearing, agriculture, and megaliths (huge stone constructions, such as Stonehenge). The Paleolithic period, from about 2 million BC to 10000 BC, is called the Old Stone Age. It was a time when humans used flint, stone, and bone tools, and found their food by hunting, fishing, and foraging plant foods. The Mesolithic period (sometimes called the Epipaleolithic period) took place between the end of the paleolithic and the beginning of the neolithic periods.
