The Stone Age began about 2.6 million years ago, when researchers found the earliest evidence of humans using stone tools, and lasted until about 3,300 B.C. when the Bronze Age began. It is typically broken into three distinct periods: the Paleolithic Period, Mesolithic Period and Neolithic Period.

The Stone Age, whose origin coincides with the discovery of the oldest known stone tools, which have been dated to some 3.3 million years ago, is usually divided into three separate periods— Paleolithic Period, Mesolithic Period, and Neolithic Period —based on the degree of sophistication in the fashioning and use of tools.
