The Stone Age is a broad prehistoric period during which stone was widely used in the manufacture of implements with a sharp edge, a point, or a percussion surface. The period lasted roughly 2.5 million years, and ended between 4500 BCE to 2000 BCE with the advent of metalworking. Stone Age artifacts include tools used by humans and by their predecessor species in the genus Homo, as well as the earlier partly contemporaneous genera Australopithecus and Paranthropus. Bone tools were used during this period as well, but are more rarely preserved in the archaeological record. The Stone Age is further subdivided by the types of stone tools in use.
The Stone Age is the first of the three-age system of archaeology, which divides human technological prehistory into three periods:
The Stone Age is nearly contemporaneous with the evolution of the genus Homo, the only exception possibly being at the very beginning, when species prior to Homo may have manufactured tools. According to the age and location of the current evidence, the cradle of the genus is the East African Rift System, especially toward the north in Ethiopia, where it is bordered by grasslands. The closest relative among the other living Primates, the genus Pan, represents a branch that continued on in the deep forest, where the primates evolved. The rift served as a conduit for movement into southern Africa and also north down the Nile into North Africa and through the continuation of the rift in the Levant to the vast grasslands of Asia.
