Identify and briefly define the divisions of the Stone Age.

In Asia this gives a date of 9000--6000 BC for the Neolithic. But Europe at this time lags far behind, so a local intermediate category has been introduced -- the Mesolithic ('middle stone'), lasting from 9000 to 4000 BC and pushing the European Neolithic forward to span the period 4000 to 2500 BC.
The Palaeolithic is itself subdivided, in a manner rather confusing to the layman. Most of us, confronted with the periods Upper Palaeolithic, Middle Palaeolithic and Lower Palaeolithic, will tend to assume that Upper Palaeolithic comes first -- perhaps because we are used to that kind of sequence running down a page.
But the names relate to the layers excavated by an archaeologist, and on an archaeological site the present lies above the past. So Lower Palaeolithic is the earliest period, lasting from about 2.5 million to 250,000 years ago; Middle Palaeolithic carries on to around 40,000 years ago; and then Upper Palaeolithic to about 9000 BC.

Stone Age was a broad prehistoric period during which stone was widely used to make implements with an edge, a point, or a percussion surface. The period lasted roughly 3.4 million years[1] and ended between 8700 BCE and 2000 BCE with the advent of metalworking.[citation needed]
Stone Age artifacts include tools used by modern humans and by their predecessor species in the genus Homo, and possibly by the earlier partly contemporaneous genera Australopithecus and Paranthropus. Bone tools were used during this period as well but are 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 period in the three-age system of archaeology, which divides human technological prehistory into three periods:
