In the Palaeolithic, people were pure hunter-gatherers. In the Neolithic they were farmers in settlements with domesticated animals and wheat, with over 100 kinds of tools and with pottery. The Mesolithic was a transitional period between the two. It happened at different times in different places. Mesolithic tools are small tools produced by chipping, and are hunter-gatherer tools, often arrowheads and points. Neolithic tools are often polished and far more varied. They are tools of more settled societies with some agriculture.
