Toward the end of the Neolithic Era, people began to use tools made from metal. Copper was the first metal used for tools. Eventually copper replaced stone, leading to the Copper Age. We will talk in class about an amazing early Copper Age discovery in the mountains near the Italian and Austrian border.
The Mesolithic period in several areas shows a gradual transition from a food-collecting to a food-producing culture. The termination of the Neolithic period is marked by such innovations as the rise of urban civilization or the introduction of metal tools or writing. Again, the criteria vary with each case. The earliest known development of Neolithic culture was in SW Asia between 8000 B.C. and 6000 B.C.
