What does Neolithic mean?


assistant
"Neolithic" comes from the Greek word for "new stone," and it started about 10,000 years after the Upper Paleolithic. During the Neolithic, people learned how to farm. Animals that were tamed and kept as pets also gave rise to livestock. In the later stages of the Neolithic, copper, bronze, and finally iron were used to make tools. This is what is known as the "Iron Age."
