First Agricultural Revolution
The first agricultural revolution was the Neolithic Revolution where humans started to farm instead of hunt. It occurred in the time period 10,000 - 2,000 B.C. Farming changed the way people lived because farmers could gather food faster, and they could have more food than if they were to hunt.
