The Neolithic Revolution was the time in history when people first started to practice agriculture. At this point, they started to domesticate plants and animals. This changed the world forever and led to the the creation of civilizations.
The beginnings of agriculture lead to civilization in a number of ways:
- They produce more food, allowing some people to become artisans, merchants, government officials, etc -- all the things you need to have a civilization.
- They allow people to live together in dense towns and cities. These are necessary for civilization and they also cause a need for governments to keep the peace between all these unrelated people.
- They (in some places) give rise to a need for public works like irrigation projects. This also makes governments more necessary.
