Answer: population growth
Explanation:
The Neolithic Revolution, also known as the Agricultural Revolution, was a period of human evolution that began around 10,000 B.C. During this time, humans started for the very first time to establish permanent settlements where they could cultivate plants and breed animals for food, in opposition to the previous nomadic communities of hunter-gatherers. Only in this new period, population growth was possible, and eventually, it led to the development of cities.
