What are 6 major effects of the neolithic revolution?

The Neolithic Revolution was of high impact because it was when civilizations such as those along the Fertile Crescent first started to develop characteristics of what is considered "civilization". People who were once nomadic, meaning they moved place to place following herds to get food, were able to stay in one place for a number of reasons. They started to farm, cultivate crops, domesticate animals for their own use, etc. They even developed the system of irrigation, meaning they could move water from one place to another by a system of ditches. These people had simple technologies, such as a calendar, plows and even metal tools. As a result of all this, permanent settlements were established, creating the setup for civilization and a system of society. An advanced form of society with a class system even arose, with the Council of Elders at the top, and average citizens as the bulk of the population, being farmers, merchants, priests, and craftsmen. Overall, the Neolithic Revolution changed the way humans lived.
