Why did early humans begin to set up permanent villages?

I hope this answers your question

Explanation:

Sometime about 10,000 years ago, the earliest farmers put down their roots—literally and figuratively. Agriculture opened the door to (theoretically) stable food supplies, and it let hunter-gatherers build permanent dwellings that eventually morphed into complex societies in many parts of the world.Mar 27, 2017
