Answer:
Neolithic Revolution.
Explanation:
The Neolithic Revolution is a term that refers to the transformation of ancient civilizations from hunter-gatherer societies to societies where people made a living mainly through agriculture and animal husbandry. This is also the change that marked the transition between the older and younger Stone Age. The oldest traces of grain cultivation and animal husbandry are about 11,000 years old, and come from Southwest Asia (the fertile crescent), but an independent development towards agriculture also took place in Central America and China. The term "the Neolithic revolution" refers to the great effect this change had on the organization of the societies that began to cultivate instead of living as hunters and gatherers.
