Answer: Farms
Explanation: Before the so-called agricultural or Neolithic revolution, people in smaller nomadic groups moved from place to place for hunting and gathering wild plants for food. When the resources for hunting and collecting wild plants disappeared for various reasons, the nomads moved further in search of food. The agricultural revolution happened when, according to some scientists, advances in the human brain occurred, and people began to make farms where they grew the plants and livestock needed for food, clothing and life in general. According to some other scientific theories, the reason for permanent settlement and farming was global warming. Thus, the periods of beginning of agriculture and permanent settlement vary from region to region.
