In an agricultural society like that of the modern world, it takes fewer people to produce food than in hunter-gatherer societies, and agricultural societies tend to be about 25% larger than hunter-gatherer societies. Farming changed everything for humans, and no innovation in human history, with the exception of fire, did more to alter the course of human development than what is called the Agricultural or Neolithic Revolution. the development of agriculture—the Neolithic Revolution—changed human speech and gave birth to stratified societies, technological changes, and social and cultural organization that radically altered what it meant to be human. Larger human settlements coincided with the rise of animal domestication and agriculture. People seem to have begun by domesticating dogs for hunting, and then sheep, goats, and cattle for agriculture, which could replace hunting. Humans learned how to grow wheat and barley, and then beans.
