It not only made settlements possible—and ultimately the building of cities—but it also made available a reliable food supply.
Farming was indeed a revolutionary discovery. It not only made settlements possible—and ultimately the building of cities—but it also made available a reliable food supply. With more food available, more people could be fed. Populations therefore increased. The growing number of people available for more kinds of work led to the development of more complex social structures. With a food surplus, a community could support a variety of workers who were not farmers. The agricultural revolution thus resulted in a division of labor, with some people farming, while others worked at various crafts, such as making pottery, cloth, or tools. Craftspeople traded the goods they made to farmers for food.
