Early humans learned important skills during the Stone Age that enabled the development of modern civilization, including learning how to farm, communicate, and cook. Farming allowed people to stay in one place and grow food instead of constantly moving, allowing the formation of permanent villages and eventually cities. Developing language facilitated communication between groups and eventually led to modern communication technologies. Learning to cook food provided health benefits by killing bacteria and expanded what foods were available, laying the foundation for today's variety of prepared dishes.
