The document discusses life in the Neolithic Age and early cities. Key developments included the emergence of agriculture around 8000 BCE independently in various regions. Early dwellings varied by environment but included pit houses and structures made from wood, mud, and thatch. Some of the earliest cities were Jericho and Catal Huyuk, which had fortified walls and houses built closely together. After agriculture, civilization arose with specialized workers, social classes, governments, organized religion, and advanced technologies.
