Early humans lived as hunter-gatherers but around 10,000 years ago began migrating and adapting to their environments. Some groups began farming and domesticating animals, leading to the Agricultural Revolution and the development of permanent settlements and villages. As agriculture techniques improved, villages grew in size and complexity with specialized workers, trade, and early forms of government. One such complex village was Catal Huyuk in Turkey, home to 8,000 people with varied occupations and cultural practices like wall murals and burying the dead under house floors.
