Early humans like Homo habilis and Homo erectus developed tools and migrated throughout Africa and Eurasia. As humans like Homo sapiens emerged around 200,000 years ago, they began controlling fire, domesticating animals, and developing language and art. Around 12,000 years ago, the Agricultural Revolution began as humans transitioned to farming and created permanent settlements, leading to population growth and the rise of early civilizations with advanced cities, specialized workers, complex institutions, record keeping, and technology.
