Homo erectus: First Migration Out of Africa

Between 1.8 and 1.7 million years ago, Homo erectus became the first hominin species to leave Africa. Archaeological evidence from Dmanisi in Georgia (dated to approximately 1.8 million years ago) and sites in China and Indonesia (dated to approximately 1.7 million years ago) document this dispersal. These early humans possessed bipedal locomotion, larger brains than predecessors, and Oldowan stone technology. Evidence suggests the migration followed water sources and animal herds through southern and eastern routes via the Levantine corridor. This expansion established human presence across Eurasia and led to the development of regional populations.
