Early Homo sapiens migrations out of Africa
- Homo sapiens were present outside of Africa much earlier than previously thought, with evidence of their existence in the Levant between 90 and 120,000 years ago.
- Multiple migrations into western Asia occurred within the last four hundred thousand years, with the region being connected to Africa by a narrow strait.
- Homo sapiens remains have been found in various regions, including Greece, China, Sumatra, and the north coast of Australia, dating back to different time periods.
- Genetic evidence suggests the possibility of earlier migrations out of Africa, but this remains debated due to unsuccessful replication attempts.
- The success of Homo sapiens in expanding globally between 55 and 70,000 years ago is attributed to their advanced technology, such as bows and arrows.
