Study Notes
- The Out of Africa Theory proposes that all modern humans originated in Africa and migrated to other parts of the world.
- Evidence supporting the Out of Africa Theory includes genetic evidence showing a common ancestor 200,000 years ago in Africa, linguistic evidence tracing all human languages back to Africa, and fossil evidence of early human species originating in Africa.
- The first migration Out of Africa occurred around 100,000 years ago, spreading to the Middle East, Asia, and Australia.
- A timeline of human migration shows the emergence of a common ancestor in Africa 200,000 years ago, with subsequent migrations to different parts of the world over time.
- Modern human populations continue to spread globally, leading to genetic diversity within Africa and decreasing genetic diversity outside of Africa.
- The Out of Africa Theory explains why early human fossils are primarily found in Africa, indicating that Africa was likely the birthplace of humanity.
- An alternative hypothesis, the multi-regional hypothesis, suggests human evolution occurred in multiple regions and interbreeding led to homogeneity, but this is not widely accepted due to lack of supporting evidence.
