Out of Africa theory

The Out of Africa theory is the idea that modern humans (Homo sapiens) originated in Africa and then migrated to other parts of the world. This theory suggests that around 200,000 to 300,000 years ago, early humans left Africa and spread to Asia, Europe, and eventually to the Americas and Oceania. Genetic and fossil evidence supports this theory, indicating that all non-African populations share a common ancestry that can be traced back to Africa. This explains the genetic diversity we see today and highlights the African continent's central role in human evolution.
