The Out of Africa theory, also known as the recent African origin of modern humans, proposes that all modern humans originated from a single population in Africa around 200,000 years ago. This theory suggests that Homo sapiens evolved in Africa and then migrated out of the continent to populate the rest of the world, replacing other hominid species such as Neanderthals and Denisovans.
Genetic and fossil evidence support the Out of Africa theory, showing that modern humans share a common ancestry and that the oldest fossils of anatomically modern humans have been found in Africa. This theory also explains the genetic diversity seen in modern human populations, with African populations being the most genetically diverse due to their longer history of evolution in Africa.
Overall, the Out of Africa theory is widely accepted by scientists as the most likely explanation for the origin and dispersal of modern humans.

The Out of Africa theory, also known as the Recent African origin of modern humans, or the Recent African Ancestry (RAA) theory, is the dominant scientific theory about the origin of anatomically modern humans. It posits that Africa, specifically East Africa, is the sole origin of all modern humans and that they migrated out of the continent between 60,000 and 120,000 years ago.
The theory is based on multiple lines of evidence, including genetic, fossil, archaeological, and linguistic data. Genetic studies have shown that all living humans are descended from a single population that lived in Africa around 200,000 years ago. Fossil evidence also supports the theory, with the oldest known anatomically modern human remains found in Africa. Archaeological evidence indicates that humans began migrating out of Africa around 60,000 years ago, and linguistic data suggests that the languages spoken by modern humans all originated in Africa.
The Out of Africa theory is widely accepted by scientists and has been instrumental in providing a better understanding of human evolution.
