The hypothesis that anatomically modern Homo sapiens evolved in Africa and later spread to other parts of the world is called:
Out of Africa (replacement) hypothesis
The Out of Africa hypothesis, also called the replacement model, proposes that anatomically modern Homo sapiens originated in Africa around 200,000 years ago and subsequently migrated outward, replacing earlier hominin populations in other regions.
This is supported by genetic and fossil evidence showing the greatest human genetic diversity within African populations, consistent with Africa being the origin point.
Punctuated equilibrium describes a pattern of evolutionary change with long periods of stability interrupted by rapid change, the multiregional hypothesis proposes independent parallel evolution of modern humans across different continents, and the founder effect describes genetic drift in a small colonising population, none of which describe this specific migration hypothesis.
Therefore, this hypothesis is called the Out of Africa (replacement) hypothesis.
