The Replacement model asserts that there was a single origin of Homo sapiens in Africa and that these anatomically modern humans migrated out from Africa and replaced all other less evolved humans throughout Europe and Asia - hence the name, Replacement model.

With the official definition fresh in our minds, let's try to break it down a bit. First of all, when science uses the term Homo sapiens, it's referring to the species of humans that exist today. In other words, you and I are Homo sapiens.

When science uses words like 'less evolved humans,' they're referring to the theory made famous by Charles Darwin, that humans advanced over a vast amount of time, moving along the evolutionary ladder from apes to Homo sapiens.


Building from the theories of Charles Darwin who theorized that humans advanced over a vast amount of time, moving along the evolutionary ladder from apes to Homo sapiens, the Replacement model is also referred to as the Out of Africa model. ... When this occurred, all lesser-evolved humans somehow became extinct.
