multi-regional hypothesis

The multi-regional hypothesis is an idea about how modern humans evolved. It suggests that after early humans (like Homo erectus) spread from Africa to different parts of the world, they evolved into modern humans in multiple regions simultaneously, such as Europe, Asia, and Africa. This theory highlights gene flow between populations, meaning that various groups exchanged genetic traits over time. Unlike the "Out of Africa" theory, which proposes that modern humans evolved only in Africa and then migrated, the multi-regional hypothesis emphasizes a more interconnected global development of humans.
