The Multiregional hypothesis

The Multiregional hypothesis suggests that modern humans evolved simultaneously in different regions of the world from local populations of earlier humans, like Homo erectus. Instead of all humans evolving in Africa and then spreading out, this theory proposes that gene flow occurred between populations across Africa, Asia, and Europe. This ongoing exchange allowed these groups to develop into a single, interconnected species—Homo sapiens—over time. It emphasizes continuous regional evolution and interbreeding, resulting in the diverse but connected human populations we see today.
