Key Concepts

Multiregional Evolution Model

The multiregional evolution model is a theory of human evolution proposing that modern humans evolved from earlier hominin populations across several geographic regions simultaneously, with continuous gene flow between these populations that preserved overall shared characteristics in modern humans.

Gene Flow

Gene flow is the transfer of genetic material between populations. In the context of multiregional evolution, it is crucial because ongoing interbreeding among geographically separated populations helped maintain genetic similarities, ensuring that regional differences did not lead to completely isolated evolutionary paths.

Regional Continuity

Regional continuity refers to the idea that local populations of early humans evolved into modern human groups in their respective regions. This concept underpins the multiregional evolution model by arguing that, despite regional adaptations, there was an ongoing genetic exchange that resulted in a continuous evolutionary progression towards modern humans.

Human Evolution

Human evolution encompasses the study of the biological and cultural development of Homo sapiens from their ancestral hominin species. It includes various models, such as the multiregional and out-of-Africa hypotheses, which seek to explain the origin, dispersion, and development of modern human populations.
