29 de ago. de 2017 · En la actualidad, los investigadores plantean dos modelos para explicar el origen de Homo sapiens: el primero de ellos se ha llamado modelo “multirregional”; mientras que el segundo es el modelo del “Arca de Noé”, del origen único, o del reemplazamiento (mejor conocido como «fuera de África»).
Según la hipótesis de la evolución multirregional, los primeros humanos que salieron de África hace 1,8 millones de años nunca se dividieron en especies diferentes. En cambio, estas poblaciones siempre intercambiaron genes entre sí a través del flujo genético recurrente.

18 de jul. de 2007 · A new study of thousands of human skulls claims to confirm genetic evidence that our species arose in Africa and then spread over the globe. But some researchers say that an alternative scenario has not been ruled out. Researchers have long debated two opposing hypotheses for modern human origins.
The multiregional hypothesis, multiregional evolution (MRE), or polycentric hypothesis, is a scientific model that provides an alternative explanation to the more widely accepted "Out of Africa" model of monogenesis for the pattern of human evolution.
