What does the multiregional hypothesis suggest about modern human evolution?

The multiregional hypothesis posits that modern humans evolved from earlier hominid populations that were distributed across various geographical regions and that this evolution occurred simultaneously in multiple locations. According to this hypothesis, populations in different parts of the world independently evolved into anatomically modern humans while maintaining some level of gene flow between regions. This ongoing evolution indicates that rather than a single origin in Africa, the development of modern humans involved continuous adaptation and change across distinct regional populations. This perspective emphasizes the role of both adaptation to local environments and the influence of interregional interactions in shaping the genetic and phenotypic diversity of humans today.
