Final answer:
The multiregional hypothesis of Neanderthals suggests that early humans emerged from Africa, interbred with Neanderthals, and then spread out to populate different parts of the globe.
Step-by-step explanation:
The multiregional hypothesis of Neanderthals suggests that early humans emerged from Africa, interbred with Neanderthals, and then spread out to populate different parts of the globe.
This hypothesis proposes that multiple populations of early humans existed simultaneously and interbred with Neanderthals, leading to the development of different regional variants of humans.
However, it's important to note that the multiregional hypothesis is not universally accepted, and alternative theories such as the Out of Africa hypothesis also exist.
