Final answer:
Three hypotheses about the origins of anthropoids include the Out of Africa model, interbreeding with Neanderthals after leaving Africa, and the multiregional evolution model.
Step-by-step explanation:
Three hypotheses about where anthropoids came from include the following:
- Early humans emerged from Africa and then spread out across the globe. This hypothesis is supported by genetic evidence suggesting that the genetic variance in Africa can also be found around the world.
- Early humans interbred with Neanderthals after emerging from Africa, facilitating a genetic exchange that contributed to the diversity seen in modern humans.
- Modern humans evolved in multiple places around the world in a piecemeal fashion, known as the "multiregional evolution model," which posits that Homo sapiens evolved from Homo erectus in several regions simultaneously, accounting for varied human traits globally.
