Multiregional Paleoanthropologists have been searching for decades, looking for signs of early human life throughout Africa Asia and Europe, trying to find clues that tell them where the human race originated.
Inour earliest ancestor Lucy, a woman of the Australopithecus family, was found in Ethiopia. However, despite her major contribution to science, Lucy was not the only human-like species to be found in Africa.
Inthe two million year old remains of the Australopithecus sediba were discovered in Johannesburg, South Africa. Paleontologists determined that its human-like features in South Africa developed just as the afarensis developed in the East.
The evolution of the two genuses into the eventual modern day humans shows that several different species of humans existed in Africa two million years ago. Our species, the modern day humans- Homo sapiens, are of the genus Homo.
Homo sapiens evolved from primates such as monkeys, orangutans, and chimpanzees on the basis that they could walk upright, making them become classified under the family Hominidae.
The Homo erectus, our direct ancestor, shows several key physiological differences from its predecessor, the Australopithecus including a smaller mouth size, an increase in brain size as well as an increase cranial capacity. With the general consensus that humans have ties in Africa, two hypotheses have attempted to explain the origin of modern humans in a different light.
The Out-of-Africa hypothesis proposes that a migration out of Africa happened aboutyears ago, in which modern humans of African origin conquered the world and completely replaced the Homo erectus, which had already established itself in regions such as Eurasia.
The multiregional hypothesis states that Homo sapiens evolved from several, different human populations in different areas of the world during the million years since Homo erectus migrated out of Africa.
Despite both hypotheses having their own rebuttals, the former is more widely accepted, demonstrating that a larger part of the population seems to feel that modern-day humans evolved out of Africa only recently, making their ties to the continent stronger.
Modern-day Africa currently houses over 1.

As a future neuroscience-major at Pomona College, she enjoys writing articles on topics that will pique the interest of her audience. She hopes to influence her readers into changing their opinion on topics personal to them, or their lifestyle.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.
