How do Out of Africa hypothesis and multiregional hypothesis differ?

‘The ‘Out of Africa’ theory believed that humans migrated from Africa to Eurasia replacing all Homo erectus, in contrast to the ‘Multiregional Continuity Theory’ which asserts that the Homo erectus, after leaving Africa were divided into different continents in the world where they slowly evolved…

What is the African multiregional hypothesis?

The Multiregional Hypothesis model of human evolution (abbreviated MRE and known alternatively as Regional Continuity or Polycentric model) argues that our earliest hominid ancestors (specifically Homo erectus) evolved in Africa and then radiated out into the world.

Who proposed the multiregional theory?

Milford H. Wolpoff
Regional Continuity (Wolpoff) The term “multiregional hypothesis” was first coined in the early 1980s by Milford H. Wolpoff and a group of associates as an explanation for the apparent similarities of the remains from the Homo erectus and Homo sapiens inhabiting the same region.

What are the two hypotheses for explaining the emergence of modern humans?

As you can see, figuring out how and when Homo sapiens, the species name for modern humans, came on the world scene is challenging. Let’s explore two hypotheses about human evolution (the multiregional and the African replacement) and then discuss the evidence for each.

What does the multiregional continuity hypothesis suppose?

What does the Multiregional Continuity hypothesis suppose? The transition to modernity took place regionally and without involving replacement.

What is the African replacement model?

The African replacement model is one form of what is referred to in general terms as an out of Africa model. According to the African replacement model, anatomically modern humans arose as a new species (H. sapiens) in Africa between 150 000 and 200 000 years ago.

What is the Monogenesis hypothesis of human evolution?

Monogenism or sometimes monogenesis is the theory of human origins which posits a common descent for all human races.

What does multiregional continuity hypothesis?

What does the out of Africa theory say about the origins of modern humans?

The ‘out of Africa’ model is currently the most widely accepted model. It proposes that Homo sapiens evolved in Africa before migrating across the world. On the other hand, the ‘multi-regional’ model proposes that the evolution of Homo sapiens took place in a number of places over a long period of time.

What is the candelabra theory?

The so-called “Candelabra Theory” of regional continuity (left) suggests that diversity among extant human populations arose originally from within Homo erectus and has continued over several million years, with some exchange of genes (arrows).
