Question: What two lines of evidence provide strong support the Out of Africa hypothesis?

What is the hypothesis known as the Out of Africa model?

The first theory, known as the ‘Out of Africa’ model, is that Homo sapiens developed first in Africa and then spread around the world between 100 and 200,000 years ago, superseding all other hominid species. The implication of this argument is that all modern people are ultimately of African descent.

Can man said to evolved from Africa?

KEY FACTModern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus. Modern humans (Homo sapiens), the species? that we are, means ‘wise man’ in Latin.

What is the African Multiregionalism hypothesis?

The first, or the multiregional hypothesis, states that Homo sapiens evolved from Homo erectus outside of Africa. This hypothesis suggests that Homo erectus slowly wandered out of Africa and inhabited other regions.

Who proposed multiregional hypothesis?

In the 1970s, paleontologist W.W. Howells proposed an alternate theory: the first Recent African Origin model (RAO), called the “Noah’s Ark” hypothesis. Howells argued that H. sapiens evolved solely in Africa.

What color was the first human?

The results of Cheddar Man’s genome analysis align with recent research that has uncovered the convoluted nature of the evolution of human skin tone. The first humans to leave Africa 40,000 years ago are believed to have had dark skin, which would have been advantageous in sunny climates.

What animal did humans evolve from?
