Question

What are the three theories for the emergence of Homo sapiens? Select all that apply. Assimilation model Eurasian model Multiregional Continuity model Transatlantic model Out-of-Africa model

Answer 1

The correct answers are A) Assimilation model. C)Multiregional F) Out-of-Africa model.

The three theories for the emergence of Homo sapiens are the Assimilation model, the Multiregional, the Out-of-Africa model.

The Multiregional model and the Out-of-Africa model are similar in that both accept the idea that Homo Erectus appeared for the first time approximately one million years ago and from there, they move to other parts of Africa and Euro Asia. However, the difference between the two is that the Out-of-Africa model, proposed by Christopher Stringer, states that the Homo Sapiens evolved and emigrated 100, 000 years ago from that region, substituting early humanoid forms. The multiregional model, proposed by Milford Wolpoff, states that multiregional evolution flowed permanently since the times of the Homo Erectus. The Assimilation model was proposed by Erik Trinkaus and Fred Smith, is similar to the Out-of-Africa model, but they considered that the genes changed between Neandertals and modern humans.

Answer 2

The three theories for the emergence of Homo Sapiens are: Assimilation Model, Multiregional Continuity Model and Out-of-Africa Model.

Out-of-Africa model is the model that suggests a single origin of Homo Sapiens, stating that all modern populations descended from those H. Sapiens. This is the dominant model of the geographical origin and migration of H. Sapiens.

Multiregional Continuity Model includes all archaic human forms as a single specie, regardless of its state of evolution. This model also poses that clinal variation (through Centre and Edge) is responsable for the gene flow and selection.

Assimilation Model stands as a middle ground between the other two, affirming that H. Sapiens DID originate in Africa (agreeing with the Out-of-Africa model) but argues that they interbred with other human forms from other continents in order to create the gene flow (like the Multiregional Continuity Model states).
