Answer:
The correct answer is B. The Out-Of-Africa model suggests that Homo sapiens migrated to Europe and Asia replacing populations descended from Neanderthals and older Homo erectus.
Explanation:
The Out-Of-Africa model, also called theory of African emigration, is the theory that maintains that populations of Homo sapiens left Africa and eliminated the existing populations of humans in Asia and Europe.
Studies certify the existence of two expansions, the first approximately 1.9 million years ago and the second approximately 700,000 years ago. Both coincided with periods of very heavy rains in East Africa, turning what is now the Sahara Desert into a savannah. In such a favorable travel environment, movements of large populations throughout the area were remarkably facilitated.
