Question

Single origin of Homo sapiens in Africa and replacement of Homo erectus in Europe, Africa and Asia is explained in the model for the origin of modern man:

• A. Out of Africa model
• B. Candelabra model
• C. Tamura model
• D. Stone King model

Answer 1

Answer:

A. Out of Africa model

The Out-of-Africa model is a hypothesis that explains the origin and spread of modern humans: Origin: Modern humans, or Homo sapiens sapiens, evolved in East Africa. Migration: Around 70,000–100,000 years ago, modern humans migrated out of Africa and replaced archaic human populations around the world. Genetic variation: Most genetic variation in humans is found in Africa, suggesting that humans evolved there for the longest time.
