What does the 'multi-regional' hypothesis suggest about human evolution?

• A. Humans evolved exclusively in Africa
• B. Modern humans arose from a single lineage only
• C. Humans evolved simultaneously in different global regions
• D. Human evolution is primarily influenced by climatic changes

Answer: (C)

The 'multi-regional' hypothesis suggests that modern humans evolved simultaneously in different global regions rather than originating from a single location. This idea posits that after the initial migration of Homo erectus out of Africa, the populations in various regions—such as Europe and Asia—interbred and contributed to the development of modern Homo sapiens. This perspective emphasizes the importance of gene flow between regional populations over time, leading to the emergence of anatomically modern humans in various areas of the world. This understanding contrasts with other hypotheses, such as the 'out of Africa' model, which proposes that modern humans arose from a single lineage in Africa and subsequently dispersed globally, replacing other hominin populations without much interbreeding. The multi-regional hypothesis encompasses the view that human traits and characteristics developed in parallel across different regions due to localized evolutionary pressures and environmental adaptations.
