There are two opposing views about origin of modern man. According to ...
The correct answer is option 'A': Greater variation in Asia than in Africa. This suggests an African origin of modern man based on the study of DNA variation. Let's break down the answer and explain it in detail:
1. Introduction:
- The question is about the opposing views on the origin of modern man.
- One view suggests that Homo erectus in Asia were the ancestors of modern man.
- DNA variation studies, however, suggest an African origin of modern man.
- We need to identify the type of observation on DNA variation that suggests this African origin.
2. Explanation:
- DNA variation refers to the differences or variations in the genetic material (DNA) of individuals within a population.
- In the context of human evolution, studying DNA variation can provide insights into the ancestry and origins of modern humans.
3. African origin hypothesis:
- The African origin hypothesis, also known as the Out of Africa theory or recent African origin theory, proposes that modern humans originated in Africa and then migrated to other parts of the world.
- According to this hypothesis, all modern humans share a common African ancestry.
4. Greater genetic variation in Africa:
- Genetic variation is influenced by factors such as mutation, genetic drift, migration, and natural selection.
- Africa is considered the most genetically diverse continent due to its longer history of human habitation and the presence of diverse ethnic groups.
- The genetic variation in African populations is expected to be higher compared to other regions.
5. DNA variation studies:
- DNA variation studies involve analyzing the genetic markers or sequences in the DNA of individuals from different populations.
- By comparing the genetic variation among populations, researchers can infer patterns of migration, genetic relationships, and origins.
6. Observation of DNA variation:
- If the DNA variation studies show greater genetic variation in Asia compared to Africa, it would suggest that the ancestors of modern humans originated in Africa and then migrated to Asia.
- This observation is consistent with the Out of Africa theory, as it suggests that the genetic diversity in Africa represents a larger ancestral pool from which populations in other regions descended.
7. Conclusion:
- The observation of greater DNA variation in Asia than in Africa would support the hypothesis of an African origin of modern man.
- This suggests that Homo erectus in Asia were not the direct ancestors of modern humans, but rather modern humans originated in Africa and later migrated to different parts of the world.
In summary, the answer 'A' (Greater variation in Asia than in Africa) is the correct option based on the observation of DNA variation. This observation aligns with the African origin hypothesis, indicating that modern humans have their roots in Africa.
