2. American origin
3. South Asian origin
4. East Asian origin

Answer 1

Correct Answer - Option 1 : African origin

The correct answer is African origin.

• Human genetics can be traced back to African origin.
• Paleontological and genetic evidence indicates that modern humans originated in Africa within the past 300 thousand years and spread across the globe within the last 100 thousand years.
• Therefore, modern humans have continuously inhabited the African continent longer than any other region.
• Africans have high levels of genetic, cultural, and linguistic diversity as well as extensive population structure.
• More than 2000 ethnolinguistic groups have been identified in Africa, consisting of around one-third of the world’s languages.

• Genetics, the study of heredity in general and of genes in particular.
• Genetics forms one of the central pillars of biology and overlaps with many other areas, such as agriculture, medicine, and biotechnology.
• Since the dawn of civilization, humankind has recognized the influence of heredity and applied its principles to the improvement of cultivated crops and domestic animals.
