Recently, the scientists of the Council of
Scientific and Industrial Research’s
Centre for Cellular and Molecular Biology and Harvard Medical School, USA, have found that India’s caste system is not as old as man himself. It says that various castes were formed when people in the North began intermarrying people from the South about 4200 years ago. While the North Indians were of Central Asian, Middle Eastern, Caucasian and European origin, the South Indians were primarily from the Indian subcontinent. They were genetically different from one another and their intermarriages resulted in new groups of people classified as castes and sub-castes. It happened around the time the Indus Valley Civilization began declining and ended about 2000 years ago.
