Here are the tentative conclusions drawn from the latest human genetics findings. They are taken mostly from the following three papers:
1) Basu et al. (2003) Ethnic India: A genomic view, with special reference to peopling and structure, Genome Research, 13, 2277-2290.
2) Bamshad et al. (2001) Genetic evidence on the origins of the Indian caste populations, Genome Research, 11, 994-1004.
3)Cann, R. (2001) Genetic clues to dispersal in human populations: Retracing the past from the present, Science, 291, 1742-1748.
When exactly the Indian subcontinent was first populated by modern humans is not known with any degree of certainty. However, genomic studies indicate that India was settled very soon after humans emerged out of Africa. These studies provide the mean upper and lower limits for this event - 63,000 years and 32,000 years before the present (B.P.), respectively.
