<!--QuoteBegin--><div class='quotetop'>QUOTE<!--QuoteEBegin-->To shed light on genetic variability across the Indian subcontinent, the research team analyzed more than 500,000 genetic markers across the genomes of 132 individuals from 25 diverse groups, representing 13 states, all six language families, traditionally "upper" and "lower" castes, and tribal groups.

These genomic analyses revealed two ancestral populations. "<b>Different Indian groups have inherited forty to eighty percent of their ancestry from a population that we call the Ancestral North Indians who are related to western Eurasians, and the rest from the Ancestral South Indians, who are not related to any group outside India,</b>" said co-author David Reich, an associate professor of genetics at Harvard Medical School and an associate member of the Broad Institute of Harvard and MIT. <!--QuoteEnd--><!--QuoteEEnd--><!--QuoteEnd--></div><!--QuoteEEnd-->



What is the time period of these genetic history.
It will never be in the period of 2000BC
