Scientist provide evidence that modern-day India is the result of recent population mixture among divergent demographic groups.
The findings describe how India transformed from a country where mixture between different populations was rampant to one where endogamy—that is, marrying within the local community and a key attribute of the caste system—became the norm.
“Only a few thousand years ago, the Indian population structure was vastly different from today,” said co–senior author David Reich, professor of genetics at Harvard Medical School. “The caste system has been around for a long time, but not forever.”
