Majority of Indians are Descendants of ANI and ASI
In ancient times, people in India believed in intermarriage. But with passage of time, the concept changed and people stopped looking for suitors outside their own groups.
Same concept has been discussed by Shashi Tharoor, a prominent writer. He was of the view that India is one of the countries across the world that has diverse population. India has more than 700 language groups and may be more than the mentioned number.
But now, the condition is quite different. Today, people refrain from mingling with outsiders. A number of studies have been done that reveals that India has witnessed a rich culture of intermarriage. Some of the genetic studies in the recent years have also been able to find the same.
They have carried out genetic studies on modern Indians. A research carried out by a group of researchers from Harvard Medical School in Boston has concluded in their study that two major populations in India were Ancestral North Indians (ANI) and Ancestral South Indians (ASI).
Study's lead researcher David Reich said that majority of the Indians are descendants of above two mentioned population groups.
"There was a major demographic transformation in India from a region where mixture was pervasive to one in which it is very rare because of a shift to endogamy", said study researchers.
