"'In this country, groups which correspond closely to the anthropologists' conception of tribes have lived in long association with communities of an entirely different type. Except in a few areas, it is very difficult to come across communities which retain all their pristine tribal character. In fact, most such tribal groups show in varying degrees elements of continuity with the larger society of India (...) In India hardly any of the tribes exists as a separate society and they have all been absorbed, in varying degrees, into the wider society of India. The on-going process of absorption is not recent but dates back to the most ancient times'. ... 'ethnically speaking, most of the tribes in present-day India share their origins with the neighbouring non-tribal population. India has been a melting-pot of races and ethnic groups, and historians and anthropologists find it difficult to arrange the various distinct cultural, ethnic and linguistic groups in the chronological sequence of their appearance in the sub-continent.'"
