Linguists or Nationalists: Who was Right About the Origin of Indian Civilization?

A CENTURY and a half ago linguists invented a new map of the world. Their research showed that a single family tree stretches its branches almost unbroken across most of Eurasia: from Iceland to Bangladesh, most people speak languages descended from “Proto-Indo-European”. The philologists had a theory to explain why Sanskrit, the ancient forebear of Hindi, has closer cousins in Europe than in south India. They speculated that at some point before the composition of the Vedas, the oldest texts of Hinduism, an Aryan people had migrated into India from the north-west, while their kin pushed westward into Europe.

Long before the Nazis dreamed of an exalted master race, imperialists seized on what some dubbed the “Aryan invasion” theory to paint Britain’s rule of India as the extension of a “natural” order. Indians, too, found a use for it. Caste-bound Hindu conservatives declared that the paler-skinned intruders must be ancestors of higher-caste Brahmins and Kshatriyas. Such talk stirred a backlash in southern India, where generally darker-skinned speakers of Dravidian languages were urged to see themselves as a separate nation.

Hindu nationalists took a different tack. The West, some said, had made up the theory to set Hindus against each other. Christian missionaries and communists were using it to stoke caste hatred and so to recruit followers, they claimed. Worse, the theory challenged an emerging vision of Mother India as a sacred Hindu homeland. If the first speakers of Sanskrit and the creators of the Vedas had themselves been intruders, it was harder to portray later Muslim and Christian invaders as violators of a purity that good Hindus should seek to restore. So it was that some proposed an alternative “Out of India” theory. This held that the original Aryans were in fact Indians, who carried their Indo-European language and superior civilisation to the West.


An accumulating pile of research using DNA from both ancient human remains and modern people indicates strongly that, beginning around 2000BC, north-west India was indeed infused with new blood. The newcomers appear to have shared the same roots in what is now southern Russia as did the invaders of a similar-sized peninsula to the west called Europe. Strikingly, too, the genetic markers identifying this group seem to be far more prevalent among modern north Indian Brahmins than among other Indians.

Because of the difficulty in collecting ancient DNA, such research has until recently relied on relatively few samples. But an international team of 92 scholars, including David Reich, a geneticist at Harvard University who has pioneered techniques to analyse DNA more quickly and precisely, is set to publish data recovered from 362 “ancient individuals” from across South and Central Asia. Among their conclusions: there was probably an early migration of agriculturalists into India from what is now Iran, around 4000BC, and this was followed two millennia later—just before the Vedic Age—by a large influx from what is now southern Russia.
