A new study squelches a treasured theory about Indians’ origins

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.
