v1.c15.172

There is good ground, then, for supposing that, before the coming of the Indo-Āryans, speakers of the Dravidian languages predominated both in Northern and in Southern India; but, as we have seen, older elements are discoverable in the populations of both regions, and therefore the assumption that the Dravidians are aboriginal is no longer tenable. Is there any evidence to show whence they came into India?
