According to Heggarty and Renfrew, Dravidian languages may have spread into the Indian subcontinent with the spread of farming. According to David McAlpin, the Dravidian languages were brought to India by immigration into India from Elam. In earlier publications, Renfrew also stated that proto-Dravidian was brought to India by farmers from the Iranian part of the Fertile Crescent, but more recently Heggarty and Renfrew note that "a great deal remains to be done in elucidating the prehistory of Dravidian." They also note that "McAlpin's analysis of the language data, and thus his claims, remain far from orthodoxy." Heggarty and Renfrew conclude that several scenarios are compatible with the data, and that "the linguistic jury is still very much out." In a 2021 study, Bahata Ansumali Mukhopadhyay presented a linguistic analysis to posit a Proto-Dravidian presence in the ancient Indus area, using Dravidian root words for tooth, toothbrush and elephant in various contemporary ancient civilisations.
