Kamil V. Zvelebil has suggested that proto-Dravidian was part of a larger Elamo-Dravidian language family. However, George Starostin has disputed the existence of an Elamo-Dravidian language family .

According to a view put forward by geneticist Luigi Luca Cavalli-Sforza in the book "The History and Geography of Human Genes", the Dravidians were preceded in the subcontinent by an Austro-Asiatic people, and followed by Indo-European-speaking migrants sometime later. The original inhabitants may be identified with the speakers of the Munda languages, which are unrelated to either Indo-Aryan or Dravidian languages. However, the Munda languages, as a subgroup of the larger Austro-Asiatic language family, are presumed to have arrived in the Indian subcontinent from the east, possibly from the area that is now southwestern China, so any genetic similarity between the present-day speakers of the Munda languages and the "original inhabitants" of India is likely to be due to assimilation of the natives by Southeast Asian immigrants speaking a proto-Munda language.

Some linguists believe that Dravidian-speaking people were spread throughout the Indian subcontinent before a series of Indo-Aryan migrations. In this view, the early Indus Valley civilization (Harappa and Mohenjo Daro) is often identified as having been Dravidian. Cultural and linguistic similarities have been cited by researchers such as Finnish Indologist Asko Parpola as being strong evidence for a proto-Dravidian origin of the ancient Indus Valley civilization.

Some scholars like J. Bloch and M. Witzel believe that the Dravidians moved into an already Indo-Aryan speaking area after the oldest parts of the Rig Veda were already composed. This theory might be supported if a higher antiquity of the Indo-Aryan languages could be established. However, since this theory is mainly a linguistic hypothesis, the Dravidian influence on Aryan languages need not necessarily be equated to a movement of populations.

The Brahui population of Balochistan has been taken by some as the linguistic equivalent of a relict population, perhaps indicating that Dravidian languages were formerly much more widespread and were supplanted by the incoming Indo-Aryan languages.

Zvelebil remarks that "Several scholars have demonstrated that pre-Indo-Aryan and pre-Dravidian bilingualism in India provided conditions for the far-reaching influence of Dravidian on the Indo-Aryan tongues in the spheres of phonology, syntax and vocabulary".
