I have read a theory about an Elamite-Dravidian family. If farming
started in the Middle East, perhaps Dravidian started in Persia and
spread into India as the language of the first farmers in that
direction, like with Semitoid in Europe. A Dravidian language called
Brahui is still spoken in Baluchistan which is south of Afghanistan.
