Indo-Aryan migration
An Elamo-Dravidian family connecting Elamite with the Dravidian languages of India was suggested in 1967 by Igor M. Diakonoff and later, in 1974, defended by David McAlpin. In 2012, Southworth proposed that Elamite forms the “Zagrosian family” along with Brahui and, further down the cladogram, the remaining Dravidian languages; this family would have originated in Southwest Asia (southern Iran) and was widely distributed in South Asia and parts of eastern West Asia before the Indo-Aryan migration.
