David McAlpin had suggested the date of 3000 BCE and thereabouts for the roots of Dravidian to have arrived in Sind and Gujarat from the Elam-Mesopotamia region, and the same is supported by F C Southworth and others of the Pennsylvania University in their recent paper. The date tallies with our traditional date for the arrival of the Asuras into Divi, and the scaling up of cultural and trade links with West Asia in the Early-Harappan Amri culture.
