|The same linguistic speculation that
led to the Aryan invasion theory has following the same logic required a
"Dravidian invasion." Not only are the Dravidians like the Aryans styled invaders into India, they took
the same route as the Aryans. The city-state of Elam in southwest Iran,
east of Sumeria, which had a high civilization throughout the ancient
period, shows an agglutinative structure like the Dravidian, as does
possibly the Sumerian itself.
This would place Dravidian type languages in Iran as well. Thereby
the Dravidians, just like the Aryans, would have migrated (again the
reason for which is not clear) from Central Asia and into Iran, with one
group moving west to Mesopotamia and the other, apparently larger group, going east into India.
