Tamils are not Dravidians.

A new blog in Tamil is started by me exclusively to counter the talks that Tamils were originally Dravidians.

Already a similar thread is going on in this blog in English. There will be additions to it every now and then. But the new blog in Tamil is mainly addressing the Tamils to counter the propaganda that Tamils trace their ancestry to Dravidians who were supposed to have lived in the Indus valley. A multi-pronged analysis is being done to lay bare the fact that Tamils originally belonged to where they are now - in the South of India.
