To me, the perhaps the most interesting thing is the article is the late Neolithic immigration from the Zagros - it'd fit well with the Elamo-Dravidian idea, i.e., the idea, suggested on linguistic grounds, that the Elamite language was a distant relative of the Dravidian languages of (mostly) southern India.
