Analysis of information sources in references of the Wikipedia article "Dravidian languages" in English language version.
It is generally accepted that Dravidian – with no identifiable cognates among the world's languages – was India's most widely distributed, indigenous language family when Indo-European speakers first intruded from the north-west 3,000 years ago
... together with the evidence of archaeology would seem to suggest that the original Dravidian-speakers entered India from Iran in the fourth millennium BC ...
... The analysis of two Y chromosome variants, Hgr9 and Hgr3 provides interesting data (Quintan-Murci et al., 2001). Microsatellite variation of Hgr9 among Iranians, Pakistanis and Indians indicate an expansion of populations to around 9000 YBP in Iran and then to 6,000 YBP in India. This migration originated in what was historically termed Elam in south-west Iran to the Indus valley, and may have been associated with the spread of Dravidian languages from south-west Iran (Quintan-Murci et al., 2001). ...
... More recently, about 15,000–10,000 years before present (ybp), when agriculture developed in the Fertile Crescent region that extends from Israel through northern Syria to western Iran, there was another eastward wave of human migration (Cavalli-Sforza et al., 1994; Renfrew 1987), a part of which also appears to have entered India. This wave has been postulated to have brought the Dravidian languages into India (Renfrew 1987). Subsequently, the Indo-European (Aryan) language family was introduced into India about 4,000 ybp ...
