According to scientists and historians, the Dravidian people are descendants of Neolithic West Asian farmers from Iran which conquered and largely displaced the outnumbered native hunter gatherers of India.[2] Dravidians are linked to the neolithic Zagros Mountain farmers, and this West Asian population forms the main ancestor of modern South Asians.[3]
A genetic and biogeographical study (Das et al. 2016) concluded that Dravidian peoples belong to the Caucasoid race. According to the study, these proto-Dravidians migrated into India around 8,000 years ago from a region later known as Elam in modern day Iran. The authors suggest that this results support the Elamo-Dravidian hypothesis.[4]
The Indus Valley civilization is suggested to be of Dravidian origin.[5] Genetic tests show that the ancient Indus Valley Civilization was predominantly of neolithic Zagros mountain farmers ancestry (98%) and this ancestry component is linked to early Dravidians.[6]
Kannadigas belong to the south-Dravidian subgroup. Kannadigas are native to Karnataka, parts of northern Kerala,parts of southern Maharashtra, and northwest region of Tamil Nadu, India.
They belong to south-Dravidian linguistic subgroup. Tamils are native to Tamil Nadu, Puducherry, parts of Kerala, southern Andhra Pradesh, southern Karnataka and Sri Lanka.
↑Das R, Upadhyai P. "Tracing the biogeographical origin of South Asian populations using DNA SatNav"(PDF). Our hypothesis is supported by archaeological, linguistic and genetic evidences that suggest that there were two prominent waves of immigrations to India. A majority of the Early Caucasoids were proto-Dravidian language speakers that migrated to India putatively ~ 6000 YBP.
