*Evidence substantiating information found in Puranas and Ithihasa, Ramayana and Mahabharata are now being validated by Astronomy, Astroarcheology , Epigraphy, Archeological finds, Tectonic plates movements,C4dating, Infra-red analysis, Stratification studies.
Before going into the Research find,let us look at some seemingly contradictory facts mentioned in the Puranas and Ithihasa.
And cross check them with references in ancient Tamil literature.

This study is based on DNA presence.
It is notable that Rig Vedic Book 7 is ascribed to the sage Vasishta, whose affiliation with the mainly Iranic sun-worshipping Mitra-Varuna tradition is nevertheless codified in the Hindugotra system and became especially popular in the medieval assimilation of sun-worshipping Iranic peoples (Huna, Maitraka, and Gurjar) in Gujarat and the Western states . LPK Brahmins follow the Kaundinya gotra of the Vasishta group. Moreover, Brahmins of the Vasishta gotra occur in significantly higher numbers along the western side of the subcontinent (Supplementary File S42). Taken together, these observations support the possibility of Mitra-Varuna antecedents for LPKSTR LPK families..
