Uralic languages hypothesis has, however, been rejected by some specialists in Uralic languages, and has in recent times also been criticised by other Dravidian linguists, such as Bhadriraju Krishnamurti. In her book, "The Uralic language family: facts, myths, and statistics", linguist Angela Marcantonio argues against the existence of the Uralic family, claiming that the languages are no more closely related to each other than they are to various other Eurasian languages. All of these hypotheses are minority views at the present time in Uralic studies. Various unorthodox comparisons have been advanced such as Finno-Basque, Hungarian-Etruscan, and Cal-Ugrian.

Uralic languages resembles Nostratic in including Uralic, Indo-European, and Altaic, but differs from it in excluding the South Caucasian languages, Dravidian, and Afroasiatic and including Chukotko-Kamchatkan, Nivkh, Ainu, and Eskimo–Aleut. It was propounded by Joseph Greenberg in 2000–2002. Similar ideas had earlier been expressed by Heinrich Koppelmann in 1933 and by Björn Collinder in 1965. The hypothesis that the Dravidian languages display similarities with the Uralic language group, suggesting a prolonged period of contact in the past, is popular amongst Dravidian linguists and has been supported by a number of scholars, including Robert Caldwell, Thomas Burrow, Kamil Zvelebil, and Mikhail Andronov.
