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.
