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. These are considered at best
Uralic languages three families where gradation "is" found) is noted by Helimski (1995): an original allophonic gradation system between voiceless and voiced stops would have been easily disrupted by a spreading of voicing to previously unvoiced stops as well. A computational phylogenetic study by Honkola, et al. (2013) classifies the Uralic languages as follows. Estimated divergence dates from Honkola, et al. (2013) are also given. Structural characteristics generally said to be typical of Uralic languages include: Basic vocabulary of about 200 words, including body parts (e.g. eye, heart, head, foot, mouth), family members (e.g. father, mother-in-law), animals (e.g. viper, partridge, fish), nature
