Linguists worldwide mostly reject Nostratic and many other macrofamily hypotheses with the exception of Dené–Yeniseian languages, which has been met with some degree of acceptance.[2] In Russia, it is endorsed by a minority of linguists, such as Vladimir Dybo, but is not a generally accepted hypothesis.[citation needed] Some linguists take an agnostic view.[3][4][5][6] Eurasiatic, a similar grouping, was proposed by Joseph Greenberg (2000) and endorsed by Merritt Ruhlen.
