This volume of essays examines the claim that a linguistic macrofamily can be identified which includes not only the Indo-European and Afroasiatic language families but also the Kartvelian, Uralic, Altaic and Dravidian families. The Nostratic case was put by Aharon Dolgopolsky in his The Nostratic Macrofamily and Linguistic Palaeontology, and it is here evaluated critically by linguists specializing in the language families concerned.
