"Renfrew bases his critique of linguistic paleontology particularly on an article by J. Fraser from 1926, but it is also in line with the criticism that Victor Hehn expressed. Several linguists, as well, have remained skeptical about the possibilities and axioms of linguistic paleontology. Most debated is the Russian structuralist Prince Niklaj Trubestkoj (1890-1938), who argues in the famous article "Gedanken uber das Indogermanenproblem" (1936) although it is possible that the similarities between the Indo-European languages are due to a common origin, this hypothesis is not necessary. He found that notion of an original language (the family tree model) more romantic than scientific and imagined that the genetic classification might be replaced with a structuralist one (Arvidsson 2006, p.296)."
