Japhetic theory
In linguistics, the Japhetic hypothesis or Japhetic theory (Russian: яфетическая теория, yafeticheskaya teoriya) of Soviet linguist Nikolay Yakovlevich Marr (1864–1934) postulated that the Kartvelian languages of the Caucasus area are related to the Semitic languages of the Middle East. The hypothesis gained favor in the 1930s and '40s among some Soviet linguists for ideological reasons as it was thought to represent "proletarian science" as opposed to "bourgeois science", but also had numerous detractors, most notably Arnold Chikobava.
