Scholars successfully apply linguistic paleontology and comparative methods to reconstruct the historic culture, agriculture, and social organization of language families other than Proto-Indo-European, such as Transeurasian, Austronesian, and Tibeto-Burman.
The claim states that reconstructive efforts of proto-languages have inferred historic culture for language families other than PIE. Several provided papers demonstrate the use of linguistic paleontology and phylogenetic comparative methods on non-PIE families, including Transeurasian (Paper 6), Austronesian (Paper 9), and Tibeto-Burman (Paper 10). Thus, the claim is well-supported by the literature.
