to deep language ancestry across Eurasia that combines advanced novel statistical modeling techniques and computational methods with paleolinguistic arguments to give theoretical justification to the search for features of language that might be preserved across wide spans of time and geography. Another recent interdisciplinary paper, titled Ancestral Dravidian languages in Indus Civilization: ultraconserved Dravidian tooth-word reveals deep linguistic ancestry and supports genetics, written by Bahata Ansumali Mukhopadhyay, combines archaeological, archaeogenetic, historical and paleolinguistic arguments to establish that a significant population of Indus civilization spoke certain ancestral Dravidian languages. Another important research by Asko Parpola and Christian Carpelan combines archaeological and paleolinguistic evidence and argues that the IndoEuropean and Uralic proto-languages were both spoken in archaeological cultures of eastern Europe, and that even the predecessors and some of the successors of these cultures were in contact with each other.
