A study by the University of Vienna, in collaboration with Harvard University, identifies a newly recognized Caucasus-Lower Volga (CLV) population as a key link in the history of Indo-European languages. This population contributed significantly to the Yamnaya culture and the ancestry of Bronze Age central Anatolians, including Hittite speakers. The findings suggest the CLV group as the source of the proto-Indo-Anatolian language, bridging a historical gap in Indo-European language origins.
