Abstract
Summary of the research findings
Researchers place Caucasus Lower Volga people, speakers of ancestor tongue, in today’s Russia about 6,500 years ago. A pair of landmark studies, published in the journal Nature, identified the originators of the Indo-European family of 400-plus languages, spoken today by more than 40% of the world’s population. DNA evidence places them in current-day Russia during the Eneolithic period about 6,500 years ago. These linguistic pioneers were spread from the steppe grasslands along the lower Volga River to the northern foothills of the Caucasus Mountains, dubbed the Caucasus Lower Volga people; genetic results show they mixed with other groups in the region.
