A pair of landmark studies has identified the originators of the Indo-European family of languages in current-day Russia about 6,500 years ago, the Caucasus Lower Volga people.
>“We can see there was a small group of villages 5,700 to 5,300 years ago with just a couple thousand breeding individuals,” Reich said. “And then there was a demographic explosion, with these people going everywhere.”
A pair of landmark studies published in Nature have identified the origin of the Indo-European family of over 400 languages, spoken by more than 40% of the world's population, to the Caucasus Lower Volga people in present-day Russia around 6,500 years ago.
Harvard researchers traced the origins of the vast Indo-European language family to the Caucasus-Lower Volga region, identifying the ancestral population known as the Yamnaya, who appeared around 3300 BCE and spread from Hungary to western China.
