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.
