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.”
This article details how recent advancements in ancient DNA (aDNA) research are challenging long-held beliefs in archaeology and potentially rehabilitating a previously discredited historical model. For much of the 20th century, archaeological interpretations favored gradual cultural shifts driven by trade and intermingling, downplaying the role of large-scale migrations and distinct ethnic groups. This was partly a reaction against the work of Gustaf Kossinna, a 19th/20th-century archaeologist whose “culture-history” model – linking archaeological cultures directly to specific peoples and their movements – became tainted by association with Nazi ideology.
However, the aDNA revolution, beginning in the late 2000s, has revealed a more dynamic and often disruptive picture of prehistory. Genetic analysis confirms that significant population movements did occur, particularly with the spread of Indo-European languages across Europe and into India. This supports Kossinna’s core idea that cultural changes often accompanied the movement of peoples, though it doesn’t endorse his problematic racial theories.
