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.
