The third millennium BCE brought about substantial transformations that are visible in the cultures of Bronze Age Europeans. A new study led by researchers from the Max Planck Institutes for the Science of Human History (Jena) and Evolutionary Anthropology (Leipzig), and the Universitat Autònoma de Barcelona documents the arrival of new genetic ancestry to southern Iberia, concomitant with the rise of the Early Bronze Age El Argar culture around 2,200 BCE.
