Archaeologists challenge theory of violent Steppe invasion in Iberia Peninsula

A study by the Universitat Autònoma de Barcelona (UAB) and the University of Murcia (UM) challenges the theory that warrior groups with a "Steppe" genetic component originating from Eastern Europe violently replaced the male population of the Iberian Peninsula some 4,200 years ago and presents a different scenario, in which groups with Steppe ancestry mixed with other demographically weakened locals.
