A new study led by the University of Cologne involving 25 researchers from across Europe has discovered how climate change more than 12,000 years ago affected prehistoric human populations. The research has uncovered significant changes in population size and density during key periods at the end of the last Ice Age, specifically during the Late Palaeolithic, between 14,000 and 11,600 years ago. The data on the Iberian Peninsula has been summarised by researchers from the University of the Algarve (Portugal) and the University of the Basque Country (UPV/EHU). Alvaro Arrizabalaga of the Consolidated Research Group in Prehistory is in fact the co-author of this study.
