The Early Upper Palaeolithic (EUP) record in Europe is characterized by major changes in human behavior. Different models explaining these changes have been proposed over the past decades, and the research presented in this volume focuses on answering the question of whether these changes in human behavior are due to local evolution or diffusion processes. Philip Nigst’s work suggests that the development of certain types of technology are not based in independent processes but are actually the result of diffusion at the time of the modern human dispersal into Europe.
