Alarm calling and the initiation of collective responses to danger in humans and chimpanzees

Upon detecting a dangerous element in their environment, humans and other animals typically produced alarm signals, i.e. structures whose function is to warn congeners of the imminence of danger, and prepare a social response. In this talk, I will present studies I have conducted with humans and wild chimpanzees of the Budongo forest (Uganda) to investigate which are the species-typical warning signal and how they help to form collective adaptive reactions to danger.
