Barbary Macaque expert, Dr Bino Majolo, gave an invited talk at the Anthropological Institute and Museum, University of Zurich, on “Between-Group Conflict and Within-Group Affiliation in Primates”. The talk was exploring the possibility that human warfare might be comparable to between-group competition in non-human social animals like Barbary Macaques and, if so, whether between-group competition can elicit within-group cohesion and altruism in non-human primates as observed in humans.
