Chimpanzee in a field

Territorial boundary patrolling by chimpanzees — where they walk silently in single file, on full alert, and often engage in deadly fights in pursuit of larger territory and more food — is one of the most dramatic forms of collective action in mammals. A new study led by an ASU researcher shows how working together benefits the group, regardless of whether individual chimps patrolled or not.
