Female bonobos form groups to outmaneuver male aggression and gain resources, study finds.

Female bonobos in Congo form "girl groups" to fend off male aggression and secure resources, according to a study. Despite males being physically stronger, these female-dominated societies use cooperation to maintain social order and improve their standing. Observations over three decades show that female bonobos who group together rank higher and successfully deter male aggression, highlighting a unique social strategy among primates.
