According to a new scientific study, conflict between males and females is very frequent among primates, representing over half of all conflicts. The winning gender in confrontations varies considerably from one species to another [1]. Strict dominance (over 90% of confrontations won) for either gender was observed in less than 20% of the populations studied. Conducted by CNRS researchers [2] in collaboration with teams in Germany, these results will be available the week of 7 July in the journal PNAS.
