This event will include a pre-recorded lecture and live Q&A with the author.

In Different, world-renowned primatologist Frans de Waal draws on decades of observation and studies of both human and animal behavior to argue that despite the linkage between gender and biological sex, biology does not automatically support the traditional gender roles in human societies. While humans and other primates do share some behavioral differences, biology offers no justification for existing gender inequalities.

Using chimpanzees and bonobos to illustrate this point—two ape relatives that are genetically equally close to humans—de Waal challenges widely held beliefs about masculinity and femininity, and common assumptions about authority, leadership, cooperation, competition, filial bonds, and sexual behavior. Chimpanzees are male-dominated and violent, while bonobos are female-dominated and peaceful. In both species, political power needs to be distinguished from physical dominance. Power is not limited to the males, and both sexes show true leadership capacities.

With humor, clarity, and compassion, Different seeks to broaden the conversation about human gender dynamics by promoting an inclusive model that embraces differences, rather than negating them.
