Different: What apes can teach us about gender

How different are the sexes? Is gender uniquely human? Where does gender identity originate?

Drawing on decades of observing our closest living relatives, chimpanzees and bonobos, world-renowned primatologist and New York Times bestselling author Frans de Waal explores what we know of biological sex differences and of the role of culture and socialisation.

From maternal and paternal behaviour to sexual orientation, gender identity, and the limitations of the gender binary, Frans analyses our shared evolutionary history with the apes, considering what is similar and what sets us apart.
