Different

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 Frans de Waal explores what we know of biological sex differences and of the role of culture and socialization. From maternal and paternal behaviour to sexual orientation, gender identity, and the limitations of the gender binary, de Waal analyses our shared evolutionary history with the apes, considering what is similar and what sets us apart.
