"New York Times best-selling author and world-renowned primatologist Frans de Waal explores sex and gender in both humans and other animals. Though many scholars now argue that gender differences are purely a product of socialization, primatologist Frans de Waal illustrates in Different the scientific, evolutionary basis for gender differences in humans, drawing on his decades of experience working with our closest ape relatives: chimpanzees and bonobos....

Sir David Attenborough reveals spectacular scenes of courting and companionship. Some species need to overcome the challenges of a vast environment just to find a member of the opposite sex. Others find themselves pitched against their neighbors in mass mating aggregations. Some must impress with complex displays. Others build extraordinary structures just to prove their worth.

Rewriting the science of evolution and sex,...
