"A brilliant and fascinating book that brings a scientific, compassionate and balanced approach to some of the hottest controversies about sex and gender." - Yuval Noah Harari, New York Times best-selling author of Sapiens

"This book is superb! Frans de Waal is not only one of the world’s most respected primatologists—he’s also a ballsy feminist who, in these riveting pages, ventures into territory where most writers in academia and letters fear to tread.… These pages are packed with great stories, fascinating data, and thought-provoking ideas. They are sure to spark the important conversations we all—male and female, queer and straight, trans and nonbinary—need to have to create a more just and equitable human society." - Sy Montgomery, author of The Soul of an Octopus

"Moving with fluidity and grace between animal and human models, Frans de Waal demonstrates how many common social prejudices that we deem ‘natural’ are in fact anything but. His crisp writing, his skillful deployment of anecdote, and his deep knowledge of animal science inform this nuanced and profound consideration not only of difference but also of sameness." - Andrew Solomon, author of Far from the Tree and The Noonday Demon

"It is a brave man these days who ventures into the minefield of gender differences. But Frans de Waal relies on a gift for storytelling, a sincere respect for culture, along with intimate knowledge of longtime bonobo and chimpanzee associates to deftly negotiate this treacherous terrain. Wise and humane." - Sarah Blaffer Hrdy, author of The Woman that Never Evolved, Mother Nature, and Mothers and Others
"The current debate on the subject of gender differences is in need of a calm biological assessment which Frans de Waal’s thoughtful book Different gives us." - Desmond Morris, author of The Naked Ape: A Zoologist’s Study of the Human Animal

"Women versus men. Sex versus gender. Biology versus social inculcation. Few domains more effectively tempt fools to rush in than the topic of sex differences. In this case, however, rather than being a fool, Frans de Waal is our wisest primatologist, turning his attention to this irresistible topic. With great clarity, insight, and wit, he examines human sex differences, never once letting us forget that, at the end of the day, we are just another kind of primate. This is a superb, intensely stimulating read." - Robert M. Sapolsky, author of Behave
