A groundbreaking, approachable book on the role of emotions in animal and human societies, from the world-renowned primatologist and author of Are We Smart Enough to Know How Smart Animals Are?

THE NEW YORK TIMES BESTSELLLER In this groundbreaking and entertaining book, primatologist Frans de Waal draws on his renowned studies of the social and emotional lives of chimpanzees, bonobos and other primates, and personal encounters with many other species, to illuminate new ideas and findings about animal emotions. Opening with the moving farewell between Mama, a dying chimpanzee matriarch, and her human friend - the video of which has been watched by millions online - Mama's Last Hug illustrates how profoundly we have underestimated animals' emotional experiences. De Waal's radical proposal is that emotions are like organs: humans haven't a single organ that other animals don't have, and the same can be said of our emotions.

"[De Waal] makes an excellent case for the hypothesis that there is no emotion in our human psyche that we don't see in our closest relatives - and, in fact, in intelligent animals of all kinds, especially mammals and large-brained birds ... A convincing book, and De Waal [is] an excellent observer of primate behaviour [and] immensely knowledgeable... a window into chimps' lives, and a looking glass for our own" - The Times

"Superb... striking... remarkable... illuminating" - New Statesman

"Frans de Waal has spent most of his working life watching chimpanzees, and his findings have changed our understanding of the animal world" - Sunday Times

"After you've read Mama's Last Hug it becomes obvious that animals have emotions. Learn how they resemble us in many ways" - Animals Make Us Human and Animals in Translation

"In Mama's Last Hug, Frans de Waal marshals his wealth of knowledge and experience, toggling expertly between rigorous science and captivating anecdote to explain animal behavior-humans included. While doing so, he rebukes the common conceit that we are necessarily better, or smarter, than our closest relatives'" - What a Fish Knows

"Anyone reading this book will be changed forever. De Waal has spent so many decades watching intently and thinking deeply that he sees a planet that is deeper and more beautiful than almost anyone realizes. In these pages, you can acquire and share his beautiful, shockingly insightful view of life on Earth" - Beyond Words: What Animals Think and Feel

"De Waal is the ultimate zoological magician. His animals hold up mirrors and make you see yourself. Whether you find that terrifying or exhilarating is up to you. He is prescient, unnerving, politically explosive, and always downright entertaining. He can unmake and remake you, and you should let him" - Being a Beast
