Praise for the Work of Frans de Waal Different "Adds an important evolutionary dimension to one of the most complex issues of our time. The beauty of a book by Frans de Waal is that once you read it, you'll never look at your own species the same way again." --Tamra Mendelson, Washington Post "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 Mama's Last Hug A New York Times Bestseller Winner of the PEN / E. O. Wilson Literary Science Writing Award "Game-changing. Puts these most vivid of mental experiences in evolutionary context, revealing how their richness, power, and utility stretch across species and back into deep time." --Sy Montgomery, New York Times Book Review Are We Smart Enough to Know How Smart Animals Are? A New York Times Bestseller "A passionate and convincing case for the sophistication of nonhuman minds.

" --Alison Gopnik, Atlantic "This is a remarkable book by a remarkable scientist. Drawing on a growing body of research including his own, de Waal shows that animals, from elephants and chimpanzees to the lowly invertebrates, are not only smarter than we thought but also engaged in forms of thought we have only begun to understand." --Edward O. Wilson.
