“Leaf makes a bold, surprising...case that our species has evolved along a fundamentally different path [than primates]. Combining evolutionary biology, anthropology, and psychology, Leaf dismantles the narrative of human development popularized by primatologists...One of the book’s chief strengths is its interdisciplinary scope. Leaf weaves together findings from neuroscience (e.g., FOXP2 gene, Von Economo neurons), evolutionary psychology, and cultural history. He also explores provocative ideas about sexuality, humor, and the role of ‘honest signals’ like blushing and laughter in building trust and social bonds...clear, inviting prose, shrewd arguments and a fresh perspective make it accessible to a wide audience interested in smart reconsiderations of the orthodoxies of human evolution, psychology, and cultural anthropology.”

“The surprise in Jonathan Leaf’s The Primate Myth is that our relationship to the apes may be more distant than we think…. This, Leaf argues, would allow us to develop a species self-image that would be more accurate. It would be good for science, and also good for us.”

– The Washinton Free Beacon

“A remarkable book. Ambitious in scope, highly learned, and engagingly written, Leaf’s work accomplishes two important goals: It gives a real-life and real-time example of how scientific revolutions occur, and it (definitively) changes our understanding of exactly who our closest relatives are and what that relationship tells us about who we are.”

“Illuminating and paradigm changing! Jonathan Leaf overturns decades of assumptions about our human nature and its origin. Realizing that perhaps we have become too complacent in our human story, he poses the empirically driven question, what really has been our path of evolution? Leaf challenges and sheds light on our social, political, and truly life-or-death human decision-making. In a culture of individualism, do we truly realize our capacity for original thought and courage? Leaf is a profound, rare generational thinker. You will rethink our times with a renewed curiosity for human nature and our evolutionary cousins.” 

– Professor Lisa Miller, Department of Psychology, Columbia University and New York Times’ National Bestselling Author of The Awakened Brain

“It’s easy to be cynical about human beings. This book is an antidote. Leaf thinks scientists have made too much of our evolutionary continuity with chimpanzees, which are horrifically violent. In fact, we act more like wolves and dolphins—more altruistic, more prosocial, more creative. Leaf rethinks the famous Milgram electric-shock experiments, the factors leading to suicide, how and why we seek status, and the origins of sexual jealousy. It’s a provocative, wide-ranging book—a must-read for anyone trying to understand human nature.”

“Jonathan Leaf is a brilliant amateur who can illuminate almost anything and who sometimes sees clearly what the experts miss. The experts who have told us that humans are essentially upgraded chimpanzees, he says, have missed a wealth of details that make us more similar to dolphins and whales. We share a remote ancestor with chimps, but once our forebears left the canopy of the tropical forest, we evolved into a large-brained, pair-bonding, cooperative, organizing, and language speaking species. The key is that we became a special kind of herd animal. Leaf fearlessly follows this thread through unexpected territory including why we fight wars; why men are more likely than women to be homosexual; and why humans (but not chimps) commit suicide. The book reflects his deep reading in a dozen disciplines, but Leaf's career as a successful dramatist serves him well. Every page is alive with anecdotes, recollections, and stories of the people who enthroned chimpanzees as our close cousins and thus diverted attention from who we really are.” 

– Peter W. Wood, President, National Association of Scholars and Former Anthropology Professor at Haverford and University of Rochester

“This book shreds conventional wisdom about the origins of human nature. Leaf is a compelling writer and, whichever side of the argument you come down on, you will emerge with a clearer understanding of the challenges facing humanity in an age of ubiquitous information and global aggression.”

– Philip Howard, Author of The Death of Common Sense 

“Jonathan Leaf delves into our brains and our prehistory to discover who we are: animals that hunt, speak, and follow the leader. Moving at ease through a mass of data, The Primate Myth is fascinating, occasionally contentious, and sometimes frightening.”

– Richard Brookhiser, Contributing Editor, National Review

“No one can come away from Jonathan Leaf’s extraordinary survey of the twists and turns of what we know about human nature without recognizing how our understanding of human nature has been abused and distorted for agenda-driven causes. The Primate Myth should be required reading for generalists and specialists alike.”
