Animals fall in love, establish rules for fair play, exchange valued goods and services, hold "funerals" for fallen comrades, deploy sex as a weapon, and communicate with one another using rich vocabularies. Animals also get jealous and violent or greedy and callous and develop irrational phobias, just like us. Monkeys address inequality, wolves miss each other, elephants grieve for their dead, and prairie dogs name the humans they encounter. Human and animal behavior is not as different as once believed. In Not So Different, the biologist Nathan H. Lents argues that the same evolutionary forces of cooperation and competition have shaped both humans and animals. Identical emotional and instinctual drives govern our actions. By acknowledging this shared programming, the human experience no longer seems unique, but in that loss we gain a fuller appreciation of such phenomena as sibling rivalry and the biological basis of grief, helping us lead more grounded, moral lives among animals, our closest kin.Through a mix of colorful reporting and rigorous scientific research, Lents describes the exciting strides scientists have made in decoding animal behavior and bringing the evolutionary paths of humans and animals closer together. He marshals evidence from psychology, evolutionary biology, cognitive science, anthropology, and ethology to further advance this work and to drive home the truth that we are distinguished from animals only in degree, not in kind.

A biology professor''s "funny, fascinating" tour of the physical imperfections—from faulty knees to junk DNA—that make us human (Discover). We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution''s greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there''s been some kind of mistake?As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is indeed nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them. A rollicking, deeply informative tour of humans'' four-billion-year-and-counting evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success."An insightful and entertaining romp through the myriad ways in which the human body falls short of an engineering ideal—and the often-surprising reasons why." —Ian Tattersall, author of The Monkey in the Mirror

We like to think of ourselves as highly evolved. But if we are evolution''s greatest creation, why are we so badly designed? We have retinas that face backward, we must find vitamins and nutrients in our diets that other animals simply make for themselves and millions of us can''t reproduce successfully without help from modern science. And that''s just the beginning of the story. Biologist Nathan H. Lents takes us on an entertaining and illuminating tour of our four-billion-year-long evolutionary saga, and shows us how each of our flaws tells us a story about our species'' history.

'Marvellous fun' THE TIMES'Glorious ' LUCY COOKE'Colourful' GUARDIANWe find ourselves in a time of great social upheaval. People are testing the boundaries of just about everything related to sex and gender. Biological sex, long thought to be a simple binary, is now being understood as a spectrum. Gender is being uncoupled from sex and expanded to an astounding range of diversity. The traditional categories of sexual attraction are being supplanted by more creative labels. Where is this shift coming from? The answer may surprise you. Diverse sexual behaviour is not a new development, or even a human one. It didn't emerge from recent progressive culture, it's the product of billions of years of experimentation throughout the animal kingdom.Evolutionary biologist Nathan H. Lents takes readers on a journey from silent crickets to lesbian albatrosses to bonobos who kiss, revealing what this incredible array of sexual diversity can teach us about our own. Amusing, enlightening and meticulously researched, Lents convincingly shows that diverse genders and sexuality have evolutionary functions far beyond procreation. The Sexual Evolution is a perspective-altering book that advocates understanding and demolishes biases held by even the most open-minded among us.
