We’ll look at what identical twins can teach us about the epigenetic effects of our environment and experiences, why certain genes are 'switched on' or off at various stages of embryonic development, and how scientists have reversed the specialization of cells to clone frogs from a single gut cell. In Introducing Epigenetics, Cath Ennis and Oliver Pugh pull apart the double helix, examining how the epigenetic building blocks and messengers that interpret and edit our genes help to make us, well, us.

    Unlikely Friendships tells one story after another of animals who, with nothing else in common, bond in the most unexpected ways and thrive on the warmth, closeness, and trust that come with being true friends.Imagine a predator cuddling its prey. Or a bird befriending a mammal. Or a fish poking its nose out of the water to nuzzle a dog. Or a massive gorilla - the one named Koko, famous for her ability to communicate in sign language - embracing a tiny kitten.Science writer Jennifer S. Holland narrates each story, and also offers insights into these relationships. Sometimes there are plausible scientific explanations: an orphan seeking comfort from an older animal; an adult yearning for a younger creature to nurture. Consider the lioness who befriended and protected a baby oryx - unexpected, but not inexplicable. Sometimes a friendship is about need, as in the case of the blind Lab and her "seeing-eye" cat. B ut sometimes it's just a lovely mystery. How else can one explain the story of Owen the hippo and Mzee the tortoise, two notoriously surly creatures who became bosom buddies?Each story reveals the true power of friendship and, to some degree, the many forms of "love" that seem to exist in the animal kingdom. Yes, scientists might scoff at that notion, but readers may feel a little differently about the world after they finish this book.

    In this much-anticipated book, Michael Tomasello weaves his twenty years of comparative studies of humans and great apes into a compelling argument that cooperative social interaction is the key to our cognitive uniqueness. Once our ancestors learned to put their heads together with others to pursue shared goals, humankind was on an evolutionary path all its own.Tomasello argues that our prehuman ancestors, like today's great apes, were social beings who could solve problems by thinking. But they were almost entirely competitive, aiming only at their individual goals. As ecological changes forced them into more cooperative living arrangements, early humans had to coordinate their actions and communicate their thoughts with collaborative partners. Tomasello's "shared intentionality hypothesis" captures how these more socially complex forms of life led to more conceptually complex forms of thinking. In order to survive, humans had to learn to see the world from multiple social perspectives, to draw socially recursive inferences, and to monitor their own thinking via the normative standards of the group. Even language and culture arose from the preexisting need to work together. What differentiates us most from other great apes, Tomasello proposes, are the new forms of thinking engendered by our new forms of collaborative and communicative interaction.A Natural History of Human Thinking is the most detailed scientific analysis to date of the connection between human sociality and cognition.

    That word is formication, and the implied sense of horror and fascination, contends Richard Conniff, is something many of us actually crave. His Spineless Wonders presents an unabashed wallow in the joy of formication. Spineless Wonders is an engaging, sophisticated, and humorous mix of natural history and human lore. Through his journalistic assignments, Richard Conniff has been in contact with invertebrates for more than twenty years - tarantulas in the upper Amazon region, dragonflies in Arizona, squid in Florida, and flies on the rim of his beer glass. Discoveries about the extraordinary habits and idiosyncrasies of the moth, the leech, the ant, and the slime eel are opening new frontiers in the exploration of our natural universe. Spineless Wonders takes us directly to these wild and wonderful outposts to observe the hazards of being around invertebrates, the bizarre adaptions that enable them to survive in the world, and also the astonishing work they do - work that enables us to survive.

    Our instincts—for food, sex, or territorial protection— evolved for life on the savannahs 10,000 years ago, not in today’s world of densely populated cities, technological innovations, and pollution. We now have access to a glut of larger-than-life objects, from candy to pornography to atomic weapons—that gratify these gut instincts with often-dangerous results. Animal biologists coined the term “supernormal stimuli” to describe imitations that appeal to primitive instincts and exert a stronger pull than real things, such as soccer balls that geese prefer over eggs. Evolutionary psychologist Deirdre Barrett applies this concept to the alarming disconnect between human instinct and our created environment, demonstrating how supernormal stimuli are a major cause of today’s most pressing problems, including obesity and war. However, Barrett does more than show how unfettered instincts fuel dangerous excesses. She also reminds us that by exercising self-control we can rein them in, potentially saving ourselves and civilization. 55 illustrations.

    But when one evening at twilight a lone black wolf ambled into view not far from his doorstep, Nick would finally come to know this mystical species—up close as never before.A Wolf Called Romeo is the remarkable story of a wolf who returned again and again to interact with the people and dogs of Juneau, living on the edges of their community, engaging in an improbable, awe-inspiring interspecies dance and bringing the wild into sharp focus. At first the people of Juneau were guarded, torn between shoot first, ask questions later instincts and curiosity. But as Romeo began to tag along with cross-country skiers on their daily jaunts, play fetch with local dogs, or simply lie near Nick and nap under the sun, they came to accept Romeo, and he them. For Nick it was about trying to understand Romeo, then it was about winning his trust, and ultimately it was about watching over him, for as long as he or anyone could.Written with a deft hand and a searching heart, A Wolf Called Romeo is an unforgettable tale of a creature who defied nature and thus gave humans a chance to understand it a little more.

    Illustrated throughout, this handbook of birds covers the most common British and European birds in detail.

    In studying the natural and human forces that shape the rivers and mountains of that region, geologist David Montgomery has learned to see the evolution and near-extinction of the salmon as a story of changing landscapes. Montgomery shows how a succession of historical experiences -first in the United Kingdom, then in New England, and now in the Pacific Northwest -repeat a disheartening story in which overfishing and sweeping changes to rivers and seas render the world inhospitable to salmon. In King of Fish , Montgomery traces the human impacts on salmon over the last thousand years and examines the implications both for salmon recovery efforts and for the more general problem of human impacts on the natural world. What does it say for the long-term prospects of the world's many endangered species if one of the most prosperous regions of the richest country on earth cannot accommodate its icon species? All too aware of the possible bleak outcome for the salmon, King of Fish concludes with provocative recommendations for reinventing the ways in which we make environmental decisions about land, water, and fish.

    This is the funny, poignant story of their two decades together.On Valentine's Day 1985, biologist Stacey O'Brien first met a four-day-old baby barn owl -- a fateful encounter that would turn into an astonishing 19-year saga. With nerve damage in one wing, the owlet's ability to fly was forever compromised, and he had no hope of surviving on his own in the wild. O'Brien, a young assistant in the owl laboratory at Caltech, was immediately smitten, promising to care for the helpless owlet and give him a permanent home. Wesley the Owl is the funny, poignant story of their dramatic two decades together. With both a tender heart and a scientist's eye, O'Brien studied Wesley's strange habits intensively and first-hand -- and provided a mice-only diet that required her to buy the rodents in bulk (28,000 over the owl's lifetime). As Wesley grew, she snapped photos of him at every stage like any proud parent, recording his life from a helpless ball of fuzz to a playful, clumsy adolescent to a gorgeous, gold-and-white, macho adult owl with a heart-shaped face and an outsize personality that belied his 18-inch stature. Stacey and Wesley's bond deepened as she discovered Wesley's individual personality, subtle emotions, and playful nature that could also turn fiercely loyal and protective -- though she could have done without Wesley's driving away her would-be human suitors! O'Brien also brings us inside the prestigious research community, a kind of scientific Hogwarts where resident owls sometimes flew freely from office to office and eccentric, brilliant scientists were extraordinarily committed to studying and helping animals; all of them were changed by the animal they loved. As O'Brien gets close to Wesley, she makes important discoveries about owl behavior, intelligence, and communication, coining the term "The Way of the Owl" to describe his inclinations: he did not tolerate lies, held her to her promises, and provided unconditional love, though he was not beyond an occasional sulk. When O'Brien develops her own life-threatening illness, the biologist who saved the life of a helpless baby bird is herself rescued from death by the insistent love and courage of this wild animal. Enhanced by wonderful photos, Wesley the Owl is a thoroughly engaging, heartwarming, often funny story of a complex, emotional, non-human being capable of reason, play, and, most important, love and loyalty. It is sure to be cherished by animal lovers everywhere.
