In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    It produced a cloud of roiling debris that blackened the sky for months as well as other geologic disasters--and triggered the demise of Tyrannosaurus rex. We know what happened largely because Walter Alvarez--synthesizing the findings of experts from a variety of scientific fields--has written a gripping story of the decades-long search for the cause of the dinosaurs' extinction. Painstakingly assembling clues from the Italian Apennines and the depths of the Pacific and presenting them with the excitement of a great novel, T. rex and the Crater of Doom is a book of undeniable importance and irresistible appeal by a major figure in contemporary science. " Engaging and witty. Read Alvarez for and excellent account of how scientists pose questions and seek to solve them." --Scientific American " First-rate...Alvarez provides the up-close tale of the comet or asteroid that wiped out the dinosaurs." --San Francisco Chronicle

    In this book the Dutchers reflect on the virtues they observed in wolf society and behavior. Each chapter exemplifies a principle, such as kindness, teamwork, playfulness, respect, curiosity, and compassion. Their heartfelt stories combine into a thought-provoking meditation on the values shared between the human and the animal world. Occasional photographs bring the wolves and their behaviors into absorbing focus.

    Fully grown they can measure 10 feet and weigh close to 2,000 pounds, but at birth they are just 20 ounces. Creatures that may wander thousands of miles over the course of a year, they begin life in a snowdrift.Human encounters with these legendary beasts are cause for both excitement and apprehension. Tales throughout history describe the ferocity of polar bear attacks on humans; but human hunting of polar bears has exacted a far larger toll, obliging Arctic nations to try to protect their region’s iconic species before it’s too late.Now, however, another threat to the polar bears’ survival has emerged, one that is steadily removing sea ice and the life it supports. Without this habitat, polar bears cannot exist. The Great White Bear celebrates the story of this unique species. Through a blend of history, both natural and human, through myth and reality and observations both personal and scientific, Kieran Mulvaney masterfully provides a context for readers to consider the polar bear, its history, its life, and its uncertain fate.

    What is going on inside the head of a nightingale as it sings, and how does its brain improvise? How do desert birds detect rain hundreds of kilometers away? How do birds navigate by using an innate magnetic compass?Tracing the history of how our knowledge about birds has grown, particularly through advances in technology over the past fifty years, Bird Sense tells captivating stories about how birds interact with one another and their environment. More advanced testing methods have debunked previously held beliefs, such as female starlings selecting mates based on how symmetrical the male's plumage markings are. (Whereas females can discern the difference between symmetrical and asymmetrical markings, they are not very good at detecting small differences among symmetrically marked males!)Never before has there been a popular book about how intricately bird behavior is shaped by birds' senses. A lifetime spent studying birds has provided Tim Birkhead with a wealth of fieldwork experiences, insights, and a unique understanding of birds, all firmly grounded in science. No one who reads Bird Sense can fail to be dazzled by it.

    Peter Allison gives us the guide’s-eye view of living in the bush, confronting the world’s fiercest terrain of wild animals and, most challenging of all, managing herds of gaping tourists. Passionate for the animals of the Kalahari, Allison works as a top safari guide in the wildlife-rich Okavango Delta. As he serves the whims of his wealthy clients, he often has to stop the impulse to run as far away from them as he can, as these tourists are sometimes more dangerous than a pride of lions. No one could make up these outrageous-but-true tales: the young woman who rejected the recommended safari-friendly khaki to wear a more “fashionable” hot pink ensemble; the lost tourist who happened to be drunk, half-naked, and a member of the British royal family; establishing a real friendship with the continent’s most vicious animal; the Japanese tourist who requested a repeat performance of Allison’s being charged by a lion so he could videotape it; and spending a crazy night in the wild after blowing a tire on a tour bus, revealing that Allison has as much good-natured scorn for himself. The author’s humor is exceeded only by his love and respect for the animals, and his goal is to limit any negative exposure to humans by planning trips that are minimally invasive—unfortunately it doesn’t always work out that way! Peter Allison is originally from Sydney, Australia. His safaris have been featured in National Geographic, Conde Nast Traveler, and on television programs such as Jack Hanna's Animal Adventures. He travels frequently to speaking appearances, and splits most of his time between Botswana, Sydney, and San Francisco.

    Current estimates suggest that the rate of extinction is now thousands of times that counted in the fossil record before the emergence of modern man. At the same time, human societies themselves are in a cultural extinction crisis, with experts anticipating that of the world's nearly seven thousand languages as few as ten percent may survive into the next century. Melanie Challenger's extraordinary book is an exploration of how we might live to resist these extinctions and why such disappearances must be of concern to us. Adventurous, curious and passionate about her subject, Challenger takes us on a very personal journey as she tries to restore her own relationship with nature. The narrative unfolds through a series of landscapes haunted by extinction. From the ruined tin mines of Cornwall and the abandoned whaling stations of South Georgia to the Inuit camps of the Arctic and the white heart of Antarctica, she probes the critical relationship between human activities and environmental collapse. This is the first book to weave together the strands of cultural, biological and industrial extinctions into a meditation on the way we live beside nature in the modern world.

    A historical and cultural exploration of the hedgehog, this is an engaging, informative, and charming look at the fascinating world of hedgehogs.For more than twenty years, Hugh Warwick has tracked hedgehogs across the globe in the slim hopes of coming across the hedgehog's tiny, but unmistakable, pawprints. Warwick isn't alone in his endeavors. In England and Wales, the Environment Agency, Great Britain's leading environmental group, recently selected the hedgehog as its new mascot; while in America, which lacks a native hedgehog species, fanciers flock to the biannual Mile High Hedgehog Show to celebrate en masse the little spiny urchin. But why does the hedgehog seem to have such universal appeal?

    In their place evolved an enormous variety of land creatures, especially the mammals, which in their way were every bit as remarkable as their Mesozoic cousins.The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth gigantic hornless rhinos, sabertooth cats, mastodonts and mammoths, and many other creatures--including our own ancestors.Their story is part of a larger story of a world emerging from the greenhouse conditions of the Mesozoic, warming up dramatically about 55 million years ago, and then cooling rapidly so that 33 million years ago the glacial ice returned. The earth's vegetation went through equally dramatic changes, from tropical jungles in Montana and forests at the poles, to grasslands and savannas across the entire world. Life in the sea also underwent striking evolution reflecting global climate change, including the emergence of such creatures as giant sharks, seals, sea lions, dolphins, and whales.After the Dinosaurs is a book for everyone who has an abiding fascination with the remarkable life of the past.

    In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.

    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.

    Pepperberg and Alex, an African Grey parrot who proved scientists and accepted wisdom wrong by demonstrating an astonishing ability to communicate and understand complex ideas. The story is much more than of an incredible scientific breakthrough. It s a poignant love story and an affectionate remembrance of Pepperberg s irascible, unforgettable, and always surprising best friend.

    With a text suitable for both a lay and a scientific audience, the book provides an unforgettable tour of Earth's most evolved animal societies. Each colony of leafcutters contains as many as five million workers, all the daughters of a single queen that can live over a decade. A gigantic nest can stretch thirty feet across, rise five feet or more above the ground, and consist of hundreds of chambers that reach twenty-five feet below the ground surface. Indeed, the leafcutters have parlayed their instinctive civilization into a virtual domination of forest, grassland, and cropland—from Louisiana to Patagonia. Inspired by a section of the authors' acclaimed The Superorganism, this brilliantly illustrated work provides the ultimate explanation of what a social order with a half-billion years of animal evolution has achieved.
