These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone.What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses.Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.

    Many were fantastic, bizarre creatures that still capture our imagination: the super-predator Tyrannosaurus, the plate-backed Stegosaurus, and the long-necked, long-tailed Diplodocus. Dinosaurs: The Ultimate Guide to How They Lived taps into our enduring interest in dinosaurs, shedding new light on different dinosaur groups. Leading paleontology experts Darren Naish and Paul Barrett trace the evolution, anatomy, biology, ecology, behavior, and lifestyle of a variety of dinosaurs. They also remind us that dinosaurs are far from extinct: they present evidence supporting the evolution of dinosaurs to birds that exist today as approximately ten thousand different species. Throughout their narrative Naish and Barrett reveal state-of-the-art new findings shaping our understanding of dinosaurs. Readers will discover, for example, how the use of CT-scanning enables scientists to look inside dinosaur skulls, thus gaining new insight into their brains and sense organs. Dinosaurs is a must-have for all those wanting to keep up to date about these dynamic, complicated creatures.

    Includes a poster of Theodore Gray's iconic photographic periodic table of the elements! Based on seven years of research and photography by Theodore Gray and Nick Mann, The Elements presents the most complete and visually arresting representation available to the naked eye of every atom in the universe. Organized sequentially by atomic number, every element is represented by a big beautiful photograph that most closely represents it in its purest form. Several additional photographs show each element in slightly altered forms or as used in various practical ways. Also included are fascinating stories of the elements, as well as data on the properties of each, including atomic number, atomic symbol, atomic weight, density, atomic radius, as well as scales for electron filling order, state of matter, and an atomic emission spectrum. This of solid science and stunning artistic photographs is the perfect gift book for every sentient creature in the universe.

    Ernst Stromer led an expedition to Egypt’s Bahariya Oasis in the Sahara and discovered four new species of dinosaurs, including the Tyrannosaurus rex–size predator Spinosaurus. But tragically, all his work was incinerated in 1944 during the Allied bombing of Munich.In 1999, Josh Smith, then a graduate student at the University of Pennsylvania, took his brilliant, precocious team to Egypt under the direction of world-renowned paleontologist Dr. Peter Dodson and blundered onto an archaeological site that yielded awe-inspiring results: all of Dr. Stromer’s early findings, and also an entirely new genus of dinosaur, Paralititan stromeri, one of the largest creatures ever to inhabit the planet.

    Exceptional Coverage. This authoritative volume starts with a clear introduction to the animal world, examining the reasons for the apparently infinite variety of animal forms and major evolutionary developments. Animal anatomy, life cycles and the principles of classification are also explored. This is followed by a superbly illustrated survey of world habitats, showing how they have adapted to each environment, and the threats that face both wildlife and plants today. The main part of the book, an up-to-date and comprehensive animal catalog, looks in detail at each major group and provides fascinating profiles of over 2,000 individual species. Visually Breathtaking. Spectacular photographic portraits bring a vast array of animals vividly to life, with special features on well-known and important animals such as the Galapagos tortoise. Each species profile is supported by maps and symbols showing distribution and habitat, as well as key information on size, population, and conservation status, forming an invaluable reference database. Outstanding Reference. Clear, comprehensive, and thought provoking, the Smithsonian Animal is essential reading for wildlife enthusiasts of all ages and levels of experience.

    A concise atlas of anatomy, it contains more than 200 specially prepared accurate and clear drawings that include material never illustrated before. The text is as informative as the drawings; written at a level appropriate to undergraduate students and to bird lovers in general, it discusses why birds look and act the way they do.Designed to supplement a basic ornithology textbook, the Manual of Ornithology covers systematics and evolution, topography, feathers and flight, the skeleton and musculature, and the digestive, circulatory, respiratory, excretory, reproductive, sensory, and nervous systems of birds, as well as field techniques for watching and studying birds. Each chapter concludes with a list of key references for the topic covered, with a comprehensive bibliography at the end of the volume. The book will be a guide and reference for every level of bird study—a basic tool for investigation for anyone curious about the fascinating world of birds.

    Ranging from the depths of the ocean to the most arid corners of the land, Caspar Henderson captures the beauty and bizzareness of the many living forms we thought we knew and some we could never have contemplated, inviting us to better imagine the precarious world we inhabit.A witty, vivid blend of cutting edge natural history and meditative reflections, The Book of Barely Imagined Beings is infectious and celebratory about the sheer ingenuity and variety of life.

    Bursting with all the suspense and intrigue of a fast paced adventure novel, here is Johanson’s lively account of the extraordinary discovery of “Lucy.” By expounding the controversial change Lucy makes in our view of human origins, Johanson provides a vivid, behind-the-scenes account of the history of pealeoanthropology and the colorful, eccentric characters who were and are a part of it. Never before have the mystery and intricacy of our origins been so clearly and compellingly explained as in this astonighing and dramatic book.

    Moral behavior does not begin and end with religion but is in fact a product of evolution.For many years, de Waal has observed chimpanzees soothe distressed neighbors and bonobos share their food. Now he delivers fascinating fresh evidence for the seeds of ethical behavior in primate societies that further cements the case for the biological origins of human fairness. Interweaving vivid tales from the animal kingdom with thoughtful philosophical analysis, de Waal seeks a bottom-up explanation of morality that emphasizes our connection with animals. In doing so, de Waal explores for the first time the implications of his work for our understanding of modern religion. Whatever the role of religious moral imperatives, he sees it as a “Johnny-come-lately” role that emerged only as an addition to our natural instincts for cooperation and empathy.But unlike the dogmatic neo-atheist of his book’s title, de Waal does not scorn religion per se. Instead, he draws on the long tradition of humanism exemplified by the painter Hieronymus Bosch and asks reflective readers to consider these issues from a positive perspective: What role, if any, does religion play for a well-functioning society today? And where can believers and nonbelievers alike find the inspiration to lead a good life?Rich with cultural references and anecdotes of primate behavior, The Bonobo and the Atheist engagingly builds a unique argument grounded in evolutionary biology and moral philosophy. Ever a pioneering thinker, de Waal delivers a heartening and inclusive new perspective on human nature and our struggle to find purpose in our lives.

    In all the current highly publicized debates about creationism and its descendant "intelligent design," there is an element of the controversy that is rarely mentioned—the "evidence," the empirical truth of evolution by natural selection. Even Richard Dawkins and Stephen Jay Gould, while extolling the beauty of evolution and examining case studies, have not focused on the evidence itself. Yet the proof is vast, varied, and magnificent, drawn from many different fields of science. Scientists are observing species splitting into two and are finding more and more fossils capturing change in the past—dinosaurs that have sprouted feathers, fish that have grown limbs. Why Evolution Is True weaves together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes first proposed by Darwin. In crisp, lucid prose accessible to a wide audience, Why Evolution Is True dispels common misunderstandings and fears about evolution and clearly confirms that this amazing process of change has been firmly established as a scientific truth.

    With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life for the twenty-first century reader.

    Mt. Lockley, who observed rabbits in Wales over a 5 year period, shows that they have a complex community life little understood by the world in general. These vegetarian creatures posses both dignity and 'animality'; psychological factors play as large a part in shaping their lives as they do in ours. One finds, too, that their reputation for promiscuity and wanton reproduction is really undeserved. Lockley built an artificial warren with glass sides and several tracts of natural habitat-an open plain, a woodlot, a lushly vegetated savannah were enclosed and arranged for maximum ease of observation with minimum interference. This controlled rabbit colony was observed every day and night in every season and in all kinds of weather. In Lockley's account, rabbits emerge with characteristics and personalities of their own. The nicknames he gives them (Weary Willie, Timid Timothy, Bold Benjamin, for example) in no way lessen the objective and scientific accuracy of his findings. In fact, this touch of individuality reinforces the observation that rabbits are creatures with interests, wills, and preferences of their own. Female conservatism, scent setting or 'chinning' by dominant males, the ability of the female to absorb her fertilized embryo, the stress of subordinate status...and more, are revealed here.

    Until Mary's incredible discovery, it was widely believed that animals did not become extinct. The child of a poor family, Mary became a fossil hunter, inspiring the tongue-twister, "She Sells Sea Shells by the Seashore." She attracted the attention of fossil collectors and eventually the scientific world. Once news of the fossils reached the halls of academia, it became impossible to ignore the truth. Mary's peculiar finds helped lay the groundwork for Charles Darwin's theory of evolution, laid out in his On the Origin of Species. Darwin drew on Mary's fossilized creatures as irrefutable evidence that life in the past was nothing like life in the present.A story worthy of Dickens, The Fossil Hunter chronicles the life of this young girl, with dirt under her fingernails and not a shilling to buy dinner, who became a world-renowned paleontologist. Dickens himself said of Mary: "The carpenter's daughter has won a name for herself, and deserved to win it."Here at last, Shelley Emling returns Mary Anning, of whom Stephen J. Gould remarked, is "probably the most important unsung (or inadequately sung) collecting force in the history of paleontology," to her deserved place in history.
