    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.

    Using video links, IP Factly's Amazing Animal series has been designed to encourage and bolster independent reading. The animals are accompanied by pictures and facts plus video links so children can see the animals and how they behave.

    The animals featured in these pages are either destined for extinction or already extinct in the wild but still alive today, thanks to dedication of a heroic group committed to their continued survival. From the majestic Sumatran rhinoceros to the tiny Salt Creek tiger beetle.Sartore singles out the species most likely to disappear in the next decades, as well as some that have already been lost. Alongside these images are the words of scientists and conservationists who are working to protect and restore populations of endangered species.

    Text and illustrations introduce animals with fur or hair who nurse their young, breathe fresh air, and except for two species give birth to their young alive instead of laying eggs.

    Its unique 'Frontiers' chapters cover materials science, nanotechnology, catalysis, and biological inorganic chemistry, and have been fully updated to reflect advances in these key areas of contemporary research and industrial application.

    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.

    Half of all species could disappear by the end of the century, and scientists now concede that most of America’s endangered animals will survive only if conservationists keep rigging the world around them in their favor. So Mooallem ventures into the field, often taking his daughter with him, to move beyond childlike fascination and make those creatures feel more real. Wild Ones is a tour through our environmental moment and the eccentric cultural history of people and wild animals in America that inflects it—from Thomas Jefferson’s celebrations of early abundance to the turn-of the-last-century origins of the teddy bear to the whale-loving hippies of the 1970s. In America, Wild Ones discovers, wildlife has always inhabited the terrain of our imagination as much as the actual land.The journey is framed by the stories of three modern-day endangered species: the polar bear, victimized by climate change and ogled by tourists outside a remote northern town; the little-known Lange’s metalmark butterfly, foundering on a shred of industrialized land near San Francisco; and the whooping crane as it’s led on a months-long migration by costumed men in ultralight airplanes. The wilderness that Wild Ones navigates is a scrappy, disorderly place where amateur conservationists do grueling, sometimes preposterous-looking work; where a marketer maneuvers to control the polar bear’s image while Martha Stewart turns up to film those beasts for her show on the Hallmark Channel. Our most comforting ideas about nature unravel. In their place, Mooallem forges a new and affirming vision of the human animal and the wild ones as kindred creatures on an imperfect planet.With propulsive curiosity and searing wit, and without the easy moralizing and nature worship of environmental journalism’s older guard, Wild Ones merges reportage, science, and history into a humane and endearing meditation on what it means to live in, and bring a life into, a broken world.

    To reach this unique audience, Whitlock and Schluter motivate learning with interesting biological and medical examples; they emphasize intuitive understanding; and they focus on real data.

It also introduces the principles behind such modern topics as likelihood, linear models, meta-analysis and computer-intensive methods. Instructors and students consistently praise the book's clear and engaging writing, strong visualization techniques, and its variety of fascinating and relevant biological examples.

    In the oceans, though, living space has both vertical and horizontal dimensions: with an average depth of 3800 meters, the oceans offer 99% of the space on Earth where life can develop. And the deep sea, which has been immersed in total darkness since the dawn of time, occupies 85% of ocean space, forming the planet’s largest habitat.  Yet these depths abound with mystery. The deep sea is mostly uncharted—only about 5 percent of the seafloor has been mapped with any reasonable degree of detail—and we know very little about the creatures that call it home. Current estimates about the number of species yet to be found vary between ten and thirty million.  The deep sea no longer has anything to prove; it is without doubt Earth’s largest reservoir of life.Combining the latest scientific discoveries with astonishing color imagery, The Deep takes readers on a voyage into the darkest realms of the ocean. Revealing nature’s oddest and most mesmerizing creatures in crystalline detail, The Deep features more than two hundred color photographs of terrifying sea monsters, living fossils, and ethereal bioluminescent creatures, some photographed here for the very first time. Accompanying these breathtaking photographs are contributions from some of the world’s most respected researchers that examine the biology of deep-sea organisms, the ecology of deep-sea habitats, and the history of deep-sea exploration.An unforgettable visual and scientific tour of the teeming abyss, The Deep celebrates the incredible diversity of life on Earth and will captivate anyone intrigued by the unseen—and unimaginable—creatures of the deep sea.

    Our species emerged out of the depths of time into a world already populated by these great carnivores. Before we mastered iron and later developed firearms, we had few defences against bears--only watchful caution and elaborate ceremonies and sacrifices to ward off fear.Where human populations grow, bears have traditionally dwindled or disappeared. But when we return to the wild, to places where bears still survive, all our primeval fears awaken again. The risk of an automobile accident on the way to bear country far outstrips the risk of a close-range encounter with a bear, but it's the bear that worries us as we hurtle down the pavement at a hundred kilometres an hour.In this timely and sensitive book, Kevin Van Tighem calls on decades of experience, knowledge and understanding in order to enlighten readers about our relationship with and attitude toward bears. Along the way we are confronted with the realities confronting these great animals as a result of our ever-expanding human population and their ever-shrinking natural habitat. Through historical research, field observation, practical advice, personal anecdotes and an array of stunning photos, Van Tighem has written a comprehensive book that is meant to demystify bears in order to promote a deeper understanding of these powerful yet vulnerable creatures.

    This book enables both the casual reader and the seasoned practitioner to understand and implement the anatomical structure and function of the body in yoga. Written with a conversational tone, the book delivers the complex subject of human anatomy in a way that is both provocative and clear. The underlying theme of the book is integration. David Keil outlines how yoga teachers and practitioners can utilize a deeper understanding of their anatomy as they approach the larger scheme of yoga. How do the supposed "parts and pieces" of the body synchronize to support integrated movement? Finally, how do the various yoga postures interrelate from the perspective of functional anatomy? Not only is David Keil an authority on the subject of anatomy, but he also has the wisdom and first-hand experience of a skilled yoga teacher and practitioner. He has been presenting the subject of anatomy in a way that is interesting, meaningful, and applicable to teachers and students alike since 2000. Beautifully illustrated throughout with colour images and photographs to clearly explain the concepts and asanas, Functional Anatomy of Yoga will assist you in reaching new heights in your yoga practice using the "laboratory" of the body and the tools of yoga asana.
