But our burrowing roots go back to the very beginnings of animal life on earth. Without burrowing, the planet would be very different today. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground.On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows, which altered whole ecosystems. Every day we walk on an earth filled with an under-ground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles.Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters: fires, droughts, storms, meteorites, global warmings—and coolings. In a book filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.

    In the intervening period, many species of early ape and human have lived and died out, leaving behind the fossilized remains that have helped to make the detailed picture of our evolution revealed here.This exciting, up-to-the-minute account is divided into three accessible sections. "In Search of Our Ancestors" examines the contexts in which fossilized remains have been found and the techniques used to study them. "The Fossil Evidence" traces in detail the evolution of apes and humans, from Proconsul to the australopithecines, and Homo erectus to the Neanderthals and Homo sapiens. The latest fossil finds at major new sites such as Dmanisi in Georgia and Gran Dolina in Spain are appraised, and new advances in genetic studies, including the extraction of DNA from extinct human species, are evaluated. "Interpreting the Evidence" reconstructs and explains the evolution of human behavior, describing the development of tool use, the flourishing of the earliest artists, and the spread of modern humans to all corners of the world. The book is superbly illustrated with hundreds of photographs, diagrams, and specially commissioned reconstruction drawings by the artist John Sibbick.

    Your life, your thoughts, your diseases, and your health are all the function of cells.But what do you really know about what goes on inside you?The last time most people thought about cells in any detail was probably in high school or a college general biology class. But the field of cell biology has advanced incredibly rapidly in recent decades, and a great deal of what we may have learned in high school and college is no longer accurate or particularly relevant.The Cell: Inside the Microscopic World that Determines Our Health, Our Consciousness, and Our Future is a fascinating story of the incredible complexity and dynamism inside the cell and of the fantastic advancements in our understanding of this microscopic world.Dr. Joshua Z. Rappoport is at the forefront of this field, and he will take you on a journey to discover:A deeper understanding of how cells work and the basic nature of life on earth.Fascinating histories of some of the key discoveries from the seventeenth century to the last decade and provocative thoughts on the current state of academic research.The knowledge required to better understand the new developments that are announced almost weekly in science and health care, such as cancer, cellular therapies, and the potential promise of stem cells.The ability to make better decisions about health and to debunk the misinformation that comes in daily via media.Using the latest scientific research, The Cell illustrates the diversity of cell biology and what it all means for your everyday life.

    This new edition has been entirely rewritten to take account of the latest work of historians and scientists. The sequence of chapters has been reconstructed in a way that will help students and general readers to understand the key phases in the development of modern evolutionism. The book's substantial bibliography has been updated to serve as a valuable introduction to the immense literature on this topic.

    For each volume, a series editor reads pieces from hundred of periodicals, then selects between fifty and a hundred outstanding works. That selection is pared down to the twenty or so very best pieces by a guest editor who is widely recognized as a leading writer in his or her field. This unique system has helped make the Best American series the most respected -- and most popular -- of its kind. The Best American Science and Nature Writing 2003, edited by Richard Dawkins, is another "eloquent, accessible, and even illuminating" collection (Publishers Weekly). Here are the best and brightest writers on science and nature, writing on such wide-ranging subjects as astronomy's new stars, archaeology, the Bible, "terminal" ice, and memory faults.Natalie Angier Timothy Ferris Ian Frazier Elizabeth F.

    In this selection from The Body, Bill Bryson introduces us to the mysterious, and often devastating, world of disease.

    They made the world theirs long before the rise of dinosaurs. Travelling forward into the Permian and then Triassic periods, we learn how our ancient mammal ancestors evolved from large hairy beasts with accelerating metabolisms to exploit miniaturisation, which was key to unlocking the traits that define mammals as we now know them. Elsa criss-crosses the globe to explore the sites where discoveries are being made and meet the people who make them. In Scotland, she traverses the desert dunes of prehistoric Moray, where quarry workers unearthed the footprints of Permian creatures from before the time of dinosaurs. In South Africa, she introduces us to animals, once called 'mammal-like reptiles', that gave scientists the first hints that our furry kin evolved from a lineage of egg-laying burrowers. In China, new, complete fossilised skeletons reveal mammals that were gliders, shovel-pawed Jurassic moles, and flat-tailed swimmers.This book radically reframes the narrative of our mammalian ancestors and provides a counterpoint to the stereotypes of mighty dinosaur overlords and cowering little mammals. It turns out the earliest mammals weren't just precursors, they were pioneers.

    The pictorial models are useful in understanding relationships. The models also abound in descriptive detail.

    Catch a glimpse of what she saw, touched, smelled, and even tasted during an average workday. Dare to join her as she takes you through a difficult journey of memories, uncovering layers of emotional trauma left behind. Discover the ways she healed from yesterday's pain to live an emotionally balanced life today.

    This hidden army is our immune system, and without it we could not survive the eternal war between us and our microscopic enemies.Immune explores the incredible arsenal that lives within us how it knows what to attack and what to defend, and how it kills everything from the common cold to the plague bacterium. We see what happens when the immune system turns on us, and conversely how impossible life is without its protection. We learn how diseases try to evade the immune system, how they exploit vulnerabilities and even subvert it to their own advantage, and we discover how scientists are designing new drugs to harness the power of the system to advance medicine in the 21st century.Some of the topics explored include why are so many people allergic to cats, but so few to hamsters? Do transplants ever reject their new bodies? What is pus? How does your body develop new weapons for new enemies? Why is cancer so hard for our immune system to fight? How does our immune system remember? Why did the 1918 flu pandemic kill mainly young, healthy people? Why did the 2009 swine flu outbreak lead to a spike in sleep disorders? Can we smell someone else's immune system? And does that help us subconsciously decide who we fall in love with?Immune provides an entertaining, intriguing and accessible account of the body's defenses against disease. Drawing on everything from ancient Egyptian medical texts to cutting-edge medical science, the book takes readers on an adventure packed with weird and wonderful facts about their own defense mechanisms, making this both informative and great fun to read.

    Discusses the evolution of prehistoric ape-like creatures into human beings, theorizing that the key to this transformation was the ability to share & cooperate in a social context.

    Today we can see a recreation of the making of the Laetoli footprints at the American Museum of Natural History, in a stunning diorama which depicts two of our human forebears walking side by side through a snowy landscape of volcanic ash. But how do we know what these three-million-year-old relatives looked like? How have we reconstructed the eons-long journey from our first ancient steps to where we stand today? In short, how do we know what we think we know about human evolution? In The Fossil Trail, Ian Tattersall, the head of the Anthropology Department at the American Museum of Natural History, takes us on a sweeping tour of the study of human evolution, offering a colorful history of fossil discoveries and a revealing insider's look at how these finds have been interpreted--and misinterpreted--through time. All the major figures and discoveries are here. We meet Lamarck and Cuvier and Darwin (we learn that Darwin's theory of evolution, though a bombshell, was very congenial to a Victorian ethos of progress), right up to modern theorists such as Niles Eldredge and Stephen Jay Gould. Tattersall describes Dubois's work in Java, the many discoveries in South Africa by pioneers such as Raymond Dart and Robert Broom, Louis and Mary Leakey's work at Olduvai Gorge, Don Johanson's famous discovery of Lucy (a 3.4 million-year-old female hominid, some 40% complete), and the more recent discovery of the Turkana Boy, even more complete than Lucy, and remarkably similar to modern human skeletons. He discusses the many techniques available to analyze finds, from fluorine analysis (developed in the 1950s, it exposed Piltdown as a hoax) and radiocarbon dating to such modern techniques as electron spin resonance and the analysis of human mitochondrial DNA. He gives us a succinct picture of what we presently think our family tree looks like, with at least three genera and perhaps a dozen species through time (though he warns that this greatly underestimates the actual diversity of hominids over the past two million or so years). And he paints a vivid, insider's portrait of paleoanthropology, the dogged work in the broiling sun, searching for a tooth, or a fractured corner of bone, amid stone litter and shadows, with no guarantee of ever finding anything. And perhaps most important, Tattersall looks at all these great researchers and discoveries within the context of their social and scientific milleu, to reveal the insidious ways that the received wisdom can shape how we interpret fossil findings, that what we expect to find colors our understanding of what we do find. Refreshingly opinionated and vividly narrated, The Fossil Trail is the only book available to general readers that offers a full history of our study of human evolution. A fascinating story with intriguing turns along the way, this well-illustrated volume is essential reading for anyone curious about our human origins.

    Bethell presents a concise yet wide-ranging tour of the flash points of modern evolutionary theory, investigating controversies over common descent, natural selection, the fossil record, biogeography, information theory, evolutionary psychology, artificial intelligence, and the growing intelligent design movement. Bethell's account is enriched by his own personal encounters with of some of our era's leading scientists and thinkers, including Harvard biologists Stephen Jay Gould and Richard Lewontin; British paleontologist Colin Patterson; and renowned philosopher of science Karl Popper.
