But countless questions remain about our great journey from the birthplace of Homo sapiens to the ends of the Earth. How did we end up where we are? When did we get there? Why do we display such a wide range of colors and features? The fossil record offers some answers, but exciting new genetic research reveals many more, since our DNA carries a complete chronicle of our species and its migrations. In Deep Ancestry, scientist and explorer Spencer Wells shows how tiny genetic changes add up over time into a fascinating story. Using scores of real-life examples, helpful analogies, and detailed diagrams and illustrations, he translates complicated concepts into accessible language and explains exactly how each and every individual's DNA contributes another piece to the jigsaw puzzle of human history. The book takes readers inside the Genographic Project, the landmark study now assembling the world's largest collection of population genetic DNA samples and employing the latest in testing technology and computer analysis to examine hundreds of thousands of genetic profiles from all over the globe. Traveling backward through time from today's scattered billions to the handful of early humans who are ancestors to us all, Deep Ancestry shows how universal our human heritage really is. It combines sophisticated science with our compelling interest in family history and ethnic identity—and transcends humankind's shallow distinctions and superficial differences to touch the depths of our common origins.

    Europe suffered through a record freeze as the American West was hit with massive floods and snowstorms; in the western Pacific, meanwhile, some island nations literally went bone dry and had to have water flown in on transport planes.Such effects are not new: climatologists now know the El Niño and other climate anomalies have been disrupting weather patterns throughout history. But until recently, no one had asked how this new understanding of the global weather system related to archaeology and history. Droughts, floods, heat and cold put stress on cultures and force them to adapt. What determines whether they adapt successfully? How do these climate stresses affect a people's faith in the foundations of their society and the legitimacy of their rulers? How vulnerable is our own society to climate change?In this dazzlingly original new book, archaeologist Brian Fagan shows that short-term climate shifts have been a major—and hitherto unrecognized—force in history. El Niño-driven droughts have brought on the collapse of dynasties in Egypt; El Niño monsoon failures have caused historic famines in India; and El Niño floods have destroyed whole civilizations in Peru. Other short-term climate changes may have caused the mysterious abandonment of the Anasazi dwellings in the American Southwest and the collapse of the ancient Maya empire, as well as changed the course of European history.This beautifully written, groundbreaking book opens a new door on our understanding of historical events.

    They unearthed a treasure trove of Cretaceous dinosaurs and mammals, including several new species, that has already helped to reshape our understanding of the dinosaur age. In Dinosaurs of the Flaming Cliffs, team leader Michael Novacek, Provost of Science of the American Museum of Natural History and Curator of Vertebrate Paleontology, re-creates the day-to-day drama of field exploration over the past six years in the Gobi and recounts his and his colleagues' historic discoveries, reported in front-page headlines across the world. In a remarkable narrative that interweaves expedition chapters with in-depth scientific discussions on the nature and importance of the fossil record, Novacek takes us on a journey that explores the very nature of scientific inquiry and dinosaur research.

    But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.

    The fascinating story of how a harsh terrain that resembled modern Antarctica has been transformed gradually into the forests, grasslands, and wetlands we know today.

    This title shows us how to examine, study, and appreciate microbes in the manner of a birdwatcher, by making sightings of microbial activities and thereby identifying particular microbes as well as understanding what they do and how they do it.

    The new edition offers a wealth of new information, especially in the areas of taxonomy, genomics, plant hormones, and Arabidopsis research.

    Was this forest once farmland? Was it logged in the past? Was there ever a major catastrophe like a fire or a wind storm that brought trees down?Now Wessels takes that wonderful ability to discern much of the history of the forest from visual clues and boils it all down to a manageable field guide that you can take out to the woods and use to start playing forest detective yourself. Wessels has created a key—a fascinating series of either/or questions—to guide you through the process of analyzing what you see. You’ll feel like a woodland Sherlock Holmes. No walk in the woods will ever be the same.

    Illustrated with hundreds of his original photographs, Tracking & the Art of Seeing provides complete information on the behavior and habitat of over 50 animal species and shows you how to identify animals by their tracks, tail patterns, droppings, dens, scratches and other signs.

    The story spans more than forty years, following the fate of a magnificent sand dune on Lake Michigan and the people who care about it. Author and narrator Heather Shumaker shares the remarkable untold stories behind protecting land and creating new nature preserves. Written in a compelling narrative style, the book is intended in part as a case study for landscape-level conservation and documents the challenges of integrating economic livelihoods into conservation and what it really means to "preserve" land over time.This is the story of a small band of determined townspeople and how far they went to save beloved land and endangered species from the grip of a powerful corporation. Saving Arcadia is a narrative with roots as deep as the trees the community is trying to save, something set in motion before the author was even born. And yet, Shumaker gives a human face to the changing nature of land conservation in the twenty-first century. Throughout this chronicle we meet people like Elaine, a nineteen-year-old farm wife; Dori, a lakeside innkeeper; and Glen, the director of the local land trust. Together with hundreds of others they cross cultural barriers and learn to help one another in an effort to win back the six-thousand-acre landscape taken over by Consumers Power that is now facing grave devastation. The result is a triumph of community that includes working farms, local businesses, summer visitors, year-round residents, and a network of land stewards.A work of creative nonfiction, Saving Arcadia is the adventurous tale of everyday people fighting to reclaim the land that has been in their family for generations. It explores ideas about nature and community, and anyone from scholars of ecology and conservation biology to readers of naturalist writing can gain from Arcadia's story.

    At the same time as climate change has assumed this status, it has become a topic more likely to be included in a church sermon. Indeed, while once considered the concern of scientific institutions, climate change is now increasingly incorporated into faith-based initiatives with even Pope Francis weighing in, issuing an encyclical on the subject as explained in chapter 16 by Paul Driessen. There are those who believe Pope Francis, and admire another climate change exponent, Al Gore – who marketed An Inconvenient Truth with comment, ‘the fact of global warming is not in question’ and that ‘its consequences for the world we live in will be disastrous if left unchecked’. And then there are the die-hard sceptics who dare to doubt. Many claim that these climate sceptics and their support base have an undue political influence, successfully thwarting attempts to implement necessary public policy change. This book is a collection of chapters by so-called climate sceptics. Each writer was asked to write on an aspect of the topic in which they are considered to have some expertise. None of them deny that climate change is real, but instead, they point out how extremely complex the topic of Earth’s climate is, with some of the contributors also querying the, often generally accepted, solutions. As you will see, this is not a book with just one message, except perhaps that there is a need for more scrutiny of the data, and of our own prejudices. This book’s reason for being is to give pause for thought, and to throw some alternative ideas and considerations into the mix.

    Notable is the inclusion, for the first time, of four-colour photographs and illustrations throughout. Like previous editions, the book shows how evolutionary biologists analyze all aspects of behaviour.

    Since that time he has answered thousands of questions about birds, both at his store and while walking down the aisles of the supermarket. The questions have ranged from inquiries about individual species ("Are flamingos really real?") to what and when to feed birds ("Should I bring in my feeders for the summer?") to the down-and-dirty specifics of backyard birding ("Why are the birds dropping poop in my pool?"). Answering the questions has been easy; keeping a straight face has been hard.Why Don't Woodpeckers Get Headaches? is the solution for the beginning birder who already has a book that explains the slight variation between Common Ground-Doves and Ruddy Ground-Doves but who is really much more interested in why birds sing at 4:30 A.M. instead of 7:00 A.M., or whether it's okay to feed bread to birds, or how birds rediscover your feeders so quickly when you've just filled them after a long vacation. Or, for that matter, whether flamingos are really real.

    An evolutionary perspective forms the foundation of the entire discussion. The book begins with the natural history of the planet, considers portions of the whole in the middle chapters, and ends with another perspective of the entire planet in the concluding chapter. Its unique organization of focusing only on several key concepts in each chapter sets it apart from the competition. .

    Throughout these adventures, Rinella found himself contemplating his own place among the 14,000 years’ worth of buffalo hunters in North America, as well as the buffalo’s place in the American experience. At the time of the Revolutionary War, North America was home to approximately 40 million buffalo, the largest herd of big mammals on the planet, but by the mid-1890s only a few hundred remained. Now that the buffalo is on the verge of a dramatic ecological recovery across the West, Americans are faced with the challenge of how, and if, we can dare to share our land with a beast that is the embodiment of the American wilderness. American Buffalo is a narrative tale of Rinella’s hunt. But beyond that, it is the story of the many ways in which the buffalo has shaped our national identity. Rinella takes us across the continent in search of the buffalo’s past, present, and future: to the Bering Land Bridge, where scientists search for buffalo bones amid artifacts of the New World’s earliest human inhabitants; to buffalo jumps where Native Americans once ran buffalo over cliffs by the thousands; to the Detroit Carbon works, a “bone charcoal” plant that made fortunes in the late 1800s by turning millions of tons of buffalo bones into bone meal, black dye, and fine china; and even to an abattoir turned fashion mecca in Manhattan’s Meatpacking District, where a depressed buffalo named Black Diamond met his fate after serving as the model for the American nickel. Rinella’s erudition and exuberance, combined with his gift for storytelling, make him the perfect guide for a book that combines outdoor adventure with a quirky blend of facts and observations about history, biology, and the natural world. Both a captivating narrative and a book of environmental and historical significance, American Buffalo tells us as much about ourselves as Americans as it does about the creature who perhaps best of all embodies the American ethos.
