News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    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.

    Yet The Origin of Species (1859) is also a humane and inspirational vision of ecological interrelatedness, revealing the complex mutual interdependencies between animal and plant life, climate and physical environment, and—by implication—within the human world. Written for the general reader, in a style which combines the rigour of science with the subtlety of literature, The Origin of Species remains one of the founding documents of the modern age.

    While these are essential, many young ecologists need to figure out how to actually do research themselves. How to Do Ecology provides nuts-and-bolts advice on how to develop a successful thesis and research program. This book presents different approaches to posing testable ecological questions. In particular, it covers the uses, strengths, and limitations of manipulative experiments in ecology. It will help young ecologists consider meaningful treatments, controls, replication, independence, and randomization in experiments, as well as where to do experiments and how to organize a season of work. This book also presents strategies for analyzing natural patterns, the value of alternative hypotheses, and what to do with negative results.Science is only part of being a successful ecologist. This engagingly written book offers students advice on working with other people and navigating their way through the land mines of research. Findings that don't get communicated are of little value. How to Do Ecology suggests effective ways to communicate information in the form of journal articles, oral presentations, and posters. Finally, it outlines strategies for developing successful grant and research proposals. Numerous checklists, figures, and boxes throughout the book summarize and reinforce the main points. In short, this book makes explicit many of the unspoken assumptions behind doing good research in ecology, and provides an invaluable resource for meaningful conversations among ecologists.

    Only seven of these are responsible for creating the world's sweetest treat—honey. Combining Ilona's gorgeous photography and E. Readicker-Henderson's engaging text, A Short History of the Honey Bee follows the journey from flower to hive to honey throughout history.A Short History of the Honey Bee starts with the story of the honey bee—why it is named Apis mellifera, how it has evolved from a solitary creature to one that travels in groups, why it stings, and how pollination really works. Readicker-Henderson then moves on to the honey, detailing its history from a wild food foraged for on cliffs to the many varieties available for purchase today. But it is the everyday importance of the bee that remains the central message. Forty percent of the world's food supply—including apples, tomatoes, and strawberries—is dependent on pollination by honeybees. Colony collapse, when the worker bees suddenly disappear and leave behind the queen and the hive, is an ecological and agricultural crisis. For this reason alone we need to be more aware of the significance of bees.

    Bird-eating snakes from Australia hitchhike to Hawaii in the landing gear of airliners; disruptive European zebra mussels, riding in ships' ballast water, are infiltrating aquatic ecosystems across the United States; parasitic flies from the U.S. prey on Darwin's finches in the Galapagos. Predatory American jellyfish in Russia; toxic Japanese plankton in Australia; Burmese pythons in the Everglades-biologists refer fearfully to "the homogenization of the world" as alien species jump from place to place and increasingly crowd native and endangered species out of existence. Never mind bulldozers and pesticides: the fastest-growing threat to biological diversity may be nature itself. "Out of Eden" is a journey through this strange and shifting landscape. The author tours the front lines of ecological invasion--in Hawaii, Tasmania, Guam, San Francisco; in lush rainforests, through underground lava tubes, on the deck of an Alaska-bound oil tanker--in the company of world-class scientists. Wry and reflective, animated and richly reported, "Out of Eden" is a search both for scientific answers and for ecological authenticity.

    Beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in the sequencing of the Neanderthal genome in 2010, Neanderthal Man describes the events, intrigues, failures, and triumphs of these scientifically rich years through the lens of the pioneer and inventor of the field of ancient DNA.We learn that Neanderthal genes offer a unique window into the lives of our hominin relatives and may hold the key to unlocking the mystery of why humans survived while Neanderthals went extinct. Drawing on genetic and fossil clues, Pääbo explores what is known about the origin of modern humans and their relationship to the Neanderthals and describes the fierce debate surrounding the nature of the two species’ interactions. His findings have not only redrawn our family tree, but recast the fundamentals of human history—the biological beginnings of fully modern Homo sapiens, the direct ancestors of all people alive today.A riveting story about a visionary researcher and the nature of scientific inquiry, Neanderthal Man offers rich insight into the fundamental question of who we are.

    In this beautiful new one-volume edition, modern readers are introduced to one of the best nature writers of the last century. More than one hundred of the original illustrations by Paul Landacre highlight the eloquent and entertaining accounts of American trees. As we read Peattie's descriptions, we catch glimpses of our country's history and past daily life that no textbook could ever illuminate so vividly.Here you'll learn about everything from how a species was discovered to the part it played in our country’s history. Pioneers often stabled an animal in the hollow heart of an old sycamore, and the whole family might live there until they could build a log cabin. The tuliptree, the tallest native hardwood, is easier to work than most softwood trees; Daniel Boone carved a sixty-foot canoe from one tree to carry his family from Kentucky into Spanish territory. In the days before the Revolution, the British and the colonists waged an undeclared war over New England's white pines, which made the best tall masts for fighting ships. It's fascinating to learn about the commercial uses of various woods -- for paper, fine furniture, fence posts, matchsticks, house framing, airplane wings, and dozens of other preplastic uses. But we cannot read this book without the occasional lump in our throats. The American elm was still alive when Peattie wrote, but as we read his account today we can see what caused its demise. Audubon's portrait of a pair of loving passenger pigeons in an American beech is considered by many to be his greatest painting. It certainly touched the poet in Donald Culross Peattie as he depicted the extinction of the passenger pigeon when the beech forest was destroyed. A Natural History of North American Trees gives us a picture of life in America from its earliest days to the middle of the last century. The information is always interesting, though often heartbreaking. While Peattie looks for the better side of man's nature, he reports sorrowfully on the greed and waste that have doomed so much of America's virgin forest.

    It is a hands-on guide to learning about the natural environment of California. Subjects covered include California natural history and geology, native plants and animals, California's freshwater resources and ecosystems, forest and rangeland resources, conservation biology, and the effects of global warming on California's natural communities. The Handbook also discusses how to create and use a field notebook, natural resource interpretation, citizen science, and collaborative conservation and serves as the primary text for the California Naturalist Program.

    Ehrlich, author of The Dominant Animal  Biologist Rob Dunn’s Every Little Thing is the story of man’s obsessive quest to catalog life, from nanobacteria to new monkeys. In the tradition of E.O. Wilson, this engaging and fascinating work of popular science follows humanity’s unending quest to discover every living thing in our natural world—from the unimaginably small in the most inhospitable of places on earth to the unimaginably far away in the unexplored canals on Mars.

    They have brains that are huge for their body size and exhibit an avian kind of eloquence. They mate for life and associate with relatives and neighbors for years. And because they often live near people—in our gardens, parks, and cities—they are also keenly aware of our peculiarities, staying away from and even scolding anyone who threatens or harms them and quickly learning to recognize and approach those who care for and feed them, even giving them numerous, oddly touching gifts in return. With his extraordinary research on the intelligence and startling abilities of corvids—crows, ravens, and jays—scientist John Marzluff teams up with artist-naturalist Tony Angell to tell amazing stories of these brilliant birds in Gifts of the Crow. With narrative, diagrams, and gorgeous line drawings, they offer an in-depth look at these complex creatures and our shared behaviors. The ongoing connection between humans and crows—a cultural coevolution—has shaped both species for millions of years. And the characteristics of crows that allow this symbiotic relationship are language, delinquency, frolic, passion, wrath, risk-taking, and awareness—seven traits that humans find strangely familiar. Crows gather around their dead, warn of impending doom, recognize people, commit murder of other crows, lure fish and birds to their death, swill coffee, drink beer, turn on lights to stay warm, design and use tools, use cars as nutcrackers, windsurf and sled to play, and work in tandem to spray soft cheese out of a can. Their marvelous brains allow them to think, plan, and reconsider their actions. With its abundance of funny, awe-inspiring, and poignant stories, Gifts of the Crow portrays creatures who are nothing short of amazing. A testament to years of painstaking research and careful observation, this fully illustrated, riveting work is a thrilling look at one of nature’s most wondrous creatures.

    The second half of the nineteenth century -- the so-called Gilded Age -- was a time when Americans were exploring the West and building a nation that would stretch from coast to coast.It was also a time of scientific ferment. Charles Darwin had shaken the very foundations of Victorian society with his theory of evolution by natural selection, and scientists across the civilized world were locked in a great battle over Darwin's idea. While the debate raged in Europe, the hunt for hard evidence increasingly focused on the American West, with its grand mesas, buttes, and badlands. "We must turn to the New World if we wish to see in perfection the oldest monuments of earth's history," advised Sir Charles Lyell, the father of modern geology, after a visit to America. "Certainly in no other country are these ancient strata developed on a grander scale or more plentifully charged with fossils."Could the answer to the history of life and the proof of evolution be found in those fossils? That was the question that two young American paleontologists--Edward Drinker Cope and Othniel Charles Marsh--set out to answer. But what began as a friendly contest quickly turned into bitter rivalry that would spill over into American science and politics and rage relentlessly for nearly three decades.        Cope and Marsh would battle on the prairies, in the halls of Congress, in science journals, and in the popular press. Both wealthy men, they launched lavish, western expeditions and raced across the plains and mountains searching for the remains of the magnificent beasts that once inhabited the continent. Along the way they would encounter George Custer, Sitting Bull, Buffalo Bill, and Red Cloud.         Among the most remarkable fossil discoveries of Cope and Marsh are a bevy of dinosaurs, including some of the best known beasts -- the Triceratops, the Stegosaurus, the Camarasaurus, and the Brontosaurus. Even today, Marsh holds the record for dinosaur discoveries.        Just as valuable, however, were some of Marsh's discoveries of ancient mammals and birds that provided the first real proof of Dar- win's theory--"The best support for the theory in twenty years," the great Darwin himself proclaimed.        The tale of Cope and Marsh is also the story of the rise of American science. When their story begins just after the Civil War, America was an intellectual backwater, with eminent scientists snookered by the great, fake stone statue The Cardiff Giant--a hoax unmasked by Marsh.        But even as Cope and Marsh waged war, they both fought to build up American science and its scientific institutions. Yet despite their discoveries and their Gilded Age celebrity, the names of Cope and Marsh have faded into the recesses of the library and archive. In The Gilded Dinosaur Mark Jaffe exhumes from those archives the notes, journals, and letters of Cope and Marsh to reanimate and retell one of the keenest rivalries in the history of science.

    The only rock we eat, salt has shaped civilization from the very beginning, and its story is a glittering, often surprising part of the history of humankind. A substance so valuable it served as currency, salt has influenced the establishment of trade routes and cities, provoked and financed wars, secured empires, and inspired revolutions.

    . . a book that enriches our understanding of how the struggle to think new thoughts is shared across time and space and people.”—The Sunday Telegraph (London)Christmas, 1859. Just one month after the publication of On the Origin of Species, Charles Darwin received an unsettling letter. He had expected criticism; in fact, letters were arriving daily, most expressing outrage and accusations of heresy. But this letter was different. It accused him of failing to acknowledge his predecessors, of taking credit for a theory that had already been discovered by others. Darwin realized that he had made an error in omitting from Origin of Species any mention of his intellectual forebears. Yet when he tried to trace all of the natural philosophers who had laid the groundwork for his theory, he found that history had already forgotten many of them.Darwin’s Ghosts tells the story of the collective discovery of evolution, from Aristotle, walking the shores of Lesbos with his pupils, to Al-Jahiz, an Arab writer in the first century, from Leonardo da Vinci, searching for fossils in the mine shafts of the Tuscan hills, to Denis Diderot in Paris, exploring the origins of species while under the surveillance of the secret police, and the brilliant naturalists of the Jardin de Plantes, finding evidence for evolutionary change in the natural history collections stolen during the Napoleonic wars. Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature’s extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.With each chapter focusing on an early evolutionary thinker, Darwin’s Ghosts is a fascinating account of a diverse group of individuals who, despite the very real dangers of challenging a system in which everything was presumed to have been created perfectly by God, felt compelled to understand where we came from. Ultimately, Stott demonstrates, ideas—including evolution itself—evolve just as animals and plants do, by intermingling, toppling weaker notions, and developing over stretches of time. Darwin’s Ghosts presents a groundbreaking new theory of an idea that has changed our very understanding of who we are.
