This text has invited more than 4 million students into the study of this dynamic and essential discipline.The authors have restructured each chapter around a conceptual framework of five or six big ideas. An Overview draws students in and sets the stage for the rest of the chapter, each numbered Concept Head announces the beginning of a new concept, and Concept Check questions at the end of each chapter encourage students to assess their mastery of a given concept. New Inquiry Figures focus students on the experimental process, and new Research Method Figures illustrate important techniques in biology. Each chapter ends with a Scientific Inquiry Question that asks students to apply scientific investigation skills to the content of the chapter.

    Current estimates suggest that the rate of extinction is now thousands of times that counted in the fossil record before the emergence of modern man. At the same time, human societies themselves are in a cultural extinction crisis, with experts anticipating that of the world's nearly seven thousand languages as few as ten percent may survive into the next century. Melanie Challenger's extraordinary book is an exploration of how we might live to resist these extinctions and why such disappearances must be of concern to us. Adventurous, curious and passionate about her subject, Challenger takes us on a very personal journey as she tries to restore her own relationship with nature. The narrative unfolds through a series of landscapes haunted by extinction. From the ruined tin mines of Cornwall and the abandoned whaling stations of South Georgia to the Inuit camps of the Arctic and the white heart of Antarctica, she probes the critical relationship between human activities and environmental collapse. This is the first book to weave together the strands of cultural, biological and industrial extinctions into a meditation on the way we live beside nature in the modern world.

    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.

    Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we've come to accept as fact. In Cannibalism: A Perfectly Natural History, zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism's role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona's Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother's skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own.Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

    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.

    Weaving together history, science, and the latest theories of artificial intelligence, Lynch and Granger demystify the complexities of our brains, and show us how our memory, cognition, and intelligence actually function, as well as what mechanisms in the brain can potentially be enhanced, improving on the current design. Author of The Emotional Brain, Joseph LeDoux praised it as "provocative and fascinating," and, writing in the New Scientist, Willian Calvin called it "a popular account of how brains enlarge, in both evolutionary and developmental terms" and "a much needed book."

    Dian Fossey, a few years prior to her gruesome murder. Drawn to the adventure and promise of learning the science of studying mountain gorillas amid the beauty of Central Africa’s cloud forest, Fowler soon learns the cold harsh realities of life inside Fossey’s enclave ten thousand feet up in the Virunga Volcanoes.Instead of the intrepid scientist he had admired in the pages of National Geographic, Fowler finds a chain-smoking, hard-drinking woman bullying her staff into submission. While pressures mount from powers beyond Karisoke in an effort to extricate Fossey from her domain of thirteen years, she brings new students in to serve her most pressing need—to hang on to the remote research camp that has become her mountain home. Increasingly bizarre behavior has targeted Fossey for extrication by an ever-growing group of detractors—from conservation and research organizations to the Rwandan government.Amid the turmoil, Fowler must abandon his own research assignments to assuage the troubled Fossey as she orders him on illegal treks across the border into Zaire, over volcanoes, in search of missing gorillas, and to serve as surrogate parent to an orphaned baby ape in preparation for its traumatic re-introduction into a wild gorilla group.This riveting story is the only first-person account from inside Dian Fossey’s beleaguered camp. Fowler must come to grips with his own aspirations, career objectives, and disappointments as he develops the physical endurance to keep up with mountain gorillas over volcanic terrain in icy downpours above ten thousand feet, only to be affronted by the frightening charges of indignant giant silverbacks or to be treed by aggressive forest buffalos. Back in camp, he must nurture the sensitivity and patience needed for the demands of rehabilitating an orphaned baby gorilla.A Forest in the Clouds takes the armchair adventurer on a journey into an extraordinary world that now only exists in the memories of the very few who knew it.

    In Europe: A Natural History, world-renowned scientist, explorer, and conservationist Tim Flannery applies the eloquent interdisciplinary approach he used in his ecological histories of Australia and North America to the story of Europe. He begins 100 million years ago, when the continents of Asia, North America, and Africa interacted to create an island archipelago that would later become the Europe we know today. It was on these ancient tropical lands that the first distinctly European organisms evolved. Flannery teaches us about Europe's midwife toad, which has endured since the continent's beginning, while elephants, crocodiles, and giant sharks have come and gone. He explores the monumental changes wrought by the devastating comet strike and shows how rapid atmospheric shifts transformed the European archipelago into a single landmass during the Eocene.As the story moves through millions of years of evolutionary history, Flannery eventually turns to our own species, describing the immense impact humans had on the continent's flora and fauna--within 30,000 years of our arrival in Europe, the woolly rhino, the cave bear, and the giant elk, among others, would disappear completely. The story continues right up to the present, as Flannery describes Europe's leading role in wildlife restoration, and then looks ahead to ponder the continent's future: with advancements in gene editing technology, European scientists are working to recreate some of the continent's lost creatures, such as the great ox of Europe's primeval forests and even the woolly mammoth.Written with Flannery's characteristic combination of elegant prose and scientific expertise, Europe: A Natural History narrates the dramatic natural history and dynamic evolution of one of the most influential places on Earth.

    Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In prose that is at once frank, entertaining, and deeply informed, The New Yorker writer Elizabeth Kolbert tells us why and how human beings have altered life on the planet in a way no species has before. Interweaving research in half a dozen disciplines, descriptions of the fascinating species that have already been lost, and the history of extinction as a concept, Kolbert provides a moving and comprehensive account of the disappearances occurring before our very eyes. She shows that the sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

    On her travels she has witnessed some of the daunting and brutal challenges our ancestors had to face: mountains, deserts, oceans, changing climates, terrifying giant beasts and volcanoes. But she discovers that perhaps the most serious threat of all came from other humans. When our ancestors set out from Africa there were already two other species of human on the planet: Neanderthal in Europe and Homo erectus in Asia. Both (contrary to popular perception) were intelligent, adept at making tools and weapons and were long adapted to their environments. So, Alice asks, why did only Homo sapiens survive? Part detective story, part travelogue, and drawing on the latest genetic and archaeological discoveries, Alice examines how our ancestors evolved physically in response to these challenges, finding out how our colour, shape, size, diet, disease resistance and even athletic ability have been shaped by the range of environments that our ancestors had to survive. She also relates how astonishingly closely related we all are.

    A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science—and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. Witty, playful, and daring, this book will revolutionize our understanding of sexuality.Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.

    His previous books, including the Pulitzer Prize finalist The Blank Slate, have catapulted him into the limelight as one of today's most important and popular science writers. Now, in The Stuff of Thought, Pinker marries two of the subjects he knows best: language and human nature. The result is a fascinating look at how our words explain our nature. What does swearing reveal about our emotions? Why does innuendo disclose something about relationships? Pinker reveals how our use of prepositions and tenses taps into peculiarly human concepts of space and time, and how our nouns and verbs speak to our notions of matter. Even the names we give our babies have important things to say about our relations to our children and to society. With his signature wit and style, Pinker takes on scientific questions like whether language affects thought, as well as forays into everyday life: why is bulk e-mail called spam and how do romantic comedies get such mileage out of the ambiguities of dating? The Stuff of Thought is a brilliantly crafted and highly readable work that will appeal to fans of readers of everything from The Selfish Gene and Blink to Eats, Shoots & Leaves.

    But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the south-east United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea. Everywhere is the deep imprint of the planetary on the human.From the cultivation of the first crops to the founding of modern states, Origins reveals the breathtaking impact of the earth beneath our feet on the shape of our human civilizations.

    Following in the fashion of Stephen Jay Gould and Peter Medawar, one of the world's leading scientists examines how "pure science" is in fact shaped and guided by social and political needs and assumptions.
