For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of proteins. Other regions - 98% of the human genome - were dismissed as 'junk'. But in recent years researchers have discovered that variations in this 'junk' DNA underlie many previously intractable diseases, and they can now generate new approaches to tackling them. Nessa Carey explores, for the first time for a general audience, the incredible story behind a controversy that has generated unusually vituperative public exchanges between scientists. She shows how junk DNA plays an important role in areas as diverse as genetic diseases, viral infections, sex determination in mammals, human biological complexity, disease treatments, even evolution itself - and reveals how we are only now truly unlocking its secrets, more than half a century after Crick and Watson won their Nobel prize for the discovery of the structure of DNA in 1962.

    James Cleaves II seek to answer the most crucial question in science: How did life begin? They trace the trials and triumphs of the iconoclastic scientists who have sought to solve the mystery, from Darwin’s theory of evolution to Crick and Watson’s unveiling of DNA. This fascinating exploration not only examines the origin-of-life question, but also interrogates the very nature of scientific discovery and objectivity.

    While we may take our air for granted, Earth was not always an oxygenated planet. How did it become this way? "Oxygen" is the most current account of the history of atmospheric oxygen on Earth. Donald Canfield--one of the world's leading authorities on geochemistry, earth history, and the early oceans--covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of the Earth. With an accessible and colorful first-person narrative, he draws from a variety of fields, including geology, paleontology, geochemistry, biochemistry, animal physiology, and microbiology, to explain why our oxygenated Earth became the ideal place for life.Describing which processes, both biological and geological, act to control oxygen levels in the atmosphere, Canfield traces the records of oxygen concentrations through time. Readers learn about the great oxidation event, the tipping point 2.3 billion years ago when the oxygen content of the Earth increased dramatically, and Canfield examines how oxygenation created a favorable environment for the evolution of large animals. He guides readers through the various lines of scientific evidence, considers some of the wrong turns and dead ends along the way, and highlights the scientists and researchers who have made key discoveries in the field.Showing how Earth's atmosphere developed over time, "Oxygen" takes readers on a remarkable journey through the history of the oxygenation of our planet.

    McKibben's argument that the survival of the globe is dependent on a fundamental, philosophical shift in the way we relate to nature is more relevant than ever. McKibben writes of our earth's environmental cataclysm, addressing such core issues as the greenhouse effect, acid rain, and the depletion of the ozone layer. His new introduction addresses some of the latest environmental issues that have risen during the 1990s. The book also includes an invaluable new appendix of facts and figures that surveys the progress of the environmental movement.More than simply a handbook for survival or a doomsday catalog of scientific prediction, this classic, soulful lament on Nature is required reading for nature enthusiasts, activists, and concerned citizens alike.

    In Resurrection Science, journalist M. R. O'Connor explores the extreme measures scientists are taking to try and save them, from captive breeding and genetic management to de-extinction. Paradoxically, the more we intervene to save species, the less wild they often become. In stories of sixteenth-century galleon excavations, panther-tracking in Florida swamps, ancient African rainforests, Neanderthal tool-making, and cryogenic DNA banks, O'Connor investigates the philosophical questions of an age in which we play god with earth's biodiversity.Each chapter in this beautifully written book focuses on a unique species--from the charismatic northern white rhinoceros to the infamous passenger pigeon--and the people entwined in the animals' fates. Incorporating natural history and evolutionary biology with conversations with eminent ethicists, O'Connor's narrative goes to the heart of the human enterprise: What should we preserve of wilderness as we hurtle toward a future in which technology is present in nearly every aspect of our lives? How can we co-exist with species when our existence and their survival appear to be pitted against one another?

    Anthropologist and naturalist, Dr. Eiseley reveals life's endless mysteries in his own experiences, departing from their immediacy into meditations on the long past, wandering—intimate with nature—along the paths and byways of time, and then returning to the present.

    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.

    Using this example as a springboard, David M. Raup leaps into an egaging discussion of the theories, assumptions, and difficulties associated with the science of species extinction. Woven is along the way are stories of the trilobite eye, tropical reefs, flying reptiles, and the fate of the heath hen on Martha's Vineyard, a very modern extinction.

    Honey bees, and the daily workings of their close-knit colonies, are one of nature's great miracles. And they produce one of nature's greatest edible bounties: honey. More than just a palate pleaser, honey was once an offering to the gods, a preservative, and a medicine whose sought-after curative powers were detailed in ancient texts . . . and are being rediscovered by modern medical science.In Letters from the Hive, Prof. Stephen Buchmann takes us into the hive--nursery, honey factory, queen's inner sanctum--and out to the world of backyard gardens, open fields, and deserts in full bloom, where the age-old sexual dance between flowers and bees makes life on earth as we know it possible. Hailed for their hard work, harmonious society, and, mistakenly, for their celibacy, bees have a link to our species that goes beyond biology. In Letters from the Hive, Buchmann explores the fascinating role of bees in human culture and mythology, following the "honey hunters" of native cultures in Malaysia, the Himalayas, and the Australian Outback as they risk life and limb to locate a treasure as valuable as any gold.To contemplate a world without bees is to imagine a desolate place, culturally and biologically, and Buchmann shows how with each acre of land sacrificed to plow, parking lot, or shopping mall, we inch closer to what could become a chilling reality. He also offers honey-based recipes, cooking tips, and home remedies--further evidence of the gifts these creatures have bestowed on us.Told with wit, wisdom, and affection, and rich with anecdote and science, Letters from the Hive is nature writing at its best. This is natural history to be treasured, a sweet tribute that buzzes with life.From the Hardcover edition.

    Here and there, we can supplement these meager scraps by the use of biochemical markers or geochemical signatures that add useful information, but, even with such additional help, our reconstructions and our models of descent are often tentative. For the fossil record is, as we have seen, as biased as it is incomplete. But fragmentary, selective, and biased though it is, the fossil record, with all its imperfections, is still a treasure. Though whole chapters are missing, many pages lost, and the earliest pages so damaged as to be, as yet, virtually unreadable, this--the greatest biography of all--is one in whose closing pages we find ourselves.--from OriginsIn Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.Rhodes's accessible and extensively illustrated treatment of the origins narrative describes the nature of the search for prehistoric life, the significance of geologic time, the origin of life, the emergence and spread of flora and fauna, the evolution of primates, and the emergence of modern humans.

    With the addition of new chapters, thorough updating, and a new co-author, this latest edition represents the definitive introduction to behavioral genetics: the crossroads where the fields of psychology, psychiatry, and genetics intersect.

    Yet, the metaphor has lodged itself in the contemporary imagination, and new fossil discoveries are often hailed in headlines as revealing the elusive transitional step, the moment when we stopped being “animal” and started being “human.” In The Accidental Species, Henry Gee, longtime paleontology editor at Nature, takes aim at this misleading notion, arguing that it reflects a profound misunderstanding of how evolution works and, when applied to the evolution of our own species, supports mistaken ideas about our own place in the universe. Gee presents a robust and stark challenge to our tendency to see ourselves as the acme of creation. Far from being a quirk of religious fundamentalism, human exceptionalism, Gee argues, is an error that also infects scientific thought. Touring the many features of human beings that have recurrently been used to distinguish us from the rest of the animal world, Gee shows that our evolutionary outcome is one possibility among many, one that owes more to chance than to an organized progression to supremacy. He starts with bipedality, which he shows could have arisen entirely by accident, as a by-product of sexual selection, moves on to technology, large brain size, intelligence, language, and, finally, sentience. He reveals each of these attributes to be alive and well throughout the animal world—they are not, indeed, unique to our species. The Accidental Species combines Gee’s firsthand experience on the editorial side of many incredible paleontological findings with healthy skepticism and humor to create a book that aims to overturn popular thinking on human evolution—the key is not what’s missing, but how we’re linked.

    Primates and cetaceans, at first they appear very different. Yet both are large brained, intelligent mammals who exhibit complex communication and social patterns. This book studies these animals side by side and comes up with some perhaps surprising results, which teach us about another large brained mammal, man.

    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.

    The discovery initiated Gessen into a club of sorts: the small (but exponentially expanding) group of people in possession of a new and different way of knowing themselves through what is inscribed in the strands of their DNA. As she wrestled with a wrenching personal decision—what to do with such knowledge—Gessen explored the landscape of this brave new world, speaking with others like her and with experts including medical researchers, historians, and religious thinkers. Blood Matters is a much-needed field guide to this unfamiliar and unsettling territory. It explores the way genetic information is shaping the decisions we make, not only about our physical and emotional health but about whom we marry, the children we bear, even the personality traits we long to have. And it helps us come to terms with the radical transformation that genetic information is engineering in our most basic sense of who we are and what we might become.
