Silver takes a cautiously optimistic look at the scientific advances that will allow us to engineer life in ways that were unimaginable just a few short years ago—indeed, in ways that go far beyond cloning. In clear, engaging, and accessible prose, Silver demystifies the science behind a myriad of thrilling and frightening new possibilities, in a book that is essential reading for anyone who wants to understand the hopes and dilemmas of the American family in the twenty-first century.

    Random genetic mutation, long believed to be the main source of variation, is only a marginal factor. As the authors demonstrate in this book, the more important source of speciation, by far, is the acquisition of new genomes by symbiotic merger. The result of thirty years of delving into a vast, mostly arcane literature, this is the first book to go beyond -- and reveal the severe limitations of -- the "Modern Synthesis" that has dominated evolutionary biology for almost three generations. Lynn Margulis, whom E. O. Wilson called "one of the most successful synthetic thinkers in modern biology," and her co-author Dorion Sagan have written a comprehensive and scientifically supported presentation of a theory that directly challenges the assumptions we hold about the variety of the living world.

    We nevertheless muddle through even in the absence of theories of how to act. But how do we do it?In Probably Approximately Correct, computer scientist Leslie Valiant presents a masterful synthesis of learning and evolution to show how both individually and collectively we not only survive, but prosper in a world as complex as our own. The key is “probably approximately correct” algorithms, a concept Valiant developed to explain how effective behavior can be learned. The model shows that pragmatically coping with a problem can provide a satisfactory solution in the absence of any theory of the problem. After all, finding a mate does not require a theory of mating. Valiant’s theory reveals the shared computational nature of evolution and learning, and sheds light on perennial questions such as nature versus nurture and the limits of artificial intelligence.Offering a powerful and elegant model that encompasses life’s complexity, Probably Approximately Correct has profound implications for how we think about behavior, cognition, biological evolution, and the possibilities and limits of human and machine intelligence.

    As bewilderingly diverse then as the beetle is today, they survived in the arctic or the tropics, were spiky or smooth, were large as lobsters or small as fleas. And because they flourished for three hundred million years, they can be used to glimpse a less evolved world of ancient continents and vanished oceans. Erudite and entertaining, this book is a uniquely exuberant homage to a fabulously singular species.

    Andrew began his African career in the 1990s working with the late Dr Catherine Hamlin and since then has started the Barbara May Foundation, which has built hospitals, trained staff and established programs to heal fistulas and also prevent them from occurring around Africa in the world's most disadvantaged women.Two million African women are estimated to be suffering with obstetric fistulas. They are often made outcasts in their own community, unable to leave their homes and left with little prospect of a happy, fulfilling life. Andrew's operations, and the spread of fistula-skilled surgeons he is training across the continent, don't just relieve the emotional and physical pain of the women affected, but give them hope and a future.A Doctor in Africa is the uplifting story of Andrew's life, from the challenges faced along the way to the stories of the women whose lives he has forever changed.All royalties from the sale of this book will be donated to the Barbara May Foundation.Praise for A Doctor in Africa'Andrew's compassion for the women of Africa will inspire and uplift you.

This book is one of the best antidotes to despondency and doubt I have ever read.' Simon Manchester, Former Rector, St Thomas Anglican Church North Sydney'Andrew's deep connection with Africa, the land and her people is both confronting and inspiring.

    The human brain has evolved a complex circuitry that allows it to be socially intelligent. This social machinery has only just begun to be studied in detail. One function of this circuitry is to attribute awareness to others: to compute that person Y is aware of thing X. In Graziano's theory, the machinery that attributes awareness to others also attributes it to oneself. Damage that machinery and you disrupt your own awareness. Graziano discusses the science, the evidence, the philosophy, and the surprising implications of this new theory.

    In a wry manner and personal tone, Chris Lavers explores and solves some of nature's most challenging evolutionary mysteries, such as why birds are small and plentiful, why rivers and lakes are dominated by the few remaining large reptiles, why most of the large land-dwellers are mammals, and many more.

    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?
