But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    Today, more than sixty years later, members of a new generation of scientists are attempting to create life from the ground up. Science has moved forward in leaps and bounds since Schrodinger's time, but our understanding of what does and does not constitute life has only grown more complex. An era that has already seen computer chip-implanted human brains, genetically engineered organisms, genetically modified foods, cloned mammals, and brain-dead humans kept alive by machines is one that demands fresh thinking about the concept of life. While a segment of our national debate remains stubbornly mired in moral quandaries over abortion, euthanasia, and other right to life issues, the science writer Ed Regis demonstrates how science can and does provide us with a detailed understanding of the nature of life. Written in a lively and accessible style, and synthesizing a wide range of contemporary research, What Is Life? is a brief and illuminating contribution to an age-old debate.

    Presenting details about the parts of the skull (including the cranium, the mandible, the shape and positioning of the eye sockets, and species-specific features like horns, teeth, beaks and bills), information about the science and pseudoscience of skulls, and a look at skulls in religion, art and popular culture, his stories and information are riveting and enlightening.At the center of "Skulls" is a stunning, never-before-seen-in-any-capacity, visual array of the skulls of more than 300 animals that walk, swim, and fly. The skulls are from the collection of Alan Dudley, a British collector and owner of what is probably the largest and most complete private collection of skulls in the world. Every skull is beautifully photographed to show several angles and to give the reader the most intimate view possible. Each includes a short explanatory paragraph and a data box with information on the animal's taxonomy, behavior, and diet."Skulls "was published in December 2011 as an e-book for the iPad by the innovative e-book publishers Touch Press, creators of the best-selling e-books for iPad "The Elements" and "Solar System." Both books were also published in print by Black Dog & Leventhal.

    A Race Too Far is the story of how the race unfolded, and how it became a tragedy for many involved.Of the nine sailors who started the race, four realised the madness of the undertaking and pulled out within weeks. The remaining five each have their own remarkable story. Chay Blyth, fresh from rowing the Atlantic with John Ridgway, had no sailing experience but managed to sail round the Cape of Good Hope before retiring. Nigel Tetley sank whilst in the lead with 1,100 nautical miles to go, surviving but dying in tragic circumstances two years later. Donald Crowhurst began showing signs of mental illness and tried to fake a round the world voyage. His boat was discovered adrift in an apparent suicide, but his body was never found. Bernard Moitessier abandoned the race whilst in a strong position and carried on to Tahiti, where he settled and fathered a child by a local woman despite having a wife and family in Paris. Robin Knox-Johnston was the only one to complete the race.It has undoubtedly become the most legendary of modern stories of men pitting themselves against the sea. Forty years on, Chris Eakin recreates the drama of the epic race, talking to all those touched by the tragedies surrounding the Golden Globe: the survivors, the widows and the children of those who died. It is a book that both evokes the primary wonder of the adventure itself and reflects on what it has come to mean to both those involved and the rest of us in the forty years since.

    Situating these fascinating animals in a broad ecological and evolutionary context, leading dinosaur expert Scott D. Sampson fills us in on the exhilarating discoveries of the past twenty-five years, the most active period in the history of dinosaur paleontology, during which more “new” species were named than in all prior history. With these discoveries—and the most recent controversies—in mind, Sampson reconstructs the odyssey of the dinosaurs from their humble origins on the supercontinent Pangaea, to their reign as the largest animals the planet has ever known, and finally to their abrupt demise. Much more than the story of who ate whom way back when, Dinosaur Odyssey places dinosaurs in an expansive web of relationships with other organisms and demonstrates how they provide a powerful lens through which to observe the entire natural world. Addressing topics such as extinction, global warming, and energy flow, Dinosaur Odyssey finds that the dinosaurs' story is, in fact, a major chapter in our own story.

    She is perhaps the best known and most studied fossil hominid of the twentieth century, the benchmark by which other discoveries of human ancestors are judged.”–From Lucy’s LegacyIn his New York Times bestseller, Lucy: The Beginnings of Humankind, renowned paleoanthropologist Donald Johanson told the incredible story of his discovery of a partial female skeleton that revolutionized the study of human origins. Lucy literally changed our understanding of our world and who we come from. Since that dramatic find in 1974, there has been heated debate and–most important–more groundbreaking discoveries that have further transformed our understanding of when and how humans evolved. In Lucy’s Legacy, Johanson takes readers on a fascinating tour of the last three decades of study–the most exciting period of paleoanthropologic investigation thus far. In that time, Johanson and his colleagues have uncovered a total of 363 specimens of Australopithecus afarensis (Lucy’s species, a transitional creature between apes and humans), spanning 400,000 years. As a result, we now have a unique fossil record of one branch of our family tree–that family being humanity–a tree that is believed to date back a staggering 7 million years.Focusing on dramatic new fossil finds and breakthrough advances in DNA research, Johanson provides the latest answers that post-Lucy paleoanthropologists are finding to questions such as: How did Homo sapiens evolve? When and where did our species originate? What separates hominids from the apes? What was the nature of Neandertal and modern human encounters? What mysteries about human evolution remain to be solved?Donald Johanson is a passionate guide on an extraordinary journey from the ancient landscape of Hadar, Ethiopia–where Lucy was unearthed and where many other exciting fossil discoveries have since been made–to a seaside cave in South Africa that once sheltered early members of our own species, and many other significant sites. Thirty-five years after Lucy, Johanson continues to enthusiastically probe the origins of our species and what it means to be human.
