In his groundbreaking Before the Dawn, Wade reveals humanity's origins as never before--a journey made possible only recently by genetic science, whose incredible findings have answered such questions as: What was the first human language like? How large were the first societies, and how warlike were they? When did our ancestors first leave Africa, and by what route did they leave? By eloquently solving these and numerous other mysteries, Wade offers nothing less than a uniquely complete retelling of a story that began 500 centuries ago.

    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.

    If you read one book on human origins, this should be it' Ian Morris, author of Why the West Rules - For Now 'The who, what, where, when and how of human evolution, from one of the world's experts on the dating of prehistoric fossils' Steve Brusatte, author of The Rise and Fall of the Dinosaurs50,000 years ago, we were not the only species of human in the world. There were at least four others, including the Neanderthals, Homo floresiensis, Homo luzonesis and the Denisovans. At the forefront of the latter's ground-breaking discovery was Oxford Professor Tom Higham. In The World Before Us, he explains the scientific and technological advancements - in radiocarbon dating and ancient DNA, for example - that allowed each of these discoveries to be made, enabling us to be more accurate in our predictions about not just how long ago these other humans lived, but how they lived, interacted and live on in our genes today. This is the story of us, told for the first time with its full cast of characters.'The application of new genetic science to pre-history is analogous to how the telescope transformed astronomy. Tom Higham brings us to the frontier of recent discoveries with a book that is both gripping and fun' Paul Collier, author of The Bottom Billion'This exciting book shows that we now have a revolutionary new tool for reconstructing the human past: DNA from minute pieces of tooth and bone, and even from the dirt on the floor of caves' David Abulafia, author of The Boundless Sea'The remarkable new science of palaeoanthropology, from lab bench to trench' Rebecca Wragg Sykes, author of Kindred'Higham's thrilling account makes readers feel as if they were participating themselves in the extraordinary series of events that in the last few years has revealed our long-lost cousins' David Reich, author of Who We Are and How We Got Here'A brilliant distillation of the ideas and discoveries revolutionising our understanding of human evolution' Chris Gosden, author of The History of Magic

    Why We Get Sick compels readers to reexamine the age-old attitudes toward sickness. Line drawings.

    With effervescent wit, Jones argues that men, biologically speaking, are the true second sex. Here he lays out the cases for and against masculinity -- exploring every biological aspect from the genesis of the Y chromosome onward -- based on the recent explosion of biological research. Along the way, he offers pithy commentary on topics such as male hormones, hair loss, and the hydraulics of man's most intimate organ. Fascinating and often surprising, Jones's evidence offers fresh fuel for the battle of the sexes.

    Yet, according to David Sloan Wilson, the Darwinian revolution won't be truly complete until it is applied more broadly--to everything associated with the words "human," "culture," and "policy."In a series of engaging and insightful examples--from the breeding of hens to the timing of cataract surgeries to the organization of an automobile plant--Wilson shows how an evolutionary worldview provides a practical tool kit for understanding not only genetic evolution but also the fast-paced changes that are having an impact on our world and ourselves. What emerges is an incredibly empowering argument: If we can become wise managers of evolutionary processes, we can solve the problems of our age at all scales--from the efficacy of our groups to our well-being as individuals to our stewardship of the planet Earth.

    Looking at the organisms that have made all this possible gives us a new way of understanding how we got here--and perhaps of thinking about where we're going. Instead of a history of which great scientists had which great ideas, this story of passionflowers and hawkweeds, of zebra fish and viruses, offers a bird's (or rodent's) eye view of the work that makes science possible.Mixing the celebrities of genetics, like the fruit fly, with forgotten players such as the evening primrose, the book follows the unfolding history of biological inheritance from Aristotle's search for the "universal, absolute truth of fishiness" to the apparently absurd speculations of eighteenth-century natural philosophers to the spectacular findings of our day--which may prove to be the absurdities of tomorrow.The result is a quirky, enlightening, and thoroughly engaging perspective on the history of heredity and genetics, tracing the slow, uncertain path--complete with entertaining diversions and dead ends--that led us from the ancient world's understanding of inheritance to modern genetics.

    Our minds have spawned civilizations and technologies that have changed the face of the Earth, whereas even our closest animal relatives sit unobtrusively in their dwindling habitats. Yet despite longstanding debates, the nature of this apparent gap has remained unclear. What exactly is the difference between our minds and theirs? In The Gap, psychologist Thomas Suddendorf provides a definitive account of the mental qualities that separate humans from other animals, as well as how these differences arose. Drawing on two decades of research on apes, children, and human evolution, he surveys the abilities most often cited as uniquely human -- language, intelligence, morality, culture, theory of mind, and mental time travel -- and finds that two traits account for most of the ways in which our minds appear so distinct: Namely, our open-ended ability to imagine and reflect on scenarios, and our insatiable drive to link our minds together. These two traits explain how our species was able to amplify qualities that we inherited in parallel with our animal counterparts; transforming animal communication into language, memory into mental time travel, sociality into mind reading, problem solving into abstract reasoning, traditions into culture, and empathy into morality. Suddendorf concludes with the provocative suggestion that our unrivalled status may be our own creation -- and that the gap is growing wider not so much because we are becoming smarter but because we are killing off our closest intelligent animal relatives. Weaving together the latest findings in animal behavior, child development, anthropology, psychology, and neuroscience, this book will change the way we think about our place in nature. A major argument for reconsidering what makes us human, The Gap is essential reading for anyone interested in our evolutionary origins and our relationship with the rest of the animal kingdom.

    But as biologist Beth Shapiro argues in Life as We Made It, this phenomenon isn’t new. Humans have been reshaping the world around us for ages, from early dogs to modern bacteria modified to pump out insulin. Indeed, she claims, reshaping nature—resetting the course of evolution, ours and others’—is the essence of what our species does. In exploring our evolutionary and cultural history, Shapiro finds a course for the future. If we have always been changing nature to help us survive and thrive, then we need to avoid naive arguments about how we might destroy it with our meddling, and instead ask how we can meddle better. Brilliant and insightful, Life as We Made It is an essential book for the decades to come.

    The book was based on a course of public lectures delivered by Schrödinger in February 1943 at Trinity College, Dublin. Schrödinger's lecture focused on one important question: "how can the events in space and time which take place within the spatial boundary of a living organism be accounted for by physics and chemistry?" In the book, Schrödinger introduced the idea of an "aperiodic crystal" that contained genetic information in its configuration of covalent chemical bonds. In the 1950s, this idea stimulated enthusiasm for discovering the genetic molecule and would give both Francis Crick and James Watson initial inspiration in their research.

    Psychologist Geoffrey Miller offers the most convincing-and radical-explanation for how and why the human mind evolved.Consciousness, morality, creativity, language, and art: these are the traits that make us human. Scientists have traditionally explained these qualities as merely a side effect of surplus brain size, but Miller argues that they were sexual attractors, not side effects. He bases his argument on Darwin's theory of sexual selection, which until now has played second fiddle to Darwin's theory of natural selection, and draws on ideas and research from a wide range of fields, including psychology, economics, history, and pop culture. Witty, powerfully argued, and continually thought-provoking, The Mating Mind is a landmark in our understanding of our own species.

    Phages are also being used to detect and remove pathogens from our food supplies, both plant and animal. Also exciting is the use of phages as vehicles to delivery DNA vaccines, often directly to mammalian immune system cells. Recent work also suggests possible antitumor effects of phages. We stand on the edge of a whole new world of exploration and applications of microbiology.
