    In this thrill-ride across millennia and continents, the complete history of the planet comes to life: from the Earth's fiery birth to its near-obliteration in the Triassic period, and from the first signs of human life to the tentative future of a world with a burgeoning population and a global warming crisis. Covering a wide range of topics including astrophysics, zoology, and sociology, and complete with maps and illustrations, What on Earth Happened? In Brief is the endlessly entertaining story of the planet, life, and people.

    He also happens to have a Ph.D. in zoology and wrote his dissertation on evolution, atheism and naturalism. Preston Jones is a history professor at a Christian college and a fan of Bad Religion's music. One day, on a whim, Preston sent Greg an appreciative e-mail. That was the start of an extraordinary correspondence. For several months, Preston and Greg sent e-mails back and forth on big topics like God, religion, knowledge, evil, evolution, biology, destiny and the nature of reality. Preston believes in God; Greg sees insufficient evidence for God's existence. Over the course of their friendly debate, they tackle such cosmic questions as: Is religion rational or irrational? Does morality require belief in God? Do people only believe in God because they are genetically predisposed toward religion? How do you make sense of suffering in the world? Is this universe all there is? And what does it all matter? In this engaging book, Preston and Greg's actual e-mail correspondence is reproduced, along with bonus materials that provide additional background and context. Each makes his case for why he thinks his worldview is more compelling and explanatory. While they find some places to agree, neither one convinces the other. They can't both be right. So which worldview is more plausible? You decide.

    

    Soon Gen Xers will be the only cohort of Americans who remember life as it was lived before the arrival of the Internet. They are, as Hennessey dubs them, “the last adult generation,” the sole remaining link to a time when childhood was still a bit dangerous but produced adults who were naturally resilient. More than a decade into the social media revolution, the American public is waking up to the idea that the tech sector’s intentions might not be as pure as advertised. The mountains of money being made off our browsing habits and purchase histories are used to fund ever-more extravagant and utopian projects that, by their very natures, will corrode the foundations of free society, leaving us all helpless and digitally enslaved to an elite crew of ultra-sophisticated tech geniuses. But it’s not too late to turn the tide. There’s still time for Gen X to write its own future. A spirited defense of free speech, eye contact, and the virtues of patience, Zero Hour for Gen X is a cultural history of the last 35 years, an analysis of the current social and historical moment, and a generational call to arms.

    

    It is a hands-on guide to learning about the natural environment of California. Subjects covered include California natural history and geology, native plants and animals, California's freshwater resources and ecosystems, forest and rangeland resources, conservation biology, and the effects of global warming on California's natural communities. The Handbook also discusses how to create and use a field notebook, natural resource interpretation, citizen science, and collaborative conservation and serves as the primary text for the California Naturalist Program.

    Its geology, its unique flora and fauna, and its striking role in human history intersect in surprising and dynamic ways. This book is the most wide-ranging and beautifully illustrated book available on the famous islands. Not since Darwin’s Naturalist’s Voyage has a book combined so much scientific and historic information with firsthand accounts that bring the Galápagos to life.Galápagos: The Islands That Changed the World describes how tragedy and murderous pirates curtailed settlement of the islands and how the islands’ pristine nature, spectacular geology, and defining isolation inspired Darwin’s ideas about evolution. The book explores the diverse land and marine habitats that shelter Galápagos species and considers the islands’ importance today as a frontier for science and a refuge for true wilderness. The book’s extensive gazetteer provides details about endemic plants and animals as well as travel advice about visitors’ sites, diving, photography, when to go, and what to take. Vividly illustrated throughout, this guide is an indispensable reference for natural history enthusiasts, armchair travelers, and island visitors alike.

    McPhee embarks on a fascinating journey across the basement of the continent -- the land masses forming Illinois, Iowa, Nebraska, and thereabouts -- with a professor and geochronologist acting as a guide.

    In addition to fieldwork and traditional methods, paleoanthropologists and archaeologists now draw upon genetics and other cutting-edge scientific techniques. In fifty chapters, Prehistoric Investigations tells the story of the many thought-provoking discoveries that have transformed our understanding of the distant past.

    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.

    He shows that there are many ways of achieving happiness; for example, there is the inherent happiness that comes with the love of a child; the competitive happiness of triumphing over your opponents; the sensual happiness of the hedonist. Rather than preaching a particular behavior or way of life, Morris provides knowledge that we can use, if we wish, to make ourselves happier.
