In its structure and content, the Anthology is intended to complement the Companion to Bioethics, edited by the same scholars. The Anthology is independent of any particular approach to bioethics. Can be used as a source book to complement the Companion to Bioethics. Probes more deeply than the standard anthologies into the foundations of bioethics. More global in approach than competition.

    Already there have been five mass extinctions in the last 600 million years, including the Cretaceous Extinction, during which an asteroid knocked out the dinosaurs. Though these events were initially destructive, they were also prime movers of evolutionary change in nature. And we can see some of the warning signs of another extinction event coming, as our oceans lose both fish and oxygen. In The Next Species, Michael Tennesen questions what life might be like after it happens.Tennesen discusses the future of nature and whether humans will make it through the bottleneck of extinction. Without man, could the seas regenerate to what they were before fishing vessels? Could life suddenly get very big as it did before the arrival of humans? And what if man survives the coming catastrophes, but in reduced populations? Would those groups be isolated enough to become distinct species? Could the conquest of Mars lead to another form of human? Could we upload our minds into a computer and live in a virtual reality? Or could genetic engineering create a more intelligent and long-lived creature that might shun the rest of us? And how would we recognize the next humans? Are they with us now?Tennesen delves into the history of the planet and travels to rainforests, canyons, craters, and caves all over the world to explore the potential winners and losers of the next era of evolution. His predictions, based on reports and interviews with top scientists, have vital implications for life on earth today.

    But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.

    Fuzzy brown molds mischievously turn forgotten peaches to slime in the kitchen fruit bowl. And in thousands of other ways, members of the kingdom Fungi do their part to make life on Earth the miracle that it is. In this lively book, George Hudler leads us on a tour of an often-overlooked group of organisms, which differ radically from both animals and plants. Along the way the author stops to ponder the marvels of nature and the impact of mere microbes on the evolution of civilization. Nature's ultimate recyclers not only save us from drowning in a sea of organic waste, but also provide us with food, drink, and a wide array of valuable medicines and industrial chemicals.Some fungi make deadly poisons and psychedelic drugs that have interesting histories in and of themselves, and Hudler weaves tales of those into his scientific account of the nature of the fungi. The role of fungi in the Irish potato famine, in the Salem Witch Trials, in the philosophical writings of Greek scholars, and in the creation of ginger snaps are just a few of the many great moments in history to grace these pages.Hudler moves so easily from discussing human history to exploring scientific knowledge, all with a sense of humor and enthusiasm, that one can well understand why he is an award-winning teacher both at Cornell University as well as nationally. Few, for instance, who read his invitation to get out of your chair and take a short walk will ever again look without curiosity and admiration at the rotten part of the world around them. Magical Mushrooms, Mischievous Molds is full of information that will satisfy history buffs, science enthusiasts, and anyone interested in nature's miracles. Everyone in Hudler's audience will develop a new appreciation of the debt they owe to the molds for such common products as penicillin, wine, and bread.

    They attracted followers ranging from Thomas Jefferson, who laid out mastodon bones on the White House floor, to twentieth-century doctors who used their knowledge of new species to conquer epidemic diseases. Acclaimed science writer Richard Conniff brings these daredevil "species seekers" to vivid life. Alongside their globe-spanning tales of adventure, he recounts some of the most dramatic shifts in the history of human thought. At the start, everyone accepted that the Earth had been created for our benefit. We weren't sure where vegetable ended and animal began, we couldn't classify species, and we didn't understand the causes of disease. But all that changed as the species seekers introduced us to the pantheon of life on Earth—and our place within it.

    The book is conveniently divided into three sections: Section one shows how language is used in multilingual speech communities and explains the varying patterns of language use. Janet Holmes examines how and why languages change within society and highlights the factors that lead to the displacement of one language by another and sometimes the death of a language. Section two explores social reasons for language change, looking at language change in monolingual communities and the features of a variety of dialects. The author shows how and why differing racial and social groups develop and maintain speech variations. The final section assesses how attitudes to language affect speech and shows that linguistic responses depend on a variety of contextual factors - for example, the status of the person being addressed and our re
