Book Description
To help us understand what happened during the Ice Age, Peter Ward takes us on a tour of other mass extinctions through earth's history. He presents a compelling account of the great comet crash that killed off the dinosaurs, and describes other extinctions that were even more extensive. In so doing, he introduces us to a profound paradigm shift now taking place in paleontology: rather than arising from the gradual workings of everyday forces, all mass extinctions are due to unique, catastrophic events. Written with an irresistible combination of passion and expertise, The Call of Distant Mammoths is an engaging exploration of the history of life and the importance of humanity as an evolutionary force. "Carefully argued...an intelligent and compelling book."-THE OLYMPIAN, SEATTLE, WASHINGTON "Ward deftly summarizes a large body of scientific literature, simplifying complex ideas for the general reader without condescension."-PUBLISHERS WEEKLY "Did the overkill really happen?...Peter Ward deftly summarizes the arguments...Ward tells (the story) well."-THE NEW SCIENTIST

Book Description
The carefully crafted, meditative essays in On the Shoreline of Knowledge sometimes start from unlikely objects or thoughts, a pencil or some fragments of commonplace conversation, but they soon lead the reader to consider fundamental themes in human experience. The unexpected circumnavigation of the ordinary unerringly gets to the heart of the matter. Bringing a diverse range of material into play, from fifteenth-century Japanese Zen Buddhism to how we look at paintings, and from the nature of a briefcase to the ancient nest-sites of gyrfalcons, Chris Arthur reveals the extraordinary dimensions woven invisibly into the ordinary things around us. Compared to Loren Eiseley, George Eliot, Seamus Heaney, Aldo Leopold, V. S. Naipaul, W. G. Sebald, W. B. Yeats, and other literary luminaries, he is a master essayist whose work has quietly been gathering an impressive cargo of critical acclaim. Arthur speaks with an Irish accent, rooting the book in his own unique vision of the world, but he addresses elemental issues of life and death, love and loss, that circle the world and entwine us all.

Book Description
Limulus in the Limelight: A Species 350 Million Years in the Making and in Peril? contains 14 chapters covering the horseshoe crab's biology, ecology and evolutionary development. The book is a result of three mini-conferences held between 1996 and 2000 celebrating the populations in NY harbor. This book exposes the impacts of over fishing on this species; clarifies the future research agenda for the species worldwide and emphasizes the need for conservation of this fascinating creature's estuaries/ocean habitats. Biologists, ecologists, science educators, and conservationists will welcome this book because it is aimed at the preservation of Limulus, not only for its pharmacological interest but for the mystery related to its longevity. Limulus is a unique animal which has provided numerous uses for man over the years, from fertilizer to bait to medical research. However, if this species is not protected soon, it will be lost for the future.

Book Description
Paleontology is one of the most visible yet most misunderstood fields of science. Children dream of becoming paleontologists when they grow up. Museum visitors flock to exhibits on dinosaurs and other prehistoric animals. The media reports on fossil discoveries and new clues to mass extinctions. Nonetheless, misconceptions abound: paleontologists are assumed only to be interested in dinosaurs, and they are all too often imagined as bearded white men in battered cowboy hats. Roy Plotnick provides a behind-the-scenes look at paleontology as it exists today in all its complexity. He explores the field’s aims, methods, and possibilities, with an emphasis on the compelling personal stories of the scientists who have made it a career. Paleontologists study the entire history of life on Earth; they do not only use hammers and chisels to unearth fossils but are just as likely to work with cutting-edge computing technology. Plotnick presents the big questions about life’s history that drive paleontological research and shows why knowledge of Earth’s past is essential to understanding present-day environmental crises. He introduces readers to the diverse group of people of all genders, races, and international backgrounds who make up the twenty-first-century paleontology community, foregrounding their perspectives and firsthand narratives. He also frankly discusses the many challenges that face the profession, with key takeaways for aspiring scientists. Candid and comprehensive, Explorers of Deep Time is essential reading for anyone curious about the everyday work of real-life paleontologists.

Book Description
Voted one of Christianity Today's 1997 Books of the Year! Creation versus evolution. The debate is growing louder and hotter--whether in lecture halls or in between the pages of bestselling books. But neither side seems to be winning. Why? In The Battle of Beginnings Del Ratzsch examines the history of the debate and critiques the entrenched positions that he argues merely impede progress toward the truth. Dissatisfied with both creationist fallacies and materialist misconstruals, he seeks to lay the groundwork for more fruitful dialogue. In considerable detail Ratzsch looks at the history and development of Darwin's theory and common creationist misunderstandings of evolution. He then moves on to examine the history and development of creationist theory and pervasive evolutionist misunderstandings of it. He also discusses the nature of science and common creationist and evolutionist abuses as a prelude to showing why both sides have remained critical of theistic evolution. Above all, Ratzsch argues that until philosophical confusion, logical missteps and various other snarls have been untangled, little real progress can be made in sorting out competing theories of life and its origin. With this book he challenges and equips all of us to think more clearly.
