Remnants of Ancient Life


Book Description

The revolution in science that is transforming our understanding of extinct life We used to think of fossils as being composed of nothing but rock and minerals, all molecular traces of life having vanished long ago. We were wrong. Remnants of Ancient Life reveals how the new science of ancient biomolecules—pigments, proteins, and DNA that once functioned in living organisms tens of millions of years ago—is opening a new window onto the evolution of life on Earth. Paleobiologists are now uncovering these ancient remnants in the fossil record with increasing frequency, shedding vital new light on long-extinct creatures and the lost world they inhabited. Dale Greenwalt is your guide to these astonishing breakthroughs. He explains how ancient biomolecules hold the secrets to how mammoths dealt with the bitter cold, what colors dinosaurs exhibited in mating displays, how ancient viruses evolved to become more dangerous, and much more. Each chapter discusses different types of biomolecules and the insights they provide about the physiology, behavior, and evolution of extinct organisms, many of which existed long before the age of dinosaurs. A marvelous adventure of discovery, Remnants of Ancient Life offers an unparalleled look at an emerging science that is transforming our picture of the remote past. You will never think of fossils in the same way again.




Remnants of Ancient Life


Book Description

"We usually think of fossils as being composed of rock, the original contents of the organisms lost to time. However, this is changing. Due to new technologies scientists are able to access the ancient biomolecules--the pigments, proteins, chemicals, and DNA--that once performed critical roles in organisms and have been preserved accross millions of years. In this book, Dale Greenwalt introduces readers to the new science of ancient biomolecules and what it tells about the lives of long extinct life. Ancient biomolecules, as we learn, give us a whole new view into the past. After an introductory explanation of what biomolecules are (and are not), each chapter treats an ancient biomolecule and what it can teach us about a long-dead organism and how it may have lived. For example, analysis of preserved pigmentation has improved our understanding of the evolution of camouflage, feathered dinosaurs, and flight. Ancient proteins aid taxonomic identification and determinations of sex. And ancient DNA-perhaps the best-known ancient biomolecule-can shed light on species' ancestry, including our own. Drawing on a wealth of paleontological research, including his own, Greenwalt traces ancient organic material back millions of years. Throughout, he emphasizes the infancy of this science while the book's conclusion looks ahead to its possible future in everything from the search for life on other planets to de-extinction"--




A History of Life in 100 Fossils


Book Description

A History of Life in 100 Fossils showcases 100 key fossils that together illustrate the evolution of life on earth. Iconic specimens have been selected from the renowned collections of the two premier natural history museums in the world, the Smithsonian Institution, Washington, and the Natural History Museum, London. The fossils ahve been chosen not only for their importance in the history of life, but also because of the visual story they tell. This stunning book is perfect for all readers because its clear explanations and beautiful photographs illuminate the significance of these amazing pieces, including 500 million-year-old Burgess Shale fossils that provide a window into early animal life in the sea, insects encapsulated by amber, the first fossil bird Archaeopteryx, and the remains of our own ancestors.




Vital Remnants


Book Description

"America's founding generation was learned in the history and literature of the West and steeped in the English tradition of liberty. Vital Remnants revisits for a new generation the sources of America's greatness and suggests means to restore our weakened foundations."--BOOK JACKET.

The Remnants of War


Book Description

"War... is merely an idea, an institution, like dueling or slavery, that has been grafted onto human existence. It is not a trick of fate, a thunderbolt from hell, a natural calamity, or a desperate plot contrivance dreamed up by some sadistic puppeteer on high. And it seems to me that the institution is in pronounced decline, abandoned as attitudes toward it have changed, roughly following the pattern by which the ancient and formidable institution of slavery became discredited and then mostly obsolete."—from the Introduction War is one of the great themes of human history and now, John Mueller believes, it is clearly declining. Developed nations have generally abandoned it as a way for conducting their relations with other countries, and most current warfare (though not all) is opportunistic predation waged by packs—often remarkably small ones—of criminals and bullies. Thus, argues Mueller, war has been substantially reduced to its remnants—or dregs—and thugs are the residual combatants. Mueller is sensitive to the policy implications of this view. When developed states commit disciplined troops to peacekeeping, the result is usually a rapid cessation of murderous disorder. The Remnants of War thus reinvigorates our sense of the moral responsibility bound up in peacekeeping. In Mueller's view, capable domestic policing and military forces can also be effective in reestablishing civic order, and the building of competent governments is key to eliminating most of what remains of warfare.




Ancient and Fossil Bone Collagen Remnants


Book Description

"Do creation scientists do actual science, or do they just propagate religious talking points? Ancient and Fossil Bone Collagen Remnants, based on Dr. Brian Thomas’ PhD dissertation, answers this question. Intended for the technical science reader, it reveals results from research projects designed to address questions about the presence or absence, geographic and stratigraphic extent, and decay rate of collagen in ancient bones. Not only do the experiments and descriptions found in this volume show that yes, creation scientists do real science, but they also provide the solid technical background needed to address the question of why short-lived collagen has been found in supposedly very old dinosaur bones"--Publisher's description.




The Book of Naturalists


Book Description

This anthology covers animals, nature, and the history of biology. Reflecting his infectious enthusiasm for "the best natural history," the editor has excerpts from massive sources and intriguing pieces from lesser known authors. Among the naturalists included are Pliny, Frederick II, Linnaeus, White, Bartram, Waterton, Thoreau, Wallace, Huxley, Faber, Theodore Roosevelt, Digby, Seton, and Klingel. Arranged in chronological order, the small masterpieces here range from Aristotle to Rachel Carson. Each excerpt is introduced by an incisive and sometimes humorous description of its author.
