Description of  Remnants of Ancient Life: The New Science of Old Fossils

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 biomoleculespigments, proteins, and DNA that once functioned in living organisms tens of millions of years agois 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, Read more
