In 1936 a German chemist identified certain organic molecules in ancient rocks and oils as the fossil remains of chlorophyll, presumably from plants that had lived millions of years in the past. Many years later this insight was revisited and the term biomarker coined to describe fossil molecules whose molecular structures could reveal the presence of otherwise elusive organisms and processesand then, the hunt was on. Echoes of Life is the story of those molecules and how they illuminate the history of the earth and its life. It is also the story of how a few maverick organic chemists and geologists defied the dictates of their disciplines and, at a time when the natural sciences were fragmenting into ever-more-specialised sub-disciplines, reunited chemistry, biology and geology in a common endeavor.

The revolution in science that is transforming our understanding of extinct lifeWe 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.

Ancient DNA Typing is a comprehensive manual about the analysis of ancient and degraded DNA. It is an equally useful textbook and working tool for various disciplines such as: Anthropology, Archaeology, Forensic Medicine, Conservation Biology, Environmental Sciences and Food Engineering. The reader benefits from a clear division of strategies, methods and applications with many interesting examples of the analysis of historic skeletal and cultural remains. The book contains a detailed protocol chapter which serves as a lab manual with the most important methods for DNA extraction, PCR and electrophoretic analysis of degraded samples. The appendix helps to set up a PCR lab specializing in ancient DNA research and answers the most frequent questions concerning technical problems in investigations of degraded DNA.
