However, this is changing. Due to new technologies scientists are able to access the ancient biomolecules--the pigments, proteins, chemicals, andDNA--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 mayhave 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"-- $c Provided by publisher. 650 0 $a Biomolecules, Fossil. 650 0 $a DNA, Fossil $x Analysis. 650 7 $a NATURE / Fossils $2 bisacsh 650 7 $a SCIENCE / Earth Sciences / General $2 bisacsh 776 08 $i Online version: 776 08 $a Greenwalt, Dale E., 1949- $t Remnants of ancient life $d Princeton, New Jersey : Princeton University Press, [2022] $z 9780691221151 $w (DLC) 2022013106 941 $a 2 952 $l CAPH522 $d 20230307010642.0 952 $l BAPH771 $d 20230124010538.0 956 $a http://locator.silo.lib.ia.us/search.cgi?index_0=id&term_0=D965E1549BB411EDB33124244DECA4DBInitiate Another SILO Locator Search
