Where do turtles hail from? Why and how did they acquire shells? These questions have spurred heated debate and intense research for more than two hundred years. Brilliantly weaving evidence from the latest paleontological discoveries with an accessible, incisive look at different theories of biological evolution and their proponents, Turtles as Hopeful Monsters tells the fascinating evolutionary story of the shelled reptiles. Paleontologist Olivier Rieppel traces the evolution of turtles from over 220 million years ago, examining closely the relationship of turtles to other reptiles and charting the development of the shell. Turtle issues fuel a debate between proponents of gradual evolutionary change and authors favoring change through bursts and leaps of macromutation. The first book-length popular history of its type, this indispensable resource is an engaging read for all those fascinated by this ubiquitous and uniquely shaped reptile.

Featuring in-depth contributions from an international team of experts, the Biology of Turtles provides the first comprehensive review of the Testudinata. The book starts with the premise that the structure of turtles is particularly interesting and best understood within the context of their development, novelty, functional diversity, and evolution. It provides a robust discussion of the development and diversity of the shell. The book also explores the turtle body plan, its physiological and ecological consequences, evolutionary novelties, and their importance. The 200 illustrations found throughout the text enhance the chapters combine with color illustrations of the development of the shell, aspects of bone structural diversity, growth, and skeletochronology, to make this book an unparalleled resource. The volume concludes with a thoughtful discussion of the more than century long debate on the origins of turtles and the reasons why our understanding of the phylogenic origins and evolution of turtles remains tentative. Currently available books on this subject are woefully out of date and no overall review of Testudinata has been undertaken...until now. Each chapter represents a milestone in synthesizing a wide range of available information on specific subjects. The book’s challenge: look both inside and outside the shell to build a clearer understanding of the diversity and evolution of turtles.

How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods evolve from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the 500-million-year history of vertebrate life. And with the aid of new techniques and approaches across a range of fields—work spanning multiple levels of biological organization from DNA sequences to organs and the physiology and ecology of whole organisms—we are now beginning to unravel the confounding evolutionary mysteries contained in the structure, genes, and fossil record of every living species. This book gathers a diverse team of renowned scientists to capture the excitement of these new discoveries in a collection that is both accessible to students and an important contribution to the future of its field. Marshaling a range of disciplines—from paleobiology to phylogenetics, developmental biology, ecology, and evolutionary biology—the contributors attack particular transformations in the head and neck, trunk, appendages such as fins and limbs, and the whole body, as well as offer synthetic perspectives. Illustrated throughout, Great Transformations in Vertebrate Evolution not only reveals the true origins of whales with legs, fish with elbows, wrists, and necks, and feathered dinosaurs, but also the relevance to our lives today of these extraordinary narratives of change.

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

Evolutionists have long known that Charles Darwin's original argument against his own theory - that a lack of fossil evidence of transitional forms would reduce him to an embarrassing footnote in history - was screamingly true. No legitimate fossil evidence exists that shows one species changing into another. This startling realization led Luther Sunderland to an exhaustive search of the subject, and his findings show clearly that evolution is a theory in disarray. From his own interviews with leading evolutionists, and an examination of the fossil evidence, Sunderland shows that the Enigma of Darwin's anti-God philosophy is that the facts show it is anything but rock-solid. Before is death in 1987, Luther Sunderland had garnered the respect of creationists worldwide for his investigative writing of the evolution controversy. After obtaining an engineering degree from Penn State University, Sunderland spent 30 years developing automatic flight control systems for the General Electric Company. DARWIN'S ENIGMA remains on intensely popular work on the theory of origins.
