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.

Told in rich detail and with gorgeous color recreations, this is the story of marine life in the age before the dinosaurs. During the Middle Triassic Period (247–237 million years ago), the mountain of Monte San Giorgio in Switzerland was a tropical lagoon. Today, it is a UNESCO World Heritage Site because it boasts an astonishing fossil record of marine life from that time. Attracted to an incredibly diverse and well-preserved set of fossils, Swiss and Italian paleontologists have been excavating the mountain since 1850. Synthesizing and interpreting over a century of discoveries through a critical twenty-first century lens, paleontologist Olivier Rieppel tells for the first time the complete story of the fish and marine reptiles who made that long-ago lagoon their home. Through careful analysis and vividly rendered recreations, he offers memorable glimpses of not only what Thalattosaurs, Protorosaurs, Ichthyosaurs, Pachypleurosaurs, and other marine life looked like but how they moved and lived in the lagoon. An invaluable resource for specialists and accessible to all, this book is essential to all who are fascinated with ancient marine life.

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.

This book is a thought-provoking assessment of assumptions inhibiting progress in comparative biology. The volume is inspired by a list generated years earlier by Donn Rosen, one of the most influential, innovative and productive comparative biologists of the latter 20th century. His list has assumed almost legendary status among comparative evolutionary biologists. Surprisingly many of the obstructing assumptions implicated by Rosen remain relevant today. Any comparative biologist hoping to avoid such assumptions in their own research will benefit from this introspective volume.

This volume celebrates the contributions of Dr. Eugene Gaffney to the study of turtles, through a diverse and complementary collection of papers that showcases the latest research on one of the most intriguing groups of reptiles. A mix of focused and review papers deals with numerous aspects of the evolutionary history of turtles, including embryonic development, origins, early diversification, phylogenetic relationships, and biogeography. Moreover it includes reports on important but poorly understood fossil turtle assemblages, provides historical perspectives on turtle research, and documents disease and variation in turtles. With its broad scope, which includes descriptions of material and new taxa from Australia, Asia, and Europe, as well as North and South America, this work will be an essential resource for anyone interested in the morphology and evolution of turtles. “This volume’s breadth of time, geography, and taxonomic coverage makes it a major contribution to the field and a ‘must have’ for all vertebrate paleontologists.”, James F. Parham, California State University, CA, USA “A comprehensive and sweeping overview of turtle evolution by the top experts in the field that will interest everyone curious about these unique reptiles.” Jason S. Anderson, University of Calgary, Canada “An invaluable addition to the literature that covers the full spectrum of approaches toward understanding the evolution of these noble creatures.” Ann C. Burke, Wesleyan University, CT , USA “A truly comprehensive volume that both the student of fossil turtles, as well as the general reader interested in these enigmatic creatures, will find fascinating.” Tyler Lyson, Yale University, CT, USA​

This book proposes a new way to think about evolution. The author carefully brings together evidence from diverse fields of science. In the process, he bridges the gaps between many different--and usually seen as conflicting--ideas to present one integrative theory named ONCE, which stands for Organic Nonoptimal Constrained Evolution. The author argues that evolution is mainly driven by the behavioral choices and persistence of organisms themselves, in a process in which Darwinian natural selection is mainly a secondary--but still crucial--evolutionary player. Within ONCE, evolution is therefore generally made of mistakes and mismatches and trial-and-error situations, and is not a process where organisms engage in an incessant, suffocating struggle in which they can't thrive if they are not optimally adapted to their habitats and the external environment. Therefore, this unifying view incorporates a more comprehensive view of the diversity and complexity of life by stressing that organisms are not merely passive evolutionary players under the rule of external factors. This insightful and well-reasoned argument is based on numerous fascinating case studies from a wide range of organisms, including bacteria, plants, insects and diverse examples from the evolution of our own species. The book has an appeal to researchers, students, teachers, and those with an interest in the history and philosophy of science, as well as to the broader public, as it brings life back into biology by emphasizing that organisms, including humans, are the key active players in evolution and thus in the future of life on this wonderful planet.

The story of an ancient sea turtle and what its survival says about our future, from the award-winning writer and naturalist Though nature is indifferent to the struggles of her creatures, the human effect on them is often premeditated. The distressing decline of sea turtles in Pacific waters and their surprising recovery in the Atlantic illuminate what can go both wrong and right from our interventions, and teach us the lessons that can be applied to restore health to the world's oceans and its creatures. As Voyage of the Turtle, Carl Safina's compelling natural history adventure makes clear, the fate of the astonishing leatherback turtle, whose ancestry can be traced back 125 million years, is in our hands. Writing with verve and color, Safina describes how he and his colleagues track giant pelagic turtles across the world's oceans and onto remote beaches of every continent. As scientists apply lessons learned in the Atlantic and Caribbean to other endangered seas, Safina follows leatherback migrations, including a thrilling journey from Monterey, California, to nesting grounds on the most remote beaches of Papua, New Guinea. The only surviving species of its genus, family, and suborder, the leatherback is an evolutionary marvel: a "reptile" that behaves like a warm-blooded dinosaur, an ocean animal able to withstand colder water than most fishes and dive deeper than any whale. In his peerless prose, Safina captures the delicate interaction between these gentle giants and the humans who are finally playing a significant role in their survival. "Magnificent . . . A joyful, hopeful book. Safina gives us ample reasons to be enthralled by this astonishing ancient animal—and ample reasons to care." -- The Los Angeles Times

During the last decade, modern technologies have made a revolutionary change in developmental biology. The molecular and cellular processes in live embryos can now be visualized thanks to technologies using fluorescent proteins. The whole genome information of a wide range of animal species has now become available, confirming the common principles that operate in every species. These and other advances in our understanding of the developmental processes during embryogenesis and tissue regeneration have put forward new principles. Those new principles will also be important in the stem cell biology, branched from developmental biology, in order to generate a particular tissue by manipulating stem cells. This book is planned to introduce these new principles to readers who are working in developmental biology and/or stem cell biology fields, with an emphasis on genetic and cellular processes.
