"Inspired by the spectacular discoveries of the past two decades from the Age of Reptiles in China, Riddle of the Feathered Dragons explores how these miraculous fossils have transformed the contentious arena of bird and dinosaur evolution. Aside from being the most comprehensive discussion of these avian and associated discoveries, the author delves into the world of investigative journalism to expose the darker side of the world of fossil birds and dinosaurs. The book exposes the massive unfounded speculation that has characterized the field of vertebrate paleontology and published extensively in the world's most prestigious journals, including everything from supposed dinosaur protein to so-called feathered dinosaurs. The book questions the validity of the foundational tenets of the now "unquestionable orthodoxy" of bird and dinosaur evolution, including bird origins, feathered dinosaurs, flight origin from the ground-up and hot-blooded dinosaurs and their proteins. It exposes how speculation has gone far beyond the ability of the currently available evidence to yield answers. The author concludes that birds are best defined by a more traditional definition of the possession of feathers and avian flight architecture, that the so-called "feathered dinosaurs" are most likely derived avians, and that flight clearly originated from the trees-down, from ancestors that antedated the dinosaurs, rather than a direct linear descent"--

Birds and dinosaurs have dominated human interest for decades. In this well-supported revolutionary view of the field, critical questions are explored with credible evidence and biological thought. Are birds derived directly from advanced dinosaurs, or are they closely related dinosaur cousins? Did flight originate via the natural "gravity-assisted" trees-down model, or from the improbable “gravity-resisted” ground-up model? Were the earliest birds ground-predators or trunk-climbing gliders? Were dinosaurs hot-blooded with insulating protofeathers, or highly active, cold-blooded reptiles? These are among the questions addressed in this path-breaking book. Current consensus suggests that early birds were earth-bound and flight began on the ground. Reversing that logic, since birds are hot-blooded, by inference so too were dinosaurs, and extraordinarily complex feathers, flight brain and inner ear, evolved before flight in dinosaurs. The iconic early bird Archaeopteryx, despite innumerable flight and arboreal features, is now displayed as an earth-bound predator that could not fly. In reality, we have yet to provide satisfactory explanations for much of the biological origin and early evolution of birds. Among the questions addressed is whether truly feathered dinosaurs are in reality lost or "hidden birds?" The architectural complexity of feathers leads the author to the conclusion that if an animal has evolved extraordinarily complex, aerodynamically-designed feathers, an avian flight hand, flight membranes, and a flight brain, it's a bird. Birds and dinosaurs captivate and enchant the human imagination. These intriguing animals have dominated the field of paleontology and evolution for the past half century, engendering heated debate on avian ancestry, the origin of flight and feathers, and the biology of their fossils. Are birds living dinosaurs? In this series of entertainingly contentious and captivating essays evolutionary biologist Alan Feduccia writes with verve and humor to expose major problems in the field and advocate liberation from the shackles of consensus thinking about birds and dinosaurs. He maintains that the euphoria of paleontologists claiming to have solved the major problems of bird evolution is premature, largely generated by the adoption of a rigid, cult-like methodology, heavily blended with ideology, and excluding many biological and geological principles. He adroitly exposes and elucidates major mistakes in the field and their aftermath. Romancing the Birds and Dinosaurs is a lucid revelation of clarity and synthesis, a fascinating unveiling of the underlying science that has produced the good, but also often appalling fossil research and wild speculation in bird and dinosaur evolution. A must read for anyone interested in this rapidly evolving field, the short, concise and incisive essays provide the reader with access to this complex topic. REVIEWS and WORDS OF PRAISE In this strikingly unconventional and brilliant book, Professor Alan Feduccia presents the current status of the recent controversy about the origin of birds with clarity and vigor. A thought-provoking personal exploration of what the bird fossils represent. ---Sankar Chatterjee, Paul Whitfield Horn Distinguished Professor of Geosciences and Curator of Paleontology, Texas Tech University. Feduccia's book eloquently reminds us that consensus science is to be shied away from especially when it is used to plead special cases against basic scientific principles. The concept of “lost birds” is particularly intriguing as it defines what birds are and how special science obfuscates the simplicity of evolution. ---David A. Burnham, Associate Researcher, University of Kansas Biodiversity Institute and Natural History Museum. Based on a thorough understanding of the empirical evidence, Feduccia presents a convincing account of avian origins from their putative ancestors. ---Walter J. Bock, Professor of Evolutionary Biology, Columbia University and Research Associate, American Museum of Natural History. With candor, clear thinking, humor, and abundant evidence, Alan Feduccia’s Romancing the Birds and Dinosaurs should be mandatory reading for the countless millions who are intrigued by dinosaurs and their relatives, the birds. Feduccia points out the many empirical and logical shortcomings in the stubborn majority view that birds evolved from dinosaurs, an idea now solidly entrenched as dogma in education and popular culture. This new book will be as interesting to those who study human behavior and scientific methods as it will to students of vertebrate evolution. ---David W. Steadman, Curator of Ornithology, Professor of Biology, Florida Museum of Natural History, University of Florida.

Ten Thousand Birds provides a thoroughly engaging and authoritative history of modern ornithology, tracing how the study of birds has been shaped by a succession of visionary and often-controversial personalities, and by the unique social and scientific contexts in which these extraordinary individuals worked. This beautifully illustrated book opens in the middle of the nineteenth century when ornithology was a museum-based discipline focused almost exclusively on the anatomy, taxonomy, and classification of dead birds. It describes how in the early 1900s pioneering individuals such as Erwin Stresemann, Ernst Mayr, and Julian Huxley recognized the importance of studying live birds in the field, and how this shift thrust ornithology into the mainstream of the biological sciences. The book tells the stories of eccentrics like Colonel Richard Meinertzhagen, a pathological liar who stole specimens from museums and quite likely murdered his wife, and describes the breathtaking insights and discoveries of ambitious and influential figures such as David Lack, Niko Tinbergen, Robert MacArthur, and others who through their studies of birds transformed entire fields of biology. Ten Thousand Birds brings this history vividly to life through the work and achievements of those who advanced the field. Drawing on a wealth of archival material and in-depth interviews, this fascinating book reveals how research on birds has contributed more to our understanding of animal biology than the study of just about any other group of organisms.

A groundbreaking argument on how endothermy--arguably the most important innovation in vertebrate evolution--developed in birds and mammals "Vividly narrated and illustrated. . . . Provocative and fascinating for specialists and lay readers alike."--Southeastern Naturalist This pioneering work investigates why endothermy, or "warm-bloodedness," evolved in birds and mammals, despite its enormous energetic costs. Arguing that single-cause hypotheses to explain the origins of endothermy have stalled research since the 1970s, Barry Gordon Lovegrove advances a novel conceptual framework that considers multiple potential causes and integrates data from the southern as well as the northern hemisphere. Drawing on paleontological data; research on extant species in places like the Karoo, Namaqualand, Madagascar, and Borneo; and novel physiological models, Lovegrove builds a compelling new explanation for the evolution of endothermy. Vividly narrated and illustrated, this book stages a groundbreaking argument that should prove provocative and fascinating for specialists and lay readers alike.

The emphasis in this volume is on the structure and functional design of the integument. The book starts with a brief introduction to some basic principles of physics (mechanics) including Newton’s Three Laws of Motion. These principles are subsequently used to interpret the problems animals encounter in motion. It is in only the last 40 or so years that we have begun to understand how important a role the integument plays in the locomotion of many marine vertebrates. This involves the crossed-fiber architecture, which was first discovered in a classic study on nemertean worms. As a design principle we see that the crossed-fiber architecture is ubiquitous in nature. Research on some of the most dynamic marine vertebrates of the oceans – tuna, dolphins and sharks, and the extinct Jurassic ichthyosaurs – shows precisely how the crossed-fiber architecture contributes to high-speed swimming and (in lamnid sharks) may even aid in energy conservation. However, this design principle is not restricted to animals in the marine biota but is also found as far afield as the dinosaurs and, most recently, has been revealed as a major part of the microstructure of the most complex derivative of the integument, the feather. We see that a variety of phylogenetically diverse vertebrates take to the air by using skin flaps to glide from tree to tree or to the ground, and present detailed descriptions of innovations developed in pursuit of improved gliding capabilities in both extinct and modern day gliders. But the vertebrate integument had even greater things in store, namely true or flapping flight. Pterosaurs were the first vertebrates to use the integument as a membrane in true flapping flight and these interesting extinct animals are discussed on the basis of past and cutting-edge research , most intriguingly with respect to the structure of the flight membrane. Bats, the only mammals that fly, also employ integumental flight membranes. Classic research on bat flight is reviewed and supplemented with the latest research, which shows the complexities of the wing beat cycle to be significantly different from that of birds, as revealed by particle image velocimetry. The book’s largest chapter is devoted to birds, given that they make up nearly half of the over 22,000 species of tetrapods. The flight apparatus of birds is unique in nature and is described in great detail, with innovative research highlighting the complexity of the flight structures, bird flight patterns, and behavior in a variety of species. This is complimented by new research on the brains of birds, which shows that they are more complex than previously thought. The feather made bird flight possible, and was itself made possible by β-keratin, contributing to what may be a unique biomechanical microstructure in nature, a topic discussed in some depth. A highly polarized subject concerns the origin of birds and of the feather. Alleged fossilized protofeathers (primal simple feathers) are considered on the basis of histological and taphonomic investigative studies in Chapter 6. Finally, in Chapter 7 we discuss the controversies associated with this field of research. Professor Theagarten Lingham-Soliar works at the Nelson Mandela Metropolitan University, Port Elizabeth and is an Honorary Professor of Life Sciences at the University of KwaZulu-Natal.

In 1872, a young graduate of Yale University named Thomas Russell unearthed the bones of an 83,000,000-year-old dinosaur in western Kansas. The rare fossil, an avian dinosaur with teeth and flightless wings, proved that birds evolved from reptiles. More than a century later, Russell’s great-granddaughter set out to retrace her ancestor’s forgotten expedition. Part detective history, part memoir, For Want of Wings is Jill Hunting’s captivating account of her journey into prehistory, national history, and family history. In her quest to piece together fragments of her family’s past, Hunting ends up crisscrossing the United States, from California to Connecticut. On her first trip across the Colorado Rockies to the fossil bed site near Russell Springs, Kansas, Hunting brings along her then twenty-six-year-old daughter. When the book opens, mother and daughter are both at crossroads, each seeking to understand the impact of personal decisions on the landscape of her life. As Hunting ventures forward, she encounters unexpected resources, such as ten-year-old triplets who converse with her about dinosaurs and a Connecticut museum where portraits of her ancestors hang on the walls. Through lively descriptions of these visits, Hunting advances a view of history as nonlinear and full of unlikely coincidences. For Want of Wings is also the carefully researched story of the least known of Yale’s four expeditions into the American West, led by eminent paleontologist O. C. Marsh; the friendship between Russell’s father and abolitionist John Brown; a portrait of a mother and daughter evolving in self-understanding; and an inquiry into matters of race in American history and the author’s own family. In the end, all these pieces converge, like fragments of a fossil, to form an exquisitely patterned work of historical exploration.

What are religions? Why is it important to understand them? One answer is that religions and religious believers are extremely bad news: they are deeply involved in conflicts around the globe; they harm people of whom they disapprove; and they often seem irrational. Another answer claims that they are in fact extremely good news: religious beliefs and practices are universal and so fundamental in human nature that they have led us to great discoveries in our explorations of the cosmos and of who we are. The sciences began as part of that religious exploration. John Bowker demonstrates that there is truth in both answers and that we need both to understand what religion is and why it matters. He draws on many disciplines - from physics, genetics and the neurosciences to art, anthropology and the history of religions - to show how they shed entirely new light on religion in the modern world.
