Book Description
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.

Book Description
Scientists have recovered more than a billion fossils, but no discovery has been more breath-taking than the fossils recently found in northern China, findings which prove that several families of dinosaurs had feathers, or feathery hair-like coverings, adorning their bodies. Now in the beautifully designed Feathered Dinosaurs, paleontologist John Long and illustrator Peter Schouten provide a stunning visual record of these extraordinary prehistoric creatures, illuminating the evolutionary march from primitive, feathered dinosaurs through to the first true flying birds. Schouten, an acclaimed natural history artist, has created 80 full-color paintings that capture the striking physical traits of these feathered dinosaurs. Drawing on his extensive knowledge of the lifestyles of modern birds and mammals, plus the extant scientific data regarding how these dinosaurs might have looked and behaved, Schouten has produced not only the most beautiful but also the most accurate visual representations of these animals in print. Equally important, John Long, a noted paleontologist and widely published science author (with some 24 books to his credit), provides an engaging companion text that places these feathered dinosaurs within the larger family of dinosaurs--for instance, outlining their relationship to T. Rex and Velociraptor, species well known to Jurassic Park fans--and discusses the factual information that can be deduced from their fossil remains, in effect providing an insightful natural history of this remarkable group. A true marriage of art and science, Feathered Dinosaurs presents an unprecedented visual record of one of the most significant breakthroughs in the history of vertebrate paleontology--the discovery that many predatory dinosaurs were cloaked with feathers, perhaps just as colorful and fanciful as those of their living relatives.

The Ascent of Birds

The Ascent of Birds PDF Author: John Reilly
Publisher: Pelagic Publishing Ltd
ISBN: 1784271705
Category : Science
Languages : en
Pages : 369

Book Description
When and where did the ancestors of modern birds evolve? What enabled them to survive the meteoric impact that wiped out the dinosaurs? How did these early birds spread across the globe and give rise to the 10,600-plus species we recognise today ― from the largest ratites to the smallest hummingbirds? Based on the latest scientific discoveries and enriched by personal observations, The Ascent of Birds sets out to answer these fundamental questions. The Ascent of Birds is divided into self-contained chapters, or stories, that collectively encompass the evolution of modern birds from their origins in Gondwana, over 100 million years ago, to the present day. The stories are arranged in chronological order, from tinamous to tanagers, and describe the many dispersal and speciation events that underpin the world's 10,600-plus species. Although each chapter is spearheaded by a named bird and focuses on a specific evolutionary mechanism, the narrative will often explore the relevance of such events and processes to evolution in general. The book starts with The Tinamou’s Story, which explains the presence of flightless birds in South America, Africa, and Australasia, and dispels the cherished role of continental drift as an explanation for their biogeography. It also introduces the concept of neoteny, an evolutionary trick that enabled dinosaurs to become birds and humans to conquer the planet. The Vegavis's Story explores the evidence for a Cretaceous origin of modern birds and why they were able to survive the asteroid collision that saw the demise not only of dinosaurs but of up to three-quarters of all species. The Duck's Story switches to sex: why have so few species retained the ancestral copulatory organ? Or, put another way, why do most birds exhibit the paradoxical phenomenon of penis loss, despite all species requiring internal fertilisation? The Hoatzin's Story reveals unexpected oceanic rafting from Africa to South America: a stranger-than-fiction means of dispersal that is now thought to account for the presence of other South American vertebrates, including geckos and monkeys. The latest theories underpinning speciation are also explored. The Manakin’s Story, for example, reveals how South America’s extraordinarily rich avifauna has been shaped by past geological, oceanographic and climatic changes, while The Storm-Petrel’s Story examines how species can evolve from an ancestral population despite inhabiting the same geographical area. The thorny issue of what constitutes a species is discussed in The Albatross's Story, while The Penguin’s Story explores the effects of environment on phenotype ― in the case of the Emperor penguin, the harshest on the planet. Recent genomic advances have given scientists novel approaches to explore the distant past and have revealed many unexpected journeys, including the unique overland dispersal of an early suboscine from Asia to South America (The Sapayoa’s Story) and the blackbird's ancestral sweepstake dispersals across the Atlantic (The Thrush’s Story). Additional vignettes update more familiar concepts that encourage speciation: sexual selection (The Bird-of-Paradise's Story); extended phenotypes (The Bowerbird's Story); hybridisation (The Sparrow's Story); and 'great speciators' (The White-eye's Story). Finally, the book explores the raft of recent publications that help explain the evolution of cognitive skills (The Crow's Story); plumage colouration (The Starling's Story); and birdsong (The Finch's Story)

Dragon Songs

Dragon Songs PDF Author: Vladimir Dinets
Publisher: Arcade

Category : Nature
Languages : en
Pages : 0

Book Description
The amazing story of a groundbreaking scientific quest over five continents to study our modern dinosaurs—that ends up changing a life, as well as our understanding about crocodiles and their relatives. A born naturalist and a fearless traveler, Vladimir Dinets wrote travel guides, conducted field research, and lived a couple of lives before he was accepted into the PhD program in zoology at the University of Miami. He thought crocodiles were a dead-end research topic—survivors from the age of the dinosaurs but not much else—until he witnessed groups of up to seventy alligators performing mating choruses that included infrasound vibrations—a form of communication extremely rare in nature—and a “dance” unknown in the scientific literature but that resembled a scene from Jurassic Park. To prove his thesis about the language of crocodiles, he spent the next six years traveling around the world on shoestring budgets and in extreme circumstances, studying almost every living species. At the same time, as a man desiring companionship in life, he sought love. With adventures on five continents, Dragon Songs is his account of this quest. It includes an escape from a boiling lava lake in the Afar Desert, being chased up a tree by a tiger in India, hitching a ride with a cocaine smuggler in Bolivia, and diving with giant Greenland sharks—all in the name of studying crocodiles, among which he routinely paddled in his inflatable kayak. Of course, not everything went according to plan. But, in the end, his ground-breaking research helped change the field. And during the course of his adventures, he met and courted his future wife.

How Birds Evolve

How Birds Evolve PDF Author: Douglas J. Futuyma
Publisher: Princeton University Press
ISBN: 0691264635
Category : Nature
Languages : en
Pages : 320

Book Description
"Why are male birds often so brightly colored? Why do some birds lay more eggs than others? Will bird species adapt to climate change? In How Birds Evolve, Douglas Futuyma invites readers into the amazing world of bird evolution to answer these and other questions. Futuyma's goal in this book is not to offer a comprehensive evolutionary history of birds, but to explore how the processes of evolution produced the distinctive features and behaviors we observe in birds today as well as their impressive diversity. Using one or two birds per chapters as a lens into broader questions, Futuyma explores how a bird's evolutionary history helps us understand the diversity of species and the bird tree of life and how natural selection explains most of the characteristics of birds from how populations adapt to sexual selection and birds' amazing social behavior. Futuyma concludes by discussing the future of birds, particularly patterns of extinction and whether they can adapt to a changing climate. Ultimately, Futuyman wants readers to see that evolutionary biology helps us to better understand birds, and that the reverse is also true: studies of birds have informed almost every aspect of evolutionary biology, from Darwin to today"--

The Passenger Pigeon

The Passenger Pigeon PDF Author: Errol Fuller
Publisher: Princeton University Press
ISBN: 140085220X
Category : Nature
Languages : en
Pages : 182

Book Description
A haunting, beautifully illustrated memorial to this iconic extinct bird At the start of the nineteenth century, Passenger Pigeons were perhaps the most abundant birds on the planet, numbering literally in the billions. The flocks were so large and so dense that they blackened the skies, even blotting out the sun for days at a stretch. Yet by the end of the century, the most common bird in North America had vanished from the wild. In 1914, the last known representative of her species, Martha, died in a cage at the Cincinnati Zoo. This stunningly illustrated book tells the astonishing story of North America's Passenger Pigeon, a bird species that—like the Tyrannosaur, the Mammoth, and the Dodo—has become one of the great icons of extinction. Errol Fuller describes how these fast, agile, and handsomely plumaged birds were immortalized by the ornithologist and painter John James Audubon, and captured the imagination of writers such as James Fenimore Cooper, Henry David Thoreau, and Mark Twain. He shows how widespread deforestation, the demand for cheap and plentiful pigeon meat, and the indiscriminate killing of Passenger Pigeons for sport led to their catastrophic decline. Fuller provides an evocative memorial to a bird species that was once so important to the ecology of North America, and reminds us of just how fragile the natural world can be. Published in the centennial year of Martha’s death, The Passenger Pigeon features rare archival images as well as haunting photos of live birds.

Category : Science
Languages : en
Pages : 240

Book Description
A Hudson Booksellers Staff Pick for the Best Books of 2013 One of Publishers Weekly's Top Ten Spring Science Books A Bookshop Santa Cruz Staff Pick Dinosaurs, with their awe-inspiring size, terrifying claws and teeth, and otherworldly abilities, occupy a sacred place in our childhoods. They loom over museum halls, thunder through movies, and are a fundamental part of our collective imagination. In My Beloved Brontosaurus, the dinosaur fanatic Brian Switek enriches the childlike sense of wonder these amazing creatures instill in us. Investigating the latest discoveries in paleontology, he breathes new life into old bones. Switek reunites us with these mysterious creatures as he visits desolate excavation sites and hallowed museum vaults, exploring everything from the sex life of Apatosaurus and T. rex's feather-laden body to just why dinosaurs vanished. (And of course, on his journey, he celebrates the book's titular hero, "Brontosaurus"—who suffered a second extinction when we learned he never existed at all—as a symbol of scientific progress.) With infectious enthusiasm, Switek questions what we've long held to be true about these beasts, weaving in stories from his obsession with dinosaurs, which started when he was just knee-high to a Stegosaurus. Endearing, surprising, and essential to our understanding of our own evolution and our place on Earth, My Beloved Brontosaurus is a book that dinosaur fans and anyone interested in scientific progress will cherish for years to come.
