Available in PDF, EPUB and Kindle. Book excerpt: "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"--

Book Synopsis On the Origin of Species Through Heteropatric Differentiation by : Kevin Winker
Download or read book On the Origin of Species Through Heteropatric Differentiation written by Kevin Winker and published by Univ of California Press. This book was released on 2010-11 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differentiation and speciation without extended isolation appear to be common among migratory animals. Historical oversight of this is probably due to temporal distortion in distribution maps and a tendency to consider that lineages had different historical traits, such as being sedentary or much less mobile. Mobility among cyclic migrants makes population isolation difficult, and diminished levels of intraspecific differentiation occur in avian migrants (I term this "Montgomery's rule"). Nevertheless, many lineages have differentiated despite increased mobility and a high propensity for gene flow, conditions that speciation theory has not addressed adequately. Populations of seasonal migrants usually occur in allopatry and sympatry during a migratory cycle, and this distributional pattern (heteropatry) is the focus of a model empirically developed to explain differentiation in migratory lineages. Divergence arises through disruptive selection from resource competition and heterogeneously distributed cyclic resources. Heteropatric speciation is a type of ecological speciation in which reproductive isolation increases between populations as a byproduct of adaptation to different environments that enhances breeding allopatry and allochrony despite degrees of sympatry that occur during the nonbreeding period in migration cycles. Mating or pair bonding in nonbreeding areas is rare. Patterns such as leapfrog migration and limited morphological divergence suggest that differentiation is driven by these ecological factors rather than by sexual selection or nontemporal changes in the resource base itself, although the additional presence of either of the latter would have additive divergent effects. Migratory lineages provide a largely neglected series of natural experiments in speciation in which to test predictions stemming from this model and others focusing on ecological speciation --

Book Synopsis Living Dinosaurs by : Dr. Gareth Dyke
Download or read book Living Dinosaurs written by Dr. Gareth Dyke and published by John Wiley & Sons. This book was released on 2011-02-15 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living Dinosaurs offers a snapshot of our current understanding of the origin and evolution of birds. After slumbering for more than a century, avian palaeontology has been awakened by startling new discoveries on almost every continent. Controversies about whether dinosaurs had real feathers or whether birds were related to dinosaurs have been swept away and replaced by new and more difficult questions: How old is the avian lineage? How did birds learn to fly? Which birds survived the great extinction that ended the Mesozoic Era and how did the avian genome evolve? Answers to these questions may help us understand how the different kinds of living birds are related to one another and how they evolved into their current niches. More importantly, they may help us understand what we need to do to help them survive the dramatic impacts of human activity on the planet.

Book Synopsis Exuberant Life by : William H. Durham
Download or read book Exuberant Life written by William H. Durham and published by Oxford University Press. This book was released on 2021 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The terrestrial organisms of the Galápagos Islands live under conditions unlike those anywhere else. At the edge of a uniquely rich mid-ocean upwelling, their world is also free of mammalian predators and competitors, allowing them to live unbothered, exuberant lives. With its giant tortoises, marine iguanas, flightless cormorants, and forests of giant daisies, there's no question that this is a magnificent place. Long before people traversed the Earth, evolution endowed native species with adaptations to these special conditions and to perturbations like El Niño events and periodic droughts. As the islands have grown ever-more connected with humanity, those same adaptations now make its species vulnerable. Today, the islands are best viewed as one big social-ecological system where the ability of each native organism to survive and reproduce is a product of human activity in addition to ecological circumstances. In this book, William H. Durham takes readers on a tour of Galápagos and the organisms that inhabit these isolated volcanic islands. Exuberant Life offers a contemporary synthesis of what we know about the evolution of its curiously wonderful organisms, how they are faring in the tumultuous changing world around them, and how evolution can guide our efforts today for their conservation. The book highlights the ancestry of a dozen specific organisms in these islands, when and how they made it to the Galápagos, as well as how they have changed in the meantime. Durham traces the strengths and weaknesses of each species, arguing that the mismatch between natural challenges of their habitats and the challenges humans have recently added is the main task facing conservation efforts today. Such analysis often provides surprises and suggestions not yet considered, like the potential benefits to joint conservation efforts between tree finches and tree daisies, or ways in which the peculiar evolved behaviors of Nazca and blue-footed boobies can be used to benefit both species today. In each chapter, a social-ecological systems framework is used to highlight links between human impact, including climate change, and species status today, Historically, the Galápagos have played a central role in our understanding of evolution; what these islands now offer to teach us about conservation may well prove indispensable for the future of the planet.
Book Synopsis Lost Land of the Dodo by : Anthony Cheke
Download or read book Lost Land of the Dodo written by Anthony Cheke and published by A&C Black. This book was released on 2009-01-01 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mascarene islands in the southern Indian Ocean - Mauritius, Réunion and Rodrigues - were once home to an extraordinary range of birds and reptiles. Evolving on these isolated volcanic islands in the absence of mammalian predators or competitors, the land was dominated by giant tortoises, parrots, skinks and geckos, burrowing boas, flightless rails & herons, and of course (in Mauritius) the Dodo. Uninhabited and only discovered in the 1500s, colonisation by European settlers in the 1600s led to dramatic changes in the ecology of the islands; the birds and tortoises were slaughtered indiscriminately while introduced rats, cats, pigs and monkeys destroyed their eggs, the once-extensive forests logged, and invasive introduced plants from all over the tropics devastated the ecosystem. The now-familiar icon of extinction, the Dodo, was gone from Mauritius within 50 years of human settlement, and over the next 150 years many of the Mascarenes' other native vertebrates followed suit. The product of over 30 years research by Anthony Cheke, Lost Land of the Dodo provides a comprehensive yet hugely enjoyable account of the story of the islands' changing ecology, interspersed with human stories, the islands' biogeographical anomalies, and much else. Many French publications, old and new, especially for Réunion, are discussed and referenced in English for the first time. The book is richly illustrated with maps and contemporary illustrations of the animals and their environment, many of which have rarely been reprinted before. Illustrated box texts look in detail at each extinct vertebrate species, while Julian Hume's superb colour plates bring many of the extinct birds to life. Lost Land of the Dodo provides the definitive account of this tragic yet remarkable fauna, and is a must-read for anyone interested in islands, their ecology and the history of our relationship with the world around us.

Book Synopsis Avian Molecular Evolution and Systematics by : David P. Mindell
Download or read book Avian Molecular Evolution and Systematics written by David P. Mindell and published by Academic Press. This book was released on 1997-05-13 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of DNA and other biological macromolecules has revolutionized systematic studies of evolutionary history. Methods that use sequences of nucleotides and amino acids are now routinely used as data for addressing evolutionary questions that, although not new questions, have defied description and analysis. The world-renowned contributors use these new methods to unravel particular aspects of the evolutionary history of birds. Avian Molecular Evolution and Systematics presents an overview of the theory and application of molecular systematics, focusing on the phylogeny and evolutionary biology of birds. New, developing areas in the phylogeny of birds at multiple taxonomic areas are covered, as well as methods of analysis for molecular data, evolutionary genetics within and between bird populations, and the application of molecular-based phylogenies to broader questions of evolution. Contains authoritative contributions from leading researchers Discusses the utility of different molecular markers for questions of avian evolution, involving populations and higher-level taxa Applies molecular-based phylogenies of birds and molecular population genetics data to broad questions of organismal and molecular evolution. Compares and contrasts molecular and morphological data sets
