Book Synopsis The Evolution of Feathers by : Christian Foth
Download or read book The Evolution of Feathers written by Christian Foth and published by Springer Nature. This book was released on 2020-03-11 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feathers are one of the most unique characteristics of modern birds and represent the most complex and colourful type of skin derivate within vertebrates, while also fulfilling various biological roles, including flight, thermal insulation, display, and sensory function. For years it was generally assumed that the origin of flight was the main driving force for the evolution of feathers. However, various discoveries of dinosaur species with filamentous body coverings, made over the past 20 years, have fundamentally challenged this idea and produced new evolutionary scenarios for the origin of feathers. This book is devoted to the origin and evolution of feathers, and highlights the impact of palaeontology on this research field by reviewing a number of spectacular fossil discoveries that document the increasing morphological complexity along the evolutionary path to modern birds. Also featuring chapters on fossil feather colours, feather development and its genetic control, the book offers a timely and comprehensive overview of this popular research topic.

Book Synopsis Mechanisms and Evolution of Iridescent Feather Colors in Birds by : Chad M. Eliason
Download or read book Mechanisms and Evolution of Iridescent Feather Colors in Birds written by Chad M. Eliason and published by . This book was released on 2014 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A longstanding question in biology is why phenotypic diversity is unevenly distributed across the tree of life. Such differences can be caused by both extrinsic (e.g., natural selection) and intrinsic factors (e.g., how a trait functions). Despite numerous examples of diversification in form and function of complex biomechanical traits, we know relatively little about these processes in ornamental traits. Diverse ornamental feather colors in birds can be produced either by absorption (pigment-based colors) or scattering of light by feather nanostructures (structural colors). Because structural colors are deterministically related to the nanostructures that produce them, they are excellent systems to study form-function relationships and diversity of ornamental traits. In my dissertation I combine methods from physics and evolutionary biology to understand how proximate mechanisms explaining color (coherent light scattering) explain patterns of color diversity using iridescent feathers as a model system. Specifically, I ask two fundamental questions, one proximate and one ultimate, about iridescent colors: i) How are iridescent colors produced? and ii) What are the implications of how iridescent traits function for how they evolve? To tackle these questions, I sampled a nanostructurally diverse range of species, quantified their nanostructures with TEM and optical microscopy, experimentally tested the roles of different nanostructural traits in producing color by modifying them at the nanometer scale with FIB milling or humidity changes, and linked form and function with optical modeling. I then used simulation-based approaches and large-scale comparative analysis of color diversity to explore evolutionary consequences of functionally modular nanostructures in feathers. Together, my results suggest that morphological novelties in birds have, at least in part, allowed birds to achieve their vast morphological and colour diversity, and the way a color is produced has implications for how it evolves. The results of this research better our understanding of why bird colors are so diverse, generate testable hypotheses about the functions and evolution of bird colors, and demonstrate previously unforeseen costs of iridescent plumages that may help to explain the evolution and distribution of iridescence in birds.

Book Synopsis Homology, Genes, and Evolutionary Innovation by : Günter P. Wagner
Download or read book Homology, Genes, and Evolutionary Innovation written by Günter P. Wagner and published by Princeton University Press. This book was released on 2018-07-10 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major synthesis of homology, written by a top researcher in the field Homology—a similar trait shared by different species and derived from common ancestry, such as a seal's fin and a bird’s wing—is one of the most fundamental yet challenging concepts in evolutionary biology. This groundbreaking book provides the first mechanistically based theory of what homology is and how it arises in evolution. Günter Wagner, one of the preeminent researchers in the field, argues that homology, or character identity, can be explained through the historical continuity of character identity networks—that is, the gene regulatory networks that enable differential gene expression. He shows how character identity is independent of the form and function of the character itself because the same network can activate different effector genes and thus control the development of different shapes, sizes, and qualities of the character. Demonstrating how this theoretical model can provide a foundation for understanding the evolutionary origin of novel characters, Wagner applies it to the origin and evolution of specific systems, such as cell types; skin, hair, and feathers; limbs and digits; and flowers. The first major synthesis of homology to be published in decades, Homology, Genes, and Evolutionary Innovation reveals how a mechanistically based theory can serve as a unifying concept for any branch of science concerned with the structure and development of organisms, and how it can help explain major transitions in evolution and broad patterns of biological diversity.

Book Synopsis Cognition, Evolution, and Behavior by : Sara J. Shettleworth
Download or read book Cognition, Evolution, and Behavior written by Sara J. Shettleworth and published by Oxford University Press. This book was released on 2010-04-10 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do animals perceive the world, learn, remember, search for food or mates, communicate, and find their way around? Do any nonhuman animals count, imitate one another, use a language, or have a culture? What are the uses of cognition in nature and how might it have evolved? What is the current status of Darwin's claim that other species share the same "mental powers" as humans, but to different degrees? In this completely revised second edition of Cognition, Evolution, and Behavior, Sara Shettleworth addresses these questions, among others, by integrating findings from psychology, behavioral ecology, and ethology in a unique and wide-ranging synthesis of theory and research on animal cognition, in the broadest sense--from species-specific adaptations of vision in fish and associative learning in rats to discussions of theory of mind in chimpanzees, dogs, and ravens. She reviews the latest research on topics such as episodic memory, metacognition, and cooperation and other-regarding behavior in animals, as well as recent theories about what makes human cognition unique. In every part of this new edition, Shettleworth incorporates findings and theoretical approaches that have emerged since the first edition was published in 1998. The chapters are now organized into three sections: Fundamental Mechanisms (perception, learning, categorization, memory), Physical Cognition (space, time, number, physical causation), and Social Cognition (social knowledge, social learning, communication). Shettleworth has also added new chapters on evolution and the brain and on numerical cognition, and a new chapter on physical causation that integrates theories of instrumental behavior with discussions of foraging, planning, and tool using.
