“Addresses an important topic for biologists and zoologists about vertebrates’ place in the ‘grand scheme’ . . . genuinely witty and charming . . . magnificent.” —Neil J. Gostling, University of Southampton Our understanding of vertebrate origins and the backbone of human history evolves with each new fossil find and DNA map. Many species have now had their genomes sequenced, and molecular techniques allow genetic inspection of even non-model organisms. But as longtime Nature editor Henry Gee argues in Across the Bridge, despite these giant strides and our deepening understanding of how vertebrates fit into the tree of life, the morphological chasm between vertebrates and invertebrates remains vast and enigmatic. As Gee shows, even as scientific advances have falsified a variety of theories linking these groups, the extant relatives of vertebrates are too few for effective genetic analysis. Moreover, the more we learn about the species that do remain—from sea-squirts to starfish—the clearer it becomes that they are too far evolved along their own courses to be of much use in reconstructing what the latest invertebrate ancestors of vertebrates looked like. Fossils present yet further problems of interpretation. Tracing both the fast-changing science that has helped illuminate the intricacies of vertebrate evolution as well as the limits of that science, Across the Bridge helps us to see how far the field has come in crossing the invertebrate-to-vertebrate divide—and how far we still have to go. “A beautiful ode to some of the least appreciated animals . . . guides the reader joyfully through deuterostomes—weaving disparate elements of embryology, paleontology, and morphology into an unprecedented and accessible narrative.” —Jakob Vinther, University of Bristol

Animals Without Backbones has been considered a classic among biology textbooks since it was first published to great acclaim in 1938. It was the first biology textbook ever reviewed by Time and was also featured with illustrations in Life. Harvard, Stanford, the University of Chicago, and more than eighty other colleges and universities adopted it for use in courses. Since then, its clear explanations and ample illustrations have continued to introduce hundreds of thousands of students and general readers around the world to jellyfishes, corals, flatworms, squids, starfishes, spiders, grasshoppers, and the other invertebrates that make up ninety-seven percent of the animal kingdom. This new edition has been completely rewritten and redesigned, but it retains the same clarity and careful scholarship that have earned this book its continuing readership for half a century. It is even more lavishly illustrated than earlier editions, incorporating many new drawings and photographs. Informative, concise legends that form an integral part of the text accompany the illustrations. The text has been updated to include findings from recent research. Eschewing pure morphology, the authors use each group of animals to introduce one or more biological principles. In recent decades, courses and texts on invertebrate zoology at many universities have been available only for advanced biology majors specializing in this area. The Third Edition of Animals Without Backbones remains an ideal introduction to invertebrates for lower-level biology majors, nonmajors, students in paleontology and other related fields, junior college and advanced high school students, and the general reader who pursues the rewarding study of the natural world.

The most up-to-date book on invertebrates, providing a new framework for understanding their place in the tree of life In The Invertebrate Tree of Life, Gonzalo Giribet and Gregory Edgecombe, leading authorities on invertebrate biology and paleontology, utilize phylogenetics to trace the evolution of animals from their origins in the Proterozoic to today. Phylogenetic relationships between and within the major animal groups are based on the latest molecular analyses, which are increasingly genomic in scale and draw on the soundest methods of tree reconstruction. Giribet and Edgecombe evaluate the evolution of animal organ systems, exploring how current debates about phylogenetic relationships affect the ways in which aspects of invertebrate nervous systems, reproductive biology, and other key features are inferred to have developed. The authors review the systematics, natural history, anatomy, development, and fossil records of all major animal groups, employing seminal historical works and cutting-edge research in evolutionary developmental biology, genomics, and advanced imaging techniques. Overall, they provide a synthetic treatment of all animal phyla and discuss their relationships via an integrative approach to invertebrate systematics, anatomy, paleontology, and genomics. With numerous detailed illustrations and phylogenetic trees, The Invertebrate Tree of Life is a must-have reference for biologists and anyone interested in invertebrates, and will be an ideal text for courses in invertebrate biology. A must-have and up-to-date book on invertebrate biology Ideal as both a textbook and reference Suitable for courses in invertebrate biology Richly illustrated with black-and-white and color images and abundant tree diagrams Written by authorities on invertebrate evolution and phylogeny Factors in the latest understanding of animal genomics and original fossil material

Animals In Saxon Scandinavian England written by Matilda Holmes and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2014 with Animal remains (Archaeology) categories.
In this book an analysis of over 300 animal bone assemblages from English Saxon and Scandinavian sites is presented. The data set is summarised in extensive tables for use as comparanda for future archaeozoological studies. Animals in Saxon and Scandinavian England takes as its core four broad areas of analysis. The first is an investigation of the diet of the population, and how food was used to establish social boundaries. Increasingly diverse diets are recognised, with high-status populations distinguishing themselves from other social sectors through the way food was redistributed and the diversity of taxa consumed. Secondly, the role of animals in the economy is considered, looking at how animal husbandry feeds into underlying modes of production throughout the Saxon period. From the largely self-sufficient early Saxon phase animal husbandry becomes more specialised to supply increasingly urban settlements. The ensuing third deliberation takes into account the foodways and interactions between producer and consumer sites, considering the distribution of food and raw materials between farm, table and craft worker. Fundamental changes in the nature of the Saxon economy distinguish a move away from food renders in the middle Saxon phase to market-based provisioning; opening the way for greater autonomy of supply and demand. Finally, the role of wics and burhs as centres of production is investigated, particularly the organisation of manufacture and provisioning with raw materials.
