Chordate Origins and Evolution by Noriyuki Satoh Pdf

Chordate Origins and Evolution: The Molecular Evolutionary Road to Vertebrates focuses on echinoderms (starfish, sea urchins, and others), hemichordates (acorn worms, etc.), cephalochordates (lancelets), urochordates or tunicates (ascidians, larvaceans and others), and vertebrates. In general, evolution of these groups is discussed independently, on a larger scale: ambulacrarians (echi+hemi) and chordates (cephlo+uro+vert). Until now, discussion of these topics has been somewhat fragmented, and this work provides a unified presentation of the essential information. In the more than 150 years since Charles Darwin proposed the concept of the origin of species by means of natural selection, which has profoundly affected all fields of biology and medicine, the evolution of animals (metazoans) has been studied, discussed, and debated extensively. Following many decades of classical comparative morphology and embryology, the 1980s marked a turning point in studies of animal evolution, when molecular biological approaches, including molecular phylogeny (MP), molecular evolutionary developmental biology (evo-devo), and comparative genomics (CG), began to be employed. There are at least five key events in metazoan evolution, which include the origins of 1) diploblastic animals, such as cnidarians; 2) triploblastic animals or bilaterians; 3) protostomes and deuterostomes; 4) chordates, among deuterostomes; and 5) vertebrates, among chordates. The last two have received special attention in relation to evolution of human beings. During the past two decades, great advances have been made in this field, especially in regard to molecular and developmental mechanisms involved in the evolution of chordates. For example, the interpretation of phylogenetic relationships among deuterostomes has drastically changed. In addition, we have now obtained a large quantity of MP, evo-devo, and CG information on the origin and evolution of chordates. Covers the most significant advances in this field to give readers an understanding of the interesting biological issues involved Provides a unified presentation of essential information regarding each phylum and an integrative understanding of molecular mechanisms involved in the origin and evolution of chordates Discusses the evolutionary scenario of chordates based on two major characteristic features of animals—namely modes of feeding (energy sources) and reproduction—as the two main forces driving animal evolution and benefiting dialogue for future studies of animal evolution

Across the Bridge by Henry Gee Pdf

“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

Advanced Chordate Zoology by Aubrey Salazar Pdf

The origin and evolution of chordates is one of the most mysterious and interesting phenomena in evolutionary development science. Chordates are creatures characterized by possession of a notochord and pharyngeal gill openings. They comprise of three taxa: cephalochordates, urochordates (or tunicates), and vertebrates. Chordates belong to a supraphyletic gathering of deuterostomes, together with echinoderms and hemichordates, and are thought to have been derived from the regular ancestors of deuterostomes. Vertebrates evoloved by developing a body design with the greatest complexity among metazoans. Amid the 1980s, a new wave of molecular developmental science revealed that genes encoding interpretation factors and flag pathway molecules assume critical roles in the differentiation of embryonic cells, arrangement of organs and tissues, and morphogenesis for development of metazoan body designs. Presently, another wave of evolutionary developmental science studies revealed that metazoans from cnidarians to vertebrates, despite their diverse morphologies, utilize a very comparable set of interpretation factors and flag pathway molecules for body development: these genes are sometimes collectively called a genetic toolbox.

Vertebrate Evolution by Donald R. Prothero Pdf

The first vertebrate animals appear in the fossil record over 520 million years ago. These lineages diversified and eventually crept ashore leading to further evolutionary divergence and the appearance of the familiar charismatic vertebrates of today. From the tiniest fishes, diminutive salamanders, and miniaturized lizards to gargantuan dinosaurs, enormous brontotheres, and immense whales, vertebrates have captured the imagination of the lay public as well as the most erudite academics. They are the among the best studied organisms. This book employs beautifully rendered illustrations of these diverse lineages along with informative text to document a rich evolutionary history. The prolific and best-selling author reveals much of the latest findings regarding the phylogenetic history of vertebrates without overwhelming the reader with pedantry and excessive jargon. Simultaneously, comprehensive and authoritative while being approachable and lucid, this book should appeal to both the scholar, the student, and the fossil enthusiast. Key Features Provides an up-to-date account of evolution of vertebrates Includes numerous beautiful color reconstructions of prehistoric vertebrates Describes extinct vertebrates and their evolutionary history Discusses and illustrates the first vertebrates, as well as familiar lineages of fishes, amphibians, reptiles, birds, and mammals Reviews mass extinctions and other important events in the diversification of vertebrates Related Titles Bard, J.

Animal Evolution by NATURAL SCIENCES and MATHEMATICS (500),ZOOLOGICAL SCIENCES (590) Pdf

Animal life, now and over the past half billion years, is incredibly diverse. Describing and understanding the evolution of this diversity of body plans - from vertebrates such as humans and fish to the numerous invertebrate groups including sponges, insects, molluscs, and the many groups of worms - is a major goal of evolutionary biology. In this book, a group of leading researchers adopt a modern, integrated approach to describe how current molecular genetic techniques and disciplines as diverse as palaeontology, embryology, and genomics have been combined, resulting in a dramatic renaissance in the study of animal evolution. The last decade has seen growing interest in evolutionary biology fuelled by a wealth of data from molecular biology. Modern phylogenies integrating evidence from molecules, embryological data, and morphology of living and fossil taxa provide a wide consensus of the major branching patterns of the tree of life; moreover, the links between phenotype and genotype are increasingly well understood. This has resulted in a reliable tree of relationships that has been widely accepted and has spawned numerous new and exciting questions that require a reassessment of the origins and radiation of animal life. The focus of this volume is at the level of major animal groups, the morphological innovations that define them, and the mechanisms of change to their embryology that have resulted in their evolution. Current research themes and future prospects are highlighted including phylogeny reconstruction, comparative developmental biology, the value of different sources of data and the importance of fossils, homology assessment, character evolution, phylogeny of major groups of animals, and genome evolution. These topics are integrated in the light of a 'new animal phylogeny', to provide fresh insights into the patterns and processes of animal evolution. Animal Evolution provides a timely and comprehensive statement of progress in the field for academic researchers requiring an authoritative, balanced and up-to-date overview of the topic. It is also intended for both upper level undergraduate and graduate students taking courses in animal evolution, molecular phylogenetics, evo-devo, comparative genomics and associated disciplines.

Amniote Origins by Stuart Sumida,Karen L.M Martin Pdf

Amniote Origins integrates modern systematic methods with studies of functional and physiological processes, and illustrates how studies of paleobiology can be illuminated by studies of neonatology. For this reason, comparative anatomists and physiologists, functional morphologists, zoologists, and paleontologists will all find this unique volume very useful. Inspired by the prospect of integrating fields that have long been isolated from one another, Amniote Origins provides a thorough and interdisciplinary synthesis of one of the classic transitions of evolutionary history.

The Vertebrate IntegumentVolume 1 by Theagarten Lingham-Soliar Pdf

The vertebrate integument arose about 450 million years ago as an ‘armour’ of dermal bony plates in small, jawless fish-like creatures, informally known as the ostracoderms. This book reviews the major changes that have occurred in the vertebrate integument from its beginnings to the present day. Critical questions concerning the origin, structure and functional biology of the bony integument are discussed and intrinsically linked to major steps in vertebrate evolution and phylogeny—the origin of jaws and the origin of teeth. The discussions include the origins of mineralization of major vertebrate skeletal components such as the dermatocranium, branchial arches and vertebral column. The advances that led to the origin of modern fishes and their phylogenetic development are reviewed and include the evolution of fins and replacement of the bony plates with several types of dermal scales. The evolution of reptiles saw a major transformation of the integument, with the epidermis becoming the protective outermost layer, from which the scales arose, while the dermis lay below it. The biological significance of the newly-evolved β-keratin in reptilian scales, among the toughest natural materials known, is discussed in the context of its major contribution to the great success of reptiles and to the evolution of feathers and avian flight. The dermis in many vertebrates is strengthened by layers of oppositely oriented cross-fibres, now firmly entrenched as a design principle of biomechanics. Throughout the book conventional ideas are discussed and a number of new hypotheses are presented in light of the latest developments. The long evolutionary history of vertebrates indicates that the significance of the Darwinian concept of “survival of the fittest” may be overstated, including in our own mammalian origins and that chance often plays a major role in evolutionary patterns. Extensive illustrations are included to support the verbal descriptions. Professor Theagarten Lingham-Soliar is in the Department of Life Sciences at the University of KwaZulu-Natal.

Before the Backbone by H. Gee Pdf

We cannot catechise our stony ichthyolites, as did the necromantic lady of the Arabian Nights did the coloured fishes of the lake which had once been a city, when she touched their dead bodies with her wand, and they straightaway raised their heads and rephed to her queries. We would have many a question to ask them if we could - questions never to be solved. Hugh Miller, The Old Red Sandstone When I started this book in 1991, the subject of vertebrate origins was fusty and unfashionable. Early drafts for this preface read like an extend ed complaint at the lot of traditional morphologists, cast aside by the march of modern molecular biology. But no longer - this book should reach you at a time of renewed inter est in the origin of the vertebrates, our own particular corner of creation. For although the topic has excited interest for well over a century, molec ular biology has only lately achieved the maturity necessary to test its predictions. As a legitimate field of study, it is fashionable again.
