Book Description
This volume is the result of a NATO Advanced Study Institute held in England at Kingswood Hall of Residence, Royal Holloway College (London University), Surrey, during the last two weeks of July, 1976. The ASI was organized within the guide lines laid down by the Scientific Affairs Division of the North Atlantic Treaty Organization. During the past two decades, significant advances have been made in our understanding of vertebrate evolution. The purpose of the Institute was to present the current status of our know ledge of vertebrate evolution above the species level. Since the subject matter was obviously too broad to be covered adequately in the limited time available, selected topics, problems, and areas which are applicable to vertebrate zoology as a whole were reviewed. The program was divided into three areas: (1) the theory and methodology of phyletic inference and approaches to the an alysis of macroevolutionary trends as applied to vertebrates; (2) the application of these methodological principles and an alytical processes to different groups and structures, particular ly in anatomy and paleontology; (3) the application of these re sults to classification. The basic principles considered in the first area were outlined in lectures covering the problems of character analysis, functional morphology, karyological evidence, biochemical evidence, morphogenesis, and biogeography.

Book Description
The factors that influenced the evolution of the vertebrates are compared with the importance of variation and selection that Darwin emphasised in this broad study of the patterns and forces of evolutionary change.

Book Description
A multi-author volume Major Events in Early Vertebrate Evolution examines the origin and early evolution of the backboned animals (vertebrates)-the group which comprises all fishes, amphibians, reptiles, birds and mammals, including ourselves. This volume draws together evidence from fossils, genes, and developmental biology (the study of how embry

Book Description
How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods evolve from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the 500-million-year history of vertebrate life. And with the aid of new techniques and approaches across a range of fields—work spanning multiple levels of biological organization from DNA sequences to organs and the physiology and ecology of whole organisms—we are now beginning to unravel the confounding evolutionary mysteries contained in the structure, genes, and fossil record of every living species. This book gathers a diverse team of renowned scientists to capture the excitement of these new discoveries in a collection that is both accessible to students and an important contribution to the future of its field. Marshaling a range of disciplines—from paleobiology to phylogenetics, developmental biology, ecology, and evolutionary biology—the contributors attack particular transformations in the head and neck, trunk, appendages such as fins and limbs, and the whole body, as well as offer synthetic perspectives. Illustrated throughout, Great Transformations in Vertebrate Evolution not only reveals the true origins of whales with legs, fish with elbows, wrists, and necks, and feathered dinosaurs, but also the relevance to our lives today of these extraordinary narratives of change.

Book Description
New discoveries of ancient vertebrates, filling in gaps in the fossil record, are quickly eroding the traditionally recognized differences between the principal groups of vertebrates—for example, between dinosaurs and birds—and radically changing our understanding of the evolutionary history of the major group of animals to which our species belongs. This book describes this changing scientific landscape and contributes to the revolution in our knowledge of the developmental mechanisms that underlie evolutionary transformation.

Book Description
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.

Book Description
When did the first vertebrates emerge, and how did they differ from their invertebrate ancestors? When did vertebrates evolve jaws, paired fins, pattern vision, or a neocortex? How have evolutionary innovations such as these impacted vertebrate behavior and success? Georg Striedter and Glenn Northcutt answer these fundamental questions about all major vertebrate lineages. Highlighting the key innovations of each major taxonomic group, they review how evolutionary changes in vertebrate genetics, anatomy, and physiology are reflected in the nervous system. This highly accessible book allows readers to explore a vast expanse of scientific knowledge, ranging from paleoecology to comparative molecular biology, sensory biology to neural circuit evolution, and fossil anatomy to animal behavior. Brains Through Time examines how vertebrate nervous systems evolved in conjunction with other organ systems and the planet's ecology. Surveying an enormous range of information on genes and proteins, sensory and motor systems, central neural circuits, physiology, and animal behavior, the authors reconstruct the major changes that occurred as vertebrates emerged and then diversified. In the process, readers are transported back in time to key stages of vertebrate evolution, notably the origin of vertebrates, the evolution of paired fins and jaws, the transition to life on land, and the origins of warm-blooded mammals and birds.

Book Description
Complex Organismal Functions: Integration and Evolution in Vertebrates D. B. Wake G. Roth Editors The complexity of forms and functions of organisms studied in an evolutionary context prompts a fundamental question of modern biology: how did complex functional systems, apparently stabilized by high degrees of integration, evolve to their present diversity? This and related questions were discussed by 48 distinguished scientists from many fields of vertebrate biology, including functional and comparative morphologists, neurobiologists, reproductive biologists and endocrinologists, developmental biologists, ecologists, ethologists, population geneticists, and theorists, at a Dahlem Workshop. This volume is a report of that meeting. The major areas of discussion were: evolutionary diversification of feeding mechanisms; evolution of locomotor systems; trends in reproductive biology, especially the repeated evolution of vertebrate viviparity; and alternative and complementary concepts of the production of evolutionary novelties and patterns. These topics reflect the excitement and dynamism of current debate in evolutionary biology and constitute a cohesive point of departure for further research.
