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
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
How could a structure as complex as the vertebrate brain develop from the simplest multicellular animals? Natural selection offers an impeccable mechanism for the gradual transformation of species, but even Darwin sometimes expressed doubts about the origin of highly complex structures. Following an approach that has been termed "developmental evolutionary genetics," this book seeks to establish a correspondence between embryological processes and the phylogenetic history of an organism.

Book Description
The emphasis in this volume is on the structure and functional design of the integument. The book starts with a brief introduction to some basic principles of physics (mechanics) including Newton’s Three Laws of Motion. These principles are subsequently used to interpret the problems animals encounter in motion. It is in only the last 40 or so years that we have begun to understand how important a role the integument plays in the locomotion of many marine vertebrates. This involves the crossed-fiber architecture, which was first discovered in a classic study on nemertean worms. As a design principle we see that the crossed-fiber architecture is ubiquitous in nature. Research on some of the most dynamic marine vertebrates of the oceans – tuna, dolphins and sharks, and the extinct Jurassic ichthyosaurs – shows precisely how the crossed-fiber architecture contributes to high-speed swimming and (in lamnid sharks) may even aid in energy conservation. However, this design principle is not restricted to animals in the marine biota but is also found as far afield as the dinosaurs and, most recently, has been revealed as a major part of the microstructure of the most complex derivative of the integument, the feather. We see that a variety of phylogenetically diverse vertebrates take to the air by using skin flaps to glide from tree to tree or to the ground, and present detailed descriptions of innovations developed in pursuit of improved gliding capabilities in both extinct and modern day gliders. But the vertebrate integument had even greater things in store, namely true or flapping flight. Pterosaurs were the first vertebrates to use the integument as a membrane in true flapping flight and these interesting extinct animals are discussed on the basis of past and cutting-edge research , most intriguingly with respect to the structure of the flight membrane. Bats, the only mammals that fly, also employ integumental flight membranes. Classic research on bat flight is reviewed and supplemented with the latest research, which shows the complexities of the wing beat cycle to be significantly different from that of birds, as revealed by particle image velocimetry. The book’s largest chapter is devoted to birds, given that they make up nearly half of the over 22,000 species of tetrapods. The flight apparatus of birds is unique in nature and is described in great detail, with innovative research highlighting the complexity of the flight structures, bird flight patterns, and behavior in a variety of species. This is complimented by new research on the brains of birds, which shows that they are more complex than previously thought. The feather made bird flight possible, and was itself made possible by β-keratin, contributing to what may be a unique biomechanical microstructure in nature, a topic discussed in some depth. A highly polarized subject concerns the origin of birds and of the feather. Alleged fossilized protofeathers (primal simple feathers) are considered on the basis of histological and taphonomic investigative studies in Chapter 6. Finally, in Chapter 7 we discuss the controversies associated with this field of research. Professor Theagarten Lingham-Soliar works at the Nelson Mandela Metropolitan University, Port Elizabeth and is an Honorary Professor of Life Sciences at the University of KwaZulu-Natal.

Book Description
The paleontologist and professor of anatomy who co-discovered Tiktaalik, the “fish with hands,” tells a “compelling scientific adventure story that will change forever how you understand what it means to be human” (Oliver Sacks). By examining fossils and DNA, he shows us that our hands actually resemble fish fins, our heads are organized like long-extinct jawless fish, and major parts of our genomes look and function like those of worms and bacteria. Your Inner Fish makes us look at ourselves and our world in an illuminating new light. This is science writing at its finest—enlightening, accessible and told with irresistible enthusiasm.
