Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Ancestry of Vertebrates: As a Means of Understanding the Principal Features of Their Structure and Development Those who have read the book to the end will admit that this theory, to say the least of it, merits earnest consideration. They will admit that, unlike most other similar theories, it not only serves to explain known facts but that also its application has advanced us further in several respects. Of these I will mention here only the problem of the hypoglossus and its relation to the gill-slits and the cranium (cf. Plate and the results given in the last chapter. In the treating of the different problems, I have tried each time to give the reader first an idea of the divergent opinions and the confusion often prevailing. Though this does not make the reading of the book easier and more agreeable - problems having been made often much more complicated by the investigators than they are in reality I have thought it advisable to do so in order to emphasize the value of a means of escaping from this confusion. The expressing of a persons thoughts correctly in a foreign language is no easy matter. I 'am greatly indebted, therefore, to Mr. Humphreys, officer of the Royal Flying Corps who was interned in The Hague during the year 1918. For having gone over with me the whole article, and to Mr. Moon, engineer of Batavia, for having once more reread with me the proofs If in spite of this the English be not yet perfect, I trust that these imperfections, if any, will not give rise to any misunderstandings.

This book was released on 2014-02-18 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Brains Through Time written by Georg F. Striedter and published by Oxford University Press. This book was released on 2019-12-24 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Vertebrate Endocrinology written by David O. Norris and published by Elsevier. This book was released on 2006-11-27 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the only books to discuss all vertebrates, the fourth edition of Vertebrate Endocrinology has been completely reorganized and updated to explore the intricate mechanisms that control human physiology and behavior as well as that of other vertebrate animals. Perfect for students in endocrinology, zoology, biology and physiology, it allows readers to gain both an understanding of the intricate relationships among all of the body systems and their regulation by hormones and other bioregulators, but also a sense of their development through evolutionary time as well as the roles of hormones at different stages of an animal's life cycle. Chapters have been reorganized to more closely follow traditional classroom presentation and extensive suggested readings are included at the end of each chapter allowing the reader to obtain further information as well as connect concepts to the literature on which the book is based. For the first time, this edition features four-color illustrations. - Provides a complete overview of the endocrine system of vertebrates by first emphasizing the mammalian system as the basis of most terminology and understanding of endocrine mechanisms and then applies that to non-mammals - Introduces the reader to suitable concepts and explanation of jargon so that the reader will be able to delve directly into the primary literature on any endocrine-related topic with a background that will aid in their interpretation of new information - Revised and updated chapter on The Molecular Bases for Chemical Regulation that now includes more evolutionary data - Includes information on endocrine disrupting chemicals and their implications on the health of wildlife and humans
