Book Description
So much has to be crammed into today's biology courses that basic information on animal groups and their evolutionary origins is often left out. This is particularly true for the invertebrates. The second edition of Janet Moore's An Introduction to the Invertebrates fills this gap by providing a short updated guide to the invertebrate phyla, looking at their diverse forms, functions and evolutionary relationships. This book first introduces evolution and modern methods of tracing it, then considers the distinctive body plan of each invertebrate phylum showing what has evolved, how the animals live, and how they develop. Boxes introduce physiological mechanisms and development. The final chapter explains uses of molecular evidence and presents an up-to-date view of evolutionary history, giving a more certain definition of the relationships between invertebrates. This user-friendly and well-illustrated introduction will be invaluable for all those studying invertebrates.

Book Description
The purpose of this book, now in its third edition, is to introduce the morphology of vertebrates in a context that emphasizes a comparison of structire and of the function of structural units. The comparative method involves the analysis of the history of structure in both developmental and evolutionary frameworks. The nature of adaptation is the key to this analysis. Adaptation of a species to its environment, as revealed by its structure, function, and reproductive success, is the product of mutation and natural selection–the process of evolution. The evolution of structure and function, then, is the theme of this book which presents, system by system, the evolution of structure and function of vertebrates. Each chapter presents the major evolutionary trends of an organ system, with instructions for laboratory exploration of these trends included so the student can integrate concept with example.

Book Description
Animal Evolution is a complete analysis of the evolutionary interrelationships and myriad diversity of the animal kingdom. Using modern phylogenetic reasoning based on characters from an extensive review of morphology, including ultrastructure, and embryology, each phylum is analysed to ascertain its monophyly and hence its ancestral characters. These ancestral characters are then used to construct a complete phylogenetic tree of the extant animal phyla. This new edition of Animal Evolution brings the subject fully up to date including some new ideas and emphases, as well as new bibliographic data. It also includes new chapters on the use of computer programmes and on the use of the new molecular techniques to create phylogenies, both techniques that have grown in prevalence in the field since the first edition was published. Illustrated throughout with finely detailed line drawings and clear diagrams. From reviews of the first edition of Animal Evolution: 'A clear and engaging style exemplified by a series of superbly concise descriptions of the phyla.... These are complemented by excellent illustrations.... The volume belongs on every biologist's bookshelf.' Simon Conway- Morris, Nature 'Texts like these constitute the very cream of taxonomic literature.... It really is a joy to read... and in my opinion it constitutes a highly recommended book for all zoologists. I think it is also particularly suited for seminars on animal classification for both undergraduate and graduate students.' JC von Vaupel Klein, Crustaceana 'I highly recommend this book as a fascinating theory of animal relationships, and an excellent summary of the phylogenetically informative aspects of the biology of the whole animal kingdom.'

Book Description
This volume of the Handbook of Zoology summarizes "small" groups of animals across the animal kingdom. Dicyemida and Orthonectida are enigmatic parasites, formerly united as "Mesozoa" and their position among the multicellular animals is still not known with certainty. Placozoa are small, flat marine animals which provide important information on metazoan evolution. Comb jellies (Ctenophora) are esthetically fascinating animals which cause considerable discussion about their phylogenetic position. Seisonida are closely related to rotifers and acanthocephalans. Cycliophora were discovered and described as one of the last higher taxa and surprise by their complex life cycle. Kamptozoa (= Entoprocta) are small sessile animals in the sea and sometimes also in freshwater. Arrow worms (Chaetognatha) play an important role as predators in the plankton, but they also include benthic forms. Pterobranchia and acorn worms (Enteropneusta) belong to the deuterostomia and are related to echinoderms. In particular enteropneusts play an important role in understanding deuterostome evolution. These chapters provide up to date reviews of these exiting groups with reference to the important literature and therefore serves as an important source of information.
