Book Description
Embryology and Phylogeny in Annelids and Arthropods describes the embryology of segmented invertebrates, utilizing morphological facts of embryonic development in the furtherance of speculations on phylogenetic relationships. This book begins with an introduction to embryology and phylogeny, followed by a discussion on the experimental embryology of animals groups, such as polychaetes, oligochaetes and leeches, onychophorans, myriapods, apterygote and pterygote insects, crustaceans, and chelicerates. The cleavage, gastrulation, and basic pattern of development of these invertebrates are also provided. This text concludes with a presentation of the onychophoran-myriapod-hexapod assemblage or Uniramia. This publication is recommended for experimental embryologists researching on the embryonic development in annelids and arthropods.

Book Description
The arthropods contain more species than any other animal group, but the evolutionary pathways which led to their current diversity are still an issue of controversy. Arthropod Relationships provides an overview of our current understanding, responding to the new data arising from sequencing DNA, the discovery of new Cambrian fossils as direct evidence of early arthropod history, and developmental genetics. These new areas of research have stimulated a reconsideration of classical morphology and embryology. Arthropod Relationships is the first synthesis of the current debate to emerge: not since the volume edited by Gupta was published in 1979 has the arthropod phylogeny debate been, considered in this depth and breadth. Leaders in the various branches of arthropod biology have contributed to this volume. Chapters focus progressively from the general issues to the specific problems involving particular groups, and thence to a consideration of embryology and genetics. This wide range of disciplines is drawn on to approach an understanding of arthropod relationships, and to provide the most timely account of arthropod phylogeny. This book should be read by evolutionary biologists, palaeontologists, developmental geneticists and invertebrate zoologists. It will have a special interest for post-graduate students working in these fields.

Book Description
Annelida is a diverse group of animals, commonly referred to as segmented worms and currently comprising around 14000 described species. Found in most marine and freshwater areas, annelids have also successfully occupied many subterranean habitats. This volume documents annelid reproduction in the context of their phylogenetic relationships. It pre

Book Description
More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.

Book Description
Annelids offer a diversity of experimentally accessible features making them a rich experimental subject across the biological sciences, including evolutionary development, neurosciences and stem cell research. This volume introduces the Annelids and their utility in evolutionary developmental biology, neurobiology, and environmental/ecological studies, including extreme environments. The book demonstrates the variety of fields in which Annelids are already proving to be a useful experimental system. Describing the utility of Annelids as a research model, this book is an invaluable resource for all researchers in the field.

Book Description
Immunology of Annelids provides a state-of-the-art review of the biological and biochemical processes involved in defense reactions of annelids. The book covers phylogeny, taxonomy, and fundamental body structure to provide basic information essential to developing a full understanding of the defense system of an organism. Physiological aspects of the relationship between the immune systems and cells and their limitations are discussed in detail, and the role of cells in cellular defense, transplantation, and humoral defenses is explained. The importance of annelids and their defense reaction from the phylogenetic standpoint is examined in a chapter comparing vertebrate and invertebrate defense strategies. Immunology of Annelids is a practical reference for cell biologists, immunologists, evolutionary and developmental biologists, and other researchers who need insight into the development and hierarchy of immune reactions.

Book Description
“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
