Book Description
Gregory Edgecombe has assembled premier specialists in the study of arthropods, each of whom addresses a major issue in arthropod diversity by reviewing evidence of key fossils from a common perspective and examining the interplay between extinct and extant species through inference of the structure of the arthropod evolutionary tree.With the most complete collection of modern perspectives on the history of Arthropoda, this volume advances the current debate on paleontology's role in discovering life's hierarchy. Of interest to specialists in a wide range of fields including paleontology, petroleum geology, oceanography, and entomology, Arthropod Fossils and Phylogeny will be the standard general reference on arthropod paleontology for years to come.

Book Description
Since its discovery in 1909 by Charles Doolittle Walcott, then Secretary of the Smithsonian Institution, the Burgess Shale in the Canadian Rocky Mountains has fascinated both scientists and the public with its plethora of weird wonders - life forms of the past so unfamiliar they cannot easily be assigned to known taxonomic groups. This century's most significant invertebrate fossil discovery, the Burgess Shale provides an unprecedented window into the explosive evolution during the Cambrian period that began about 540 million years ago, one of the most enigmatic episodes in the history of life. This book provides the first comprehensive set of illustrations of the extraordinary life forms revealed in the Burgess Shale. In addition to the more common fossilized hard skeletons, the Burgess Shale preserved the soft parts of these organisms, which provide a key to understanding the early evolution of the major groups of animals that inhabit the earth today. The Fossils of the Burgess Shale shows much remarkable detail - including digestive tracts and other internal organs - of creatures preserved in particles of mud fine enough to penetrate every crack and unevenness. The book begins with the history of exploration and research in the Burgess Shale, the geologic setting and preservation of the fossils, and a discussion of the Cambrian radiation, the period when almost all the major phyla of animals evolved. These introductory chapters are followed by 199 high-quality photographs and line drawings with detailed species accounts that describe important features of each specimen, as well as the ecology and taxonomy of each group. A complete list of all currently accepted species described from the Burgess Shale and a comprehensive bibliography follow the illustrations. The Fossil of the Burgess Shale is a compendium of fascinating Cambrian treasures that offer a rare glimpse into the nature of early life on our planet. They have figured prominently in recent evolutionary debates. The National Museum of Natural History, which houses more than 65,000 fossils collected by Walcott from the Burgess Shale, will open a new exhibition of the specimens in 1995.

Book Description
Although evolutionary developmental biology is a new field, its origins lie in the last century; the search for connections between embryonic development (ontogeny) and evolutionary change (phylogeny) has been a long one. Evolutionary developmental biology is however more than just a fusion of the fields of developmental and evolutionary biology. It forges a unification of genomic, developmental, organismal, population and natural selection approaches to evolutionary change. It is concerned with how developmental processes evolve; how evolution produces novel structures, functions and behaviours; and how development, evolution and ecology are integrated to bring about and stabilize evolutionary change. The previous edition of this title, published in 1992, defined the terms and laid out the field for evolutionary developmental biology. This field is now one of the most active and fast growing within biology and this is reflected in this second edition, which is more than twice the length of the original and brought completely up to date. There are new chapters on major transitions in animal evolution, expanded coverage of comparative embryonic development and the inclusion of recent advances in genetics and molecular biology. The book is divided into eight parts which: place evolutionary developmental biology in the historical context of the search for relationships between development and evolution; detail the historical background leading to evolutionary embryology; explore embryos in development and embryos in evolution; discuss the relationship between embryos, evolution, environment and ecology; discuss the dilemma for homology of the fact that development evolves; deal with the importance of understanding how embryos measure time and place both through development and evolutionarily through heterochrony and heterotrophy; and set out the principles and processes that underlie evolutionary developmental biology. With over one hundred illustrations and photographs, extensive cross-referencing between chapters and boxes for ancillary material, this latest edition will be of immense interest to graduate and advanced undergraduate students in cell, developmental and molecular biology, and in zoology, evolution, ecology and entomology; in fact anyone with an interest in this new and increasingly important and interdisciplinary field which unifies biology.
