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
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
Compared to other arthropods, crustaceans are characterized by an unparalleled disparity of body plans. Traditionally, the specialization of arthropod segments and appendages into distinct body regions has served as a convenient basis for higher classification; however, many relationships within the phylum Arthropoda still remain controversial.

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
A major synthesis of homology, written by a top researcher in the field Homology—a similar trait shared by different species and derived from common ancestry, such as a seal's fin and a bird’s wing—is one of the most fundamental yet challenging concepts in evolutionary biology. This groundbreaking book provides the first mechanistically based theory of what homology is and how it arises in evolution. Günter Wagner, one of the preeminent researchers in the field, argues that homology, or character identity, can be explained through the historical continuity of character identity networks—that is, the gene regulatory networks that enable differential gene expression. He shows how character identity is independent of the form and function of the character itself because the same network can activate different effector genes and thus control the development of different shapes, sizes, and qualities of the character. Demonstrating how this theoretical model can provide a foundation for understanding the evolutionary origin of novel characters, Wagner applies it to the origin and evolution of specific systems, such as cell types; skin, hair, and feathers; limbs and digits; and flowers. The first major synthesis of homology to be published in decades, Homology, Genes, and Evolutionary Innovation reveals how a mechanistically based theory can serve as a unifying concept for any branch of science concerned with the structure and development of organisms, and how it can help explain major transitions in evolution and broad patterns of biological diversity.

Book Description
"As a young and impetuous gradate student, I thought that sorting out the phylogeny of crustaceans would simply take but a little time and concerted effort to eventually reveal the truth. Everyone could then agree and further research would proceed apace. How naïve I was. First of all, I had never heard of Kurt Gödel's incompleteness theorems and hence the impossibility of achieving such an end. But even so, what progress we might have made turned out to take longer than anyone could have imagined, and the effort would be immense involving many people and a number of laboratories-and that task still continues. What no one could foresee in the 1960s was that the focus of everyone's attentions would completely transform. Traditional pure anatomy would be augmented with more sophisticated developmental genetic work. Concurrent with that effort molecular sequencing would become a remarkably effective tool. And with these new sources of data, the concept of "crustaceans" would yield to a new construct-Pancrustacea-within which the arthropods that we referred to by the name of "Crustacea" became a series of monophyletic smaller groups that mark a paraphyletic transition from a mandibulate ancestor all the way up to a crown group that few in the 1960s expected-Hexapoda emerged within the pancrustaceans"--

Book Description
Palaeoentomology represents the interface between two huge scientific disciplines: palaeontology – the study of fossils, and entomology – the study of insects. However, fossils rarely feature extensively in books on insects, and likewise, insects rarely feature in books about fossils. Similarly, college or university palaeontology courses rarely have an entomological component and entomology courses do not usually consider the fossil record of insects in any detail. This is not due to a lack of insect fossils. The fossil record of insects is incredibly diverse in terms of taxonomic scope, age range (Devonian to Recent), mode of preservation (amber and rock) and geographical distribution (fossil insects have been recorded from all continents, including Antarctica). In this book the authors aim to help bridge the palaeontology–entomology gap by providing a broadly accessible introduction to some of the best preserved fossil insects from a wide range of deposits from around the globe, many of which are beautifully illustrated by colour photographs. Also covered are insect behaviour and ecology in the fossil record, sub-fossil insects, trace fossils and insect species longevity. Just as insects are useful as ecological indicators today, the same can be expected to be true of the past. Such applications of the insect fossil record are briefly discussed. It is hoped that this book will encourage a few future researchers to enter the fascinating realm of palaeoentomology and to this end there is a section on how to become a palaeoentomologist. However, it is aimed at a much broader audience – those with an interest in fossils and/or insects in general, who will no doubt marvel at the diversity and excellent preservation of the fossils illustrated.
