Abstract

The Arthropoda is by far the largest living phylum, comprising over 1.2 million living species, and its unique evolutionary success is the primary focus for this up-to-date and comprehensive overview of the biology of the group.  This astonishing species richness is matched by a spectacular diversity in body forms and adaptations.  To counter the largely unavoidable trend towards increased specialization within a particular group, this volume adopts a comparative viewpoint across the entire phylum, encompassing both extant and fossil forms.  The phylum-wide perspective allows us to appreciate the wave of recent advances in knowledge of arthropod biology and evolution and to identify emerging themes and priorities for future research. As ever in the history of science, this wave of advances is driven by the rapid development of new methods and techniques.  New methods of extracting and studying fossils have vastly improved understanding of Palaeozoic arthropods.  New non-invasive, non-destructive techniques, such as micro-computed tomography, have revolutionised anatomical analysis and imaging. Arthropod comparative genomics is still in its infancy but high-throughput sequencing together with next-generation sequencing has facilitated spectacular growth in volumes of sequence data, which in turn has driven advances in bioinformatics. These novel methods have generated a wealth of data which has been critically reviewed by the chapter authors, to provide a new perspective on arthropod biology and evolution. The concise factual summaries and the questions articulated in this book will be of interest to evolutionary biologists, palaeontologists, developmental geneticists and invertebrate zoologists. It will be of special interest to advanced graduate and post-graduate students and have the potential to stimulate younger researchers to address questions in arthropod biology from the vantage point of a phylum-wide comparative perspective.

Abstract

Stephen J. Gould’s greatest contribution to science is a revised version of the theory of evolution which offers today a useful framework for understanding progress in many evolutionary fields. His intuitions about the conjunction of evolution and development, the role of ecological factors in speciation, the multi-level interpretation of the units of selection, and the interplay between functional pressures and constraints all represent fruitful lines of experimental research. His opposition to the progressive representations of evolution, the gene-centered view of natural history, or the adaptationist “just-so stories” has also left its mark on current biology. In May 2012, at the Istituto Veneto di Scienze, Lettere ed Arti in Venice, an international panel of scientists and philosophers discussed Stephen J. Gould’s legacy, ten years after his death. This book presents a selection of those contributions, chosen for their interest and importance. A broad range of themes are covered: Gould’s contribution to evolutionary theory, including the concept of punctuated equilibria and the importance of his pluralism; the Gouldian view of genome and development; Gould’s legacy in anthropology; and, finally, the significance of his thought for the human sciences. This book provides a fascinating appraisal of the cultural legacy of one of the world’s greatest popular writers in the life sciences. This is the first time that scientists including some of Gould’s personal friends and co-authors of papers of momentous importance such as Niles Eldredge have come together to strike a balanced view of Gould's intellectual heritage.
