Representing the state of the art in evolutionary paleobiology, this book provides a much-needed overview of this rapidly changing field. An influx of ideas and techniques both from other areas of biology and from within paleobiology itself have resulted in numerous recent advances, including increased recognition of the relationships between ecological and evolutionary theory, renewed vigor in the study of ecological communities over geologic timescales, increased understanding of biogeographical patterns, and new mathematical approaches to studying the form and structure of plants and animals. Contributors to this volume—a veritable who's who of eminent researchers—present the results of original research and new theoretical developments, and provide directions for future studies. Individually wide ranging, these papers all share a debt to the work of James W. Valentine, one of the founders of modern evolutionary paleobiology. This volume's unified approach to the study of life on earth will be a major contribution to paleobiology, evolution, and ecology.

On the Origin of Phyla

By: James W. Valentine

Owing its inspiration and title to On the Origin of Species, James W. Valentine's ambitious book synthesizes and applies the vast treasury of theory and research collected in the century and a half since Darwin's time. By investigating the origins of life's diversity, Valentine unlocks the mystery of the origin of phyla. One of the twentieth century's most distinguished paleobiologists, Valentine here integrates data from molecular genetics, evolutionary developmental biology, embryology, comparative morphology, and paleontology into an analysis of interest to scholars from any of these fields. He begins by examining the sorts of evidence that can be gleaned from fossils, molecules, and morphology, then reviews and compares the basic morphology and development of animal phyla, emphasizing the important design elements found in the bodyplans of both living and extinct phyla. Finally, Valentine undertakes the monumental task of developing models to explain the origin and early diversification of animal phyla, as well as their later evolutionary patterns. Truly a magnum opus, On the Origin of Phyla will take its place as one of the classic scientific texts of the twentieth century, affecting the work of paleontologists, morphologists, and developmental, molecular, and evolutionary biologists for decades to come. "A magisterial compendium . . . . Valentine offers a judicious evaluation of an astonishing array of evidence."—Richard Fortey, New Scientist "Truly a magnum opus, On the Origin of Phyla has already taken its place as one of the classic scientific texts of the twentieth century, affecting the work of paleontologists, morphologists, and developmental, molecular, and evolutionary biologists for decades to come."—Ethology, Ecology & Evolution "Valentine is one of the Renaissance minds of our time. . . . Darwin wisely called his best-known work On the Origin of the Species; the origin of the phyla is an even stickier problem, and Valentine deserves credit for tackling it at such breadth . . . . A magnificient book."—Stefan Bengtson, Nature

The Land and the People of Nineteenth-Century Cork

The Rural Economy and the Land Question

By: James S. Donnelly Jr

First published in 1975. Using estate records, local newspapers and parliamentary papers, this book focuses upon two central and interrelated subjects – the rural economy and the land question – from the perspective of Cork, Ireland’s southernmost country. The author examines the chief responses of Cork landlords, tenant farmers and labourers to the enormous difficulties besetting them after 1815. He shows how the great famine of the late 1840s was in many ways an economic and social watershed because it rapidly accelerated certain previous trends and reversed the direction of others. He also rejects the conventional view of the land war of the 1880s, arguing that in Cork it was essentially a ‘revolution of rising expectations’, in which tenant farmers struggled to preserve their substantial material gains since 1850 by using the weapons of ‘agrarian trade unionism’, civil disobedience and unprecedented violence. This title will be of interest to students of rural history and historical geography.
