Frederick Orpen Bower (1855-1948) was a renowned botanist best known for his research on the origins and evolution of ferns. Appointed Regius Professor of Botany at the University of Glasgow in 1885, he became a leading figure in the development of modern botany and the emerging field of paleobotany, devising the interpolation theory of the life cycle in land plants. First published between 1923 and 1928 as part of the Cambridge Botanical Handbook series, The Ferns was the first systematic classification of ferns according to anatomical, morphological and developmental features. In this three-volume work Bower analyses the major areas of comparison between different species, describes primitive and fossil ferns and compares these species to present-day fern species, providing a comprehensive description of the order. Volume 1 describes and analyses the features of ferns which Bower uses in his system of classification.

Ernst Mayr is perhaps the most distinguished biologist of the twentieth century, and "Systematics and the Origin of Species" may be one of his greatest and most influential books. This classic study, first published in 1942, helped to revolutionize evolutionary biology by offering a new approach to taxonomic principles and correlating the ideas and findings of modern systematics with those of other life science disciplines. This book is one of the foundational documents of the "Evolutionary Synthesis." It is the book in which Mayr pioneered his new concept of species based chiefly on such biological factors as interbreeding and reproductive isolation, taking into account ecology, geography, and life history. In his new introduction for this edition, Mayr reflects on the place of this enduring work in the subsequent history of his field.

How does death help us understand the living? Death is more than the last event of life; it is interwoven into our growth, development, protection against disease, and more. It influences the direction of entire species via the cycle of a lifespan, and it involves asking many fascinating questions. How do we differentiate between life and death, though? How do we know when a person, animal, or cell is really dead? How much grey area is there in the science? Why do we age? Can we do anything about it? Scientifically, there's much we can learn about a living thing from its cells. In all living things, cells seem to carry "death" gene programs. Some living organisms have created systems to use these to their own advantage. Humans, for example, use the death of specific cells to hone our immune system and to give us fingernails and hair. Perhaps the most dramatic use occurs during the metamorphosis of insects and frogs. Even single-celled organisms use "quorum sensing" to eliminate some cells to ensure the overall survival of their colony in harsh environments. Thus, there is more to death than just dying. This latest book from science writer Gary C. Howard ties together the many ways that death helps us understand life. He synthesizes the involvement and relation of cells, tissues, organisms, and populations, explaining what happens at the end of life. Between discussions about popular topics such as the ethics of extending life and cell regeneration, Howard also answers fascinating questions about life and death. The resulting book examines how the end of life is determined and what we can learn from this process.

This book examines the relationship between classification and evolutionary theory, with reference to the competing schools of taxonomic thinking. Emphasis is placed on one of these schools, the transformed cladists, who have attempted to reject all evolutionary thinking in classification and to cast doubt on evolution in general. The author examines the limits to this line of thought from a philosophical and methodological perspective rather than from a biological viewpoint. He concludes that transformed cladistics does not achieve what it claims and that it either implicity assumes a Platonic World View, or is unintelligible without taking into account evolutionary processes - the very processes it claims to reject. Through this analysis the author attempts to formulate criteria, of an objective and consistent nature, that can be used to judge competing methodologies and theories without resorting to any particular theoretical standpoint for justification. Philosophers of science, zoologists interested in taxonomy and evolutionary biologists will find this a compelling study of an area of biological thought that has been attracting a great deal of attention.

The question of whether biologists should continue to use the Linnaean hierarchy has been a hotly debated issue. Invented before the introduction of evolutionary theory, Linnaeus's system of classifying organisms is based on outdated theoretical assumptions, and is thought to be unable to provide accurate biological classifications. Marc Ereshefsky argues that biologists should abandon the Linnaean system and adopt an alternative that is more in line with evolutionary theory. He traces the evolution of the Linnaean hierarchy from its introduction to the present. He illustrates how the continued use of this system hampers our ability to classify the organic world, and then goes on to make specific recommendations for a post-Linnaean method of classification. Accessible to a wide range of readers by providing introductory chapters to the philosophy of classification and the taxonomy of biology, the book will interest both scholars and students of biology and the philosophy of science.

Systematics has developed rapidly during the past two decades. A multitude of new methods and contributions from a diversity of biological fields including molecular genetics and developmental biology have provided a wealth of phylogenetic hypotheses, some confirming traditional views others contradicting them. Despite such inconsistencies, it is now possible to recognize robust regions of a 'tree of life' and also to identify problematic areas which have yet to be resolved. This is the first book to apply the current state of phylogeny to an evolutionary interpretation of animal organ systems and body architecture, providing alternative theories in those cases of continuing controversy.
Organs do not appear suddenly during evolution; instead they are composed of far simpler structures. In some cases it is even possible to trace particular molecules or physiological pathways as far back as pre-animal history. What emerges is a fascinating picture, showing how animals have combined ancestral and new elements in novel ways to form constantly changing responses to environmental requirements.
The Evolution of Organ Systems starts with a general overview of current animal phylogeny, followed by review of general body organization including symmetry, anteroposterior axis, dorsoventral axis, germ layers, segmentation, and skeletons. Subsequent chapters then provide a detailed description of the individual organ systems themselves - integument, musculature, nervous system, sensory organs, body cavities, excretory system, circulatory system, respiratory system, intestinal system, gonads and gametes. Generously illustrated throughout, this accessible text is suitable for both upper levelundergraduate and graduate students taking courses in animal evolution, organogenesis, animal anatomy, zoology and systematics. It will also be a valuable reference tool for those professional researchers in these fields requiring an authoritative, balanced and up-to-date overview of the topic.

The field of molecular evolution has experienced explosive growth in recent years due to the rapid accumulation of genetic sequence data, continuous improvements to computer hardware and software, and the development of sophisticated analytical methods. The increasing availability of large genomic data sets requires powerful statistical methods to analyze and interpret them, generating both computational and conceptual challenges for the field.
Computational Molecular Evolution provides an up-to-date and comprehensive coverage of modern statistical and computational methods used in molecular evolutionary analysis, such as maximum likelihood and Bayesian statistics. Yang describes the models, methods and algorithms that are most useful for analysing the ever-increasing supply of molecular sequence data, with a view to furthering our understanding of the evolution of genes and genomes. The book emphasizes essential concepts rather than mathematical proofs. It includes detailed derivations and implementation details, as well as numerous illustrations, worked examples, and exercises. It will be of relevance and use to students and professional researchers (both empiricists and theoreticians) in the fields of molecular phylogenetics, evolutionary biology, population genetics, mathematics, statistics and computer science. Biologists who have used phylogenetic software programs to analyze their own data will find the book particularly rewarding, although it should appeal to anyone seeking an authoritative overview of this exciting area of computational biology.

Until now, individuals wishing to identify British insects have found it difficult to track down the specialist keys published in obscure literature, whereas the popular guides are often misleadingly simplistic, covering only a fraction of the species. This book bridges the gap, providing expert guidance through the taxonomic maze. It contains an introduction to each group of organisms, and over 2000 references selected as being the most useful and up-to-date for accurate identification, together with notes on their relevance and coverage. A further chapter covers the understanding and retrieval of scientific references, with advice on using libraries and other information services. This will be an essential reference book for anyone involved in insect and arachnid identification, from interested amateurs to professionals dealing with unfamiliar groups.

This book presents current knowledge of the early vertebrates--mainly fish, but including some terrestrial creatures--which lived about 250 to 470 million years ago. The work focuses on anatomical and phylogenetic questions, but includes information on fossil discovery and preparation, as well as the analysis of the characteristics from which their relationships may be reconstructed. The author addresses both new and old problems in the evolution of certain anatomical details and deals briefly with the animals' way of life, extinction, and former distribution. The book is the first in its field to use a cladistic approach. For each major vertebrate group, the reader will find a diagram of relationships, or cladogram, with a selection of characters at each node, and a succinct phylogenetic classification.

Inspired by the pace of change in the taxonomy of the aerobic endospore-forming bacteria, the "Bacillus 2000" symposium on which this book is based was held in Bruges, Belgium, in August 2000, and was supported by the Federation of European Microbiological Societies, the Belgian Society for Microbiology, and several commercial sponsors. Bringing taxonomists interested in Bacillus and its relatives together with people who work with these organisms in medicine, agriculture, and industry, allowed those attending to appreciate the overlaps and interactions of their areas of expertise, in the absence of any comprehensive treatment of the current systematics of the group.

The meeting was a great success, and has resulted in the production of these proceedings, Applications and Systematics of Bacillus and Relatives, providing an up-to-date and comprehensive treatise on the classification, identification and applications of the aerobic endospore-forming bacteria; it is an essential reference for all microbiologists interested in these organisms.
Valuable reference work for all those interested in the systematics of Bacillus and its relatives.
Produced in response to the successful Bacillus 2000 meeting in Bruges and was supported by the Federation of European Microbiological Societies, the Belgian Society for Microbiology, and several commercial sponsors.
Of use to those working in fields as diverse as medicine, agriculture, food and industry.
Comprehensive and up-to-date analysis of the systematics of these organisms.
Includes the application of sophisticated chemotaxonomic and genetic characterization methods.

This volume provides a comprehensive review of the family, Gentianaceae, covering phylogeny, classification, biogeography, palynology, phytochemistry, and morphology, and also presents the first classification of the entire family to be published for over 100 years, generated using modern molecular- and morphology-based phylogenetic data. The volume places the Gentianaceae in context with its relatives in the order Gentianales and subclass Asteridae; presents an updated, phylogenetic classification of tribes, subtribes, and genera; investigates the corroborative value of morphological features in phylogenetic diagnoses; and comprehensively summarizes palynology, seed morphology, and phytochemistry.

This text can be read at many levels. Not least it is an extraordinary inventory - an illustrated summary of all the Earthly creatures that have ever lived. Whatever living thing you come across, from E-coli to an oak tree or an elephant, this book will show you what kind of creature it is, and how it relates to all others. Yet there are far too many creatures to present merely as a catalogue. The list of species already described is vast enough - nearly two million - but there could in reality be as many as 30 million different animals, plants, fungi and protists - and perhaps another 400 million different bacteria and archaea. In the 4000 million years or so since life first began on Earth, there could have been several thousand billion different species. The only way to keep track of so many is to classify - placing similar creatures into categories, which nest within larger categories, and so on. As the centuries have passed, so it has become clear that the different groups are far more diverse than had ever been appreciated. Thus Linneus in the 18th century placed all living things in just two kingdoms, Animals and Plants.

Scaling relationships are a persistent theme in biology. Examples include branching patterns of blood vessels, structural and functional correlates of body size, distribution of body size and abundance among species, and variations in populations within an area or over time. This book, based on a conference at the Santa Fe Institute, brings together many of the most prominent workers in the area to assess our current understanding of scaling relationships at the physiological, biomechanical, and ecological levels.

Now that scientists can sequences genes with relative ease, the relationships among living organisms are becoming better known. Those relationships are summarized as phylogenetic trees. This book reveals how those trees can be used to give insights into diverse fields of biological enquiry including ecology, epidemiology, development, conservation, and the evolutionary process itself.

Designed to help students make better taxonomic judgments, this case book contains exercises and case studies which describe how to recognize similarities and differences in sets of comparative data. It explains interpretation with reference to the various ranks in the Linnean hierarchy.

In his historical perspective on the changes in scientific thought over the last 100 years, Carl N. Degler explores the study of social evolution and the ongoing search for human nature. In Search of Human Nature provides a detailed perspective on the reasons behind the shifting emphasis in social thought from biology, to culture, and again to biology. Degler examines why these changes took place, the evidence and people fostering these changes and why students of human nature decided to accept this momentous change in thought. He suggests varying ideologies as the underlying force behind this shift in the study of social science. From Darwin's theory that human social behaviour has drastically evolved from animals, to the belief that human experience serves as the basic differentiating factor in humans, Degler provides a thorough and captivating examination of the roots of human behaviour.

Historically, naturalists who propose theories of evolution, including Darwin and Wallace, have done so in order to explain the apparent relationship of natural classification. This book begins by exploring the intimate historical relationship between patterns of classification and patterns of phylogeny. It is a circular argument, however, to use the data for classification and the concept of homology as evidence for evolution, when evolution is the theory explaining the phenomenon of natural classification. Alec Panchen presents other evidence for evolution in the form of a historically-based but rigorously logical argument. This is then followed by a history of methods of classification and phylogeny reconstruction including current mathematical and molecular techniques. The author makes the important claim that if the hierarchical pattern of classification is a real phenomenon, then biology is unique as a science in making taxonomic statements. This conclusion is reached by way of historical reviews of theories of evolutionary mechanism and the philosophy of science as applied to biology.

Western philosophy and religion, James Rachels argues, have been shaken by the implications of Darwin's work, most notably the controversial idea that humans are simply a more complex kind of animal. Here, Rachels assesses a number of studies that suggest how closely humans are linked to other primates in behavior, and then goes on to show how this idea undercuts the work of many prominent philosophers.

Created from Animals offers a provocative look at how Darwinian evolution undermines many tenets of traditional philosophy and religion. Rachels begins by examining Darwin's own life and work, presenting an astonishingly vivid and compressed biography. We see Darwin's studies of the psychological links in evolution (such as emotions in dogs, and the "mental powers" of worms), and how he addressed the moral implications of his work, especially in his concern for the welfare of animals. Rachels goes on to present a lively and accessible survey of the controversies that followed in Darwin's wake, ranging from Herbert Spencer's Social Darwinism to Edward O. Wilson's sociobiology, and discusses how the work of such influential intellects as Descartes, Hume, Kant, T.H. Huxley, Henri Bergson, B.F. Skinner, and Stephen Jay Gould has contributed to--or been overthrown by--evolutionary science.

With this sweeping survey of the arguments, the philosophers, and the deep implications surrounding Darwinism, Rachels lays the foundations for a new view of morality. Virbrantly written and provocatively argued, Created from Animals offers a new perspective on issues ranging from suicide to euthanasia to animal rights.

Human Population Biology is a careful integration of the social and biological sciences, drawing on anthropology, biology, human ecology and medicine to provide a comprehensive understanding of how our species adapts to natural and man-made environments. The book's chapters fall into five parts. In Part I, techniques to adapt and apply large-scale demographic methods to smaller populations, particularly important for studying non-Western populations, are presented. In Part II, the relationship of medical genetics to human adaptability and patterns of disease epidemiology in small, non-Western populations are discussed. In Part III work capacity, climatic stress and nutrition are covered. In Part IV methods for growth assessment and prediction are presented and ageing is addressed. The final section, Part V, presents integrated case studies of human adaptation to high altitude, and patterns of modernization and stress resulting from cultural change.

This is an essential reference for describing, measuring and classifying the foliage of flowering plants. The presented system provides long-needed guidelines for characterizing the organization, shape, venation, and surface features of angiosperm leaves. In contrast to systems focusing on reproductive characters for identification, the emphasis is on macroscopic features of the leaf blade including leaf characters, venation, and tooth characters. The advantage of this system is that it allows for the classification of plants independently of their flowers, which is especially useful for fossil leaves (usually found in isolation) and tropical plants (whose flowering cycles are brief and irregular, and whose fruits and flowers may be difficult to access). An illustrated terminology including detailed definitions and annotated illustrations is the focus of the classification system, the aim of which is to provide a framework with comparative examples to allow both modern and fossil leaves to be described and classified consistently.

This beautifully illustrated glossary constitutes an extraordinary collection of the specialist terms used in many botanical works. The book is arranged in two sections: the glossary, which provides clear definitions for over 2400 of the most commonly used botanical and horticultural terms, and illustrations, which can be cross-referenced to the glossary. The illustrations section comprises over 120 large format pages packed with accurate, well labelled line drawings that complement the definitions. The illustrations are grouped according to specific features, allowing quick comparisons of different forms. This outstanding reference will be welcomed by all readers grappling with botanical terms, whether student, professional, or hobbyist.

Positive psychologists focus on ways that we can advance the lives of individuals and communities by studying the factors that increase positive outcomes such as life satisfaction and happiness. Evolutionary psychologists use the principles of evolution, based on Darwin's understanding of life, to help shed light on any and all kinds of psychological phenomena. This book brings together both fields to explore positive evolutionary psychology: the use of evolutionary psychology principles to help people and communities experience more positive and fulfilling lives. Across eleven chapters, this book describes the basic ideas of both evolutionary and positive psychology, elaborates on the integration of these two fields as a way to help advance the human condition, discusses several domains of human functioning from the perspective of positive evolutionary psychology, and finally, looks with an eye toward the future of work in this emerging and dynamic field. Over the past few decades, evolutionary psychologists have begun to crack the code on such phenomena as happiness, gratitude, resilience, community, and love. This book describes these facets of the human experience in terms of their evolutionary origins and proposes how we might guide people to optimally experience such positive phenomena in their everyday lives.
