As an introduction to the present book I would like to explain how it was, that I, a commercial nurseryman, became so keenly interested in Conifers and their nomen clature. In August 1924 the Dutch Dendrological Society was founded and at the same time a Committee for Nomenclature of woody plants was set up and I served on this committee as one of the members. Our first activity was to bring the catalogues of the various leading nurserymen in the Netherlands into line with the International Rules of Botanical Nomenclature and also to check their nursery stock. Formerly these catalogues had shown a rather confused nomenclature, nurserymen having usually made use of a variety of inconsistent books as guides in compiling their catalogues. In the course of the work a close co-operation between scientific and practical workers developed. Although I had also fully contributed to the correct naming of hardy shrubs and perennials, 1 was most interested in Conifers. I had tried out several species, had grown a wide choice of garden forms and selected types of particular merit for propagation. My special love for Conifers lead to the publication of my Name-list of Conifers (1937), which was adopted as a standard for varietal names at the International Horticultural Congress in Berlin (1938). Later I prepared my book 'Coniferen, Ephedra en Ginkgo' in the Dutch language (1949); compiling the Conifers cultivated or known to be grown in the Netherlands and Belgium at that time."

DNA Barcoding has been promoted since 2003 as a new, fast, digital genomics-based means of identifying natural species based on the idea that a small standard fragment of any organism s genome (a so-called micro-genome ) can faithfully identify and help to classify every species on the planet. The fear that species are becoming extinct before they have ever been known fuels barcoders, and the speed, scope, economy and user-friendliness claimed for DNA barcoding, as part of the larger ferment around the genomics revolution, has also encouraged promises that it could inspire humanity to reverse its biodiversity-destructive habits.

This book is based on six years of ethnographic research on changing practices in the identification and classification of natural species. Informed both by Science and Technology Studies (STS) and the anthropology of science, the authors analyse DNA barcoding in the context of a sense of crisis concerning global biodiversity loss, but also the felt inadequacy of taxonomic science to address such loss. The authors chart the specific changes that this innovation is propelling in the collecting, organizing, analyzing, and archiving of biological specimens and biodiversity data. As they do so they highlight the many questions, ambiguities and contradictions that accompany the quest to create a genomics-based environmental technoscience dedicated to biodiversity protection. They ask what it might mean to recognise ambiguity, contradiction, and excess more publicly as a constitutive part of this and other genomic technosciences.

"Barcoding Nature" will be of interest to students and scholars of sociology of science, science and technology studies, politics of the environment, genomics and post-genomics, philosophy and history of biology, and the anthropology of science."

Historical biogeography-the study of the history of species through both time and place-first convinced Charles Darwin of evolution. This field was so important to Darwin's initial theories and line of thinking that he said as much in the very first paragraph of On the Origin of Species (1859) and later in his autobiography. His methods included collecting mammalian fossils in South America clearly related to living forms, tracing the geographical distributions of living species across South America, and sampling peculiar fauna of the geologically young Galapagos Archipelago that showed evident affinities to South American forms. Over the years, Darwin collected other evidence in support of evolution, but his historical biogeographical arguments remained paramount, so much so that he devotes three full chapters to this topic in On the Origin of Species. Discussions of Darwin's landmark book too often give scant attention to this wealth of evidence, and we still do not fully appreciate its significance in Darwin's thinking. In Origins of Darwin's Evolution, J. David Archibald explores this lapse, showing how Darwin first came to the conclusion that, instead of various centers of creation, species had evolved in different regions throughout the world. He also shows that Darwin's other early passion-geology-proved a more elusive corroboration of evolution. On the Origin of Species has only one chapter dedicated to the rock and fossil record, as it then appeared too incomplete for Darwin's evidentiary standards. Carefully retracing Darwin's gathering of evidence and the evolution of his thinking, Origins of Darwin's Evolution achieves a new understanding of how Darwin crafted his transformative theory.

This 2-volume set is written by the grandfather of Charles Darwin. The purpose of the books is to reduce the facts belonging to animal life into classes, orders, genera, and species; and, by comparing them with each other, to unravel the theory of diseases.

An engaging history of the surprising, poignant, and occasionally scandalous stories behind scientific names and their cultural significance, "More fun than you've ever had with taxonomy in your whole entire life!" (Diana Gabaldon, author of the Outlander series and PhD in Quantitative Behavioral Ecology) Ever since Carl Linnaeus's binomial system of scientific names was adopted in the eighteenth century, scientists have been eponymously naming organisms in ways that both honor and vilify their namesakes. This charming, informative, and accessible history examines the fascinating stories behind taxonomic nomenclature, from Linnaeus himself naming a small and unpleasant weed after a rival botanist to the recent influx of scientific names based on pop-culture icons-including David Bowie's spider, Frank Zappa's jellyfish, and Beyonce's fly. Exploring the naming process as an opportunity for scientists to express themselves in creative ways, Stephen B. Heard's fresh approach shows how scientific names function as a window into both the passions and foibles of the scientific community and as a more general indicator of the ways in which humans relate to, and impose order on, the natural world.

How do radically new kinds of organisms evolve? The Origin of Higher Taxa addresses this essential question, specifically whether the emergence of higher taxa such as orders, classes, and phyla are the result of normal Darwinian evolution acting over a sufficiently long period of time, or whether unusual genetic events and particular environmental and ecological circumstances are also involved. Until very recently, the combination of an incomplete fossil record and a limited understanding about how raw mutations lead via modified ontogenic processes to significant phenotypic changes, effectively stymied scientific debate. However, it is now timely to revisit the question in the light of the discovery of considerable new fossil material (and new techniques for studying it), together with significant advances in our understanding of phenotypic development at the molecular level. This novel text incorporates evidence from morphology, palaeobiology, developmental biology, and ecology, to review those parts of the fossil record that illustrate something of the pattern of acquisition of derived characters in lineages leading to actual higher taxa as well as the environmental conditions under which they occurred. The author's original ideas are set within the context of a broad and balanced review of the latest research in the field. The result is a book which provides a concise, authoritative, and accessible overview of this fascinating subject for both students and researchers in evolutionary biology and palaeontology.

Have humans always waged war? Is warring an ancient evolutionary adaptation or a relatively recent behavior-and what does that tell us about human nature? In War, Peace, and Human Nature, editor Douglas P. Fry brings together leading experts in such fields as evolutionary biology, archaeology, anthropology, and primatology to answer fundamental questions about peace, conflict, and human nature in an evolutionary context. The chapters in this book demonstrate that humans clearly have the capacity to make war, but since war is absent in some cultures, it cannot be viewed as a human universal. And counter to frequent presumption the actual archaeological record reveals the recent emergence of war. It does not typify the ancestral type of human society, the nomadic forager band, and contrary to widespread assumptions, there is little support for the idea that war is ancient or an evolved adaptation. Views of human nature as inherently warlike stem not from the facts but from cultural views embedded in Western thinking. Drawing upon evolutionary and ecological models; the archaeological record of the origins of war; nomadic forager societies past and present; the value and limitations of primate analogies; and the evolution of agonism, including restraint; the chapters in this interdisciplinary volume refute many popular generalizations and effectively bring scientific objectivity to the culturally and historically controversial subjects of war, peace, and human nature.

Animal Evolution provides a comprehensive analysis of the evolutionary interrelationships and myriad diversity of the Animal Kingdom. It reviews the classical, morphological information from structure and embryology, as well as the new data gained from studies using immune stainings of nerves and muscles and blastomere markings which makes it possible to follow the fate of single blastomeres all the way to early organogenesis. Until recently, the information from analyses of gene sequences has tended to produce myriads of quite diverging trees. However, the latest generation of molecular methods, using many genes, expressed sequence tags, and even whole genomes, has brought a new stability to the field. For the first time this book brings together the information from these varied fields, and demonstrates that it is indeed now possible to build a phylogenetic tree from a combination of both morphology and gene sequences. This thoroughly revised third edition of Animal Evolution brings the subject fully up to date, especially in light of the latest advances in molecular techniques. The book is generously illustrated throughout with finely detailed line drawings and clear diagrams, many of them new.

Animal life, now and over the past half billion years, is incredibly diverse. Describing and understanding the evolution of this diversity of body plans - from vertebrates such as humans and fish to the numerous invertebrate groups including sponges, insects, molluscs, and the many groups of worms - is a major goal of evolutionary biology. In this book, a group of leading researchers adopt a modern, integrated approach to describe how current molecular genetic techniques and disciplines as diverse as palaeontology, embryology, and genomics have been combined, resulting in a dramatic renaissance in the study of animal evolution.
The last decade has seen growing interest in evolutionary biology fuelled by a wealth of data from molecular biology. Modern phylogenies integrating evidence from molecules, embryological data, and morphology of living and fossil taxa provide a wide consensus of the major branching patterns of the tree of life; moreover, the links between phenotype and genotype are increasingly well understood. This has resulted in a reliable tree of relationships that has been widely accepted and has spawned numerous new and exciting questions that require a reassessment of the origins and radiation of animal life. The focus of this volume is at the level of major animal groups, the morphological innovations that define them, and the mechanisms of change to their embryology that have resulted in their evolution. Current research themes and future prospects are highlighted including phylogeny reconstruction, comparative developmental biology, the value of different sources of data and the importance of fossils, homology assessment, character evolution, phylogeny of major groups of animals, and genome evolution. These topics are integrated in the light of a 'new animal phylogeny', to provide fresh insights into the patterns and processes of animal evolution.
Animal Evolution provides a timely and comprehensive statement of progress in the field for academic researchers requiring an authoritative, balanced and up-to-date overview of the topic. It is also intended for both upper level undergraduate and graduate students taking courses in animal evolution, molecular phylogenetics, evo-devo, comparative genomics and associated disciplines.

Animal phylogeny is undergoing a major revolution due to the availability of an exponentially increasing amount of molecular data and the application of novel methods of phylogentic reconstruction, as well as the many spectacular advances in palaeontology and molecular developmental biology. Traditional views of the relationships among major phyla have been shaken and new, often unexpected, relationships are now being considered. At the same tiem, the emerging discipline of evolutionary developmental biology, or 'evo-devo', has offered new insights into the origin and evolvability of major traits of animal architecture and life cycle. All these developments call for a revised interpretation of the pathways along which animal structure and development has evolved since the origin of the Metazoa.
Perspectives in Animal Phylogeny and Evolution takes on this challenge, successfully integrating morphological, fossil and molecular evidence to produce a novel reinterpretation of animal evolution. Central to the book's approach is an 'evo-devo' perspective on animal evolution (with all the fresh insights this has given into the origin of animal organization and life cycles), complementary to the more traditional perspectives of pattern (cladistics, comparative anatomy and embryology), mechanisms (developmental biology) and adaptation (evolutionary biology). The author advocates the need to approach the study of animal evolution with a critical attitude towards many key concepts of comparative morphology and developmental biology. Particular attention in the book is paid to the evolution of life cycles and larval forms.
This accessible text is suitable for graduate students takingadvanced courses in evolutionary developmental biology, invertebrate zoology, molecular phylogenetics and palaeontology, as well as professional researchers in these fields requiring an authoritative and up-to-date overview of this dynamic topic.

Even before the publication of Darwin's Origin of Species, the perception of evolutionary change has been a tree-like pattern of diversification - with divergent branches spreading further and further from the trunk. In the only illustration of Darwin's treatise, branches large and small never reconnect. However, it is now evident that this view does not adequately encompass the richness of evolutionary pattern and process. Instead, the evolution of species from microbes to mammals builds like a web that crosses and re-crosses through genetic exchange, even as it grows outward from a point of origin. Some of the avenues for genetic exchange, for example introgression through sexual recombination versus lateral gene transfer mediated by transposable elements, are based on definably different molecular mechanisms. However, even such widely different genetic processes may result in similar effects on adaptations (either new or transferred), genome evolution, population genetics, and the evolutionary/ecological trajectory of organisms. For example, the evolution of novel adaptations (resulting from lateral gene transfer) leading to the flea-borne, deadly, causative agent of plague from a rarely-fatal, orally-transmitted, bacterial species is quite similar to the adaptations accrued from natural hybridization between annual sunflower species resulting in the formation of several new species. Thus, more and more data indicate that evolution has resulted in lineages consisting of mosaics of genes derived from different ancestors. It is therefore becoming increasingly clear that the tree is an inadequate metaphor of evolutionary change. In this book, Arnold promotes the 'web-of-life' metaphoras a more appropriate representation of evolutionary change in all lifeforms.

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.

Ancestral sequence reconstruction is a technique of growing importance in molecular evolutionary biology and comparative genomics. As a powerful tool for testing evolutionary and ecological hypotheses, as well as uncovering the link between sequence and molecular phenotype, there are potential applications in a range of fields. Ancestral Sequence Reconstruction starts with a historical overview of the field, before discussing the potential applications in drug discovery and the pharmaceutical industry. This is followed by a section on computational methodology, which provides a detailed discussion of the available methods for reconstructing ancestral sequences (including their advantages, disadvantages, and potential pitfalls). Purely computational applications of the technique are then covered, including whole proteome reconstruction. Further chapters provide a detailed discussion on taking computationally reconstructed sequences and synthesizing them in the laboratory. The book concludes with a description of the scientific questions where experimental ancestral sequence reconstruction has been utilized to provide insights and inform future research. This research level text provides a first synthesis of the theories, methodologies and applications associated with ancestral sequence recognition, while simultaneously addressing many of the hot topics in the field. It will be of interest and use to both graduate students and researchers in the fields of molecular biology, molecular evolution, and evolutionary bioinformatics.

The protein molecule is the basic building block of every living entity. Its deficiency leads to restricted growth and development of individuals. Globally, such malnutrition is on the rise due to various reasons such as rapid population growth, stagnation of productivity, and ever-rising costs. Millions of people, especially in developing and under-developed countries, suffer from protein malnutrition and the only possible solution is to encourage farmers to grow high-protein food legume crops in their fields for domestic consumption. This, however, could be possible if farmers are provided with new cultivars with high yield, and resistance to major insects, diseases, and key abiotic stresses. The major food legume crops are chickpea, cowpea, common bean, groundnut, lentil, pigeonpea, and soybean. Predominantly, the legume crops are grown under a subsistence level and, therefore, in comparison to cereals and horticultural crops their productivity is low and highly variable. The crop breeders around the globe are engaged in breeding suitable cultivars for harsh and changing environments but success has been limited and not up to needs. With the recent development of new technologies in plant sciences, efforts are being made to help under-privileged farmers through breeding new cultivars which will produce more protein per unit of land area. In this book, the contributors analyze the constraints, review new technologies, and propose a future course of crop breeding programs in seven cold and warm season legume crops.

In On the Origin of Species (1859), Charles Darwin presented his evidence for evolution and natural selection as its mechanism. He drew upon his earliest data gathered during his voyage on the HMS Beagle, which included collecting mammalian fossils in South America clearly related to living forms, tracing the geographical distributions of living species across South America, and sampling the peculiar fauna of the geologically young Galapagos Archipelago that showed evident affinities to South American forms. By the end of the voyage, he came to the realization that instead of various centers of creation, species evolved in different regions throughout the world. However, except for some personal ponderings, he did not express this revelation explicitly in his notebooks until shortly after his return. Over the years, he collected more evidence supporting evolution, but his early work remained paramount: it became the first paragraph of On the Origin of Species and encompassed three separate chapters, as well as later appearing in his autobiography. Many discussions of Darwin's landmark book give scant attention to this wealth of evidence and today we still do not fully appreciate its significance in Darwin's thinking. In Origins of Darwin's Evolution, J. David Archibald explores this lapse. He also shows that Darwin's other early passion, geology, proved a more elusive corroboration of evolution. On the Origin of Species dedicated only one chapter to the rock and fossil record, as it appeared too incomplete for Darwin's evidentiary standards. Carefully retracing Darwin's gathering of evidence and the evolution of his thinking, Origins of Darwin's Evolution achieves a new understanding of how Darwin crafted his transformative theory.

This edited volume is provides an authoritative synthesis of knowledge about the history of life. All the major groups of organisms are treated, by the leading workers in their fields. With sections on: The Importance of Knowing the Tree of Life; The Origin and Radiation of Life on Earth; The Relationships of Green Plants; The Relationships of Fungi; and The Relationships of Animals. This book should prove indispensable for evolutionary biologists, taxonomists, ecologists interested in biodiversity, and as a baseline sourcebook for organismic biologists, botanists, and microbiologists. An essential reference in this fundamental area.

Over-two thirds of the U.S. population is allergic to poison oak, poison ivy, or a related plant. These and many other common plants in our homes, fields, and gardens are irritants that cause misery to many. But surprisingly, there has never been a general guide to help raise awareness of them--and to help avoid them. This new book reviews the history, occurrence, classification, toxicity, and health aspects of all the major allergenic and irritant species.

Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

This volume describes and illustrates the microscopic anatomy of the "aroids", the large, economically important plant family Araceae, and also the basal monocot family Acoraceae.

This fully updated edition explores conceptual as well as technical guidelines for plant taxonomists and geneticists, such as the increasing use of next-generation sequencing (NGS) technologies for numerous applications in plant taxonomy. The volume provides molecular approaches to be used within an "integrative taxonomy" framework, combining a range of nucleic acid and cytogenetic data together with other crucial information (taxonomy, morphology, anatomy, ecology, reproductive biology, biogeography, paleobotany, etc.), which will help not only to best circumvent species delimitation but also to resolve the evolutionary processes in play. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Molecular Plant Taxonomy: Methods and Protocols, Second Edition is an ideal guide for researchers seeking a better understanding of evolutionary processes, at species and population level, through molecular techniques.

Phylogenetic reconstruction--the method by which biologists examine the relationship between living and extinct organisms in an effort to identify evolutionary pathways--has seen radical changes in the last ten years. But as rapid advances in mathematical, molecular, developmental, and cladistic techniques have greatly improved reconstruction efforts, they have also sparked controversy, especially with regard to the assumptions and data underlying the cladistic method. This book brings together contributions from a wide range of practitioners in order to find common ground. By examining numerous models from a variety of fields, the book serves as a guide to the latest methods of classification and phylogeny reconstruction and provides insights into the relative merits that each approach has to offer. In particular, developmental studies emerge as a significant factor in cladogram construction. Splendidly written and wide-ranging in scope, Models in Phylogeny Reconstruction will be welcomed by students and researchers in systematic and evolutionary biology.

Starting with concise species accounts for all the marmoset and tamarin monkeys, this important new book then goes on to review their geographical distributions and still-contested taxonomy, along with comparative reviews of vocalizations, scent-marking, mating systems, infant care and development, social organization, and behaviour and ecology in the wild. As several of these small primates are rare or threatened, these subjects are strongly relevant to their management in captivity as well as for understanding natural populations. This is the first volume for several years to review current knowledge of this family, which comprises 52 species and subspecies found from Panama to northeastern Paraguay to southern Brazil.
