A world of categones devmd of spirit waits for life to return. Saul Bellow, Humboldt's Gift The stock-in-trade of communicating hypotheses about the historical path of evolution is a graphical representation called a phylogenetic tree. In most such graphics, pairs of branches diverge from other branches, successively marching across abstract time toward the present. To each branch is tied a tag with a name, a binominal symbol that functions as does the name given to an individual human being. On phylogenetic trees the names symbolize species. What exactly do these names signify? What kind of information is communicated when we claim to have knowledge of the following types? "Tetonius mathewzi was ancestral to Pseudotetonius ambiguus. " "The sample of fossils attributed to Homo habzlis is too variable to contain only one species. " "Interbreeding populations of savanna baboons all belong to Papio anubis. " "Hylobates lar and H. pileatus interbreed in zones of geographic overlap. " While there is nearly universal agreement that the notion of the speczes is fundamental to our understanding of how evolution works, there is a very wide range of opinion on the conceptual content and meaning of such particular statements regarding species. This is because, oddly enough, evolutionary biolo gists are quite far from agreement on what a species is, how it attains this status, and what role it plays in evolution over the long term."
Mites are very small animals, characterized by wingless and eyeless bodies, in which sociality has been discovered. This book offers detailed descriptions of the diverse social systems and the social evolution of mites, ranging from genetic to ecological aspects. Through a broad spectrum of studies including traditional natural history, taxonomy, modern evolutionary and behavioral ecology, and theoretical models as well, the book addresses a number of important findings on plant mite evolution and species radiation, with the author succeeding in combining theoretical and practical approaches in behavioral ecology by proposing a new game theory. These findings reflect the complex evolutionary history of these taxa and also help to point out clearly what is known and what is not yet known to date. Mites have been considered a minor animal group, but the author shows that mites actually possess great diversity and therefore make unique materials for evolutionary and behavioral studies.
Species evolve over time to become perfectly adapted to their environments, right?Well, sometimes. Consider that an elephant will not grow a seventh set of teeth, even though wearing down the sixth will condemn it to starvation; that hosts of the European cuckoo seem unable to tell that the overgrown monster in their nest is not their own chick; and that whales are fully aquatic mammals who, millions of years after first abandoning the land, still cannot breathe underwater. This book is about evolution, but not its greatest hits. Instead, it explores everything in the animal kingdom that is self-defeating, ill-made, uneconomical, or downright weird – and explains how natural selection has favoured it. In the grand struggle for survival, some surprising patterns emerge: animals are always slightly out-of-date; inefficiency tends to increase over time; predators usually lose, and parasites usually win. With equal parts humour and scientific insight, Andy Dobson is here to explain the how and why of evolution’s limits and liabilities.
In order to describe the logic of morality, "contractualist " philosophers have studied how individuals behave when they choose to follow their moral intuitions. These individuals, contractualists note, often act as if they have bargained and thus reached an agreement with others about how to distribute the benefits and burdens of mutual cooperation. Using this observation, such philosophers argue that the purpose of morality is to maximize the benefits of human interaction. The resulting "contract " analogy is both insightful and puzzling. On one hand, it captures the pattern of moral intuitions, thus answering questions about human cooperation: why do humans cooperate? Why should the distribution of benefits be proportionate to each person's contribution? Why should the punishment be proportionate to the crime? Why should the rights be proportionate to the duties? On the other hand, the analogy provides a mere as-if explanation for human cooperation, saying that cooperation is "as if " people have passed a contract-but since they didn't, why should it be so? To evolutionary thinkers, the puzzle of the missing contract is immediately reminiscent of the puzzle of the missing "designer " of life-forms, a puzzle that Darwin's theory of natural selection essentially resolved. Evolutionary and contractualist theory originally intersected at the work of philosophers John Rawls and David Gauthier, who argued that moral judgments are based on a sense of fairness that has been naturally selected. In this book, Nicolas Baumard further explores the theory that morality was originally an adaptation to the biological market of cooperation, an arena in which individuals competed to be selected for cooperative interactions. In this environment, Baumard suggests, the best strategy was to treat others with impartiality and to share the costs and benefits of cooperation in a fair way, so that those who offered less than others were left out of cooperation while those who offered more were exploited by their partners. It is with this evolutionary approach that Baumard ultimately accounts for the specific structure of human morality.
This volume brings together information about recent discoveries and current theories concerning the origin and early evolution of anthropoid primates monkeys, apes, and humans. Although Anthropoidea is one of the most dis tinctive groups of living primates, and the origin of the group is a frequent topic of discussion in the anthropological and paleontological literature, the topic of anthropoid origins has rarely been the foeus of direct discussion in primate evolution. Rather, diseussion of anthropoid origins appears as a ma jor side issue in volumes dealing with the origin of platyrrhines (Ciochon and Chiarelli, 1980), in discussions about the phylogenetic position of Tarsius, in descriptions of early anthropoid fossils, and in descriptions and revisions of various fossil prosimians. As a result, the literature on anthropoid origins has a long history of argument by advocacy, in which scholars with different views have expounded individual theories based on a small bit of evidence at hand, often with little consideration of alternative views and other types of evidence that have been used in their support. This type of scholarship struck us as a relatively unproductive approach to a critical issue in primate evolution."
Evolutionary Aesthetics is the attempt to understand the aesthetic judgement of human beings and their spontaneous distinction between "beauty" and "ugliness" as a biologically adapted ability to make important decisions in life. The hypothesis is - both in the area of "natural beauty" and in sexuality, with regard to landscape preferences, but also in the area of "artificial beauty" (i.e. in art and design) - that beauty opens up fitness opportunities, while ugliness holds fitness risks. In this book, this adaptive view of aesthetics is developed theoretically, presented on the basis of numerous examples, and its consequences for evolutionary anthropology are illuminated.
Presents detailed discussions on the systematic, ecological, and evolutionary implications of the pollination of terrestrial orchids of Southern Australia and the Mediterranean; variation and diversity in deep-sea echinoids; the molecular evolution of the alcohol dehydrogenase genes in Drosophila;

Perspective of This Volume Charles Darwin brought the Galapagos Islands to the attention of zoologists, botanists, and geologists following the six-week visit of H. M. S. Beagle to the islands in 1835. Since then published research on the biota of the islands, partic ularly in multiauthored volumes, has focused on terrestrial plants and animals. The present volume is designed specifically to provide a summary of work on the marine invertebrate fauna. One deviation from that objective was the inclusion of a chapter on land snails, which proved to be a good choice because the phylum Mollusca is now covered more thoroughly in this volume than in any single previous scholarly work on the Galapagos. The academic bottom line with this book is to elucidate the evolutionary responses of shallow water, benthic marine invertebrates to the unique set of insular conditions that exist in the Galapagos Islands. The route taken to that objective has many paths including taxonomic revision, determining biogeo graphic affinities, and examining the ecological requirements of species. The information presented here is for some groups from the islands the first stage in a thorough process that can eventually lead to an understanding of the phylogenetic relationships of these species."
Research in science education is now an international activity. This book asks for the first time, Does this research activity have an identity? -It uses the significant studies of more than 75 researchers in 15 countries to see to what extent they provide evidence for an identity as a distinctive field of research. -It considers trends in the research over time, and looks particularly at what progression in the research entails. -It provides insight into how researchers influence each other and how involvement in research affects the being of the researcher as a person. -It addresses the relation between research and practice in a manner that sees teaching and learning in the science classroom as interdependent with national policies and curriculum traditions about science. It gives graduate students and other early researchers an unusual overview of their research area as a whole. Established researchers will be interested in, and challenged by, the identity the author ascribes to the research and by the plea he makes for the science content itself to be seen as problematic.
Origins of Plastids looks at symbiosis and symbiogenesis as a mechanism of evolution. This theory of endosymbiotic evolution postulates that photosynthetic prokaryotes living as endosymbionts within eukaryotic cells gradually evolved into the organelle structures called chloroplasts. The theory is controversial but has been strongly advocated by Lynn Margulis. Based on a colloquium held at the Bodega Bay Marine Laboratory of the University of California at Davis, Origins of Plastids reviews recent data on this most basic problem in plant evolution. In it, leading researchers in the field apply the theory of endosymbiotic evolution to plastid origins, producing an important new reference work for both professionals and graduates interested in the origins of life, the origins of the eukaryotic cell and its organelles, and the evolution of the higher plants in general. Origins of Plastids represents the state-of-the-art in its field. It should find a place on the bookshelves of people interested in microbiology, plant science, phycology, cell biology, and evolution.
Begging by nestling birds has become the model system for investigating evolutionary conflicts of interest within families and their theoretical resolution provided by honest signals of offspring need. In response to the recent explosions of scientific papers on the revolution of begging; we have brought together twenty-four original contributions from major researchers in all areas of this dynamic field. Organised into six sections: I: Theoretical approaches; II: Begging as a signal; III: Nestling physiology; IV: Sibling competition; V: Brood parasitism; and VI: Statistical approaches; this book is primarily aimed at research scientists and those at the graduate student level. For the first time, the theoretical and empirical literature on begging is fully reviewed. New ideas and data are also presented from a wide range of natural systems, and each chapter ends with suggestions for future study.
This book evaluates the reputation of the coelacanth, presenting up-to-date accounts of the structure of fossil coelacanths, and suggests a family history to show that there have been subtle but significant changes in coelacanth history.
In 1970, Manfred Eigen initiated the study of the origin of self-reproducing systems of macromolecules and their evolution. Large-scale nucleotide sequencing (with computer methods) was introduced from 1977. The authors of this book, the first edition of which appeared (in Russian) in 1985, have been engaged in the research of the evolution of molecular genetic regulatory systems ever since those pioneering years. The book considers many fundamental problems of molecular biology, evolution, molecular genetic organization, the structure and function of macromolecules, always with the underlying motive of developing a unified theory. It describes many original, theoretical results as well as computational methods.
This book develops and tests an ecological and evolutionary theory of the causes of human values the core beliefs that guide people s cognition and behavior and their variation across time and space around the world. We call this theory the parasite-stress theory of values or the parasite-stress theory of sociality. The evidence we present in our book indicates that both a wide span of human affairs and major aspects of human cultural diversity can be understood in light of variable parasite (infectious disease) stress and the range of value systems evoked by variable parasite stress. The same evidence supports the hypothesis that people have psychological adaptations that function to adopt values dependent upon local infectious-disease adversity. The authorshave identified key variables, variation in infectious disease adversity and in the core values it evokes, for understanding these topics and in novel and encompassing ways. Although the human species is the focus in the book, evidence presented in the book shows that the parasite-stress theory of sociality informs other topics in ecology and evolutionary biology such as variable family organization and speciation processes and biological diversity in general in non-human animals."
Professor H James Birx shows how the never-ending controversy of human evolution came to be. He details the events that caused thinkers like Charles Darwin to develop his theory of evolution, and what ideas caused some people to reconcile a somewhat mystical theology with a concrete model of the universe. He tells you how Darwin's work infuriated everybody from "God-fearing" Christians to the church hierarchies. Birx explains how scientific advances and philosophical arguments have made beliefs about divine intervention as the origin of man a moot point. He shows how creationism ignores proven scientific facts, and how human evolution remains a much sounder truth. You will read how some western religions are starting to accept evolution as the process which creates life on earth. You will also learn why scientific evolution and creationism have not been accepted together and how bold attempts to merge the two ideas have failed miserably.
Foreword by Phillip V. Tobias The introduction of rhesus macaques to Cayo Santiago, Puerto Rico in 1938, and the subsequent development of the CPRC for biomedical research, continues its long history of stimulating studies in physical anthropology. The CPRC monkey colonies, and the precise demographic data on the derived skeletal collection in the Center's Laboratory of Primate Morphology and Genetics (LPMG), provide rare opportunities for morphological, developmental, functional, genetic, and behavioral studies across the life span of rhesus macaques as a species, and as a primate model for humans. The book grows out of a symposium Wang is organizing for the 78th annual meeting of the American Association of Physical Anthropologists to be held in April 2009. This symposium will highlight recent and ongoing research in, or related to, physical anthropology, and reveal the numerous research opportunities that still exist at this unusual rhesus facility. Following an initial historical review of CPRC and its research activities, this book will emphasize recent and current researches on growth, function, genetics, pathology, aging, and behavior, and the impact of these researches on our understanding of rhesus and human morphology, development, genetics, and behavior. Fourteen researchers will present recent and current studies on morphology, genetics, and behavior, with relevance to primate and human growth, health, and evolution. The book will include not only papers presented in the symposium, but also papers from individuals who could not present their work at the meeting due to limitations in the maximum number (14) of permitted speakers.
The papers in this volume are representative of those presented at a conference entitled "Creatures of the Dark: The Nocturnal Prosimians," held at Duke University, June 9-12, 1993. The purpose of the conference, attended by more than 100 scientists, was to assemble, for the ftrst time ever, scholars from diverse ftelds with a common interest in the nocturnal prosimian primates. The history of the precursors of this meeting are outlined in the Historical Perspective by Doyle (this volume). Most of the invited papers are presented here in modified form, as are several papers originally presented as posters. Two papers are included that were not presented, due to scheduling conftcts and health considerations. Some papers, delivered from the podium, are not included in this volume. Interactions among conference participants resulted in many revisions to the contributions, as did the comments of reviewers and the editors. Several papers which contained new data or new interpretations of familiar phenomena met with constructive criticism, resulting in modification of the original papers. We thank all of the contributors for their patience and cooperation, and commend the numerous reviewers who generously donated their time and expertise. We greatly appreciate funding from the National Institutes of Health, the Wenner Gren Foundation for Anthropological Research, the Duke University Center for International Studies, the Duke University Primate Center, and Drs. Charles Putman of Duke University and Malcolm Gillis, currently of Rice Universtiy.
Contributors to this volume offer new research on extinction processes in birds, nest predation, and song systems, and describes a graphical model that helps predict the reproductive consequences of time allocation between the competing demands of guarding young birds and foraging for food. Current Ornithology is the only English-language publication currently devoted exclusively to extensive reviews and synthesis of topics pertaining to all aspects of the biology of birds. Chapters fall under such diverse rubrics as ecology, evolution, behavior, phylogeny, behavioral ecology, anatomy and physiology, and conservation biology. All authors are leading authorities on their subjects, and each chapter is refereed by experts in the topics covered. Although all chapters focus primarily on birds, some topics, such as the social cognition of birds as compared to primates (Volume 13), have significant application to disciplines outside of ornithology. Current Ornithology aims to provide an accessible, up-to-date, accurate source of data and to contribute to conceptual generalization and unification across the biological sciences.
More than two hundred years ago, Dr. William Paley wrote a series of books that marshaled evidence for the Christian faith. His books were often required reading at major institutions of learning. Believers and unbelievers alike wrestled with Paley's arguments and his compelling presentation of them. Paley's Natural Theology was one of those books. In it, he showed from biology and human anatomy that the argument for design was a clear and self-evident inference from the facts, and from that point of departure proposed that only a designer God could adequately account for those facts. His famous analogy from an intricate watch to the required deduction that there exists a watchmaker persists to this day. When evolutionary theory rose to dominance, it was thought that Paley's views on 'intelligent design' had been fully put to rest. However, each new generation discovers anew that evolutionary theory requires them to accept as true what appears, on its face, to be patently absurd: that immense complexity, surpassing in its apparent genius what 1,000 human geniuses cannot create was nonetheless the product of unguided, intrinsically dumb, natural forces. Unsatisfied, they consider the alternatives. The argument is sure to rage for another two hundred years and Dr. Paley's Natural Theology will prove to be relevant then as it is relevant today, advances in our understanding of biology notwithstanding, and, actually, because of those very same advances. "I do not think I hardly ever admired a book more than Paley's Natural Theology: I could almost formerly have said it by heart." Charles Darwin, 1859.
Synthesizing the findings from a wide range of disciplines - from biology and anthropology to philosophy and linguistics - the emerging field of Biosemiotics explores the highly complex phenomenon of sign processing in living systems. Seeking to advance a naturalistic understanding of the evolution and development of sign-dependent life processes, contemporary biosemiotic theory offers important new conceptual tools for the scientific understanding of mind and meaning, for the development of artificial intelligence, and for the ongoing research into the rich diversity of non-verbal human, animal and biological communication processes. Donald Favareau's Essential Readings in Biosemiotics has been designed as a single-source overview of the major works informing this new interdiscipline, and provides scholarly historical and analytical commentary on each of the texts presented. The first of its kind, this book constitutes a valuable resource to both bioscientists and to semioticians interested in this emerging new discipline, and can function as a primary textbook for students in biosemiotics, as well. Moreover, because of its inherently interdisciplinary nature and its focus on the 'big questions' of cognition, meaning and evolutionary biology, this volume should be of interest to anyone working in the fields of cognitive science, theoretical biology, philosophy of mind, evolutionary psychology, communication studies or the history and philosophy of science.
Entomology as a science of inter-depended branches like molecular entomology, insect biotechnology, has made rapid progress. This also implies that there is an urgent need to manage the available resources. In the past five decades, entomology has taken giant steps ahead. The aim of this work is to integrate perspectives across molecular and biochemistry, physiology, reproduction, developmental biology, molecular evolution, genetics and RNAi applications. This century is proclaimed as the Era of Biotechnology and it consists of all types of Mol-Bio-Gen applications, which is an essential component for a thorough understanding of the insect biology. The aim of this work is to provide the comprehensive review of recent research from various geographic areas around the world and contributing authors that are recognized experts in their respective field of Genomic entomology. This Volume emphasizes upon the need for and relevance of studying molecular aspects of entomology in Universities, Agricultural Universities and other centers of molecular research. It will also serve as a landmark source for Insect advance science technology.
During the last ZO years great progress has been achieved in our understanding of both earth history and vertebrate evolution. The result is that climatic/tectonic events in earth history can now be placed in a more precise and global time frame, that permit their evaluation as abiotic causal factors which might trigger extinction and dispersal events in vertebrate history. Great strides have also been made in genetics and cell biology, providing new insight into phylogenetic relationships among many vertebrates. These new data, along with data on chronologie resolution of earth history, provide tests of previous interpretations regarding ancestral-descendant relationships based solely on the fossil record. It is fitting and proper that a volume on European Neogene mammal chronology is produced at this time, to ensure that new interpretations of vertebrate evolution and chronology are based on the most accurate and current data. Vertebrate paleon tologists believe that the fossil record is the only secure data for measuring the actual course and tempo of vertebrate evolution. Knowledge of the fossil record must keep pace with advances in other areas of science so that inferences on vertebrate evolu tion are accurate and meaningful."
Polyploidy - whole-genome duplication (WGD) - is a fundamental driver of biodiversity with significant consequences for genome structure, organization, and evolution. Once considered a speciation process common only in plants, polyploidy is now recognized to have played a major role in the structure, gene content, and evolution of most eukaryotic genomes. In fact, the diversity of eukaryotes seems closely tied to multiple WGDs. Polyploidy generates new genomic interactions - initially resulting in "genomic and transcriptomic shock" - that must be resolved in a new polyploid lineage. This process essentially acts as a "reset" button, resulting in genomic changes that may ultimately promote adaptive speciation. This book brings together for the first time the conceptual and theoretical underpinnings of polyploid genome evolution with syntheses of the patterns and processes of genome evolution in diverse polyploid groups. Because polyploidy is most common and best studied in plants, the book emphasizes plant models, but recent studies of vertebrates and fungi are providing fresh perspectives on factors that allow polyploid speciation and shape polyploid genomes. The emerging paradigm is that polyploidy - through alterations in genome structure and gene regulation - generates genetic and phenotypic novelty that manifests itself at the chromosomal, physiological, and organismal levels, with long-term ecological and evolutionary consequences. |
