This volume summarizes recent advances in our understanding of the mechanisms that produce successful symbiotic partnerships involving microorganisms. It begins with a basic introduction to the nature of and mechanistic benefits derived from symbiotic associations. Taking that background knowledge as the starting point, the next sections include chapters that examine representative examples of coevolutionary associations that have developed between species of microbes, as well as associations between microbes and plants. The authors conclude with a section covering a broad range of associations between microbes and invertebrate animals, in which they discuss the spectrum of hosts, with examples ranging from bryozoans and corals to nematodes, arthropods, and cephalopods.

This volume integrates the latest findings on earliest life forms, identified and characterised in some of the oldest rocks on Earth. New material from prominent researchers in the field is presented and evaluated in the context of previous work. Emphasis is placed on the integration of analytical methods with observational techniques and experimental simulations. The opening section focuses on submarine hot springs that the majority of researchers postulates served as the cradle of life on Earth. In subsequent sections, evidence for life in strongly metamorphosed rocks such as those in Greenland is evaluated and early ecosystems identified in the well preserved Barberton and Pilbara successions in Southern Africa and Western Australia. The final section includes a number of contributions from authors with alternate perspectives on the evidence and record of early life on Earth. Audience This volume will be valuable to researchers and graduate students in biogeosciences, geochemistry, paleontology and geology interested in the origin of life on earth.

Arguing that human evolution has come to a stand-still, this book sets out to explore the evolutionary steps that have defined life on this planet. It describes the stages from cosmic to chemical and biological evolution and to the development of civilization and culture. From this scientific approach, the author concludes that new rules of ethics are required in order to maintain and improve the civilization and culture of humanity. Matare argues for corrective genetic interference and explores the moral implications.

Landman Division of Paleontology American Museum of Natural History New York, New York 10024 landman@amnh. org When Nautilus: Biology and Paleobiology of a Living Fossil was published in 1987, it marked a milestone in cross-disciplinary collaboration. More than half of the contributing authors (36/65) were paleontologists, many of whom were collaborating with neontological counterparts. Their interest in studying this reclusive, poorly known animal was being driven by a search for clues to the mode of life and natural history of the once dominant shelled cephalopods, through study of the sole surviving genus. At the same time, Nautilus offered an opportunity for neontologists to look at a fundamentally different, phylogenetically basal member of the extant Cephalopoda. It was a w- win situation, combining paleontological deep-time perspectives, old fashioned expeditionary zeal, traditional biological approaches and new techniques. The results were cross-fertilized investigations in such disparate fields as ecology, functional morphology, taphonomy, genetics, phylogeny, locomotive dynamics, etc. As one reviewer of the xxxvi Introduction xxxvii book noted, Nautilus had gone from being one of the least known to one of the best understood of living cephalopods.

Together with early theoretical work in population genetics, the debate on sources of genetic makeup initiated by proponents of the neutral theory made a solid contribution to the spectacular growth in statistical methodologies for molecular evolution. Evolutionary Genomics: Statistical and Computational Methods is intended to bring together the more recent developments in the statistical methodology and the challenges that followed as a result of rapidly improving sequencing technologies. Presented by top scientists from a variety of disciplines, the collection includes a wide spectrum of articles encompassing theoretical works and hands-on tutorials, as well as many reviews with key biological insight. Volume 2 begins with phylogenomics and continues with in-depth coverage of natural selection, recombination, and genomic innovation. The remaining chapters treat topics of more recent interest, including population genomics, -omics studies, and computational issues related to the handling of large-scale genomic data. Written in the highly successful Methods in Molecular Biology (TM) series format, this work provides the kind of advice on methodology and implementation that is crucial for getting ahead in genomic data analyses. Comprehensive and cutting-edge, Evolutionary Genomics: Statistical and Computational Methods is a treasure chest of state-of the-art methods to study genomic and omics data, certain to inspire both young and experienced readers to join the interdisciplinary field of evolutionary genomics.

Darwin takes a look at the life of this incredible man, from his birth, his ground-breaking publications and far-flung travels, Darwinism and his theories on evolution, all the way to his final days. Over 160 stunning images and illustrations are included within Darwin, ranging from personal diary entries (such as those he made when deciding whether to marry or not), letters and handwritten notes, as well as sketches from Darwin's famous works. Revealing the famous scientist's life in compelling detail, Darwin covers not only his scientific career and On the Origin of Species but his personal struggles also, allowing us to see what truly made the man.

This rhetorical study of the various language strategies and competing worldviews involved in the 140-year argument between Biblical creationists and Darwinian evolutionists focuses on the 1860 Huxley/Wilberforce debate, the 1925 Scopes Monkey Trial, and the 1981 Arkansas Creation-Science Trial. When Darwin published his Origins of Species in 1859, he initiated a debate about the origin of human life and the role of God in human affairs scarcely equalled in world history. Smout traces the response of Biblical creationists to Darwinian evolutionists. Looking carefully at the stories told and the tactics used by both sides, he analyzes all available accounts of the original debate culminating in the 1860 Huxley/Wilberforce debate, the 1925 Scopes Monkey Trial, and the 1981 Arkansas Creation-Science Trial. Professor Smout argues that both sides in the controversy use various language strategies to persuade the culture as a whole to see the world that they see and to enact their position as public policy. As Smout illustrates, the problem is that both sides rely on an inadequate conception of language as a namer of timeless realities rather than as an instrument used by human communities to achieve their goals. He attempts to articulate a better view of language and to show how it might help solve intractable arguments such as this. He argues that we should see language as a tool that shapes what we see, and definitions of terms as political acts rather than statements of fact made by disciplinary experts. An important analysis for students and scholars in rhetoric, history, religion, and sociology.

Evolutionary biomechanics is the study of evolution through the analysis of biomechanical systems. Its unique advantage is the precision with which physical constraints and performance can be predicted from first principles. Instead of reviewing the entire breadth of the biomechanical literature, a few key examples are explored in depth as vehicles for discussing fundamental concepts, analytical techniques, and evolutionary theory. Each chapter develops a conceptual theme, developing the underlying theory and techniques required for analyses in evolutionary biomechanics. Examples from terrestrial biomechanics, metabolic scaling, and bird flight are used to analyse how physics constrains the design space that natural selection is free to explore, and how adaptive evolution finds solutions to the trade-offs between multiple complex conflicting performance objectives. Evolutionary Biomechanics is suitable for graduate level students and professional researchers in the fields of biomechanics, physiology, evolutionary biology and palaeontology. It will also be of relevance and use to researchers in the physical sciences and engineering.

Is it accurate to label Darwin's theory "the theory of evolution by natural selection," given that the concept of common ancestry is at least as central to Darwin's theory? Did Darwin reject the idea that group selection causes characteristics to evolve that are good for the group though bad for the individual? How does Darwin's discussion of God in The Origin of Species square with the common view that he is the champion of methodological naturalism? These are just some of the intriguing questions raised in this volume of interconnected philosophical essays on Darwin. The author's approach is informed by modern issues in evolutionary biology, but is sensitive to the ways in which Darwin's outlook differed from that of many biologists today. The main topics that are the focus of the book-common ancestry, group selection, sex ratio, and naturalism-have rarely been discussed in their connection with Darwin in such penetrating detail. Author Professor Sober is the 2008 winner of the Prometheus Prize. This biennial award, established in 2006 through the American Philosophical Association, is designed "to honor a distinguished philosopher in recognition of his or her lifetime contribution to expanding the frontiers of research in philosophy and science." This insightful collection of essays will be of interest to philosophers, biologists, and laypersons seeking a deeper understanding of one of the most influential scientific theories ever propounded.

Scholars have long studied the impact of Charles Darwin's writings on nineteenth-century culture. However, few have ventured to examine the precursors to the ideas of Darwin and others in the Romantic period. Marking Time, edited by Joel Faflak, analyses prevailing notions of evolution by tracing its origins to the literary, scientific, and philosophical discourses of the long nineteenth century. The volume's contributors revisit key developments in the history of evolution prior to The Origin of Species and explore British and European Romanticism's negotiation between the classic idea of a great immutable chain of being and modern notions of historical change. Marking Time reveals how Romantic and post-Romantic configurations of historical, socio-cultural, scientific, and philosophical transformation continue to exert a profound influence on critical and cultural thought.

What happens when we let robots play the game of life? The challenge of studying evolution is that the history of life is buried in the past- we can't witness the dramatic events that shaped the adaptations we see today. But biorobotics expert John Long has found an ingenious way to overcome this problem: he creates robots that look and behave like extinct animals, subjects them to evolutionary pressures, lets them compete for mates and resources, and mutates their &lsquogenes'. In short, he lets robots play the game of life. In Darwin's Devices , Long tells the story of these evolving biorobots- how they came to be, and what they can teach us about the biology of living and extinct species. Evolving biorobots can replicate creatures that disappeared from the earth long ago, showing us in real time what happens in the face of unexpected environmental challenges. Biomechanically correct models of backbones functioning as part of an autonomous robot, for example, can help us understand why the first vertebrates evolved them. But the most impressive feature of these robots, as Long shows, is their ability to illustrate the power of evolution to solve difficult technological challenges autonomously- without human input regarding what a workable solution might be. Even a simple robot can create complex behaviour, often learning or evolving greater intelligence than humans could possibly program. This remarkable idea could forever alter the face of engineering, design, and even warfare. An amazing tour through the workings of a fertile mind, Darwin's Devices will make you rethink everything you thought you knew about evolution, robot intelligence, and life itself.

Mimicry is a classic example of adaptation through natural selection. The traditional focus of mimicry research has been on defence in animals, but there is now also a highly-developed and rapidly-growing body of research on floral mimicry in plants. This has coincided with a revolution in genomic tools, making it possible to explore which genetic and developmental processes underlie the sometimes astonishing changes that give rise to floral mimicry. Being literally rooted to one spot, plants have to cajole animals into acting as couriers for their pollen. Floral mimicry encompasses a set of evolutionary strategies whereby plants imitate the food sources, oviposition sites, or mating partners of animals in order to exploit them as pollinators. This first definitive book on floral mimicry discusses the functions of visual, olfactory, and tactile signals, integrating them into a broader theory of organismal mimicry that will help guide future research in the field. It addresses the fundamental question of whether the evolutionary and ecological principles that were developed for protective mimicry in animals can also be applied to floral mimicry in plants. The book also deals with the functions of floral rewardlessness, a condition which often serves as a precursor to the evolution of mimicry in plant lineages. The authors pay particular attention to the increasing body of research on chemical cues: their molecular basis, their role in cognitive misclassification of flowers by pollinators, and their implications for plant speciation. Comprehensive in scope and conceptual in focus, Floral Mimicry is primarily aimed at senior undergraduates, graduate students, and researchers in plant science and evolutionary biology.

How did social communication evolve in primates? In this volume, primatologists, linguists, anthropologists, cognitive scientists and philosophers of science systematically analyze how their specific disciplines demarcate the research questions and methodologies involved in the study of the evolutionary origins of social communication in primates in general and in humans in particular. In the first part of the book, historians and philosophers of science address how the epistemological frameworks associated with primate communication and language evolution studies have changed over time and how these conceptual changes affect our current studies on the subject matter. In the second part, scholars provide cutting-edge insights into the various means through which primates communicate socially in both natural and experimental settings. They examine the behavioral building blocks by which primates communicate and they analyze what the cognitive requirements are for displaying communicative acts. Chapters highlight cross-fostering and language experiments with primates, primate mother-infant communication, the display of emotions and expressions, manual gestures and vocal signals, joint attention, intentionality and theory of mind. The primary focus of the third part is on how these various types of communicative behavior possibly evolved and how they can be understood as evolutionary precursors to human language. Leading scholars analyze how both manual and vocal gestures gave way to mimetic and imitational protolanguage and how the latter possibly transitioned into human language. In the final part, we turn to the hominin lineage, and anthropologists, archeologists and linguists investigate what the necessary neurocognitive, anatomical and behavioral features are in order for human language to evolve and how language differs from other forms of primate communication.

Since the publication in 1859 of Darwin's Origin of Species, debate over the theory of evolution has been continuous and often impassioned. In recent years, opponents of "Darwin's dangerous idea" have mounted history's most sophisticated and generously funded attack, claiming that evolution is "a theory in crisis." Ironically, these claims are being made at a time when the explosion of information from genome projects has revealed the most compelling and overwhelming evidence of evolution ever discovered. Much of the latest evidence of human evolution comes not from our genes, but from so-called "junk DNA," leftover relics of our evolutionary history that make up the vast majority of our DNA.
Relics of Eden explores this powerful DNA-based evidence of human evolution. The "relics" are the millions of functionally useless but scientifically informative remnants of our evolutionary ancestry trapped in the DNA of every person on the planet. For example, the analysis of the chimpanzee and Rhesus monkey genomes shows indisputable evidence of the human evolutionary relationship with other primates. Over 95 percent of our genome is identical with that of chimpanzees and we also have a good deal in common with other animal species.
Author Daniel J. Fairbanks also discusses what DNA analysis reveals about where humans originated. The diversity of DNA sequences repeatedly confirms the archeological evidence that humans originated in sub-Saharan Africa (the "Eden" of the title) and from there migrated through the Middle East and Asia to Europe, Australia, and the Americas. In conclusion, Fairbanks confronts the supposed dichotomy between evolution and religion, arguing that both science and religion are complementary ways to seek truth. He appeals to the vast majority of Americans who hold religious convictions not to be fooled by the pseudoscience of Creationists and Intelligent Design advocates and to abandon the false dichotomy between religion and real science.
This concise, very readable presentation of recent genetic research is completely accessible to the nonspecialist and makes for enlightening and fascinating reading.

The marriage of evolutionary biology with developmental biology has resulted in the formation of a new field, evolutionary developmental biology, or evo-devo. This volume reviews current research findings and thought in the broad field of evo-devo, looking at the developmental genetic mechanisms that cause variation and how alterations of these mechanisms can generate novel structural changes in a variety of plant and animal life.

This is the first book to consider the major implications for culture of the new science of biosemiotics. The volume is mainly aimed at an audience outside biosemiotics and semiotics, in the humanities and social sciences principally, who will welcome elucidation of the possible benefits to their subject area from a relatively new field. The book is therefore devoted to illuminating the extent to which biosemiotics constitutes an 'epistemological break' with 'modern' modes of conceptualizing culture. It shows biosemiotics to be a significant departure from those modes of thought that neglect to acknowledge continuity across nature, modes which install culture and the vicissitudes of the polis at the centre of their deliberations. The volume exposes the untenability of the 'culture/nature' division, presenting a challenge to the many approaches that can only produce an understanding of culture as a realm autonomous and divorced from nature.

In 1859, an amateur British naturalist published a book of findings that shook the scientific community to its core and changed the structure of religion and science as we know them. The product of over 20 years of research, The Origin of Species challenged the popular belief that species could not evolve and argued that species can adapt to their environment and develop accordingly. Although other scientists had observed some of the phenomena that Charles Darwin addressed, he was the first to theorize that natural selection, and later, evolution, were viable explanations for the origins of life. The implications of Darwin's findings still reverberate today, in the classroom, in the courtroom, and at the highest legislative levels. Lively thematic chapters explore how Darwin came to the conclusions published in The Origin of Species-and in later works such as The Descent of Man-from his early years at Cambridge, to his observations of species on the HMS Beagle voyages, through the 20 years of research that culminated in Origin. Also included is an insightful discussion of Darwin's impact as it is felt today, from movies and popular culture to the current Intelligent Design controversy. Biographies of influential figures, primary source letters and selections from Origin, a glossary of terms, and an extensive annotated bibliography round out this accessible work.

Michael Ruse is one of the foremost Charles Darwin scholars of our time. For forty years he has written extensively on Darwin, the scientific revolution that his work precipitated, and the nature and implications of evolutionary thinking for today. Now, in the year marking the two hundredth anniversary of Darwin's birth and the one hundred fiftieth anniversary of his masterpiece, On the Origin of Species, Ruse reevaluates the legacy of Darwin in this collection of new and recent essays.
Beginning with pre-Darwinian concepts of organic origins proposed by the great German philosopher Immanuel Kant, Ruse shows the challenges that Darwin's radically different idea faced. He then discusses natural selection as a powerful metaphor; Alfred Russel Wallace, the co-discoverer of the theory of evolution; Herbert Spencer's contribution to evolutionary biology; the synthesis of Mendelian genetics and natural selection; the different views of Julian Huxley and George Gaylord Simpson on evolutionary ethics; and the influence of Darwin's ideas on literature. In the final section, Ruse brings the discussion up to date with a consideration of "evolutionary development" (dubbed "evo devo") as a new evolutionary paradigm and the effects of Darwin on religion, especially the debate surrounding Intelligent Design theory.
Ruse offers a fresh perspective on topics old and new, challenging the reader to think again about the nature and consequences of what has been described as the biggest idea ever conceived.

Have you ever wondered what could happen when we discover another communicating species outside the Earth? This book addresses this question in all its complexity. In addition to the physical barriers for communication, such as the enormous distances where a message can take centuries to reach its recipient, the book also examines the biological problems of communicating between species, the problems of identifying a non-Terrestrial intelligence, and the ethical, religious, legal and other problems of conducting discussions across light years. Most of the book is concerned with issues that could impinge on your life: how do we share experiences with ETI? Can we make shared laws? Could we trade? Would they have religion? The book addresses these and related issues, identifying potential barriers to communication and suggesting ways we can overcome them. The book explores this topic through reference to human experience, through analogy and thought experiment, while relying on what is known to-date about ourselves, our world, and the cosmos we live in.
