More than 25 years ago, the first major review of primate communication appeared (Altmann, 1967). Since then, information on the communicative abilities of primates increased rapidly, resulting, 15 years later, in the appearance of the first volume in which signaling systems were analyzed in a broader variety of primate groups within an evolutionary perspective (Snowdon, Brown and Petersen, 1982). Seven years later, the first volume dedicated solely to primate vocal communication appeared (Todt, Goedeking and Symmes, 1988) and another four years later a volume followed in which nonverbal vocal communication in non-human primates and human infants was compared (Papousek, Jurgens and Papousek, 1992). None of these volumes, however, provided information about current technical advances in the field of bioacoustics, especially in digital sound analyzing systems, which offer primatologists, anthropologists and linguists nowadays a variety of rapid methods for analyzing human speech and non-human primate vocalizations in a quantitative and comparative way. Choosing the right method is difficult if a synopsis of these tools is lacking. Furthermore, information was particularly lacking on the natural signaling systems of two important primate groups, the prosimians and the apes. Likewise, new and unexpected insights into the ontogeny and evolution of vocal communication were gained during the past few years by the use of highly sophisticated sound analysis and statistical techniques.

Several years ago, we realized that the most prominent ideas that had been ex pressed about the origin and early evolution of the Metazoa seemed to have been developed chiefly by zoologists using evidence from modern species without reference to the fossil record. Paleontologists had, in fact, put forth their own ideas but the zoological and the paleontological evidence were about the problem, seldom considered together, especially by zoologists. We believed that the paleon tological documentation of the first Metazoa was too scattered, too obscure to Western readers, and much of it too recent to have been readily available to our colleagues in zoology. Whether or not that was entirely true, we thought that a single volume reviewing the fossil record of the earliest Metazoa would be useful to many in both paleontology and zoology, especially since so much new informa tion has been developed in the last few years. Some of this information has been summarized in general articles recently, but an overview of most of the field does not exist. We therefore organized this book in five parts so that the evidence could be placed in perspective and summarized and inferences made from it. Part I intro duces the previous hypotheses that have been proposed for the origin and early radiation of Metazoa. Part II consists of two summary chapters that set the sedi mentological, geochemical, and biological background to the known radiations of Metazoa."

In this work aggression and conflict in man and other primates are interpreted in the light of evolutionary biology and game theory models.Unitlnow interdisciplinary collaboration between the humanities and the natural sciences has been rare and hampered by different methodologies and terminology. Nevertheless, such cooperation is essential for elucidating the causes and consequences of aggression in humans and in explaining what shape aggression takes in particular situations. The aim of this volume is to present empirical and theoretical studies from biologists and social scientists to create an interdisciplinary framework for understanding aggression.

This interdisciplinary book consists of the proceedings of the Alexander Ivanovich Oparin lOOth Anniversary Conference, The Third Trieste Conference on Chemical Evolution, which took place at the International Centre for Theoretical Physics from 29 August till 2 September, 1994. A general overview of Oparin's life and work is followed by a review of Alfonso Herera, another pioneer in the studies of the origin of life. The subject matter is organized in ten sections corresponding to various aspects of our current understanding of the subject that was initiated by Oparin. These subjects were covered by fifty three speakers. There were sixty seven participants from a wide geographical distribution; twenty seven countries were represented. We have included the invited lecture of Professor Igor Kulaev, who was unable to be present at the conference for reasons beyond his control. The conference was generously supported by the International Centre for Theoretical Physics, the Commission of the European Communities, the International Centre for Genetic Engineering and Biotechnology, the International Centre for Science and High Technology, and UNESCO. Cyril Ponnamperuma, University of Maryland, U.S.A. Julian Chela-Flores, ICTP, Italy, and IDEA, Venezuela. xi FOREWORD As this volume was going to press we learnt of the untimely death of Cyril Ponnamperuma who died of cardiac arrest on December 20, 1994.

This volume summarises the outcome of the 13th Workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP) on if, and if so under what conditions phytoplankton assemblages reach equilibrium in natural environments. Quite a number of ecological concepts use terms such as: ecological equilibrium, stability, steady-state, climax, stable state, etc. However, these ecological concepts often have been "translations" of scientific theories developed in physics or chemistry but they almost always lack scientific corroboration, the problem being that often these concepts remain vague and they are not formally defined. Here an attempt to formally recognize what "equilibrium" is in phytoplankton ecology is traced. The book also contains papers by leading scientists on the taxonomy of two selected key groups: cryptomonads and filamentous cyanoprokaryotes. This volume is addressed to all those involved in phytoplankton taxonomy and ecology and in ecology itself.

Ever since Darwin, scholars have noted that cultural entities such as languages, laws, firms and theories seem to 'evolve' through sequences of variation, selection and replication, in many ways just like living organisms. These essays consider whether this comparison is 'just a metaphor', or whether modern evolutionary theory can help us to understand the dynamics of different cultural domains.

The 'evolutionary paradigm of rationality' has a significant role to play throughout the human sciences, but raises complex issues in every cultural context where it is applied. By fostering discussion between scholars from a wide range of research traditions, this volume aims to influence the evolution of all of them.

Timing, racing, combating, struggling and targeting are some actions through which cellular fate could be reflected and evaluated. Interaction between cell territory and environment occur during pre-embryonic, fetal development, and post-natal periods. What the researchers observe as the outcome of telomeres behavior is only the peak of an ice mountain within a stormy ocean. Cellular life depends on programmed behavior of telomeres, capable to surprise the cells. Telomeres provide an introduction to the history of our cells which govern the quality of life and status of health. Telomeres as the cooperative territory are capable of stabilizing the chromosomal territory. The status of telomeres reflects the key information, announcing the real age of individuals, and may be a valuable marker for prognosis and predicting cancer. Telomere territory is characterized with a multi-disciplinary manner. Therefore, this book is aimed to offer a wide range of chapters, hoping to be useful for diverse audiences, including hematologists-oncologists, radiotherapists, surgeons, cancer researchers, and all the sectors who affect the macro- and micro- environmental domains. Finally, telomeres are sensitive, cooperative, and trustable targets. It is worth to state that 'telomeres are messengers of NATURE', let's to know them as they are.

Wild emmer is the progenitor of most cultivated wheats and thus an important source of wheat improvement. This book draws the results from multidisciplinary studies on the ecological, genetic, genomic, agronomic, and evolutionary aspects of wild emmer, conducted at many labs around the world.It is divided into the following parts: Origin and Evolution of Wheat - Population Genetics of Wild Emmer Wheat at the Protein and DNA Levels - Genetic Resources of Wild Emmer for Wheat Improvement - Genome Organization and Genetic Mapping - Conclusions and Prospects.The authors describe the evolution of wild emmer as a model organism of a selfer in evolutionary biology, and its rich potential genetic resources for wheat improvement.

Movement, dispersal, and migration on land, in the air, and in water, are pervading features of animal life. They are performed by a huge variety of organisms, from the smallest protozoans to the largest whales, and can extend over widely different distance scales, from the microscopic to global. Integrating the study of movement, dispersal, and migration is crucial for a detailed understanding of the spatial scale of adaptation, and for analysing the consequences of landscape and climate change as well as of invasive species. This novel book adopts a broad, cross-taxonomic approach to animal movement across both temporal and spatial scales, addressing how and why animals move, and in what ways they differ in their locomotion and navigation performance. Written by an integrated team of leading researchers, the book synthesizes our current knowledge of the genetics of movement, including gene flow and local adaptations, whilst providing a future perspective on how patterns of animal migration may change over time together with their potential evolutionary consequences. Novel technologies for tracking the movement of organisms across scales are also discussed, ranging from satellite devices for tracking global migrations to nanotechnology that can follow animals only a millimetre in size. Animal Movement Across Scales is particularly suitable for graduate level students taking courses in spatial animal ecology, animal migration, and 'movement ecology', as well as providing a source of fresh ideas and opinions for those already active within the field. It will also be of interest and use to a broader audience of professional biologists interested in animal movements and migrations.

Building on a range of disciplines - from biology and anthropology to philosophy and linguistics - this book draws on the expertise of leading names in the study of organic, mental and cultural codes brought together by the emerging discipline of biosemiotics. The book's 18 chapters present a range of experimental evidence which suggests that the genetic code was only the first in a long series of organic codes, and that it has been the appearance of new codes - organic, mental and cultural - that paved the way for the major transitions in the history of life. While the existence of many organic codes has been proposed since the 1980s, this volume represents the first multi-authored attempt to deal with the range of codes relevant to life, and to reveal the ubiquitous role of coding mechanisms in both organic and mental evolution. This creates the conditions for a synthesis of biology and linguistics that finally overcomes the old divide between nature and culture.

Research in whale origins is now in an explosive phase, with a cascade of discoveries adding to our understanding of the evolutionary pattern and a suite of new techniques being applied to address new questions. The objective of this volume is to provide a snapshot of this explosion. The volume paints the scene with a broad brush. Taken together the chapters clearly indicate that cetacean origins is a field that is dynamic, multidisciplinary, and that the end of the explosive phase is not in sight.

Despite decades of work in evolutionary algorithms, there remains a lot of uncertainty as to when it is beneficial or detrimental to use recombination or mutation. This book provides a characterization of the roles that recombination and mutation play in evolutionary algorithms. It integrates prior theoretical work and introduces new theoretical techniques for studying evolutionary algorithms. An aggregation algorithm for Markov chains is introduced which is useful for studying not only evolutionary algorithms specifically, but also complex systems in general. Practical consequences of the theory are explored and a novel method for comparing search and optimization algorithms is introduced. A focus on discrete rather than real-valued representations allows the book to bridge multiple communities, including evolutionary biologists and population geneticists.

What can economics, the natural and the social sciences learn from each other in better understanding complex forms of change? How far can models, methodologies or metaphors that have been used successfully in one disciplinary field be 'exported' and meaningfully applied to other fields? Distinguished researchers from across the globe assess, in a rare example of successful cross-disciplinary engagement, the explanatory power of chaos theory, new evolutionary theory, path dependency, neo-institutional economics, multiple modernities and historical institutionalism. The book provides an exciting panorama of state of the art thinking and new avenues to combining the power of various traditions of thought.

There is hardly any university, college, or even high school left where they do not teach Darwinism-and rightly so. Yet, most of these places do more preaching than teaching. They teach more than they should, and at the same time, they teach less than they should. Most books on Darwinism are either oriented on biology or philosophy, but this book tries to combine both approaches, so it explains the biological aspects for (future) philosophers as well as the philosophical aspects for (future) biologists. It leaves Darwinism intact, but removes the "sting" that many of its opponents dislike. In what Verschuuren calls "The Good" parts of Darwin's legacy, the author explores what Darwin's great contributions are to the study and theory of evolution. At the same time, the book will also delve into the areas where Darwin's thoughts were not so perfect or even wrong, especially in a philosophical sense - "The Not So Good" parts of his legacy. Almost all books on the philosophy of biology, and neo-Darwinism in particular, were born in the cradle of logical positivism or linguistic analysis. This book, on the other hand, tries to cross the border between the physical and the meta-physical.

The ideal textbook for non-science majors, this lively and engaging introduction encourages students to ask questions, assess data critically and think like a scientist. Building on the success of the previous editions, Dinosaurs has been reorganised and extensively rewritten in response to instructor and student feedback. It continues to make science accessible and relevant through its clear explanations and extensive illustrations. Updated to reflect recent fossil discoveries and to include new taxa, the text guides students through the dinosaur groups, emphasising scientific concepts rather than presenting endless facts. It is grounded in the common language of modern evolutionary biology - phylogenetic systematics - so that students examine dinosaurs as professional paleontologists do. The key emerging theme of feathered dinosaurs, and the many implications of feathers, have been integrated throughout the book, highlighted by the inclusion of stunning new photographs in this beautifully illustrated text, now in full colour throughout.

This book collects essays published in journals including Commentary, The Weekly Standard, and elsewhere. It centers on three profound mysteries: the existence of the human mind; the existence and diversity of living creatures; and the existence of matter. How they did they come into being? The author, Dr. David Berlinski, is a senior fellow at the Discovery Institute and formerly a fellow at the Institut des Hautes tudes Scientifiques in France. His other books include The Devil's Delusion: Atheism and Its Scientific Pretensions, Newton's Gift, and A Tour of the Calculus.

'Jackie Higgins's lyrical, literate style will charm you while her book stuns your imagination with strange, other-worldly truths' Richard Dawkins Sentient assembles a menagerie of zoological creatures - from land, air, sea and all four corners of the globe - to understand what it means to be human. Through their eyes, ears, skins, tongues and noses, the furred, finned and feathered reveal how we sense and make sense of the world, as well as the untold scientific revolution stirring in the field of human perception. The harlequin mantis shrimp can throw a punch that can fracture aquarium walls but, more importantly, it has the ability to see a vast range of colours. The ears of the great grey owl have such unparalleled range and sensitivity that they can hear twenty decibels lower than the human ear. The star-nosed mole barely fills a human hand, seldom ventures above ground and poses little threat unless you are an earthworm, but its miraculous nose allows it to catch those worms at astonishing speed - as little as one hundred and twenty milliseconds. Here, too, we meet the four-eyed spookfish and its dark vision; the vampire bat and its remarkable powers of touch; the bloodhound and its hundreds of millions of scent receptors, as well as the bar-tailed godwit, the common octopus, giant peacocks, cheetahs and golden orb-weaving spiders. Each of these extraordinary creatures illustrates the sensory powers that lie dormant within us. In this captivating book, Jackie Higgins explores this evolutionary heritage and, in doing so, enables us to subconsciously engage with the world in ways we never knew possible.

How better than to mark the 150th anniversary of Darwin's book on human evolution than by challenging his theory with an updated version which instead places the female species at the centre of the theory. Sexual selection may have created us, but by refusing to take a good hard look at ourselves and our impact on the planet, we may be granting natural selection the power to eliminate us. A fascinating book which is both controversial and entertaining and which will deepen your understanding of human evolution like you would never have imagined. Heather deepens our understanding of human evolution by including genetic discoveries that were unavailable in 1871 when Darwin wrote The Descent of Man and Selection in Relation to Sex. She offers an updated version of the theory by viewing the courtship dance through a female lens. Darwin was correct in acknowledging that sexual selection is driven by female choice, but he was seriously mistaken in granting a female no active influence and depicting her as passively succumbing to the charms of the triumphant male who had bested another in a competition to win her favour or to the one who had tickled her fancy with his feathers. In the process of her doctoral research, Heather analysed hundreds of hours of tape-recorded interviews in which women identified the traits that made specific men in their lives sexually and reproductively attractive. Their insights help us make sense of recent studies that leave researchers scratching their heads when the species they study don't appear to be playing by the rules, according to Darwin. We are in the midst of two immediate existential crises-climate change and growing economic inequality-caused by human behaviour. If we are to be successful in addressing these challenges, Remoff argues that we need to come to terms with the double-edged sword at the heart of all that makes us special. Who are we? What selection pressures forged our species specific traits? Of all the trillions of species that have ever existed on this planet only one, Homo sapiens, has mastered language, the art of symbolic communication. Did female passions play a role in triggering our way with words? Absolutely. Our choice of reproductive partners shaped not only language ability but also many of the other traits that define us today.

Since its inception, paleoanthropology has been closely wedded to the idea that big-game hunting by our hominin ancestors arose, first and foremost, as a means for acquiring energy and vital nutrients. This assumption has rarely been questioned, and seems intuitively obvious-meat is a nutrient-rich food with the ideal array of amino acids, and big animals provide meat in large, convenient packages. Through new research, the author of this volume provides a strong argument that the primary goals of big-game hunting were actually social and political-increasing hunter's prestige and standing-and that the nutritional component was just an added bonus.
Through a comprehensive, interdisciplinary research approach, the author examines the historical and current perceptions of protein as an important nutrient source, the biological impact of a high-protein diet and the evidence of this in the archaeological record, and provides a compelling reexamination of this long-held conclusion. This volume will be of interest to researchers in Archaeology, Evolutionary Biology, and Paleoanthropology, particularly those studying diet and nutrition.

Many multicellular animals do not require oxygen to live but respire anaerobically. Some of these have adapted to "hostile" environments, such as sulphide rich habitats, others live as parasites within host organisms, while others still can perhaps be said to look back on the early days of life on earth before anaerobic respiration had evolved. This comprehensive volume lays out detailed summaries of the strategies for anero- or anoxy-biosis employed by each major group of metazoan animals. It begins with a description of the physical chemistry of oxygen, followed by a dissertation on the perils - and opportunities - created for life by oxygen derived free radicals. It moves on to examine the geochronology of the accumulation of oxygen in the environment and to analyze the first explosive adaptive radiation of the Metazoa in the Ediacarian and early Cambrian. It then explores the biochemistry of sulphide dependent organisms and follows with a detailed account of the evolution of fumarate reductase, the enzyme system that makes anaerobiosis possible in many invertebrate phyla. After the survey of invertebrate phyla, there is a chapter concerned with the strategies adopted by various vertebrates for anoxybiotic survival, and one on the dependence of many vertebrates on anaerobic processes. The contributors are authorities from around the world. The approach to the subject is an evolutionary one, drawing from many fields in biology. This book should be of interest to parasitologists, comparative biochemists, evolutionary biologists, palaeontologists and geochemists.

The present book gives an overview on the similarities and differences of the various translation systems. Moreover, it highlights the mechanisms and control of translation in mitochondria and other organelles such as chloroplasts, plastids and apicoplasts in different organisms. Lastly, it offers an outlook on future developments and applications that might be made possible by a better understanding of translation in mitochondria and other organelles. "

This book challenges the assumption that morphological data are inherently unsuitable for phylogeny reconstruction, argues that both molecular and morphological phylogenies should play a major role in systematics, and provides the most comprehensive review of the comparative anatomy, homologies and evolution of the head, neck, pectoral and upper limb muscles of primates. Chapters 1 and 2 provide an introduction to the main aims and methodology of the book. Chapters 3 and 4 and Appendices I and II present the data obtained from dissections of the head, neck, pectoral and upper limb muscles of representative members of all the major primate groups including modern humans, and compare these data with the information available in the literature. Appendices I and II provide detailed textual (attachments, innervation, function, variations and synonyms) and visual (high quality photographs) information about each muscle for the primate taxa included in the cladistic study of Chapter 3, thus providing the first comprehensive and up to date overview of the comparative anatomy of the head, neck, pectoral and upper limb muscles of primates. The most parsimonious tree obtained from the cladistic analysis of 166 head, neck, pectoral and upper limb muscle characters in 18 primate genera, and in representatives of the Scandentia, Dermoptera and Rodentia, is fully congruent with the evolutionary molecular tree of Primates, thus supporting the idea that muscle characters are particularly useful to infer phylogenies. The combined anatomical materials provided in this book point out that modern humans have fewer head, neck, pectoral and upper limb muscles than most other living primates, but are consistent with the proposal that facial and vocal communication and specialized thumb movements have probably played an important role in recent human evolution. This book will be of interest to primatologists, comparative anatomists, functional morphologists, zoologists, physical anthropologists, and systematicians, as well as to medical students, physicians and researchers interested in understanding the origin, evolution, homology and variations of the muscles of modern humans. Contains 132 color plates.
