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.
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.
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.
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 book aims to introduce the reader to the emerging field of Evolutionary Systems Biology, which approaches classical systems biology questions within an evolutionary framework. An evolutionary approach might allow understanding the significance of observed diversity, uncover "evolutionary design principles" and extend predictions made in model organisms to others. In addition, evolutionary systems biology can generate new insights into the adaptive landscape by combining molecular systems biology models and evolutionary simulations. This insight can enable the development of more detailed mechanistic evolutionary hypotheses.
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.
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.
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. "
'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.
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.
Evolution: The Basics is an engaging introduction to the history, development and science of the theory of evolution. Beginning pre-Darwin and concluding with the latest research and controversies, readers are introduced to the origins of the idea of evolution, the ways in which it has developed and been adapted over time and the science underpinning it all. Topics addressed include: ? early theories of evolution Evolution: The Basics examines the role of evolution in current debates and discusses the possible future developments in the field. This book is invaluable reading for all students and individuals seeking to understand the wide ranging sphere of evolutionary theory.
This provocative study provides a stimulating critique of contemporary evolutionary thought, analysing the Modern Synthesis first developed by Theodosius Dobzhansky, Ernst Mayr, and George Gaylord Simpson. Written by an eminent evolutionary biologist (the co-founder of the theory of punctuated equilibria), this highly readable book argues that only genes and organisms are taken as historic 'individuals' in conventional theory. Eldredge proposes that species, higher taxa, and ecological entities such as populations and communities should also be construed as individuals - an approach yielding the ecological and genealogical hierarchies that interact to produce evolution. This clearly stated, controversial work will provoke much debate among evolutionary biologists, systematicists, palaeontologists and ecologists, as well as lay readers.
Conservation genetics focuses on understanding the role and
requirement of genetic variation for population persistence.
However, considerable debate now surrounds the role of genetic
factors (as opposed to non-genetic factors such as habitat
destruction etc.) in population extinction, and a comprehensive
synthesis is now timely. Can extinction be explained by habitat
destruction alone or is lack of genetic variation a part of the
explanation? The book thoroughly reviews the arguments for a role
of genetics in the present biodiversity crisis. It describes the
methods used to study genetic variation in endangered species and
examines the influence of genetic variation in the extinction of
species.
The order Rodentia is the most abundant and successful group of mammals, and it has been a focal point of attention for compar ative and evolutionary biologists for many years. In addition, rodents are the most commonly used experimental mammals for bio medical research, and they have played a central role in investi gations of the genetic and molecular mechanisms of speciation in mammals. During recent decades, a tremendous amount of new data from various aspects of the biology of living and fossil rodents has been accumulated by specialists from different disciplines, ranging from molecular biology to paleontology. Paradoxically, our understanding of the possible evolutionary relationships among different rodent families, as well as the possible affinities of rodents with other eutherian mammals, has not kept pace with this information "explosion. " This abundance of new biological data has not been incorporated into a broad synthesis of rodent phylo geny, in part because of the difficulty for any single student of rodent evolution to evaluate the phylogenetic significance of new findings from such diverse disciplines as paleontology, embryology, comparative anatomy, molecular biology, and cytogenetics. The origin and subsequent radiation of the order Rodentia were based primarily on the acquisition of a key character complex: specializations of the incisors, cheek teeth, and associated mus culoskeletal features of the jaws and skull for gnawing and chewing."
Originally published in 1969, the aim of this book is to tell the story of the major discoveries which have been made and the attitude of the world at large to these discoveries during the ten decades since Darwin published On the Origin of Species in 1859. For anyone interested in man's past and in understanding the significance of each new discovery relating to human evolution, this reissue will be of great value.
In this deep examination of functional morphology, a renowned paleoanthropologist offers a new way to investigate human evolution through the fossil record. It is common for two functional anatomists to examine the exact same fossil material, yet argue over its evolutionary significance. How can this be? Traditionally, paleoanthropology has interpreted hominin fossil morphology by first considering the ecological challenges hominins faced, then drawing adaptive inferences based on the idea that skeletal morphology is largely a reflection of paleoecology. In Functional Inference in Paleoanthropology, innovative paleoanthropologist David J. Daegling suggests that researchers can resolve dichotomous interpretations of the fossil record by instead focusing on the biology and development of the bones themselves-such as measurable responses to deformations, stresses, and damage. Critically exploring how scientists probe and interpret fossil morphology for behavioral and adaptive inferences, Daegling makes the case that an intelligible science of functional morphology in the fossil record is impossible without the inclusion of this mechanobiological perspective. Drawing on historical examples from long-standing debates on the emergence of bipedality and the dietary shifts that facilitated the emergence of the hominin clade, Daegling traces the disjunctions between theoretical principles of comparative morphology and methodological practice in the paleontological context of human evolution. Sharing rich findings from recent decades of research in skeletal biomechanics, Functional Inference in Paleoanthropology examines how bone adapts over the lifespan, what environmental factors influence its quality, and how developmental constraints limit the skeleton's adaptive potential over evolutionary time. |
