Plant-herbivore interactions are a central topic in evolutionary ecology. Historically, their study has been a cornerstone for coevolutionary theory. Starting from classic ecological studies at the phenotypic level, it has since expanded to molecular and genomic approaches. After a historical perspective, the book's subsequent chapters cover a wide range of topics: from populations to ecosystems; plant- and herbivore-focused studies; in natural and in man-modified ecosystems; and both micro- and macro-evolutionary levels. All chapters include valuable background information and empirical evidence. Given its scope, the book will be of interest to both students and researchers, and will hopefully stimulate further research in this exciting field of evolutionary biology.
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.
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.
This book is about morphogenesis as the genesis of forms. It is not restricted to plants growing from seed or animals developing from an embryo (although these do supply the most abundant examples) but also addresses kindred processes, from inorganic to social to biomorphic technology. It is about our morphogenetic universe: unplanned, unfair and frustratingly complicated but benevolent in allowing us to emerge, survive, and inquire into its laws.
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.
The study of religion by the humanities and social sciences has become receptive for an evolutionary perspective. Some proposals model the evolution of religion in Darwinian terms, or construct a synergy between biological and non-Darwinian processes. The results, however, have not yet become truly interdisciplinary. The biological theory of evolution in form of the Extended Evolutionary Synthesis (EES) is only sparsely represented in theories published so far by scholars of religion. Therefore this book reverses the line of view and asks how their results assort with evolutionary biology: How can the subject area "religion" integrated into behavioral biology? How is theory building affected by the asymmetry between the scarce empirical knowledge of prehistoric religion, and the body of knowledge about extant and historic religions? How does hominin evolution in general relate to the evolution of religion? Are there evolutionary pre-adaptations? Subsequent versions of evolutionary biology from the original Darwinism to EES are used in interdisciplinary constructs. Can they be integrated into a comprehensive theory? The biological concept most often used is co-evolution, in form of a gene-culture co-evolution. However, the term denotes a process different from biological co-evolution. Important EES concepts do not appear in present models of religious evolution: e.g. neutral evolution, evolutionary drift, evolutionary constraints etc. How to include them into an interdisciplinary approach? Does the cognitive science of religion (CSR) harmonize with behavioral biology and the brain sciences? Religion as part of human culture is supported by a complex, multi-level behavioral system. How can it be modeled scientifically? The book addresses graduate students and researchers concerned about the scientific study of religion, and biologist interested in interdisciplinary theory building in the field.
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.
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.
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.
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. "
Everybody Out of the Pond At the Water's Edge will change the way you think about your place in the world. The awesome journey of life's transformation from the first microbes 4 billion years ago to Homo sapiens today is an epic that we are only now beginning to grasp. Magnificent and bizarre, it is the story of how we got here, what we left behind, and what we brought with us. We all know about evolution, but it still seems absurd that our ancestors were fish. Darwin's idea of natural selection was the key to solving generation-to-generation evolution -- microevolution -- but it could only point us toward a complete explanation, still to come, of the engines of macroevolution, the transformation of body shapes across millions of years. Now, drawing on the latest fossil discoveries and breakthrough scientific analysis, Carl Zimmer reveals how macroevolution works. Escorting us along the trail of discovery up to the current dramatic research in paleontology, ecology, genetics, and embryology, Zimmer shows how scientists today are unveiling the secrets of life that biologists struggled with two centuries ago. In this book, you will find a dazzling, brash literary talent and a rigorous scientific sensibility gracefully brought together. Carl Zimmer provides a comprehensive, lucid, and authoritative answer to the mystery of how nature actually made itself.
How have our emotions shaped the course of human history? And how have our experience and understanding of emotions evolved with us? We humans like to think of ourselves as rational creatures, who, as a species, have relied on calculation and intellect to survive. But many of the most important moments in our history had little to do with cold, hard facts and a lot to do with feelings. Events ranging from the origins of philosophy to the birth of the world's major religions, the fall of Rome, the Scientific Revolution, and some of the bloodiest wars that humanity has ever experienced can't be properly understood without understanding emotions. In A Human History of Emotion, Richard Firth-Godbehere takes readers on a fascinating and wide-ranging tour of the central and often under-appreciated role emotions have played in human societies around the world and throughout history - from Ancient Greece to Gambia, Japan, the Ottoman Empire, Britain, and beyond. Drawing on psychology, neuroscience, philosophy, art and religious history, A Human History of Emotion vividly illustrates how our understanding and experience of emotions has changed over time, and how our beliefs about feelings - and our feelings themselves - profoundly shaped us and the world we inhabit.

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.
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.
Chronic inflammation is one of the major pathological bases manifesting the development of gastric cancers, hepatitis and hepatocellular carcinoma, cervical cancer, ulcerative colitis and colorectal cancer [1]. Microbial infections, viral infections and autoimmune responses can lead to chronic inflammation-associated cancer formation. Human herpesviruses, such as human cytomegalovirus (HCMV) and Kaposi sarcoma herpesvirus (KSHV) are known to be associated with tumorigenesis and tumor progression. HCMV infection potentiates malignancies of colon cancer and malignant glioma [2,3]. KSHV was initially discovered from Kaposi's sarcoma lesion of an AIDS patient [4]. It was subsequently discovered that KSHV contributed to the pathogenesis of KS, primary effusion lymphoma [5] and lymphoproliferative disorder multicentric Castleman's disease. Emerging evidence shows that herpesvirus infection interferes or inhibits host cell immune defense and maintains a tumor-promoting microenvironment by expressing virulent homologues of host cell proteins that disturb normal cell cycle progression and leads to apoptosis of the host cells. For example, cellular growth and transformation are induced by viral-encoded homologues of cytokines, chemokines or chemokine receptors [6]. The constitutive expression of viral chemokine GPCRs triggers prolonged activation of G protein signaling and eventually becomes the major inputs for chronic leukocyte infiltration and cancer development. GPCRs can serve as proto-oncogenes since overexpression of various wild type GPCRs can transform cells in the presence of their specific ligands. Mutations on GPCRs may result in constitutive signaling and oncogenesis [7]. Naturally occurring mutations in GPCRs have been identified in human tumors [8,9].
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.
Through a series of essays concerning human eating seen from the perspective of contemporary biology/medicine and recent research articles, the book explores the links between food and Man's cultural and physical evolution. Each chapter has an introduction summarizing the basic knowledge in the field, discusses the recent research results, and confirms or challenges the established concepts, which opens new aspects and leads to new questions. This book catalyzes discussion between scientists working on one side in food science and on the other side in biological and biomedical research.
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."
DNA ancestry companies generate revenues in the region of $1bn a year, and the company 23andMe is said to have sold 10 million DNA ancestry kits to date. Although evidently popular, the science behind how DNA ancestry tests work is mystifying and difficult for the general public to interpret and understand. In this accessible and engaging book, Sheldon Krimsky, a leading researcher, investigates the methods that different companies use for DNA ancestry testing. He also discusses what the tests are used for, from their application in criminal investigations to discovering missing relatives. With a lack of transparency from companies in sharing their data, absent validation of methods by independent scientists, and currently no agreed-upon standards of accuracy, this book also examines the ethical issues behind genetic genealogy testing, including concerns surrounding data privacy and security. It demystifies the art and science of DNA ancestry testing for the general reader.
It has become received wisdom that our world is doomed, that we live in the End of Days. Bleak predictions by psychics and scientists alike portend extreme weather, droughts, famines and floods that will overtake humanity within the century, or sooner. If not global warming, then supervolcanoes, meteoric impacts, nuclear war, bioterrorism, or natural plagues will get us. But whatever happens, Michael Hanlon believes that humankind will go on...and on. The shape of things to come will be strange, and somewhat terrifying, but will very likely seem banal to the people who inhabit it in the future. Humankind may be thrown back to the Stone Age on hundreds of occasions and may come close to extinction. But recovery will follow--each time more rapidly than the last. The world of 10,000 years hence, let alone 100,000,000 years hence, will be strange and almost unrecognizable. But no matter how battered and re-born, it will still be "our" world, populated by "us" through eternity. |
