The origin of life has been investigated by many researchers from various research fields, such as Geology, Geochemistry, Physics, Chemistry, Molecular Biology, Astronomy and so on. Nevertheless, the origin of life remains unsolved. One of the reasons for this could be attributed to the different approaches that researchers have used to understand the events that happened on the primitive Earth. The origins of the main three members of the fundamental life system, as gene, genetic code and protein, could be only separately understood with these approaches. Therefore, it is necessary to understand the origins of gene, the genetic code, tRNA, metabolism, cell structure and protein not separately but comprehensively under a common concept in order to understand the origin of life, because the six members are intimately related to each other. In this monograph, the author offers a comprehensive hypothesis to explain the origin of life under a common concept. At the same time, the author offers the [GADV] hypothesis contrasting it with other current hypotheses and discusses the results of analyses of genes/proteins and the experimental data available in the exploration of the current knowledge in the field. This book is of interest for science students, researchers and the general public interested in the origin of life.
The scientific study of networks - computer, social, and biological - has received an enormous amount of interest in recent years. However, the network approach has been applied to the field of animal behaviour relatively late compared to many other biological disciplines. Understanding social network structure is of great importance for biologists since the structural characteristics of any network will affect its constituent members and influence a range of diverse behaviours. These include finding and choosing a sexual partner, developing and maintaining cooperative relationships, and engaging in foraging and anti-predator behavior. This novel text provides an overview of the insights that network analysis has provided into major biological processes, and how it has enhanced our understanding of the social organisation of several important taxonomic groups. It brings together researchers from a wide range of disciplines with the aim of providing both an overview of the power of the network approach for understanding patterns and process in animal populations, as well as outlining how current methodological constraints and challenges can be overcome. Animal Social Networks is principally aimed at graduate level students and researchers in the fields of ecology, zoology, animal behaviour, and evolutionary biology but will also be of interest to social scientists.
Origins: Genesis, Evolution and Biodiversity of Microbial Life in the Universe is the sixth unit of the book series Cellular Origins, Life in Extreme Habitats and Astrobiology (COLE) edited by Joseph Seckbach. In this book forty eminent scientists review their studies in the fields of Life from the beginning to the "Fact of Life." The history of Origin of Life and Astrobiology is well covered by these authors. Reviews cover the standard and alternative scenarios of the genesis of Life, while the chapters of "The First Cells" leading to the biodiversity and extremophiles of microbial Life. Among these extremophiles are the microbes living in the Life's limits, such as in high temperature, psychrophilic, UV radiation, and halophilic environments. The origin and history of Martian water is discussed followed by the possible biogeochemistry inside Titan. This new field of Astrobiology has been presented, from comets as a source of materials and Life on earth to the space for last Frontiers.

This book represents an evolutionary approach to defense mechanisms of all living organisms. The results achieved in developmental and comparative immunology are among the most interesting data in immunology. These results have great impact on our understanding fundamental problems of the pathology of the human immune system. At the same time, the field of evolutionary immunology provides not only inspiration for further investigation in biomedicine, but also a number of results applicable in clinical and commercial practice. This book evaluates the advantages and limitations of studying the development of defense reactions. In addition to reviewing the major and crucial achievements of the past, the book offers a comprehensive state-of-the-art treatise focused primarily on the latest experiments described in the last few years.
Darwin's notebooks provide an invaluable record of his scientific thinking and most importantly, the development of his theory of natural selection. This edition of the notebooks, prepared to the highest standard of textual editing, thus affords a unified view of Darwin's professional interests. The Red Notebook, used on the voyage of H. M. S. Beagle and afterwards in England, contains Darwin's first evolutionary statements. In July of 1837, Darwin began his 'Transmutation Notebooks' (B - E) devoted to the solution of the species problem and in the third notebook of this series he first formulated the theory of natural selection. This volume also contains Notebook A and the glen Roy Notebook on geology, Notebooks M and N on man and behaviour and a notebook labelled Questions and Experiments. Fresh transcriptions have been done for all previously published manuscripts, with readings made directly from Notebooks B, C, D and E, presenting them with previously excised pages and restored to their original sequence.
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.

Broad topics include the history of evolutionary biology, population genetics, quantitative genetics; speciation, life history evolution, evolution of sex and mating systems, evolutionary biogeography, evolutionary developmental biology, molecular and genome evolution, coevolution, phylogenetic methods, microbial evolution, diversification of plants and fungi, diversification of animals, and applied evolution.
Does Aging Stop? reveals the most paradoxical finding of recent
aging research: the cessation of demographic aging. The authors
show that aging stops at the level of the individual organism, and
explain why evolution allows this. The implications of this
counter-intuitive conclusion are profound, and aging research now
needs to accept three uncomfortable truths. First, aging is not a
cumulative physiological process. Second, the fundamental theory
that is required to explain, manipulate, and probe the phenomena of
aging comes from evolutionary biology. Third, strong-inference
experimental strategies for aging must be founded in evolutionary
research, not cell or molecular biology.
This edited volume examines the relationship between collective intentionality and inferential theories of meaning. The book consists of three main sections. The first part contains essays demonstrating how researchers working on inferentialism and collective intentionality can learn from one another. The essays in the second part examine the dimensions along which philosophical and empirical research on human reasoning and collective intentionality can benefit from more cross-pollination. The final part consists of essays that offer a closer examination of themes from inferentialism and collective intentionality that arise in the work of Wilfrid Sellars. Groups, Norms and Practices provides a template for continuing an interdisciplinary program in philosophy and the sciences that aims to deepen our understanding of human rationality, language use, and sociality.
The cognitive science of religion is an inherently heterogeneous subject, incorporating theory and data from anthropology, psychology, sociology, evolutionary biology, and philosophy of mind amongst other subjects. One increasingly influential area of research in this field is concerned specifically with exploring the relationship between the evolution of the human mind, the evolution of culture in general, and the origins and subsequent development of religion. This research has exerted a strong influence on many areas of religious studies over the last twenty years, but, for some, the so-called 'evolutionary cognitive science of religion' remains a deeply problematic enterprise. This book's primary aim is to engage critically and constructively with this complex and diverse body of research from a wide range of perspectives. To these ends, the book brings together authors from a variety of relevant disciplines, in the thorough exploration of many of the key debates in the field. These include, for example: can certain aspects of religion be considered adaptive, or are they evolutionary by-products? Is the evolutionary cognitive science of religion compatible with theism? Is the evolutionary cognitive approach compatible with other, more traditional approaches to the study of religion? To what extent is religion shaped by cultural evolutionary processes? Is the evolutionary account of the mind that underpins the evolutionary cognitive approach the best or only available account? Written in accessible language, with an introductory chapter by Ilkka Pyssiainen, a leading scholar in the field, this book is a valuable resource for specialists, undergraduate and graduate students, and newcomers to the evolutionary cognitive science of religion.
This book outlines the evolution of our political nature over two million years and explores many of the rituals, plays, films, and other performances that gave voice and legitimacy to various political regimes in our species' history. Our genetic and cultural evolution during the Pleistocene Epoch bestowed a wide range of predispositions on our species that continue to shape the politics we support and the performances we enjoy. The book's case studies range from an initiation ritual in the Mbendjela tribe in the Congo to a 1947 drama by Bertolt Brecht and include a popular puppet play in Tokugawa Japan. A final section examines the gradual disintegration of social cohesion underlying the rise of polarized politics in the USA after 1965, as such films as The Godfather, Independence Day, The Dark Knight Rises, and Joker accelerated the nation's slide toward authoritarian Trumpism.
Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis and the fusion of two gametes of different sexes or mating types. Sex-determination mechanisms are responsible for the sexual fate and development of sexual characteristics in an organism, be it a unicellular alga, a plant, or an animal. In many cases, sex determination is genetic: males and females have different alleles or different genes that specify their sexual morphology. In animals, this is often accompanied by chromosomal differences. In other cases, sex may be determined by environmental (e.g. temperature) or social variables (e.g. the size of an organism relative to other members of its population). Surprisingly, sex-determination mechanisms are not evolutionarily conserved but are bewilderingly diverse and appear to have had rapid turnover rates during evolution. Evolutionary biologists continue to seek a solution to this conundrum. What drives the surprising dynamics of such a fundamental process that always leads to the same outcome: two sex types, male and female? The answer is complex but the ongoing genomic revolution has already greatly increased our knowledge of sex-determination systems and sex chromosomes in recent years. This novel book presents and synthesizes our current understanding, and clearly shows that sex-determination evolution will remain a dynamic field of future research. The Evolution of Sex Determination is an advanced, research level text suitable for graduate students and researchers in genetics, developmental biology, and evolution.
Brian Skyrms presents eighteen essays which apply adaptive dynamics (of cultural evolution and individual learning) to social theory. Altruism, spite, fairness, trust, division of labor, and signaling are treated from this perspective. Correlation is seen to be of fundamental importance. Interactions with neighbors in space, on static networks, and on co-evolving dynamics networks are investigated. Spontaneous emergence of social structure and of signaling systems are examined in the context of learning dynamics.
Studies of evolution at the molecular level have experienced phenomenal growth in the last few decades, due to rapid accumulation of genetic sequence data, improved computer hardware and software, and the development of sophisticated analytical methods. The flood of genomic data has generated an acute need for powerful statistical methods and efficient computational algorithms to enable their effective analysis and interpretation. Molecular Evolution: a statistical approach presents and explains modern statistical methods and computational algorithms for the comparative analysis of genetic sequence data in the fields of molecular evolution, molecular phylogenetics, statistical phylogeography, and comparative genomics. Written by an expert in the field, the book emphasizes conceptual understanding rather than mathematical proofs. The text is enlivened with numerous examples of real data analysis and numerical calculations to illustrate the theory, in addition to the working problems at the end of each chapter. The coverage of maximum likelihood and Bayesian methods are in particular up-to-date, comprehensive, and authoritative. This advanced textbook is aimed at graduate level students and professional researchers (both empiricists and theoreticians) in the fields of bioinformatics and computational biology, statistical genomics, evolutionary biology, molecular systematics, and population genetics. It will also be of relevance and use to a wider audience of applied statisticians, mathematicians, and computer scientists working in computational biology.
Is it possible to explain and predict the development of living things? What is development? Articulate answers to these seemingly innocuous questions are far from straightforward. To date, no systematic, targeted effort has been made to construct a unifying theory of development. This novel work offers a unique exploration of the foundations of ontogeny by asking how the development of living things should be understood. It explores the key concepts of developmental biology, asks whether general principles of development can be discovered, and examines the role of models and theories. The two editors (one a biologist with long interest in the theoretical aspects of his discipline, the other a philosopher of science who has mainly worked on biological systems) have assembled a team of leading contributors who are representative of the scientific and philosophical community within which a diversity of thoughts are growing, and out of which a theory of development may eventually emerge. They analyse a wealth of approaches to concepts, models and theories of development, such as gene regulatory networks, accounts based on systems biology and on physics of soft matter, the different articulations of evolution and development, symbiont-induced development, as well as the widely discussed concepts of positional information and morphogenetic field, the idea of a 'programme' of development and its critiques, and the long-standing opposition between preformationist and epigenetic conceptions of development. Towards a Theory of Development is primarily aimed at students and researchers in the fields of 'evo-devo', developmental biology, theoretical biology, systems biology, biophysics, and the philosophy of science.

In the mid- to late-twentieth century, large scientific conflicts flared in two seemingly distinct fields of scientific inquiry. In bioenergetics, which examines how organisms obtain and utilize energy, the chemiosmotic hypothesis of Mitchell suggested a novel mechanism for energy conversion. In evolutionary biology, meanwhile, Wynne Edwards strongly articulated the view that organisms may act for the "good of the group." This work crystalized a long history of imprecise thinking about the evolution of cooperation. While both controversies have received ample attention, no one has ever suggested that one might inform the other, i.e., that energy metabolism in general and chemiosmosis in particular might be relevant to the evolution of cooperation. The central idea is nevertheless remarkably simple. Chemiosmosis rapidly converts energy, and once storage capacity is exceeded, an overabundance of product has various negative consequences. While to some extent chemiosmotic processes can be modulated, under certain circumstances it is also possible to simply disperse the products into the environment. This book argues that these two heretofore distinct scientific disciplines are connected, thereby suggesting that a ubiquitous process of energy conversion may underlie the evolution of cooperation and link major transitions in the history of life that have been regarded as mechanistically unrelated.
Information is a core concept in animal communication: individuals routinely produce, acquire, process and store information, which provides the basis for their social life. This book focuses on how animal acoustic signals code information and how this coding can be shaped by various environmental and social constraints. Taking birds and mammals, including humans, as models, the authors explore such topics as communication strategies for "public" and "private" signaling, static and dynamic signaling, the diversity of coded information and the way information is decoded by the receiver. The book appeals to a wide audience, ranging from bioacousticians, ethologists and ecologists to evolutionary biologists. Intended for students and researchers alike, it promotes the idea that Shannon and Weaver's Mathematical Theory of Communication still represents a strong framework for understanding all aspects of the communication process, including its dynamic dimensions.
Chronic diseases have rapidly become the leading global cause of morbidity and mortality, yet there is poor understanding of this transition, or why particular social and ethnic groups are especially susceptible. In this book, Wells adopts a multidisciplinary approach to human nutrition, emphasising how power relations shape the physiological pathways to obesity, diabetes, hypertension and cardiovascular disease. Part I reviews the physiological basis of chronic diseases, presenting a 'capacity-load' model that integrates the nutritional contributions of developmental experience and adult lifestyle. Part II presents an evolutionary perspective on the sensitivity of human metabolism to ecological stresses, highlighting how social hierarchy impacts metabolism on an intergenerational timescale. Part III reviews how nutrition has changed over time, as societies evolved and coalesced towards a single global economic system. Part IV integrates these physiological, evolutionary and politico-economic perspectives in a unifying framework, to deepen our understanding of the societal basis of metabolic ill-health.
The concept of the social brain has become a popular topic in the last decade and has generated interest within the research community and contributed to a wide public examination of human culture, nature, mind, and instinct, as well as aspects of social and business organisation. At its core, the hypothesis that our social life drove the dramatic enlargement of our brain, bridges the dimensions of our evolutionary history and our contemporary experience. This has been the focus of a seven-year research project funded by the British Academy, the British Academy Centenary Research Project (otherwise known as the Lucy Project). The main aim of the Lucy Project has been to explore these two axes in an integrated set of studies whose focus was to link archaeology and, in its broadest sense, evolutionary psychology, which offers powerful, new explanatory insights. This approach redresses the past contribution from archaeology towards the study of evolutionary issues and ties evolutionary psychology into the extensive historical data from the past, allowing us to escape the confined timeframe of the comparatively recent human mind. In this volume of published and new papers, the contributors explore the question of just what it is that makes us so different, and why and when these uniquely human capacities evolved.
Both natural and cultural selection played an important role in shaping human evolution. Since cultural change can itself be regarded as evolutionary, a process of gene-culture coevolution is operative. The study of human evolution - in past, present and future - is therefore not restricted to biology. An inclusive comprehension of human evolution relies on integrating insights about cultural, economic and technological evolution with relevant elements of evolutionary biology. In addition, proximate causes and effects of cultures need to be added to the picture - issues which are at the forefront of social sciences like anthropology, economics, geography and innovation studies. This book highlights discussions on the many topics to which such generalised evolutionary thought has been applied: the arts, the brain, climate change, cooking, criminality, environmental problems, futurism, gender issues, group processes, humour, industrial dynamics, institutions, languages, medicine, music, psychology, public policy, religion, sex, sociality and sports. |
