Evolutionary Genomics and Systems Biology
by Gustavo Caetano-AnollésA comprehensive, authoritative look at an emergent area in post-genomic science, Evolutionary genomics is an up-and-coming, complex field that attempts to explain the biocomplexity of the living world. Evolutionary Genomics and Systems Biology is the first full-length book to blend established and emerging concepts in bioinformatics, evolution, genomics, and structural biology, with the integrative views of network and systems biology.Three key aspects of evolutionary genomics and systems biology are covered in clear detail: the study of genomic history, i.e., understanding organismal evolution at the genomic level; the study of macromolecular complements, which encompasses the evolution of the protein and RNA machinery that propels life; and the evolutionary and dynamic study of wiring diagrams--macromolecular components in interaction--in the context of genomic complements. The book also features:A solid, comprehensive treatment of phylogenomics, the evolution of genomes, and the evolution of biological networks, within the framework of systems biologyA special section on RNA biology--translation, evolution of structure, and micro RNA and regulation of gene expressionChapters on the mapping of genotypes to phenotypes, the role of information in biology, protein architecture and biological function, chromosomal rearrangements, and biological networks and diseaseContributions by leading authorities on each topicEvolutionary Genomics and Systems Biology is an ideal book for students and professionals in genomics, bioinformatics, evolution, structural biology, complexity, origins of life, systematic biology, and organismal diversity, as well as those individuals interested in aspects of biological sciences as they interface with chemistry, physics, and computer science and engineering.
Evolutionary Gerontology and Geriatrics: Why and How We Age (Advances in Studies of Aging and Health #2)
by Giacinto Libertini Graziamaria Corbi Valeria Conti Olga Shubernetskaya Nicola FerraraThis book provides concrete scientific basis that we can conceive the possibility of modifying or even completely canceling aging process, despite the fact that aging is commonly regarded as the result of the overall effects of many uncontrollable degenerative phenomena. The authors illustrate in detail the mechanisms by which cells and the whole organism age. Actions by which it is possible, or will be possible within a limited time, to operate for modifying aging are also debated.The discussion is conducted within the frame and the concepts of evolutionary medicine, which is also indispensable for distinguishing between the manifestations of aging and: (i) diseases that worsen with age, and (ii) acceleration of normal aging rates, caused by unhealthy lifestyle habits and other avoidable factors. The book also discusses the impact of aging on overall mortality and the strange situation that, according to official statistics, aging does not exist as cause of death.This book is a turning point between a gerontology and geriatrics conceived as the study and vain treatment of an incurable condition and one in which these disciplines examine the how and why of a physiological phenomenon that can be modified up to a possible total control. This means transforming the medical prevention and treatment of physiological aging from the greatest failure to the greatest success of medicine.
Evolutionary History
by Edmund RussellWe tend to see history and evolution springing from separate roots, one grounded in the human world and the other in the natural world. Human beings have, however, become probably the most powerful species shaping evolution today, and human-caused evolution in other species has probably been the most important force shaping human history. This book introduces readers to evolutionary history, a new field that unites history and biology to create a fuller understanding of the past than either can produce on its own. Evolutionary history can stimulate surprising new hypotheses for any field of history and evolutionary biology. How many art historians would have guessed that sculpture encouraged the evolution of tuskless elephants? How many biologists would have predicted that human poverty would accelerate animal evolution? How many military historians would have suspected that plant evolution would convert a counter-insurgency strategy into a rebel subsidy? With examples from around the globe, this book will help readers see the broadest patterns of history and the details of their own life in a new light.
Evolutionary History of the Robust Australopithecines
by Frederick E. GrineIn paleoanthropology the group of hominids known as the "robust" australopithecines has emerged as one of the most interesting. Through them we have the opportunity to examine the origin, natural history, and ultimate extinction of not just a single species, but of an entire branch in the hominid fossil record. It is generally agreed that the human lineage can be traced back to this group of comparatively small-brained, large-toothed creatures. This volume focuses on the evolutionary history of these early hominids with state-of-the-art contributions by leading international authorities in the field. Although a case can be made for a "robust" lineage, the functional and taxonomic implications of the morphological features are subject to vigorous disagreement. An area of lively debate is the possible causal relationship between the presence of early Homo and the origin, evolution, and virtual extinction of "robust" australopithecines.This volume summarizes what has been learned about the evolutionary history of the "robust" australopithecines in the 50 years since Robert Broom first encountered the visage of a new kind of ape-man from Kromdraai. New discoveries from Kromdraai to Lomekwi have served to keep us aware that the paleontological record for hominid evolution is hardly exhausted. Because of such finds no single volume can hope to stand as a summary on the "robust" australopithecines for very long, but this classic volume comes close to achieving this goal. The book sheds new light upon some old questions and also acts to provide new questions. The answers to those questions bring us closer to a fuller understanding and appreciation of the origins, evolution, and ultimate demise of the "robust" australopithecines. Since the "robust" australopithecines most likely stand as our closest relatives, a better understanding of their origin, history, and demise serves to provide heightened appreciation of the course of human evolution itself. This definitive volume addresses the questions and problems surrounding this important lineage.
Evolutionary Intelligence: How Technology Will Make Us Smarter
by W. Russell NeumanA surprising vision of how human intelligence will coevolve with digital technology and revolutionize how we think and behave.It is natural for us to fear artificial intelligence. But does Siri really want to kill us? Perhaps we are falling into the trap of projecting human traits onto the machines we might build. In Evolutionary Intelligence, Neuman offers a surprisingly positive vision in which computational intelligence compensates for the well-recognized limits of human judgment, improves decision making, and actually increases our agency. In artful, accessible, and adventurous prose, Neuman takes the reader on an exciting, fast-paced ride, all the while making a convincing case about a revolution in computationally augmented human intelligence.Neuman argues that, just as the wheel made us mobile and machines made us stronger, the migration of artificial intelligence from room-sized computers to laptops to our watches, smart glasses, and even smart contact lenses will transform day-to-day human decision making. If intelligence is the capacity to match means with ends, then augmented intelligence can offer the ability to adapt to changing environments as we face the ultimate challenge of long-term survival.Tapping into a global interest in technology&’s potential impacts on society, economics, and culture, Evolutionary Intelligence demonstrates that our future depends on our ability to computationally compensate for the limitations of a human cognitive system that has only recently graduated from hunting and gathering.
The Evolutionary Mind
by Terence Mckenna Ralph Abraham Rupert SheldrakeStimulating and often startling discussions between three friends, all highly original thinkers: Rupert Sheldrake, controversial biologist, Terence McKenna , psychedelic visionary, and Ralph Abraham , chaos mathematician. Their passion is to break out of paradigms that retard our evolution and to explore new possibilities. Through challenge and synergy they venture where few have gone before, leading their readers on an exciting journey of discovery. Their discussions focus on the evolution of the mind, the role of psychedelics, skepticism, the psychic powers of animals, the structure of time, the life of the heavens, the nature of God, and transformations of consciousness."Three fine thinkers take us plunging into the universe of chaos, mind, and spirit. Instead of leaving us lost, they bring us back with startling insights and more wonder than we knew we had." --Matthew Fox, Original Blessing and Sheer Joy"A jam-session of the mind, an intellectual movable feast, an on-going conversation that began over twenty years ago and remains as lively and relevant today as it ever was. Sadly, Terence had to leave the conversation a little earlier than planned. But the appearance of this book of trialogues at this critical, historical juncture is a reaffirmation of the potency of the optimistic vision that the trialogues express." --Dennis McKenna, brother of the late Terence McKennaRupert Sheldrake is a biologist and author of many books including The Sense of Being Stared At, And Other Aspects of the Extended Mind. Ralph Abraham is a mathematician, one of the pioneers of chaos theory and the author of several books including Chaos, Gaia, Eros: A Chaos Pioneer Uncovers the Three Great Streams of History. The late Terence McKenna was a scholar of shamanism, ethno-botanist, psychedelic researcher and author of many books including Food of the Gods and True Hallucinations.

Evolutionary Origin of Sensory and Neurosecretory Cell Types: Vertebrate Cranial Placodes, volume 2 (Evolutionary Cell Biology)
by Gerhard SchlosserMost vertebrate cranial sense organs arise from placodes. These placodes give rise to sensory neurons that transmit information to the brain and neurosecretory cells. This book reviews the evolutionary origin of the sensory and neurosecretory cell types. It summarizes our current understanding of vertebrate evolution, clarifies conceptual issues relating to homology and evolutionary innovation of cell types, compares the sensory and neurosecretory cell types with similar cell types in other animals, and addresses the question of how cranial placodes evolved as novel structures in vertebrates by redeploying pre-existing and sometimes evolutionarily ancient cell types.
Evolutionary Paleoecology: The Ecological Context of Macroevolutionary Change
by David J. Bottjer Warren AllmonOne of the most important questions we can ask about life is "Does ecology matter?" Most biologists and paleontologists are trained to answer "yes," but the exact mechanisms by which ecology matters in the context of patterns that play out over millions of years have never been entirely clear. This book examines these mechanisms and looks at how ancient environments affected evolution, focusing on long-term macroevolutionary changes as seen in the fossil record. Evolutionary paleoecology is not a new discipline. Beginning with Darwin, researchers have attempted to understand how the environment has affected evolutionary history. But as we learn more about these patterns, the search for a new synthetic view of the evolutionary process that integrates species evolution, ecology, and mass extinctions becomes ever more pressing. The present volume is a benchmark sampler of active research in this ever more active field.P.K. Strother, Choice

Evolutionary Perspectives on Environmental Problems
by Dustin J. Penn Iver Mysterud E. O. WilsonThe twenty-first century presents an increasing number of environmental problems, including toxic pollution, global warming, destruction of tropical forests, extinction of biological diversity, and depletion of natural resources. These environmental problems are generally due to human behavior, namely over-consumption of resources and overpopulation. Designing effective policies to address these problems requires a deep understanding of human behavior as well as ecology. This in turn requires considerations of human nature, and the evolutionary "design" of the human mind.Evolutionary research on human behavior has profound implications for the environmental sciences. The aim of this collection is to bring together a variety of chapters that show how and why. Part 1, "Human Nature and Resource Conservation," addresses environmental problems from different evolutionary perspectives. Part 2, "The Ecological Noble Savage Hypothesis," examines the notion that our environmental problems are due to Western culture, and that our ancestors and people in indigenous societies lived in harmony with nature until the corrupting influences of Western culture. Part 3, "The Tragedy of the Commons," explores the conservation of common-pool or open-access natural resources, such as fisheries, forests, grazing lands, freshwater, and clean air. Part 4, "The Evolution of Discounting and Conspicuous Consumption," looks at the problem of explaining why people are so ecologically short-sighted and why people in developed countries consume so many resources. Part 5, "Overpopulation and Fertility Declines," addresses the evolution of human reproductive decisions. Part 6, "Biophilia," aims to explain why people cherish nature as well as destroy it.The goal of this volume is to introduce environmental thinkers to evolutionary perspectives on human behavior, and the new interdisciplinary sciences of evolutionary psychology and behavioral ecology. This reader aims to help bridge

The text also integrates behavior-genetic research with evolutionary and developmental principles. Evolutionary Perspectives on Human Development provides state-of-the-art groundwork in evolutionary theory as viewed by leading thinkers in the field.
Evolutionary Perspectives on Pregnancy
by John AviseCovering both the internal and external incubation of offspring, this book provides a biology-rich survey of the natural history, ecology, genetics, and evolution of pregnancy-like phenomena. From mammals and other live-bearing organisms to viviparous reptiles, male-pregnant fishes, larval-brooding worms, crabs, sea cucumbers, and corals, the world's various species display pregnancy and other forms of parental devotion in surprisingly multifaceted ways. An adult female (or male) can incubate its offspring in a womb, stomach, mouth, vocal sac, gill chamber, epithelial pouch, backpack, leg pocket, nest, or an encasing of embryos, and by studying these diverse examples from a comparative vantage point, the ecological and evolutionary-genetic outcomes of different reproductive models become fascinatingly clear. John C. Avise discusses each mode of pregnancy and the decipherable genetic signatures it has left on the reproductive structures, physiologies, and innate sexual behaviors of extant species. By considering the many biological aspects of gestation from different evolutionary angles, Avise offers captivating new insights into the significance of "heavy" parental investment in progeny.

Evolutionary Population Genetics of Drosophila ananassae
by Pranveer SinghThis book introduces readers to classical population genetics and the ways in which it can be applied to practical problems, including testing for natural selection, genetic drift, genetic differentiation, population structuring, gene flow and linkage disequilibrium. It provides a comprehensive monograph on the topic, addressing the theory, applications and evolutionary deductions, which are clearly explained using experimental results. It also offers separate chapters on origin, establishment and spread of chromosomal aberrations in populations along with details of culturing, maintaining and using Drosophila ananassae (genetically unique and the most commonly used species along with D. melanogaster) for genetic research. Encompassing topics like genetics, evolution, Drosophila genetics, population genetics, population structuring, natural selection and genetic drift in considerable detail, it provides a valuable resource to undergraduate and postgraduate students, as well as researchers at all level. This book explores some fundamental questions concerning the role of natural selection and genetic drift on the degree of inversion polymorphism. India, with its wide diversity in geo-climatic conditions, provides an excellent platform to conduct such studies. The book showcases sampling records of inversion frequencies in natural Indian populations of D. ananassae that cover more than two decades. It highlights case studies in which sampling data on inversion frequencies was combined with that from earlier surveys, generating a time series that allows the evolutionary dynamics of inversion polymorphism to be explored. Such long time series are rare but nonetheless crucial for studying the evolutionary dynamics of inversion polymorphism. The population-genetic analysis discussed is unprecedented in terms of its temporal (two decades) and spatial (most regions of India covered) scale and investigates the patterns of polymorphic system in D. ananassae to see if there is any temporal divergence. It endeavors to present a holistic picture of inversion polymorphism across the country (India). Chromosomal aberrations, particularly paracentric inversions, are used as a tool for discussing population genetic studies, helping human geneticists, gynecologists and other medical professionals understand why some aberrations are fatal in humans, with affected embryos often not surviving the first trimester of pregnancy, while similar aberrations in Drosophila flies aid in their adaptation to the environmental heterogeneity across the globe.
Evolutionary Processes in the Natural History of Religion: Body, Brain, Belief (New Approaches to the Scientific Study of Religion #10)
by Hansjörg HemmingerThe 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.
Evolutionary Psychology: A Beginner's Guide (Beginner's Guides)
by Louise Barrett Robin Dunbar John LycettStarting with its origins in the work of Charles Darwin, the book covers all the key areas of evolutionary psychology, including the role played by genetics in our sexual behavior, parental decision-making, and how babies learn about and adapt to the world.
Evolutionary Psychology: Volume II (The International Library of Essays on Evolutionary Thought)
by Neil LevyEvolutionary approaches to the study of human beings have been able to explain the origin and maintenance of many of the features of our bodies. Many thinkers believe that an evolutionary approach will be equally fruitful when it comes to explaining the features of our minds. Since our behaviour is driven by our minds, our cognitive dispositions and processes are likely to have been a target of selection and adaptation. This volume collects recent prominent explorations of this theme, as well as the voices of dissenters who argue that our minds are far more significantly the product of culture than of evolution.
Evolutionary Psychology: Neuroscience Perspectives concerning Human Behavior and Experience
by William J. RayMany books in evolutionary psychology emphasize just a small part of the total picture. Evolutionary Psychology gives students a clear understanding of how current psychological knowledge of human behavior and experience draws from a variety of perspectives. It begins with an understanding of evolution and the close connection between organisms and their environment. It provides the student the basics necessary to see how the environment and the turning on and off of genes can influence humans and the cultures in which they live. The book shows that we solve certain problems of life as many species have done for years. It also shows a glimpse of human abilities not seen in other species. We use language. We purposely teach our children. We build large cities that survive long after a single generation. We create cultures that through their writings and art can influence other humans thousands of years later. Current research in social processes, decision making, and brain imaging is presented in a clear manner throughout the book. The book emphasizes developmental processes and family relationships, sexual and social relationships, as well as emotionality and language. The book concludes by applying an evolutionary understanding approach to examine the areas of health and disease, psychopathology, and culture.
Evolutionary Psychology
by Lance Workman Will ReaderEvolutionary psychology starts from the premise that the human brain is the product of natural selection; therefore, by adopting an evolutionary stance, we might come to better understand the mind and behaviour. The second edition of this highly acclaimed textbook gives an introduction to the fascinating science of evolutionary psychology covering its history, from the Ancient Greeks to the present day, and discusses how evolution can illuminate many of the topics taught in psychology departments. This new edition, now in 2 colour, includes an additional chapter on 'Evolution and Individual Differences' which discusses how evolution might account for differences in personality and intelligence. With an engaging style and user-friendly format featuring end-of-chapter summaries, critical thinking questions and guides to further reading, this is a stand-alone textbook for undergraduates studying evolutionary psychology.
Evolutionary Psychology and the Propositional-attitudes
by Alex WalterThe two essays provide a critical examination of theory and research in the field of evolutionary psychology. The view advanced here is that philosophical materialism and minimalist assumptions about adaptation serve Darwinian psychology better than the more popular alternative view that relies on cognitive dualism and propositional-attitude psychology to formulate evolutionary psychology theory. A commitment to cognitive dualism is destined to undermine the physical basis of behavior upon which evolutionary theory depends. Many evolutionary psychologists do not see this but are seduced by the easy way in which hypotheses can be formulated using the 'propositional-attitude' model. The challenge is to develop a materialistic and mechanistic approach to understanding human cognition and behavior, including linguistic and social behavior.
