Controversy over human evolution remains widespread. However, the human genome project and genetic sequencing of many other species have provided myriad precise and unambiguous genetic markers that establish our evolutionary relationships with other mammals. Human Evolution: Genes, Genealogies and Phylogenies identifies and explains these identifiable, rare and complex markers including endogenous retroviruses, genome-modifying transposable elements, gene-disabling mutations, segmental duplications and gene-enabling mutations. The new genetic tools also provide fascinating insights into when and how many features of human biology arose: from aspects of placental structure, vitamin C dependence and trichromatic vision, to tendencies to gout, cardiovascular disease and cancer. Bringing together a decade's worth of research and tying it together to provide an overwhelming argument for the mammalian ancestry of the human species, the book will be of interest to professional scientists and students in both the biological and biomedical sciences.
This book represents a cutting-edge contribution giving an all-around perspective of eco-immunology today. Beside questions of the utmost importance for the whole community of immunologists, e.g, the intrinsic limits of immunological experiments performed at the bench on a limited number of selected models, the book covers several other facets of the eco-immunological approach, including host-parasite interactions, human aging and population immunology. Throughout the book the importance of population dynamics and evolutionary diversification of immune systems is frequently recalled, and makes the reader aware of the basic similarities and differences existing between humans and the models adopted for studying human immune system. The evidenced differences have been recently challenging the reliability of several established animal models and in the book it is discussed for the first time in analytical terms whether mice are reliable models of human inflammatory disorders.
Species are not functionally independent. From a long-term perspective, only ecosystem with a fully integrated nutrient cycle is alive. The lack of trophic autonomy should be considered one of the key factors that ensure and maintain biodiversity. The variability of abiotic conditions, both in space and in time, also creates a huge diversity of niches and subniches for genotypes and species. In addition, life maintains its essential variables (biomass and productivity) as stable as possible due to the diversity of structures (genes, macromolecules, metabolic pathways, genotypes, species, etc.): the structures that reach optima are multiplied and thus activated, while the functioning of those which lost their optima is suppressed. The facts and concepts presented in this monograph thus support the conclusions that (a) genotype and species diversity is supported by trophic specialisation (b) biodiversity helps to stabilise the functions (essential variables) of individuals, populations, and ecological communities (c) in evolution, the emergence of biodiversity is determined by heritable variation and the advantage of specialised (more effective) structures over non-specialised ones (d) biodiversity is characterised by its ability to increase itself and to organise itself into relatively consistent structures, which we call production pyramids and nutrient cycles. This book therefore provides an answer to the question "why the diversity of life is of such and such a nature".
The Anthropocene is the "age of human influence", an epoch well known for its urban impact. More than half of all people already live in cities, and this proportion is expected to rise to almost 70 percent by 2050. Like other species in urban areas, bats must contend with the pressures of profound and irreversible land cover change and overcome certain unique challenges, such as the high density of roads, lights, glass, and free-ranging domestic animals. Research on urban bats in recent decades indicates that when it comes to urban life, some bats are synanthropes. In other words, although most species of bats are negatively impacted by urbanisation, many appear to not only succeed, but also thrive in cities and towns. This observation has inspired interesting questions about bats in relation to urbanisation. Which traits and behaviours equip bats for urban success? What features of urban areas increase the likelihood that bats will successfully persist there or even colonize new areas? And how does the success of urban bats affect co-habiting humans? Our book explores the interactions between bats and urban environments through case studies and reviews. Understanding how different species interact with urban environments can reveal potential opportunities to mitigate urban threats to bats and threats posed by bats to other urban organisms, including humans. With this book, we thus aspire to provide a knowledge base to help guide current and future efforts to conserve bats.
RNA viruses provide unique insights into the patterns and processes of evolutionary change in real time. The study of viral evolution is especially topical given the growing awareness that emerging and re-emerging diseases (most of which are caused by RNA viruses) represent a major threat to public health. However, while the study of viral evolution has developed rapidly in the last 30 years, relatively little attention has been directed toward linking work on the mechanisms of viral evolution within cells or individual hosts, to the epidemiological outcomes of these processes. This novel book fills this gap by considering the patterns and processes of viral evolution across their entire range of spatial and temporal scales. The Evolution and Emergence of RNA Viruses provides a comprehensive overview of RNA virus evolution, with a particular focus on genomic and phylogenetic approaches. This is the first book to link mechanisms of viral evolution with disease dynamics, using high-profile examples in emergence and evolution such as influenza, HIV, dengue fever, and rabies. It also reveals the underlying evolutionary processes by which emerging viruses cross species boundaries and spread in new hosts.
When I first proposed a series entitled Current Mammalogy to the pub lishers, they were reluctant to undertake such a project because they viewed the field of mammology as overly fragmented. At first I found this idea to be difficult to accept; however, upon reflection, I came near to agreeing with it. Although many of us work on mammals, we gen erally feel more allegiance to our specialties, such as systematics, ge netics, cytogenetics, ecology, behavior, pest control, paleontology, wildlife management, primatology, and marine mammalogy, than we do to the general field of mammalogy. However, rather than becoming discour aged from pursuing this project, I became more certain than ever that a series such as Current Mammalogy was needed. We hope to make this series a place where specialists can present their ideas not only to other members of their specialty, but to those outside the area as well. Hopefully, this exchange of ideas will be a mutually beneficial exercise. The Editorial Board of Current Mammalogy has decided to keep the range of subjects in each volume as broad as possible rather than concentrating on one or two topics, in the hope that this will keep the series as useful as possible to the broadest range of readers."
New material attributable to Deltasuchus motherali, a neosuchian from the Cenomanian of Texas, provides sampling across much of the ontogeny of this species. Detailed descriptions provide information about the paleobiology of this species, particularly with regards to how growth and development affected diet. Overall snout shape became progressively wider and more robust with age, suggesting that dietary shifts from juvenile to adult were not only a matter of size change, but of functional performance as well. These newly described elements provide additional characters upon which to base more robust phylogenetic analyses. The authors provide a revised diagnosis of this species, describing the new material and discussing incidents of apparent ontogenetic variation across the sampled population. The results of the ensuing phylogenetic analyses both situate Deltasuchus within an endemic clade of Appalachian crocodyliforms, separate and diagnosable from goniopholidids and pholidosaurs, herein referred to as Paluxysuchidae. This title is also available as Open Access on Cambridge Core.
Cellular-molecular approach to evolution has led to radical changes in our understanding of biologic principles ranging from the Cell, to the Life Cycle, Development, Homeostasis, Senescence/Aging, Heterochrony, Pleiotropy, Phenotype, and perhaps the purpose of life itself. Much of this new way of thinking about biology and medicine emanates from experimental evidence for epigenetic inheritance. This leads one to question whether our unicellular state is the actual primary level of selection. One particular system that is now recognized as being under the auspices of epigenetic inheritance is the endocrine system, which is conventionally thought to regulate physiologic homeostasis. However, because the sex hormones play such a major role in behaviors related to the acquisition of epigenetic data, and the processing of such epigenetic data by the gonads during meiosis, their role in the evolution of the organism become tractable. The composite of the activities of the individual over the course of its lifetime can now be understood causally, resulting from the orchestration of its physiology by hormones, prenatally, postnatally and during the aging process, across the entire life span of the organism. Specific behaviors over the course of the life cycle during childhood, adolescence, puberty, adulthood and aging can now be understood mechanistically rather than merely as milestones in the various stages of life. With the above considerations in mind, this book presents the cellular-evolutionary perspective towards the relationship of the organism with its surroundings, human and non-human alike renders biology and medicine a continuum instead of fragmented, un-related anecdotes.
Charles Darwin's "Historical Sketch" has appeared as a preface to nearly every authorized edition of Darwin's Origin of Species since the second English edition was published in 1860. The "Historical Sketch" provides a brief history of opinion about the species question as a prelude to Darwin's own independent contribution to the subject, but its provenance is somewhat obscure. While some previous thinkers anticipated portions of Darwin's theory long before he did, none of them saw the complete picture as clearly as Darwin. As such, he was able to claim originality and priority for the idea that has transformed our understanding of nature. His "Historical Sketch" was written as an attempt to address these issues. Some things are known about its production, such as when it first appeared and what changes were made to it between its first appearance in 1860 and its final form in 1866. Other questions remain unanswered. How did it evolve in Darwin's mind? Why did he write it at all? What did he think he was accomplishing by prefacing it to Origin of Species? Curtis Johnson approaches these questions, offering some clarity on the originality of Darwin's work. Darwin's "Historical Sketch" is the first comprehensive study of Darwin's "Preface" to Origin of Species. Johnson conveys the pressure Darwin felt from friends and other correspondents to showcase the originality of his theory, and he tackles questions of originality by carefully examining the 35 authors Darwin referenced in this monumental text.
Widely seen as evolution's founding figure, Charles Darwin is taken by many evolutionists to be the first to propose a truly modern theory of evolution. Darwin's greatness, however, has obscured the man and his work, at times even to the point of distortion. Accessibly written, this book presents a more nuanced picture and invites us to discover some neglected ambiguities and contradictions in Darwin's masterwork. Delisle and Tierney show Darwin to be a man who struggled to reconcile the received wisdom of an unchanging natural world with his new ideas about evolution. Arguing that Darwin was unable to break free entirely from his contemporaries' more traditional outlook, they show his theory to be a fascinating compromise between old and new. Rediscovering this other Darwin - and this other side of On the Origin of Species - helps shed new light on the immensity of the task that lay before 19th century scholars, as well as their ultimate achievements.
This book answers the question "What is it that viruses do?" by presenting three aspects of viral ecology. The first aspect explains how viruses affect the population diversity and energetics of their host communities. Perhaps the most notable example of this concept is our understanding that primary production within ecosystems often depends upon those viruses which serve as controllers of nutrient recycling, connecting the aquatic and terrestrial realms in ways that can be assessed locally and globally. The second aspect describes genetic partnerships which exist between hosts and their viruses. These include processes termed endogeny and lysogeny by which the host carries at least a partial genomic copy of the virus. Fluidity of these collective genomes is expressed on an evolutionary time scale and the mutual life cycles which they produce represent a forging of shared genomic fate that obligates partnership of the virus and its host. The viral sequences represent a source of potential benefit as well as potential peril for the host and can implement phenotypic changes in the host. Hosts often use those changes as tools. As humans, the most notable example would be that mammals rely upon temporary activation of their endogenous viral genes in order to successfully develop a placenta. The third aspect is defending the health of a host, which relies upon activity in two directions. Hosts often use their captured viral genes to identify and subsequently direct battle against invading viruses. This natural concept has been engineered for combating cancer, is useful for suppressing the detrimental consequences of genetic diseases, and has been developed to create targeted antiviral vaccines. But, the defense has to work in two directions and the host can use other symbiotic microorganisms as protection against its viruses. This book will appeal to a wide readership by providing a broad perspective of viral ecology, and all scientists will find it helpful for gaining a view of fields beyond their specialization.
The epistemological synthesis of the various theories of evolution, since the first formulation in 1802 with the transmission of the inherited characters by J.B. Lamarck, shows the need for an alternative synthesis to that of Princeton (1947). This new synthesis integrates the scientific models of self-organization developed during the second half of the 20th century based on the laws of physics, thermodynamics, and mathematics with the emergent evolutionary problematics such as self-organized memory. This book shows, how self-organization is integrated in modern evolutionary biology. It is divided in two parts: The first part pays attention to the modern observations in paleontology and biology, which include major theoreticians of the self-organization (d'Arcy Thompson, Henri Bergson, Rene Thom, Ilya Prigogine). The second part presents different emergent evolutionary models including the sciences of complexity, the non-linear dynamical systems, fractals, attractors, epigenesis, systemics, and mesology with different examples of the sciences of complexity and self-organization as observed in the human lineage, from both internal (embryogenesis-morphogenesis) and external (mesology) viewpoints.
The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.

the history and philosophy of Darwinism.
The four volumes of Game Equilibrium Models present applications of non-cooperative game theory. Problems of strategic interaction arising in biology, economics, political science and the social sciences in general are treated in 42 papers on a wide variety of subjects. Internationally known authors with backgrounds in various disciplines have contributed original research. The reader finds innovative modelling combined with advanced methods of analysis. The four volumes are the outcome of a research year at the Center for Interdisciplinary Studies of the University of Bielefeld. The close interaction of an international interdisciplinary group of researchers has produced an unusual collection of remarkable results of great interes for everybody who wants to be informed on the scope, potential, and future direction of work in applied game theory. Volume I Evolution and Game Dynamics mainly deals with dynamic stability with respect to evolutionary processes. The book offers not only theoretical classification of the foundations of evolutionary game theory, but also exciting new biological applications. Volume II Methods, Morals and Markets contains areas of research which will attract the interest of economists, political scientists, mathematicians and philosophers. The papers deal with the methodology of analysis of games, game theoretic contributions to fundamental ethical questions facing societies and game-theoretic analyses of market environments. Volume III Strategic Bargaining contains ten papers on game equilibrium models of bargaining. All these contributions look at bargaining situations as non-cooperative games. General models of two-person and n-person bargaining areexplored. Volume IV Social and Political Interaction contains game equilibrium models focussing on social and political interaction within communities or states or between states, i.e. national and international social and political interaction. Specific aspects of those interactions are modelled as non-cooperative games and their equilibria are analysed.
This ambitious book considers social scientific topics such as identity, community, sexual difference, self, and ecology from a microbial perspective. Harnessing research and evidence from earth systems science and microbiology, and particularly focusing on symbiosis and symbiogenesis, the book argues for the development of a microontology of life.
The Wrong Ape for Early Human Origins examines ways in which the chimpanzee referential model has exerted a primary influence on evolutionary theory, dominating portraits of proto- and early human social life, and in the broader sense, of human nature itself. Evidence on which this model is based is revisited, along with new cross-disciplinary findings that point to alternative scenarios for hominin phylogeny, ecology and subsistence, primeval kinship, cognition and language, and the respective roles played by aggression and cooperation as evolutionary drivers. Recent advances in phylogenetics, evolutionary biology, and new additions to the fossil record are rendering linear, monotypic models obsolete. Contemporary theories on species divergence and change over time are shifting attention from ancient genotypes to factors that influence gene expression, and from innate prescriptive behaviors to epigenesis and the capacity for behavioral plasticity. This broader platform has the potential to fundamentally revise current notions about the basic nature, phenotypic traits, and lifeways of ancestral humans. It informs a different profile of our progenitors—one that reflects greater ecological bandwidth, reliance on creative niche construction, and hominin agency in the structuring of ancient reproductive and social groups.
This book introduces the value of a Darwinian social evolutionary approach to understanding social change. The chapters discuss several different perspectives on social evolutionary theory, and go on to link these with comparative and historical sociological theory, and two case-studies. Kerr brings together social change theory and theories on nationalism, whilst also providing concrete examples of the theories at work. The book offers a vision of rapprochement between these different areas of theory and study, and to where this could lead future studies of comparative history and sociology. As such, it should be useful to scholars and students of nationalism and social change, sociologists, political scientist and historians.
Epigenetic modifications comprise heritable gene expression changes that occur without alteration of the DNA sequence and 'co-act' with genetic factors to shape development processes and evolutionary trajectories. Multicellular organisms receive different types of environmental stimuli/stresses that trigger epigenetic modifications during development. These environmentally driven mechanisms represent an underlying cause of phenotypic diversity, especially in metazoans. This book aims to present some of the latest epigenetic insights into the development of metazoans (including humans) as an intersection between their ecology and evolution.
James Mark Baldwin (1861-1934) was one of American psychology's greatest contributors, both professionally and intellectually. Professionally, he founded experimental laboratories at the Universities of Toronto and Princeton, established two important journals: The Psychological Review and The Psychological Bulletin, and served as President of the American Psychological Association. Intellectually, Baldwin was one of the field's most prolific authors and quite possibly its most sophisticated thinker. Over the course of his career, he published twenty-two books and approximately one-hundred-fifty articles. Among his publications were the field's first well-controlled experimental studies of infant behavior and a work, Social and Ethical Interpretations in Mental Development. Between 1901 and 1905 he edited a three volume Dictionary of Philosophy and Psychology that is still one of the best sources for turn-of-the-century thought in these disciplines. This led directly to his receiving Oxford University's first honorary doctorate of science. Baldwin's biosocial approach introduced a level of complexity in conceptualization of the mind, its evolutionary origins, ontogenetic development, and sociocultural formation that went far beyond the prevailing thought of the period. He addressed topics as varied as the nature of developmental and evolutionary mechanisms, the relationship between reason and reality, the genesis of logic, the value of aesthetic experience, and the nature and development in children of habit, imitation, creative invention, altruism, egoism, morality, social suggestibility, social self, self-awareness, theory of mind, and enculturation. His use and in some cases introduction of concepts such as multiplicity of self, ideal self, self-esteem, assimilation, accommodation, primary circular reaction, genetic logic, genetic epistemology, and social heredity exerted a formative influence on later scholars such as George Herbert Mead, Jean Piaget, Lev S. Vygotsky, and Lawrence Kohlberg. In Development and Evolution, Baldwin had arrived at a clear conception of the mechanism mediating the influence of individual adaptations on the course of phylogenetic evolution. As he described it in an autobiographical chapter written toward the end of his life, the theory of organic selection involved the claim that: "natural selection operating on "spontaneous variations" is sufficient alone to produce determinate evolution (without the inheritance of acquired adaptations or modifications), since - and this is the new point - in each generation variations in the direction of, or "coincident" with, the function to be developed will favor the organisms possessing them, and their descendants will profit by the accumulation of such variations. Thus the function will gradually come to perfection. In other words, the individual organism's accommodations, made through learning, effort, adaptation, etc., while not physically inherited, still act to supplement or screen the congenital endowment during its incomplete stages, and so give the species time to build up its variations in determinate lines." This title is increasingly heavily cited because of the great interest in how development is represented genetically and how changes in gene expression during development, especially regulatory genes, occur through selection on phenotypes
The richly fossiliferous Neogene stratigraphic sections of the Dominican Republic serve as one of only a few geological research systems in the world where morphological stasis and punctuated speciation have been investigated in multiple lineages. This research system provides unprecedented opportunities for comparative studies of evolutionary stasis and change and their environmental and ecological contexts. In this volume, a diverse group of geologists and paleobiologists collectively focus their attention on this research system, providing an updated geological framework and a series of novel studies of evolutionary stasis and change among different lineages and associated ecological communities. This collection of studies illustrates the immense potential of collaborative, multidisciplinary, and field-based paleobiological research for studies of macroevolutionary change in the fossil record. |
