Download or read book Lost Anatomies written by John Gurche and published by Abrams. This book was released on 2019-03-12 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renowned paleoartist John Gurche brings the traditional techniques of figure drawing and anatomical art to the portrayal of our hominin ancestors. The result is a visual record of the evolving human form that feels alive in a way no scientific illustration could match. While science provides an underpinning to Gurche’s art, his work’s primary purpose is to forge an aesthetic connection to the hominins that preceded us on Earth, capturing their humanity. With essays by leading authorities, Lost Anatomies carries the story of human evolution from apes and early hominins; to Australopithecus; to archaic Homo sapiens, including Homo erectus; to derived Homo sapiens, including Neanderthals and other species that are our most recent ancestors.
Download or read book The Ghosts Of Evolution written by Connie Barlow and published by Basic Books. This book was released on 2008-08-05 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new vision is sweeping through ecological science: The dense web of dependencies that makes up an ecosystem has gained an added dimension-the dimension of time. Every field, forest, and park is full of living organisms adapted for relationships with creatures that are now extinct. In a vivid narrative, Connie Barlow shows how the idea of "missing partners" in nature evolved from isolated, curious examples into an idea that is transforming how ecologists understand the entire flora and fauna of the Americas. This fascinating book will enrich and deepen the experience of anyone who enjoys a stroll through the woods or even down an urban sidewalk. But this knowledge has a dark side too: Barlow's "ghost stories" teach us that the ripples of biodiversity loss around us now are just the leading edge of what may well become perilous cascades of extinction.
Download or read book Developmental Plasticity and Evolution written by Mary Jane West-Eberhard and published by Oxford University Press. This book was released on 2003-03-13 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive synthesis on development and evolution: it applies to all aspects of development, at all levels of organization and in all organisms, taking advantage of modern findings on behavior, genetics, endocrinology, molecular biology, evolutionary theory and phylogenetics to show the connections between developmental mechanisms and evolutionary change. This book solves key problems that have impeded a definitive synthesis in the past. It uses new concepts and specific examples to show how to relate environmentally sensitive development to the genetic theory of adaptive evolution and to explain major patterns of change. In this book development includes not only embryology and the ontogeny of morphology, sometimes portrayed inadequately as governed by "regulatory genes," but also behavioral development and physiological adaptation, where plasticity is mediated by genetically complex mechanisms like hormones and learning. The book shows how the universal qualities of phenotypes--modular organization and plasticity--facilitate both integration and change. Here you will learn why it is wrong to describe organisms as genetically programmed; why environmental induction is likely to be more important in evolution than random mutation; and why it is crucial to consider both selection and developmental mechanism in explanations of adaptive evolution. This book satisfies the need for a truly general book on development, plasticity and evolution that applies to living organisms in all of their life stages and environments. Using an immense compendium of examples on many kinds of organisms, from viruses and bacteria to higher plants and animals, it shows how the phenotype is reorganized during evolution to produce novelties, and how alternative phenotypes occupy a pivotal role as a phase of evolution that fosters diversification and speeds change. The arguments of this book call for a new view of the major themes of evolutionary biology, as shown in chapters on gradualism, homology, environmental induction, speciation, radiation, macroevolution, punctuation, and the maintenance of sex. No other treatment of development and evolution since Darwin's offers such a comprehensive and critical discussion of the relevant issues. Developmental Plasticity and Evolution is designed for biologists interested in the development and evolution of behavior, life-history patterns, ecology, physiology, morphology and speciation. It will also appeal to evolutionary paleontologists, anthropologists, psychologists, and teachers of general biology.

Download or read book Physics of Binary Star Evolution written by Thomas M Tauris and published by Princeton University Press. This book was released on 2023-06-20 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: A graduate-level textbook on the astrophysics of binary star systems and their evolution Physics of Binary Star Evolution is an up-to-date textbook on the astrophysics and evolution of binary star systems. Theoretical astrophysicists Thomas Tauris and Edward van den Heuvel cover a wide range of phenomena and processes, including mass transfer and ejection, common envelopes, novae and supernovae, X-ray binaries, millisecond radio pulsars, and gravitational wave (GW) sources, and their links to stellar evolution. The authors walk through the observed properties and evolution of different types of binaries, with special emphasis on those containing compact objects (neutron stars, black holes, and white dwarfs). Attention is given to the formation mechanisms of GW sources—merging double neutron stars and black holes as well as ultra-compact GW binaries hosting white dwarfs—and to the progenitors of these sources and how they are observed with radio telescopes, X-ray satellites, and GW detectors (LIGO, Virgo, KAGRA, Einstein Telescope, Cosmic Explorer, and LISA). Supported by illustrations, equations, and exercises, Physics of Binary Star Evolution combines theory and observations to guide readers through the wonders of a field that will play a central role in modern astrophysics for decades to come. 465 equations, 47 tables, and 350+ figures More than 80 exercises (analytical, numerical, and computational) Over 2,500 extensive, up-to-date references
Download or read book The Evolution of Adaptive Systems written by James Patrick Brock and published by Elsevier. This book was released on 2000-07-12 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: The data of evolutionary biology have changed in a very radical way in recent years, the most significant input to this revolution being the advances made in developmental genetics. Another recent development is a noticeable shift away from extreme specialization in evolutionary biology. In this, we are perhaps to be reminded of George Gaylord Simpson's comments: "evolution is an incredibly complex but at the same time integrated and unitary process." The main objective of this book is to illustrate how natural adaptive systems evolve as a unity--with the particular objective of identifying and merging several special theories of evolution within the framework of a single general theory. The Evolution of Adaptive Systems provides an interdisciplinary overview of the general theory of evolution from the standpoint of the dynamic behavior of natural adaptive systems. The approach leads to a radically new fusion of the diverse disciplines of evolutionary biology, serving to resolve the considerable degree of conflict existing between different schools of contemporary thought. The book is a timely volume written by a natural historian with a broad view of biology The author draws examples from a large range of organisms from many different habitats and niches where interesting adaptations have evolved Probes deeply into mechanisms of evolution such as developmental genetics, morphogenesis, chromosome structure, and cladogenesis Clear definition of terms, with illustrations visualizing the main theoretical structures, and point-by-point summaries clearly stating the principal conclusions
Download or read book Structure and Evolution of Single and Binary Stars written by C. de Loore and published by Springer Science & Business Media. This book was released on 1992-05-31 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical stellar evolution theories have undergone some drastic changes in recent decades. New insights into the development of stellar interiors were obtained from studying stars in various stages of their lives, as well as with the help of fast computers, which gave a boost to the branch of numerical modelling of stellular structure and evolution. This book is divided into two parts. The first part deals with the general aspects of stellular structure and evolution including a chapter on numerical modelling. The second part deals with specific evolutionary aspects of single and binary stars with a variety of masses. The last chapter gives several models of stars with specific masses. The book is intended as an introduction for students, as well as a reference for researchers.
Download or read book Biochemical Evolution written by Bozzano G Luisa and published by Elsevier. This book was released on 2012-12-02 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochemical Evolution focuses on the processes, approaches, and methodologies involved in biochemical evolution, including biochemical systems, digestion, metabolism, and morphology. The publication first offers information on the unity of the biochemical plan of animals, dissimilarities, and evolution of biochemical constituents, as well as biochemical analogs and homologs and evolution of biochemical constituents. The text then ponders on orthogenetic evolution of biochemical systems and biochemical adaptations. Discussions focus on respiratory function, hydrolytic processes of digestion, protein metabolism, ammonemia, domain of glucemia, and marine, fresh-water, and terrestrial animals. The manuscript takes a look at systematic characters, including the biochemical characteristics of vertebrates, tunicates, cyclostomes, elasmobranchs, insects, sipunculids, and the taxonomy of biochemical characteristics. The text then tackles perspectives, as well as mechanism of biochemical evolution, biochemistry and morphology, and irreversibility of lost biochemical characters. The book is a dependable source of data for readers interested in biochemical evolution.

Download or read book Evolution of the Vertebrate Ear written by Jennifer A. Clack and published by Springer. This book was released on 2016-12-21 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of vertebrate hearing is of considerable interest in the hearing community. However, there has never been a volume that has focused on the paleontological evidence for the evolution of hearing and the ear, especially from the perspective of some of the leading paleontologists and evolutionary biologists in the world. Thus, this volume is totally unique, and takes a perspective that has never been taken before. It brings to the fore some of the most recent discoveries among fossil taxa, which have demonstrated the sort of detailed information that can be derived from the fossil record, illuminating the evolutionary pathways this sensory system has taken and the diversity it had achieved.
Download or read book The Evolution of Parental Care written by Mathias Kölliker and published by OUP Oxford. This book was released on 2012-08-09 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parental care includes a wide variety of traits that enhance offspring development and survival. It is taxonomically widespread and is central to the maintenance of biodiversity through its close association with other phenomena such as sexual selection, life-history evolution, sex allocation, sociality, cooperation and conflict, growth and development, genetic architecture, and phenotypic plasticity. This novel book provides a fresh perspective on the study of the evolution of parental care based on contributions from some of the top researchers in the field. It provides evidence that the dynamic nature of family interactions, and particularly the potential for co-evolution among family members, has contributed to the great diversity of forms of parental care and life-histories across as well as within taxa. The Evolution of Parental Care aims to stimulate students and researchers alike to pursue exciting new directions in this fascinating and important area of behavioural and evolutionary biology. It will be of relevance and use to those working in the fields of animal behaviour, ecology, evolution, and genetics, as well as related disciplines such as psychology and sociology.
Download or read book Conceptualizing Evolution Education written by Shala Barczewska and published by Cambridge Scholars Publishing. This book was released on 2017-06-20 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores the benefits of grounding corpus-assisted discourse analysis within the theoretical framework of cognitive linguistics. This is accomplished here against the highly emotive controversy over the teaching of evolution in the US classroom. The book explores grammatical construal, conceptual metaphor theory, conceptual blending theory, frame semantics, and key word analysis, and uses a combination of corpus-based analysis and in-depth manual analysis of select articles. As such, it provides both a broad picture of the way the debate is conceptualized in the US press, as well as a close-up of some of the more representative discourses. This research will be of interest to scholars in a variety of fields including corpus linguistics, cognitive linguistics, discourse analysis, communication studies and American culture, as well as anyone interested in the debate over evolution education.

Download or read book Microbial Evolution under Extreme Conditions written by Corien Bakermans and published by Walter de Gruyter GmbH & Co KG. This book was released on 2015-03-10 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's microorganisms represent the vast majority of biodiversity on Earth and have survived nearly 4 billion years of evolutionary change. However, we still know little about the processes of evolution as applied to microorganisms and microbial populations. Microbial evolution occurred and continues to take place in a vast variety of environmental conditions that range from anoxic to oxic, from hot to cold, from free-living to symbiotic, etc. Some of these physicochemical conditions are considered "extreme", particularly when inhabitants are limited to microorganisms. It is easy to imagine that microbial life in extreme environments is somehow more constrained and perhaps subjected to different evolutionary pressures. But what do we actually know about microbial evolution under extreme conditions and how can we apply that knowledge to other conditions? Appealingly, extreme environments with their relatively limited numbers of inhabitants can serve as good model systems for the study of evolutionary processes. A look at the microbial inhabitants of today's extreme environments provides a snapshot in time of evolution and adaptation to extreme conditions. These adaptations manifest at different levels from established communities and species to genome content and changes in specific genes that result in altered function or gene expression. But as a recent (2011) report from the American Academy of Microbiology observes: "A complex issue in the study of microbial evolution is unraveling the process of evolution from that of adaptation. In many cases, microbes have the capacity to adapt to various environmental changes by changing gene expression or community composition as opposed to having to evolve entirely new capabilities." We have learned much about how microbes are adapted to extreme conditions but relatively little is known about these adaptations evolved. How did the different processes of evolution such as mutation, immigration, horizontal (lateral) gene transfer, recombination, hybridization, genetic drift, fixation, positive and negative selection, and selective screens contribute to the evolution of these genes, genomes, microbial species, communities, and functions? What are typical rates of these processes? How prevalent are each of these processes under different conditions? This book explores the current state of knowledge about microbial evolution under extreme conditions and addresses the following questions: What is known about the processes of microbial evolution (mechanisms, rates, etc.) under extreme conditions? Can this knowledge be applied to other systems and what is the broader relevance? What remains unknown and requires future research? These questions will be addressed from several perspectives including different extreme environments, specific organisms, and specific evolutionary processes.
Download or read book The Evolution of the Global Terrorist Threat written by Bruce Hoffman and published by Columbia University Press. This book was released on 2014-10-28 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examining major terrorist acts and campaigns undertaken in the decade following September 11, 2001, internationally recognized scholars study the involvement of global terrorist leaders and organizations in these incidents and the planning, organization, execution, recruitment, and training that went into them. Their work captures the changing character of al-Qaeda and its affiliates since the invasions of Afghanistan and Iraq and the sophisticated elements that, despite the West's best counterterrorism efforts, continue to exert substantial direction over jihadist terrorist operations. Through case studies of terrorist acts and offensives occurring both in and outside the West, the volume's contributors investigate al-Qaeda and other related entities as they adapted to the strategies of Operation Enduring Freedom and subsequent U.S.-led global counterterrorism programs. They explore whether Osama bin Laden was indeed reduced to a mere figurehead before his death or continued to influence al-Qaeda's global activities. Did al-Qaeda become a loose collection of individuals and ideas following its expulsion from Afghanistan, or was it reborn as a transnational terrorist structure powered by a well-articulated ideology? What is the preeminent terrorist threat we face today, and what will it look like in the future? This anthology pinpoints the critical patterns and strategies that will inform counterterrorism in the coming decades.
Download or read book Evolution in the Dark written by Horst Wilkens and published by Springer. This book was released on 2017-05-25 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides fascinating insights into the development and genetics of evolutionary processes on the basis of animals living in the dark, such as the Astyanax cave fish. Biologically functionless traits show high variability, which results from neutral deleterious mutations no longer being eliminated by natural selection, which normally acts to preserve functional capability. These negative mutations accumulate until the traits they are responsible for become rudimentary or even lost. The random genetic basis of regressive evolution is in accordance with Nei’s Neutral Theory of Molecular Evolution, which applies to the molecular level. Such processes are particularly conspicuous in species living in constant darkness, where, for example in Astyanax, all traits depending on the exposure to light, like eyes, pigmentation, visually triggered aggressive behaviour, negative phototaxis, and several peripheral outcomes of circadian rhythmicity, are useless and diminish. In compensation constructive traits like taste, olfaction or the lateral line senses are improved by selection and do not show variability. Regressive and constructive traits inherit independently, proving that the rudimentation process is not driven by pleiotropic linkage between them. All these traits are subject to mosaic evolution and exhibit unproportional epistatic gene effects, which play an important role in evolutionary adaptation and improvement. Offering valuable evolutionary insights and supplemented by a wealth of illustrations, this book will appeal to evolutionary and developmental biologists alike.
