Download or read book The Century of the Gene written by Evelyn Fox KELLER and published by Harvard University Press. This book was released on 2009-06-30 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a book that promises to change the way we think and talk about genes and genetic determinism, Evelyn Fox Keller, one of our most gifted historians and philosophers of science, provides a powerful, profound analysis of the achievements of genetics and molecular biology in the twentieth century, the century of the gene. Not just a chronicle of biology’s progress from gene to genome in one hundred years, The Century of the Gene also calls our attention to the surprising ways these advances challenge the familiar picture of the gene most of us still entertain. Keller shows us that the very successes that have stirred our imagination have also radically undermined the primacy of the gene—word and object—as the core explanatory concept of heredity and development. She argues that we need a new vocabulary that includes concepts such as robustness, fidelity, and evolvability. But more than a new vocabulary, a new awareness is absolutely crucial: that understanding the components of a system (be they individual genes, proteins, or even molecules) may tell us little about the interactions among these components. With the Human Genome Project nearing its first and most publicized goal, biologists are coming to realize that they have reached not the end of biology but the beginning of a new era. Indeed, Keller predicts that in the new century we will witness another Cambrian era, this time in new forms of biological thought rather than in new forms of biological life.

Download or read book Polyploidy and Genome Evolution written by Pamela Soltis and published by Springer Science & Business Media. This book was released on 2012-10-03 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyploidy – whole-genome duplication (WGD) – is a fundamental driver of biodiversity with significant consequences for genome structure, organization, and evolution. Once considered a speciation process common only in plants, polyploidy is now recognized to have played a major role in the structure, gene content, and evolution of most eukaryotic genomes. In fact, the diversity of eukaryotes seems closely tied to multiple WGDs. Polyploidy generates new genomic interactions – initially resulting in “genomic and transcriptomic shock” – that must be resolved in a new polyploid lineage. This process essentially acts as a “reset” button, resulting in genomic changes that may ultimately promote adaptive speciation. This book brings together for the first time the conceptual and theoretical underpinnings of polyploid genome evolution with syntheses of the patterns and processes of genome evolution in diverse polyploid groups. Because polyploidy is most common and best studied in plants, the book emphasizes plant models, but recent studies of vertebrates and fungi are providing fresh perspectives on factors that allow polyploid speciation and shape polyploid genomes. The emerging paradigm is that polyploidy – through alterations in genome structure and gene regulation – generates genetic and phenotypic novelty that manifests itself at the chromosomal, physiological, and organismal levels, with long-term ecological and evolutionary consequences.

Download or read book Medical Enhancement and Posthumanity written by Bert Gordijn and published by Springer Science & Business Media. This book was released on 2008-10-20 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we are increasingly using new technologies to change ourselves beyond therapy and in accordance with our own desires, understanding the challenges of human enhancement has become one of the most urgent topics of the current age. This volume contributes to such an understanding by critically examining the pros and cons of our growing ability to shape human nature through technological advancements. The authors undertake careful analyses of decisive questions that will confront society as enhancement interventions using bio-, info-, neuro- and nanotechnologies become widespread in the years to come. They provide the reader with the conceptual tools necessary to address such questions fruitfully. What makes the book especially attractive is the combination of conceptual, historical and ethical approaches, rendering it highly original. In addition, the well-balanced structure allows both favourable and critical views to be voiced. Moreover, the work has a crystal clear structure. As a consequence, the book is accessible to a broad academic audience. The issues raised are of interest to a wide reflective public concerned about science and ethics, as well as to students, academics and professionals in areas such as philosophy, applied ethics, bioethics, medicine and health management.

Download or read book The Heredity of Behavior Disorders in Adults and Children written by D.L. Pauls and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current trends in morbidity suggest that by the beginning of the twen ty-first century, psychiatric illness may become the most pressing problem in public health in many of the advanced countries. As ably demonstrated by Vandenberg, Singer, and Pauls, the principal identifia ble etiology of the major psychiatric disorders is heredity; if progress is to be made in prevention and treatment of these disorders, it may have to come from improved understanding of their inheritance. A relentless increase has been observed in the frequency of mood disorders, primarily major depression but also manic-depressive ill ness, appearing earlier and more frequently in each age cohort born since (approximately) 1940. Because major depression is a recurrent disorder, whose episodes increase in frequency with age, the number of observed depressions can be expected to increase dramatically as these people reach middle and old age. The rate of suicide has also increased enormously, according to birth cohort. Starting with people born around 1935, the rate of suicide between 15 and 19 years of age has increased more than 10 times from the earliest to the most recent birth cohorts. What is not clear is if there will be a compensatory reduction in suicide rate as this cohort ages, because people likely to commit suicide will have done so earlier, or if this presages a general increase in suicide, comparable to the increase in mood disorders and perhaps a function of them.

Download or read book Handbook of Statistical Genetics written by David J. Balding and published by John Wiley & Sons. This book was released on 2008-06-10 with total page 1616 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook for Statistical Genetics is widely regarded as the reference work in the field. However, the field has developed considerably over the past three years. In particular the modeling of genetic networks has advanced considerably via the evolution of microarray analysis. As a consequence the 3rd edition of the handbook contains a much expanded section on Network Modeling, including 5 new chapters covering metabolic networks, graphical modeling and inference and simulation of pedigrees and genealogies. Other chapters new to the 3rd edition include Human Population Genetics, Genome-wide Association Studies, Family-based Association Studies, Pharmacogenetics, Epigenetics, Ethic and Insurance. As with the second Edition, the Handbook includes a glossary of terms, acronyms and abbreviations, and features extensive cross-referencing between the chapters, tying the different areas together. With heavy use of up-to-date examples, real-life case studies and references to web-based resources, this continues to be must-have reference in a vital area of research. Edited by the leading international authorities in the field. David Balding - Department of Epidemiology & Public Health, Imperial College An advisor for our Probability & Statistics series, Professor Balding is also a previous Wiley author, having written Weight-of-Evidence for Forensic DNA Profiles, as well as having edited the two previous editions of HSG.

Download or read book Bones Bodies amd Behavior written by George W. Stocking and published by Univ of Wisconsin Press. This book was released on 1990-08-28 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: History of Anthropology is a series of annual volumes, inaugurated in 1983, each broadly unified around a theme of major importance to both the history and the present practice of anthropological inquiry. Bones, Bodies, Behavior, the fifth in the series, treats a number of issues relating to the history of biological or physical anthropology: the application of the "race" idea to humankind, the comparison of animals minds to those of humans, the evolution of humans from primate forms, and the relation of science to racial ideology. Following an introductory overview of biological anthropology in Western tradition, the seven essays focus on a series of particular historical episodes from 1830 to 1980: the emergence of the race idea in restoration France, the comparative psychological thought of the American ethnologist Lewis Henry Morgan, the archeological background of the forgery of the remains "discovered" at Piltdown in 1912, their impact on paleoanthropology in the interwar period, the background and development of physical anthropology in Nazi Germany, and the attempts of Franx Boas and others to organize a consensus against racialism among British and American scientists in the late 1930s. The volume concludes with a provocative essay on physical anthropology and primate studies in the United States in the years since such a consensus was established by the UNESCO "Statements on Race" of 1950 and 1951. Bringing together the contributions of a physical anthropologist (Frank Spencer), a historical sociologist (Michael Hammond), and a number of historians of science (Elazar Barkan, Claude Blanckaert, Donna Haraway, Robert Proctor, and Marc Swetlitz), this volume will appeal to a wide range of students, scholars, and general readers interested in the place of biological assumptions in the modern anthropological tradition, in the biological bases of human behavior, in racial ideologies, and in the development of the modern human sciences.

Download or read book The Kaiser Wilhelm Institute for Anthropology Human Heredity and Eugenics 1927 1945 written by Hans-Walter Schmuhl and published by Springer Science & Business Media. This book was released on 2008-01-14 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics opened its doors in 1927, it could rely on wide political approval. In 1933 the institute and its founding director Eugen Fischer came under pressure to adjust, which they were able to ward off through Selbstgleichschaltung (auto-coordination). The Third Reich brought about a mutual beneficial servicing of science and politics. With their research into hereditary health and racial policies the institute’s employees provided the Brownshirt rulers with legitimating grounds. This volume traces the history of the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics between democracy and dictatorship. Attention is turned to the haunting transformation of the research program, the institute’s integration into the national and international science panorama, and its relationship to the ruling power. The volume also confronts the institute’s interconnection to the political crimes of Nazi Germany terminating in bestial medical crimes.

Download or read book Relict Species written by Jan Christian Habel and published by Springer Science & Business Media. This book was released on 2009-12-03 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.

Download or read book Quantitative Methods in Biological and Medical Sciences written by H.O. Lancaster and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: My original intention was to write a history of medical statistics, used in its prewar sense, expanding the writings on the subject by Major Greenwood, from which I formed many of my ideas in the early days immediately after the Second World War. In later years, I decided that the scope of his works was narrower than what I think is appropriate now, for he was writing in an era before the acceptance and use of the Fisherian methods and he was probably not aware of the mathematization of many parts of biological theory. Further, the boundary between the medical and biological sciences has largely disappeared. Many texts have now been written on branches of the theory and practice inspired by R. A. Fisher (see §4. 13). I discuss the history of the use of quantitative methods in the biological sciences, defined after the style of Peller (1967) as that branch of science that uses a quantitative approach to, or quantitative logical reasoning on, or biology. The mathematical tech any issue having to do with medicine niques are various and not classified here. Within the book I use "biological sciences" to include medicine but use the longer phrase in its title to avoid misunderstandings as to content. Moreover, most of the experimental work carried out in medical research laboratories is performed on animals other than man.

Download or read book Ecology and Evolution of Poeciliid Fishes written by Jonathan P. Evans and published by University of Chicago Press. This book was released on 2011-09-26 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of biology is populated by numerous model species or organisms. But few vertebrate groups have aided evolutionary and ecological research more than the live-bearing fishes of the family Poeciliidae. Found throughout tropical and subtropical waters, poeciliids exhibit a fascinating variety of reproductive specializations, including viviparity, matrotrophy, unisexual reproduction, and alternative mating strategies, making them ideal models for research on patterns and processes in ecology, behavior, and evolution. Ecology and Evolution of Poeciliid Fishes is a much-needed overview of the scientific potential and understanding of these live-bearing fishes. Chapters by leading researchers take up a wide range of topics, including the evolution of unisexual reproduction, life in extreme environments, life-history evolution, and genetics. Designed to provide a single and highly approachable reference, Ecology and Evolution of Poeciliid Fishes will appeal to students and specialists interested in all aspects of evolutionary ecology.
