This book was released on 2005-09-28 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: In December 2004, the National Academy of Sciences sponsored a colloquium on "Systematics and the Origin of Species" to celebrate Ernst Mayr's 100th anniversary and to explore current knowledge concerning the origin of species. In 1942, Ernst Mayr, one of the twentieth century's greatest scientists, published Systematics and the Origin of Species, a seminal book of the modern theory of evolution, where he advanced the significance of population variation in the understanding of evolutionary process and the origin of new species. Mayr formulated the transition from Linnaeus's static species concept to the dynamic species concept of the modern theory of evolution and emphasized the species as a community of populations, the role of reproductive isolation, and the ecological interactions between species. In addition to a preceding essay by Edward O. Wilson, this book includes the 16 papers presented by distinguished evolutionists at the colloquium. The papers are organized into sections covering the origins of species barriers, the processes of species divergence, the nature of species, the meaning of "species," and genomic approaches for understanding diversity and speciation.
Download or read book Tempo and Mode in Evolution written by for the National Academy of Sciences and published by National Academies Press. This book was released on 1995-02-09 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since George Gaylord Simpson published Tempo and Mode in Evolution in 1944, discoveries in paleontology and genetics have abounded. This volume brings together the findings and insights of today's leading experts in the study of evolution, including Ayala, W. Ford Doolittle, and Stephen Jay Gould. The volume examines early cellular evolution, explores changes in the tempo of evolution between the Precambrian and Phanerozoic periods, and reconstructs the Cambrian evolutionary burst. Long-neglected despite Darwin's interest in it, species extinction is discussed in detail. Although the absence of data kept Simpson from exploring human evolution in his book, the current volume covers morphological and genetic changes in human populations, contradicting the popular claim that all modern humans descend from a single woman. This book discusses the role of molecular clocks, the results of evolution in 12 populations of Escherichia coli propagated for 10,000 generations, a physical map of Drosophila chromosomes, and evidence for "hitchhiking" by mutations.
Download or read book The Theoretical Individual written by Michael Charles Tobias and published by Springer. This book was released on 2018-01-03 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can the one influence the many? From posing seminal questions about what comprises a human individual, to asking whether human evolution is alive and well, favoring individuals or the species, this work is a daring, up-to-the-minute overview of an urgent, multidisciplinary premise. It explores the extent to which human history provides empirical evidence for the capacity of an individual to exert meaningful suasion over their species, and asks: Can an individual influence the survival of the human species and the planet? If there are to be cultures of transformation dedicated to seeing us all through the Sixth Extinction Spasm, the Anthropocene, inflicting as little biological havoc as possible, what might such orientations—a collective, widespread biophilia, or reverence for nature—look like? In this powerful work, with a combination of data and direct observation, the authors invite readers to explore how such transformations might resonate throughout the human community; in what ways a person might overcome the seemingly insurmountable environmental tumult our species has unleashed; the clear and salient motives, ethics, aspirations and pragmatic idealism he/she might mirror and embrace in order to effect a profound difference—at the individual level—for all of life and life’s myriad habitats. Chapters illuminate an ambitiously broad digest of research from two-dozen disciplines. Those include ecodynamics, biosemiotics, neural plasticity, anthropology, paleontology and the history of science, among others. All converge upon a set of ethics-based scenarios for mitigating ecological damage to ourselves and other life forms. This highly readable and tightly woven treatise speaks to scientists, students and all those who are concerned about ethical activism and the future of the biosphere. Michael Charles Tobias and Jane Gray Morrison are ecological philosophers and animal liberation activists who have worked for decades to help enrich our understanding of ecosystem dynamics and humanity’s ambiguous presence amid that great orchestra that is nature.

Download or read book The Unified Neutral Theory of Biodiversity and Biogeography written by Stephen P. Hubbell and published by Princeton University Press. This book was released on 2011-06-27 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context. Until now biogeography (the study of the geographic distribution of species) and biodiversity (the study of species richness and relative species abundance) have had largely disjunct intellectual histories. In this book, Stephen Hubbell develops a formal mathematical theory that unifies these two fields. When a speciation process is incorporated into Robert H. MacArthur and Edward O. Wilson's now classical theory of island biogeography, the generalized theory predicts the existence of a universal, dimensionless biodiversity number. In the theory, this fundamental biodiversity number, together with the migration or dispersal rate, completely determines the steady-state distribution of species richness and relative species abundance on local to large geographic spatial scales and short-term to evolutionary time scales. Although neutral, Hubbell's theory is nevertheless able to generate many nonobvious, testable, and remarkably accurate quantitative predictions about biodiversity and biogeography. In many ways Hubbell's theory is the ecological analog to the neutral theory of genetic drift in genetics. The unified neutral theory of biogeography and biodiversity should stimulate research in new theoretical and empirical directions by ecologists, evolutionary biologists, and biogeographers.
Download or read book Variation and Evolution in Plants and Microorganisms written by National Academy of Sciences and published by National Academies Press. This book was released on 2000-10-11 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The present book is intended as a progress report on [the] synthetic approach to evolution as it applies to the plant kingdom." With this simple statement, G. Ledyard Stebbins formulated the objectives of Variation and Evolution in Plants, published in 1950, setting forth for plants what became known as the "synthetic theory of evolution" or "the modern synthesis." The pervading conceit of the book was the molding of Darwin's evolution by natural selection within the framework of rapidly advancing genetic knowledge. At the time, Variation and Evolution in Plants significantly extended the scope of the science of plants. Plants, with their unique genetic, physiological, and evolutionary features, had all but been left completely out of the synthesis until that point. Fifty years later, the National Academy of Sciences convened a colloquium to update the advances made by Stebbins. This collection of 17 papers marks the 50th anniversary of the publication of Stebbins' classic. Organized into five sections, the book covers: early evolution and the origin of cells, virus and bacterial models, protoctist models, population variation, and trends and patterns in plant evolution.

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
Download or read book The Altenberg 16 written by Suzan Mazur and published by North Atlantic Books. This book was released on 2010 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new theory of evolution begins to emerge in the pages of The Altenberg 16: An Expos of the Evolution Industry. Written by Suzan Mazur--a print and television journalist whose reports have appeared in the Financial Times, The Economist, Archaeology, Omni, and many other publications--the book is a front row seat to the thinking of the great evolutionary science minds of our time about the need to reformulate the neo-Darwinian theory of evolution. We hear from world renowned scientists such as Richard Lewontin, Lynn Margulis, Niles Eldredge, Richard Dawkins, the "evo-devo" revolutionaries, NASA astrobiologists, and others. The book grew out of a story Mazur broke online in March 2008--titled "Altenberg The Woodstock of Evolution?"--about the now famous meeting at Konrad Lorenz Institute in Altenberg, Austria in July 2008, where 16 scientists discussed expanding evolutionary thinking beyond outdated hypotheses. (MIT will publish the proceedings in April 2010.) Science magazine noted that Mazur's reporting "reverberated throughout the evolutionary biology community." Mazur says she was punished for getting out in front of the story and banned from the symposium but realized the story was bigger than Altenberg (which covered events beginning 500 million years ago) and spoke to scientists who were not invited, including those investigating pre-biotic evolution. She came to the conclusion that evolutionary science suffers because many in the scientific establishment refuse to acknowledge that the old science has served its purpose and there is disagreement about what the new evolution paradigm is. She thinks the dam is now breaking because the public (who funds science) has become a party to the discourse via the Internet and seeks answers to fundamental questions about evolution that scientists so far can't definitively answer.
Download or read book Improbable Destinies written by Jonathan B. Losos and published by Penguin. This book was released on 2017-08-08 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major new book overturning our assumptions about how evolution works Earth’s natural history is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. But evolutionary biologists also point out many examples of contingency, cases where the tiniest change—a random mutation or an ancient butterfly sneeze—caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary flukes? And what does that say about life on other planets? Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be. Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.
Download or read book Suffering Made Real written by M. Susan Lindee and published by University of Chicago Press. This book was released on 2008-10-10 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atomic bombs dropped on Hiroshima and Nagasaki in August of 1945 unleashed a force as mysterious as it was deadly—radioactivity. In 1946, the United States government created the Atomic Bomb Casualty Commission (ABCC) to serve as a permanent agency in Japan with the official mission of studying the medical effects of radiation on the survivors. The next ten years saw the ABCC's most intensive research on the genetic effects of radiation, and up until 1974 the ABCC scientists published papers on the effects of radiation on aging, life span, fertility, and disease. Suffering Made Real is the first comprehensive history of the ABCC's research on how radiation affected the survivors of the atomic bomb. Arguing that Cold War politics and cultural values fundamentally shaped the work of the ABCC, M. Susan Lindee tells the compelling story of a project that raised disturbing questions about the ethical implications of using human subjects in scientific research. How did the politics of the emerging Cold War affect the scientists' biomedical research and findings? How did the ABCC document and publicly present the effects of radiation? Why did the ABCC refuse to provide medical treatment to the survivors? Through a detailed examination of ABCC policies, archival materials, the minutes of committee meetings, newspaper accounts, and interviews with ABCC scientists, Lindee explores how political and cultural interests were reflected in the day-to-day operations of this controversial research program. Set against a period of conflicting views of nuclear weapons and nuclear power, Suffering Made Real follows the course of a politically charged research program and reveals in detail how politics and cultural values can shape the conduct, results, and uses of science.
Download or read book Gene Drives on the Horizon written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
