Book Synopsis Evolution Through Genetic Exchange by : Michael L Arnold
Download or read book Evolution Through Genetic Exchange written by Michael L Arnold and published by Oxford University Press. This book was released on 2006-07-27 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: More and more data indicate that evolution has resulted in lineages consisting of mosaics of genes derived from different ancestors. It is therefore becoming increasingly clear that the tree is an inadequate metaphor of evolutionary change. In this book, Arnold promotes the 'web-of-life' metaphor as a more appropriate representation of evolutionary change in all lifeforms.
Book Synopsis Divergence with Genetic Exchange by : Michael Lynn Arnold
Download or read book Divergence with Genetic Exchange written by Michael Lynn Arnold and published by Oxford University Press. This book was released on 2016 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the processes associated with evolutionary divergence and diversification. The focus, as the title indicates, is on the role played by the exchange of genes between divergent lineages. The study of genetic exchange resulting from natural hybridization, horizontal gene transfer, and viral recombination has long been marked by controversy between researchers holding different conceptual frameworks. Those subscribing to a doctrine of "species purity" have traditionally been reluctant to recognize inferences suggesting anything other than a marginal role for non-allopatric divergence leading to gene transfer between different lineages. However, an increasing number of evolutionary biologists now accept that there is a growing body of evidence indicating the existence of non-allopatric diversification across many lineages and all domains of biological diversity.

Book Synopsis Lateral Gene Transfer in Evolution by : Uri Gophna
Download or read book Lateral Gene Transfer in Evolution written by Uri Gophna and published by Springer Science & Business Media. This book was released on 2013-07-20 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the phenomenon of lateral gene transfer has been known since the 1940's, it was the genomics era that has really revealed the extent and many facets of this evolutionary/genetic phenomenon. Even in the early 2000s with but a handful of genomes available it became clear that the nature of microorganisms is full of genetic exchange between lineages that are sometimes far apart. The years following this saw an explosion of genomic data, which shook the "tree of life" and also raised doubts about the most appropriate species concepts for prokaryotes. This book attempts to represent the many-fold contributions of LGT to the evolution of micro and, to an extent, macro-organisms by focusing on the areas where the Editor felt it had the largest impact: metabolic innovations and adaptations and speciation.

Book Synopsis Genetics and Evolution of Infectious Diseases by : Michel Tibayrenc
Download or read book Genetics and Evolution of Infectious Diseases written by Michel Tibayrenc and published by Elsevier. This book was released on 2010-12-17 with total page 773 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetics and Evolution of Infectious Diseases is at the crossroads between two major scientific fields of the 21st century: evolutionary biology and infectious diseases. The genomic revolution has upset modern biology and has revolutionized our approach to ancient disciplines such as evolutionary studies. In particular, this revolution is profoundly changing our view on genetically driven human phenotypic diversity, and this is especially true in disease genetic susceptibility. Infectious diseases are indisputably the major challenge of medicine. When looking globally, they are the number one killer of humans and therefore the main selective pressure exerted on our species. Even in industrial countries, infectious diseases are now far less under control than 20 years ago. The first part of this book covers the main features and applications of modern technologies in the study of infectious diseases. The second part provides detailed information on a number of the key infectious diseases such as malaria, SARS, avian flu, HIV, tuberculosis, nosocomial infections and a few other pathogens that will be taken as examples to illustrate the power of modern technologies and the value of evolutionary approaches. Takes an integrated approach to infectious diseases Includes contributions from leading authorities Provides the latest developments in the field
Book Synopsis Sequence — Evolution — Function by : Eugene V. Koonin
Download or read book Sequence — Evolution — Function written by Eugene V. Koonin and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequence - Evolution - Function is an introduction to the computational approaches that play a critical role in the emerging new branch of biology known as functional genomics. The book provides the reader with an understanding of the principles and approaches of functional genomics and of the potential and limitations of computational and experimental approaches to genome analysis. Sequence - Evolution - Function should help bridge the "digital divide" between biologists and computer scientists, allowing biologists to better grasp the peculiarities of the emerging field of Genome Biology and to learn how to benefit from the enormous amount of sequence data available in the public databases. The book is non-technical with respect to the computer methods for genome analysis and discusses these methods from the user's viewpoint, without addressing mathematical and algorithmic details. Prior practical familiarity with the basic methods for sequence analysis is a major advantage, but a reader without such experience will be able to use the book as an introduction to these methods. This book is perfect for introductory level courses in computational methods for comparative and functional genomics.
Book Synopsis Oversight and Review of Clinical Gene Transfer Protocols by : Institute of Medicine
Download or read book Oversight and Review of Clinical Gene Transfer Protocols written by Institute of Medicine and published by National Academies Press. This book was released on 2014-03-27 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene transfer research is a rapidly advancing field that involves the introduction of a genetic sequence into a human subject for research or diagnostic purposes. Clinical gene transfer trials are subject to regulation by the U.S. Food and Drug Administration (FDA) at the federal level and to oversight by institutional review boards (IRBs) and institutional biosafety committees (IBCs) at the local level before human subjects can be enrolled. In addition, at present all researchers and institutions funded by the National Institutes of Health (NIH) are required by NIH guidelines to submit human gene transfer protocols for advisory review by the NIH Recombinant DNA Advisory Committee (RAC). Some protocols are then selected for individual review and public discussion. Oversight and Review of Clinical Gene Transfer Protocols provides an assessment of the state of existing gene transfer science and the current regulatory and policy context under which research is investigated. This report assesses whether the current oversight of individual gene transfer protocols by the RAC continues to be necessary and offers recommendations concerning the criteria the NIH should employ to determine whether individual protocols should receive public review. The focus of this report is on the standards the RAC and NIH should use in exercising its oversight function. Oversight and Review of Clinical Gene Transfer Protocols will assist not only the RAC, but also research institutions and the general public with respect to utilizing and improving existing oversight processes.

Book Synopsis Horizontal Gene Transfer by : Maria Boekels Gogarten
Download or read book Horizontal Gene Transfer written by Maria Boekels Gogarten and published by Humana Press. This book was released on 2010-11-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horizontal gene transfer (HGT) events encompass processes as varied as the exchange of genetic material between microbes coexisting in the same environment, between symbiotic bacteria and their eukaryotic hosts, and the evolution of organelles by symbiosis, in which whole genomes are acquired. In Horizontal Gene Transfer: Genomes in Flux, expert researchers contribute an overview of HGT concepts as well as specific case histories that highlight the most current progress to inspire future work. Divided into three sections, the volume begins with an overview of terminology, concepts and the implications of HGT on current evolutionary thought and philosophy, and continues with methods involving computer and bioinformatics analyses of genomic data as well as molecular biology techniques for identifying, quantifying, and differentiating instances of HGT. A section of case studies follows, which provides detailed accounts of how HGT has shaped evolution across the diversity of organisms and organismal lineages. As a volume of the highly successful Methods in Molecular BiologyTM series, this work provides the kind of detailed description and implementation advice that is crucial for getting optimal results. Cutting-edge and thoroughly detailed, Horizontal Gene Transfer: Genomes in Flux examines how HGT has contributed to genome evolution and how understanding HGT impacts our ability to accurately reconstruct and comprehend the web-like evolutionary history in order to aid scientists in furthering their own research.

Book Synopsis Horizontal Gene Transfer by : Tomás G. Villa
Download or read book Horizontal Gene Transfer written by Tomás G. Villa and published by Springer. This book was released on 2019-08-13 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on the evolutionary impact of horizontal gene transfer processes on pathogenicity, environmental adaptation and biological speciation. Newly acquired genetic material has been considered as a driving force in evolution for prokaryotic genomes for many years, with recent technical developments advancing this field further. However, the extent and implications of gene transfer between prokaryotes and eukaryotes still raise controversies. This multi-authored volume introduces various means by which DNA can be exchanged, covers gene transfer between prokaryotes and their viruses as well as between bacteria and eukaryotes, such as fungi, plants and animals, and addresses the role of horizontal gene transfer in human diseases. Aspects discussed also include the relevance for virulence and drug resistance development on one hand, and for the occurrence of naturally derived antibiotics and other secondary metabolites on the other hand. This book offers new insights to anyone interested in genome evolution and the exchange of DNA between the different domains of life, the genetic toolkit for adaptation and the emergence of multidrug resistant bacteria.
Book Synopsis Genes, Categories, and Species by : Jody Hey
Download or read book Genes, Categories, and Species written by Jody Hey and published by Oxford University Press on Demand. This book was released on 2001 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Genes, Categories and Species, Jody Hey provides an enlightening new solution to one of biology's most ironic and perplexing puzzles. When Darwin showed that life evolves, and that it does so by natural selection, he transformed our understanding of living things. But the very question Darwin addressed-the nature of species-continues to pose an awkward conundrum for biologists. Despite enormous efforts by a great many scholars, biologists still cannot agree on how to identify species or even how to define the word "species." Genes, Categories, and Species is not like other books on the species problem, for it does not begin by asking, "What is a species?" Instead, it focuses on the very fact that biologists are stumped by species and their curious behavior in coping with that uncertainty. Faced with a persistent conundrum-and no lack of data on the subject-biologists who ponder the species problem have ceased to ask the most essential of scientific questions: "What new information do we need to resolve the problem?" This is the question that motivates this book and leads to the discoveries it reveals. The answer to the species problem lies not with the processes and patterns of biological diversity, Hey contends, but rather in the way the human mind perceives and categorizes that diversity. The promise of this book is twofold. First, it allows biologists to understand the causes of the species problem and to use this knowledge to avoid the major confusions that arise over species. Second, with its explanation of the species problem, it gives scholars and students of human nature a humbling example of how ill-suited the human mind is for certain kinds of scientific questions.
Book Synopsis Reticulate Evolution by : Nathalie Gontier
Download or read book Reticulate Evolution written by Nathalie Gontier and published by Springer. This book was released on 2015-07-09 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written for non-experts, this volume introduces the mechanisms that underlie reticulate evolution. Chapters are either accompanied with glossaries that explain new terminology or timelines that position pioneering scholars and their major discoveries in their historical contexts. The contributing authors outline the history and original context of discovery of symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow and infectious heredity. By applying key insights from the areas of molecular (phylo)genetics, microbiology, virology, ecology, systematics, immunology, epidemiology and computational science, they demonstrate how reticulate evolution impacts successful survival, fitness and speciation. Reticulate evolution brings forth a challenge to the standard Neo-Darwinian framework, which defines life as the outcome of bifurcation and ramification patterns brought forth by the vertical mechanism of natural selection. Reticulate evolution puts forward a pattern in the tree of life that is characterized by horizontal mergings and lineage crossings induced by symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow and infective heredity, making the “tree of life” look more like a “web of life.” On an epistemological level, the various means by which hereditary material can be transferred horizontally challenges our classic notions of units and levels of evolution, fitness, modes of transmission, linearity, communities and biological individuality. The case studies presented examine topics including the origin of the eukaryotic cell and its organelles through symbiogenesis; the origin of algae through primary and secondary symbiosis and dinoflagellates through tertiary symbiosis; the superorganism and holobiont as units of evolution; how endosymbiosis induces speciation in multicellular life forms; transferrable and non-transferrable plasmids and how they symbiotically interact with their host; the means by which pro- and eukaryotic organisms transfer genes laterally (bacterial transformation, transduction and conjugation as well as transposons and other mobile genetic elements); hybridization and divergence with gene flow in sexually-reproducing individuals; current (human) microbiome and viriome studies that impact our knowledge concerning the evolution of organismal health and acquired immunity; and how symbiosis and symbiogenesis can be modelled in computational evolution.
