| define locus in biology: Biology's First Law Daniel W. McShea, Robert N. Brandon, 2010-07-15 Life on earth is characterized by three striking phenomena that demand explanation: adaptation—the marvelous fit between organism and environment; diversity—the great variety of organisms; and complexity—the enormous intricacy of their internal structure. Natural selection explains adaptation. But what explains diversity and complexity? Daniel W. McShea and Robert N. Brandon argue that there exists in evolution a spontaneous tendency toward increased diversity and complexity, one that acts whether natural selection is present or not. They call this tendency a biological law—the Zero-Force Evolutionary Law, or ZFEL. This law unifies the principles and data of biology under a single framework and invites a reconceptualization of the field of the same sort that Newton’s First Law brought to physics. Biology’s First Law shows how the ZFEL can be applied to the study of diversity and complexity and examines its wider implications for biology. Intended for evolutionary biologists, paleontologists, and other scientists studying complex systems, and written in a concise and engaging format that speaks to students and interdisciplinary practitioners alike, this book will also find an appreciative audience in the philosophy of science. |
| define locus in biology: Crumbling Genome Alexey S. Kondrashov, 2017-07-12 A thought-provoking exploration of deleterious mutations in the human genome and their effects on human health and wellbeing Despite all of the elaborate mechanisms that a cell employs to handle its DNA with the utmost care, a newborn human carries about 100 new mutations, originated in their parents, about 10 of which are deleterious. A mutation replacing just one of the more than three billion nucleotides in the human genome may lead to synthesis of a dysfunctional protein, and this can be inconsistent with life or cause a tragic disease. Several percent of even young people suffer from diseases that are caused, exclusively or primarily, by pre ]existing and new mutations in their genomes, including both a wide variety of genetically simple Mendelian diseases and diverse complex diseases such as birth anomalies, diabetes, and schizophrenia. Milder, but still substantial, negative effects of mutations are even more pervasive. As of now, we possess no means of reducing the rate at which mutations appear spontaneously. However, the recent flood of genomic data made possible by next-generation methods of DNA sequencing, enabled scientists to explore the impacts of deleterious mutations on humans with previously unattainable precision and begin to develop approaches to managing them. Written by a leading researcher in the field of evolutionary genetics, Crumbling Genome reviews the current state of knowledge about deleterious mutations and their effects on humans for those in the biological sciences and medicine, as well as for readers with only a general scientific literacy and an interest in human genetics. Provides an extensive introduction to the fundamentals of evolutionary genetics with an emphasis on mutation and selection Discusses the effects of pre-existing and new mutations on human genotypes and phenotypes Provides a comprehensive review of the current state of knowledge in the field and considers crucial unsolved problems Explores key ethical, scientific, and social issues likely to become relevant in the near future as the modification of human germline genotypes becomes technically feasible Crumbling Genome is must-reading for students and professionals in human genetics, genomics, bioinformatics, evolutionary biology, and biological anthropology. It is certain to have great appeal among all those with an interest in the links between genetics and evolution and how they are likely to influence the future of human health, medicine, and society. |

| define locus in biology: The Regulatory Genome Eric H. Davidson, 2010-07-19 Gene regulatory networks are the most complex, extensive control systems found in nature. The interaction between biology and evolution has been the subject of great interest in recent years. The author, Eric Davidson, has been instrumental in elucidating this relationship. He is a world renowned scientist and a major contributor to the field of developmental biology. The Regulatory Genome beautifully explains the control of animal development in terms of structure/function relations of inherited regulatory DNA sequence, and the emergent properties of the gene regulatory networks composed of these sequences. New insights into the mechanisms of body plan evolution are derived from considerations of the consequences of change in developmental gene regulatory networks. Examples of crucial evidence underscore each major concept. The clear writing style explains regulatory causality without requiring a sophisticated background in descriptive developmental biology. This unique text supersedes anything currently available in the market. - The only book in the market that is solely devoted to the genomic regulatory code for animal development - Written at a conceptual level, including many novel synthetic concepts that ultimately simplify understanding - Presents a comprehensive treatment of molecular control elements that determine the function of genes - Provides a comparative treatment of development, based on principles rather than description of developmental processes - Considers the evolutionary processes in terms of the structural properties of gene regulatory networks - Includes 42 full-color descriptive figures and diagrams |
| define locus in biology: Biometrical genetics Kenneth Mather, John L. Jinks, 2013-11-11 The properties of continuous variation are basic to the theory of evolution and to the practice of plant and animal improvement. Yet the genetical study of continuous variation has lagged far behind that of discontinuous variation. The reason for this situation is basically methodological. Mendel gave us not merely his principles of heredity, but also a method of experiment by which these principles could be tested over a wider range of living species, and extended into the elaborate genetical theory of today. The power of this tool is well attested by the speed with which genetics has grown. In less than fifty years, it has not only developed a theoretical structure which is unique in the biological sciences, but has established a union with nuclear cytology so close that the two have become virtually a single science offering us a new approach to problems so diverse as those of evolution, development, disease, cellular chemistry and human welfare. Much of this progress would have been impossible and all would have been slower without the Mendelian method of recognizing and using unit differences in the genetic materials. |
| define locus in biology: Toward Precision Medicine National Research Council, Division on Earth and Life Studies, Board on Life Sciences, Committee on A Framework for Developing a New Taxonomy of Disease, 2012-01-16 Motivated by the explosion of molecular data on humans-particularly data associated with individual patients-and the sense that there are large, as-yet-untapped opportunities to use this data to improve health outcomes, Toward Precision Medicine explores the feasibility and need for a new taxonomy of human disease based on molecular biology and develops a potential framework for creating one. The book says that a new data network that integrates emerging research on the molecular makeup of diseases with clinical data on individual patients could drive the development of a more accurate classification of diseases and ultimately enhance diagnosis and treatment. The new taxonomy that emerges would define diseases by their underlying molecular causes and other factors in addition to their traditional physical signs and symptoms. The book adds that the new data network could also improve biomedical research by enabling scientists to access patients' information during treatment while still protecting their rights. This would allow the marriage of molecular research and clinical data at the point of care, as opposed to research information continuing to reside primarily in academia. Toward Precision Medicine notes that moving toward individualized medicine requires that researchers and health care providers have access to very large sets of health- and disease-related data linked to individual patients. These data are also critical for developing the information commons, the knowledge network of disease, and ultimately the new taxonomy. |

| define locus in biology: Evolution of Translational Omics Institute of Medicine, Board on Health Sciences Policy, Board on Health Care Services, Committee on the Review of Omics-Based Tests for Predicting Patient Outcomes in Clinical Trials, 2012-09-13 Technologies collectively called omics enable simultaneous measurement of an enormous number of biomolecules; for example, genomics investigates thousands of DNA sequences, and proteomics examines large numbers of proteins. Scientists are using these technologies to develop innovative tests to detect disease and to predict a patient's likelihood of responding to specific drugs. Following a recent case involving premature use of omics-based tests in cancer clinical trials at Duke University, the NCI requested that the IOM establish a committee to recommend ways to strengthen omics-based test development and evaluation. This report identifies best practices to enhance development, evaluation, and translation of omics-based tests while simultaneously reinforcing steps to ensure that these tests are appropriately assessed for scientific validity before they are used to guide patient treatment in clinical trials. |
| define locus in biology: Evolution by Gene Duplication Susumu Ohno, 2013-12-11 It is said that necessity is the mother of invention. To be sure, wheels and pulleys were invented out of necessity by the tenacious minds of upright citi zens. Looking at the history of mankind, however, one has to add that Ieisure is the mother of cultural improvement. Man's creative genius flourished only when his mind, freed from the worry of daily toils, was permitted to entertain apparently useless thoughts. In the same manner, one might say with regard to evolution that natural selection mere(y tnodifted, while redundanry created. Natural selection has been extremely effective in policing alleHe mutations which arise in already existing gene loci. Because of natural selection, organisms have been able to adapt to changing environments, and by adaptive radiation many new species were created from a common ancestral form. Y et, being an effective policeman, natural selection is extremely conservative by nature. Had evolution been entirely dependent upon natural selection, from a bacterium only numerous forms of bacteria would have emerged. The creation of metazoans, vertebrates and finally mammals from unicellular organisms would have been quite impos sible, for such big leaps in evolution required the creation of new gene loci with previously nonexistent functions. Only the cistron which became redun dant was able to escape from the relentless pressure of natural selection, and by escaping, it accumulated formerly forbidden mutations to emerge as a new gene locus. |

| define locus in biology: Systematics and the Origin of Species National Academy of Sciences, 2005-09-28 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. |

| define locus in biology: Locus of Authority William G. Bowen, Eugene M. Tobin, 2017-05-30 Locus of Authority argues that every issue facing today's colleges and universities, from stagnant degree completion rates to worrisome cost increases, is exacerbated by a century-old system of governance that desperately requires change. While prior studies have focused on boards of trustees and presidents, few have looked at the place of faculty within the governance system. Specifically addressing faculty roles in this structure, William G. Bowen and Eugene M. Tobin ask: do higher education institutions have what it takes to reform effectively from within? Bowen and Tobin use case studies of four very different institutions--the University of California, Princeton University, Macalester College, and the City University of New York--to demonstrate that college and university governance has capably adjusted to the necessities of the moment and that governance norms and policies should be assessed in the context of historical events. The authors examine how faculty roles have evolved since colonial days to drive change but also to stand in the way of it. Bowen and Tobin make the case that successful reform depends on the artful consideration of technological, financial, and cultural developments, such as the explosion in online learning. Stressing that they do not want to diminish faculty roles but to facilitate their most useful contributions, Bowen and Tobin explore whether departments remain the best ways through which to organize decision making and if the concepts of academic freedom and shared governance need to be sharpened and redefined. Locus of Authority shows that the consequences of not addressing college and university governance are more than the nation can afford-- |

| define locus in biology: The Evaluation of Forensic DNA Evidence National Research Council, Division on Earth and Life Studies, Commission on Life Sciences, Committee on DNA Forensic Science: An Update, 1996-12-12 In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book. |

| define locus in biology: Measures of Personality and Social Psychological Constructs Gregory J. Boyle, Donald H. Saklofske, Gerald Matthews, 2014-09-04 Measures of Personality and Social Psychological Constructs assists researchers and practitioners by identifying and reviewing the best scales/measures for a variety of constructs. Each chapter discusses test validity, reliability, and utility. Authors have focused on the most often used and cited scales/measures, with a particular emphasis on those published in recent years. Each scale is identified and described, the sample on which it was developed is summarized, and reliability and validity data are presented, followed by presentation of the scale, in full or in part, where such permission has been obtained. Measures fall into five broad groups. The emotional disposition section reviews measures of general affective tendencies, and/or cognitive dispositions closely linked to emotion. These measures include hope and optimism, anger and hostility, life satisfaction, self-esteem, confidence, and affect dimensions. Emotion regulation scales go beyond general dispositions to measure factors that may contribute to understanding and managing emotions. These measures include alexithymia, empathy, resiliency, coping, sensation seeking, and ability and trait emotional intelligence. The interpersonal styles section introduces some traditional social–psychological themes in the context of personality assessment. These measures include adult attachment, concerns with public image and social evaluation, and forgiveness. The vices and virtues section reflects adherence to moral standards as an individual characteristic shaped by sociocultural influences and personality. These measures include values and moral personality, religiosity, dark personalities (Machiavellianism,narcissism, and subclinical psychopathy), and perfectionism. The sociocultural interaction and conflict section addresses relationships between different groups and associated attitudes. These measures include cross-cultural values, personality and beliefs, intergroup contact, stereotyping and prejudice, attitudes towards sexual orientation, and personality across cultures. - Encompasses 25 different areas of psychology research - Each scale has validity, reliability info, info on test bias, etc - Multiple scales discussed for each construct - Discussion of which scales are appropriate in which circumstances and to what populations - Examples of scales included |
