Variation


Book Description

Darwin's theory of evolution by natural selection was based on the observation that there is variation between individuals within the same species. This fundamental observation is a central concept in evolutionary biology. However, variation is only rarely treated directly. It has remained peripheral to the study of mechanisms of evolutionary change. The explosion of knowledge in genetics, developmental biology, and the ongoing synthesis of evolutionary and developmental biology has made it possible for us to study the factors that limit, enhance, or structure variation at the level of an animals' physical appearance and behavior. Knowledge of the significance of variability is crucial to this emerging synthesis. Variation situates the role of variability within this broad framework, bringing variation back to the center of the evolutionary stage. Provides an overview of current thinking on variation in evolutionary biology, functional morphology, and evolutionary developmental biology Written by a team of leading scholars specializing on the study of variation Reviews of statistical analysis of variation by leading authorities Key chapters focus on the role of the study of phenotypic variation for evolutionary, developmental, and post-genomic biology




Types of Variation


Book Description

This volume interfaces three fields of linguistics rarely discussed in the same context. Its underlying theme is linguistic variation, and the ways in which historical linguists and dialectologists may learn from insights offered by typology, and vice versa. The aim of the contributions is to raise the awareness of these linguistic subdisciplines of each other and to encourage their cross-fertilization to their mutual benefit. If linguistic typology is to unify the study of all types of linguistic variation, this variation, both diatopic and diachronic, will enrich typological research itself. With the aim of capturing the relevant dimensions of variation, the studies in this volume make use of new methodologies, including electronic corpora and databases, which enable cross- and intralinguistic comparisons dialectally and across time. Based on original research and unified by an innovative theme, the volume will be of interest to both students and teachers of linguistics and Germanic languages.




Evaluating Human Genetic Diversity


Book Description

This book assesses the scientific value and merit of research on human genetic differencesâ€"including a collection of DNA samples that represents the whole of human genetic diversityâ€"and the ethical, organizational, and policy issues surrounding such research. Evaluating Human Genetic Diversity discusses the potential uses of such collection, such as providing insight into human evolution and origins and serving as a springboard for important medical research. It also addresses issues of confidentiality and individual privacy for participants in genetic diversity research studies.




Applications of Toxicogenomic Technologies to Predictive Toxicology and Risk Assessment


Book Description

The new field of toxicogenomics presents a potentially powerful set of tools to better understand the health effects of exposures to toxicants in the environment. At the request of the National Institute of Environmental Health Sciences, the National Research Council assembled a committee to identify the benefits of toxicogenomics, the challenges to achieving them, and potential approaches to overcoming such challenges. The report concludes that realizing the potential of toxicogenomics to improve public health decisions will require a concerted effort to generate data, make use of existing data, and study data in new waysâ€"an effort requiring funding, interagency coordination, and data management strategies.
