Relentless Evolution

At a glance, most species seem adapted to the environment in which they live. Yet species relentlessly evolve, and populations within species evolve in different ways. Evolution, as it turns out, is much more dynamic than biologists realized just a few decades ago. In Relentless Evolution, John N. Thompson explores why adaptive evolution never ceases and why natural selection acts on species in so many different ways. Thompson presents a view of life in which ongoing evolution is essential and inevitable. Each chapter focuses on one of the major problems in adaptive evolution: How fast is evolution? How strong is natural selection? How do species co-opt the genomes of other species as they adapt? Why does adaptive evolution sometimes lead to more, rather than less, genetic variation within populations? How does the process of adaptation drive the evolution of new species? How does coevolution among species continually reshape the web of life? And, more generally, how are our views of adaptive evolution changing? Relentless Evolution draws on studies of all the major forms of life—from microbes that evolve in microcosms within a few weeks to plants and animals that sometimes evolve in detectable ways within a few decades. It shows evolution not as a slow and stately process, but rather as a continual and sometimes frenetic process that favors yet more evolutionary change.

Casebooks in business history are designed to instruct students in classrooms and boardrooms about the evolution of business management. The first casebook for the study of business history in a Canadian context, Joseph E. Martin's text will help students, both in the classroom and the boardroom, understand the Canadian economy and guide them in making sound decisions and contributing to a healthy, growing economy. Thirteen original case studies from the mid-nineteenth to the twenty-first centuries deal with different industry sectors as well as individual corporations and managers. Overviews provide context by examining major public policy decisions and key developments in the financial system that have affected business practices. Martin also presents eight original tables that trace the evolution of the 60 largest Canadian corporations between 1905 and 2005. Relentless Change is an invaluable resource for instructors and business students and clearly demonstrates how businesses are affected by the interaction of individual decisions, policy changes, and market trends.

Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

The speedy development of information communication technology, electronic libraries, digital libraries, availability of e-resources and collective demand of library users has changed the scenario of libraries and library professionals. Today all the users find the instant and desktop based library and information services. But only few institute libraries provide that type of services to their end user. This study highlights that out of 56 central universities in India only few universities are concentrate on web-based library resources and services to their end users. This paper also discusses the information availability in the websites like library URL, OPAC, e-resources, open access resources etc.

In this ground-breaking book, Aristotelian and evolutionary understandings of human social nature are brought together to provide an integrative, psychological account of human ethics. The book emphasizes the profound ways that human identity and action are immersed in an ongoing social world.

Evolutionary quantitative genetics (EQG) provides a formal theoretical foundation for quantitatively linking natural selection and genetic variation to the rate and expanse of adaptive evolution. It has become the dominant conceptual framework for interpreting the evolution of quantitative traits in terms of elementary forces (mutation, inheritance, selection, and drift). Despite this success, the relevance of EQG to many biological scenarios remains relatively unappreciated, with numerous fields yet to fully embrace its approach. Part of the reason for this lag is that conceptual advances in EQG have not yet been fully synthesized and made accessible to a wider academic audience. A comprehensive, accessible overview is therefore now timely, and Evolutionary Quantitative Genetics provides this much-needed synthesis. The central argument of the book is that an adaptive landscape concept can be used to understand both evolutionary process within lineages and the pattern of adaptive radiations. In particular, it provides a convincing argument that models with a moving adaptive peak carry us further than any other conceptual approach yet devised. Although additive theory holds center stage, the book mentions and references departures from additivity including non-Gaussian distributions of allelic effects, dominance, epistasis, maternal effects and phenotypic plasticity. This accessible, advanced textbook is aimed principally at students (from senior undergraduate to postgraduate) as well as practising scientists in the fields of evolutionary biology, ecology, physiology, functional morphology, developmental biology, comparative biology, paleontology, and beyond who are interested in how adaptive radiations are produced by evolutionary and ecological processes.

In the century and a half since Darwin's Origin of Species, there has been an ongoing--and often vociferously argued--conversation about our species' place in creation and its relationship to a Creator. A growing number of academic professionals see no conflict between Darwin's view of life and the Christian faith. Dubbed "theistic evolution," this brand of Christianity holds that God has used processes like Darwinian evolution to achieve his creation. But is that true? Can Darwin's mechanism of natural selection acting on chance mutations be reconciled with God's intentionality in producing particular outcomes? Does humanity represent the apex of his creation, or just an erasable and ephemeral signpost along a path still being revealed? Does theistic evolution permit God to intervene supernaturally in the workings of his creation? Can we as humans be made in the image of God if we are just one of the millions of products of evolution? Can we salvage concepts like freewill, meaning, purpose, or an eternal soul within theistic evolution? In this book, Wayne Rossiter assess theistic evolution, and whether or not it is consistent with Christianity and secular science. His conclusion is that it bears little resemblance to classical Christianity, and promotes a century-old understanding of evolutionary theory. Theistic evolution renders God a passive player in creation, so far removed and undetectable that he resembles a mere shadow of the Creator described in Christianity.
