Denying Evolution: Creationism, Scientism, and the Nature of Science

Denying Evolution aims at taking a fresh look at the evolution–creation controversy. It presents a truly "balanced" treatment, not in the sense of treating creationism as a legitimate scientific theory (it demonstrably is not), but in the sense of dividing the blame for the controversy equally between creationists and scientists—the former for subscribing to various forms of anti-intellectualism, the latter for discounting science education and presenting science as scientism to the public and the media. The central part of the book focuses on a series of creationist fallacies (aimed at showing errors of thought, not at deriding) and of mistakes by scientists and science educators. The last part of the book discusses long-term solutions to the problem, from better science teaching at all levels to the necessity of widespread understanding of how the brain works and why people have difficulties with critical thinking.

Phenotypic Plasticity: Beyond Nature and Nurture (Syntheses in Ecology and Evolution)

For more than two decades the concept of phenotypic plasticity has allowed researchers to go beyond the nature-nurture dichotomy to gain deeper insights into how organisms are shaped by the interaction of genetic and ecological factors. Phenotypic Plasticity: Beyond Nature and Nurture is the first work to synthesize the burgeoning area of plasticity studies, providing a conceptual overview as well as a technical treatment of its major components. Phenotypic plasticity integrates the insights of ecological genetics, developmental biology, and evolutionary theory. Plasticity research asks foundational questions about how living organisms are capable of variation in their genetic makeup and in their responses to environmental factors. For instance, how do novel adaptive phenotypes originate? How do organisms detect and respond to stressful environments? What is the balance between genetic or natural constraints (such as gravity) and natural selection? The author begins by defining phenotypic plasticity and detailing its history, including important experiments and methods of statistical and graphical analysis. He then provides extended examples of the molecular basis of plasticity, the plasticity of development, the ecology of plastic responses, and the role of costs and constraints in the evolution of plasticity. A brief epilogue looks at how plasticity studies shed light on the nature/nurture debate in the popular media.

Tales of the Rational : Skeptical Essays About Nature and Science

Engaging, compelling, witty essays that put in perspective some of the most fascinating scientific and pseudo-scientific claims of the 20th century. Includes discussions of: atheism, straw-man arguments, creationism, debating creationists and theists, evolutionary biology, Christian apologetics, critiques of modern science, the search for extraterrestial life, the search for the origins of life, chaos theory, and much more.

Phenotypic Evolution: A Reaction Norm Perspective

Understanding the process of adaptive evolution of phenotypes is a fundamental problem in evolutionary biology. It has been approached from the point of view of population and quantitative genetics, optimality theory, or developmental biology. In the last decade, there has been an explosion of research on phenotypic plasticity (the environmentally induced production of different phenotypes by a single genotype) as well as on the molecular details of development, reflecting the increased recognition of their importance in shaping phenotypic evolution. However, the "hardening" of the neodarwinian synthesis in the '40s led to the largely independent investigation of genetic, developmental nad environmental bases of phenotypic expression. As a result, these different perspectives have not been integrated into a satisfying cohesive view of phenotypic evolution. Phenotypic Evolution explicitly recognizes organisms as complex genetic-epigenetic systems developing in response to changing internal and external environments. The book can serve as a text for graduate-level courses and seminars on phenotypic evolution or evolutionary developmental biology, and as a supplemental text for evolutionary biology. The extensive references provide links to a wide variety of studies examining the diversity of phenotypes. The book will also be of interest to organismal biologists in general, including ecologists, developmental biologists, and systematists.
