Peter Lutz, PhD, brilliantly traverses the major milestones along the evolutionary path of biomedicine from earliest recorded times to the dawn of the 20th century. With an engaging narrative that will have you turning "just one more page" well into the night, this book revealingly demonstrates just how the modern scientific method has been shaped by the past. Along the way the reader is treated to some delightfully obscure anecdotes and a treasure trove of rich illustrations that chronicle the tortuous history of biomedical developments, ranging from the bizarre and amusing to the downright macabre. The reader will also be introduced to the major ideas shaping contemporary physiology and the social context of its development, and also gain an understanding of how advances in biological science have occasionally been improperly used to satisfy momentary social or political needs.

Recent decades have witnessed an explosion of theoretical and empirical studies of sex allocation, transforming how we understand the allocation of resources to male and female reproduction in vertebrates, invertebrates, protozoa, and plants. In this landmark book, Stuart West synthesizes the vast literature on sex allocation, providing the conceptual framework the field has been lacking and demonstrating how sex-allocation studies can shed light on broader questions in evolutionary and behavioral biology. West clarifies fundamental misconceptions in the application of theory to empirical data. He examines the field's successes and failures, and describes the research areas where much important work is yet to be done. West reveals how a shared underlying theoretical framework unites findings of sex-ratio variation across a huge range of life forms, from malarial parasites and hermaphroditic worms to sex-changing fish and mammals. He shows how research on sex allocation has been central to many critical questions and controversies in evolutionary and behavioral biology, and he argues that sex-allocation research serves as a key testing ground for different theoretical approaches and can help resolve debates about social evolution, parent-offspring conflict, genomic conflict, and levels of selection. Certain to become the defining book on the subject for the next generation of researchers, Sex Allocation explains why the study of sex allocation provides an ideal model system for advancing our understanding of the constraints on adaptation among all living things in the natural world.

Geographic Variation, Speciation and Clines explores the origins and development of geographic variation, divergence, and speciation. In particular it is concerned with genetic divergence as it is usually found on continents, among groups of populations isolated only by distance. Although earlier writers on this topic considered the effects of geography and dispersal, intense geographic differentiation and speciation were thought to require complete isolation. Professor Endler shows how geographic differentiation and speciation may develop in spite of continuous gene flow. Following a review of the diverse and scattered literature on gene flow and population differentiation, the author discusses the relationships among gene flow, dispersal, and migration. He then summarizes the factors which limit the geographic extent of gene flow, and those which allow steep clines to develop in the absence of barriers to gene flow. His analysis draws on examples from the field, experiments, and single- and multiple-locus models. The mechanism and conditions for parapatric speciation are presented: steepening clines, development into hybrid zones, and the evolution of sexual isolation. In the final chapter the author considers the interpretation of natural clines and the associated geographic patterns of subspecies and species.

Human embryo research touches upon strongly felt moral convictions, and it raises such deep questions about the promise and perils of scientific progress that debate over its development has become a moral and political imperative. From in vitro fertilization to embryonic stem cell research, cloning, and gene editing, Americans have repeatedly struggled with how to define the moral status of the human embryo, whether to limit its experimental uses, and how to contend with sharply divided public moral perspectives on governing science. Experiments in Democracy presents a history of American debates over human embryo research from the late 1960s to the present, exploring their crucial role in shaping norms, practices, and institutions of deliberation governing the ethical challenges of modern bioscience. J. Benjamin Hurlbut details how scientists, bioethicists, policymakers, and other public figures have attempted to answer a question of great consequence: how should the public reason about aspects of science and technology that effect fundamental dimensions of human life? Through a study of one of the most significant science policy controversies in the history of the United States, Experiments in Democracy paints a portrait of the complex relationship between science and democracy, and of U.S. society's evolving approaches to evaluating and governing science's most challenging breakthroughs.
