Rudolf Raff is recognized as a pioneer in evolutionary developmental biology. In their 1983 book, Embryos, Genes, and Evolution, Raff and co-author Thomas Kaufman proposed a synthesis of developmental and evolutionary biology. In The Shape of Life, Raff analyzes the rise of this new experimental discipline and lays out new research questions, hypotheses, and approaches to guide its development. Raff uses the evolution of animal body plans to exemplify the interplay between developmental mechanisms and evolutionary patterns. Animal body plans emerged half a billion years ago. Evolution within these body plans during this span of time has resulted in the tremendous diversity of living animal forms. Raff argues for an integrated approach to the study of the intertwined roles of development and evolution involving phylogenetic, comparative, and functional biology. This new synthesis will interest not only scientists working in these areas, but also paleontologists, zoologists, morphologists, molecular biologists, and geneticists.

Animals and Human Society provides a solid, scientific, research-based background to advance understanding of how animals impact humans. As a resource for both science and non-science majors (including students planning to major in or studying animal science, pre-veterinary medicine, animal behavior, conservation biology, ecotoxicology, epidemiology and evolutionary biology), the book can be used as a text for courses in Animals and Human Society or Animal Science, or as supplemental material for an Introduction to Animal Science. The book offers foundational background to those who may have little background in animal agriculture and have focused interest on companion animals and horses. Animals have had profound effects on people from the earliest times, ranging from zoonotic diseases, to the global impact of livestock, poultry and fish production, to the influences of human-associated animals on the environment (on extinctions, air and water pollution, greenhouse gases, etc.), to the importance of animals in human evolution and hunter-gatherer communities. The volume introduces livestock production (including poultry and aquaculture) but also includes coverage of companion and lab animals. In addition, animal behavior and animal perception are covered. It can also function as a reference or recommended reading for a capstone class on ethical and public policy aspects related to animals. This book is likewise an excellent resource for researchers, academics or students newly entering a related field or coming from another discipline and needing foundational information, as well as interested laypersons looking to augment their knowledge on the many impacts of animals in human society. Features research-based and pedagogically sound content, with learning goals and textboxes to provide key information Challenges readers to consider issues based on facts rather than polemics Poses ethical questions and raises overall societal impacts Balances traditional animal science with companion animals, animal biology, zoonotic diseases, animal products, environmental impacts and all aspects of human/animal interaction Includes access to PowerPoints that facilitate easy adoption and/or use for online classes

Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of “primary” sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Franz Kafka, the author has very nicely narrated the story of Gregou Samsa who wakes up one day to discover that he has metamorphosed into a bug. The book concerns itself with the themes of alienation and existentialism. The author has written many important stories, including ‘The Judgement’, and much of his novels ‘Amerika’, ‘The Castle’, ‘The Hunger Artist’. Many of his stories were published during his lifetime but many were not. Over the course of the 1920s and 30s Kafka’s works were published and translated instantly becoming landmarks of twentieth-century literature. Ironically, the story ends on an optimistic note, as the family puts itself back together. The style of the book epitomizes Kafka’s writing. Kafka very interestingly, used to present an impossible situation, such as a man’s transformation into an insect, and develop the story from there with perfect realism and intense attention to detail. The Metamorphosis is an autobiographical piece of writing, and we find that parts of the story reflect Kafka’s own life.
