Book Description
A readily comprehensible guide for biologists, field taxonomists and interested laymen to one of the oldest problems in biology: the species problem. Written by a geneticist with extensive experience in field taxonomy, this practical book provides the sound scientific background to the problems arising with classifying organisms according to species. It covers the main current theories of specification and gives a number of examples that cannot be explained by any single theory alone.

Book Description
Over the last two decades, the study of speciation has expanded from a modest backwater of evolutionary biology into a large and vigorous discipline. Speciation is designed to provide a unified, critical and up-to-date overview of the field. Aimed at professional biologists, graduate students and advanced undergraduates, it covers both plants and animals and deals with all relevant areas of research, including biogeography, field work, systematics, theory, and genetic and molecular studies. It gives special emphasis to topics that are either controversial or the subject of active research, including sympatric speciation, reinforcement, the role of hybridization in speciation, the search for genes causing reproductive isolation, and mounting evidence for the role of natural and sexual selection in the origin of species.

Book Description
Today many school students are shielded from one of the most important concepts in modern science: evolution. In engaging and conversational style, Teaching About Evolution and the Nature of Science provides a well-structured framework for understanding and teaching evolution. Written for teachers, parents, and community officials as well as scientists and educators, this book describes how evolution reveals both the great diversity and similarity among the Earth's organisms; it explores how scientists approach the question of evolution; and it illustrates the nature of science as a way of knowing about the natural world. In addition, the book provides answers to frequently asked questions to help readers understand many of the issues and misconceptions about evolution. The book includes sample activities for teaching about evolution and the nature of science. For example, the book includes activities that investigate fossil footprints and population growth that teachers of science can use to introduce principles of evolution. Background information, materials, and step-by-step presentations are provided for each activity. In addition, this volume: Presents the evidence for evolution, including how evolution can be observed today. Explains the nature of science through a variety of examples. Describes how science differs from other human endeavors and why evolution is one of the best avenues for helping students understand this distinction. Answers frequently asked questions about evolution. Teaching About Evolution and the Nature of Science builds on the 1996 National Science Education Standards released by the National Research Councilâ€"and offers detailed guidance on how to evaluate and choose instructional materials that support the standards. Comprehensive and practical, this book brings one of today's educational challenges into focus in a balanced and reasoned discussion. It will be of special interest to teachers of science, school administrators, and interested members of the community.

Book Description
In December 2004, the National Academy of Sciences sponsored a colloquium on "Systematics and the Origin of Species" to celebrate Ernst Mayr's 100th anniversary and to explore current knowledge concerning the origin of species. In 1942, Ernst Mayr, one of the twentieth century's greatest scientists, published Systematics and the Origin of Species, a seminal book of the modern theory of evolution, where he advanced the significance of population variation in the understanding of evolutionary process and the origin of new species. Mayr formulated the transition from Linnaeus's static species concept to the dynamic species concept of the modern theory of evolution and emphasized the species as a community of populations, the role of reproductive isolation, and the ecological interactions between species. In addition to a preceding essay by Edward O. Wilson, this book includes the 16 papers presented by distinguished evolutionists at the colloquium. The papers are organized into sections covering the origins of species barriers, the processes of species divergence, the nature of species, the meaning of "species," and genomic approaches for understanding diversity and speciation.

Book Description
In this provocative work, David N. Stamos tackles the problem of determining exactly what a biological species is: in short, whether species are real and the nature of their reality. Although many have written on this topic, The Species Problem is the only comprehensive single-authored book on this central concern of biology. Stamos critically considers the evolution of the three major contemporary views of species: species nominalism, species as classes, and species as individuals. Finally, he develops his own solution to the species problem, a solution aimed at providing a universal species concept worthy of the Modern Synthesis. This book will be of interest to philosophers of biology and of science in general, to historians of biology, and to biologists concerned with one of the most significant (and practical) conceptual issues in their field.

Book Description
Two human species have long existed, unrecognized in front of our very eyes. They are Homo sapiens patripolaris and Homo sapiens matripolaris. Their reproductive differences remain unnoticed. Yet, because they are two different species, when they cross-breed, their hybrid offspring are cross-wired to produce Dyslexics, Homosexuals, Pedophiles, and Schizophrenics. This book contains published questionnaires that enable you to find your hemisity, your familial polarity, learn to which species you belong, and what type of "normal" or hybrid you are. Unrecognized, life-affecting differences in courtship and child rearing exist between the two species. This is the topic of Familial Polarity whose ancient existence and influence upon history you can confirm for yourself. Ignorance of familial polarity is a major source of multiple levels of global conflict.
