"Evolution: Components and Mechanisms" introduces the many recent discoveries and insights that have added to the discipline of organic evolution, and combines them with the key topics needed to gain a fundamental understanding of the mechanisms of evolution. Each chapter covers an important topic or factor pertinent to a modern understanding of evolutionary theory, allowing easy access to particular topics for either study or review. Many chapters are cross-referenced.

Modern evolutionary theory has expanded significantly within only the past two to three decades. In recent times the definition of a gene has evolved, the definition of organic evolution itself is in need of some modification, the number of known mechanisms of evolutionary change has increased dramatically, and the emphasis placed on opportunity and contingency has increased. This book synthesizes these changes and presents many of the novel topics in evolutionary theory in an accessible and thorough format.

This book is an ideal, up-to-date resource for biologists, geneticists, evolutionary biologists, developmental biologists, and researchers in, as well as students and academics in these areas and professional scientists in many subfields of biology.
Discusses many of the mechanisms responsible for evolutionary change Includes an appendix that provides a brief synopsis of these mechanisms with most discussed in greater detail in respective chaptersAids readers in their organization and understanding of the material by addressing the basic concepts and topics surrounding organic evolution Covers some topics not typically addressed, such as opportunity, contingency, symbiosis, and progress

The idea of "biodiversity" has become increasingly important for those who wish to preserve and protect the varieties of life on Earth. While most works on biodiversity look at only three components-the diversity of genes, of species, and of ecosystems-Understanding Biodiversity examines the diversity of life in all of its manifestations. The living world is diverse in many ways. Animals and plants vary greatly in their size and shape, in their behavior, in how they reproduce, in how they sense the surrounding world. Understanding Biodiversity argues that there are many ways in which biodiversity has an intrinsic value - for humans, and for the living world as a whole - and that biodiversity should be better understood and appreciated by everyone, not just those in the scientific community. Only through such comprehension and appreciation will we come to value and protect biodiversity more than we do now. Humanity can only gain from such an expanded view. In addition to discussing the importance of understanding biodiversity, the author provides examples and explanations of the variety of diversities: Diversity "Within" Species Diversity "Above" the Species Level Genetic Diversity Diversity of Ecosystems and Ecological Interactions Four Billion Years of Temporal Diversity Morphological Diversity Metabolic Diversity Sensory Diversity Reproductive & Sexual Diversity Life Cycle Diversity Behavioral & Cultural Diversity

You'd think that Harry Simmons - now the proud father of twins - would be ready to give up dangerous assignments and settle down to just being an insurance investigator. But no: first he barely escapes being killed in an explosion on a mysterious floating bordello in Seattle's harbor - where he's found the very dead body of the mayor's wife; next, he's knocked unconscious by a flying piece of Chihuly artwork; then he's shot at by an unknown assailant near the Burke-Gillman trail, probably the same miscreant who nearly offs him in the QFC supermarket parking lot, also hitting an attractive young Coast Guard ensign who has seduced Harry. Somebody obviously objects to Harry's nosiness. Likely the man who has raped and murdered eleven Jewish women for their blood. Or maybe it's the guy who's hired four Sicilians to assassinate a group of Russian mobsters innocently drinking coffee in the Crossroads Mall. You can be sure that Harry, Arnie and Jessica will sort it out eventually.
