This study draws on data from numerous sources that support the paradigm of natural hybridization as an important evolutionary process. The review of these data results in a challenge to the framework used by many evolutionary biologists, which sees the process of natural hybridization as maladaptive because it represents a violation of divergent evolution. In contrast, this book presents evidence of a significant role for natural hybridization in furthering adaptive evolution and evolutionary diversification in both plants and animals.

More and more data indicate that evolution has resulted in lineages consisting of mosaics of genes derived from different ancestors. It is therefore becoming increasingly clear that the tree is an inadequate metaphor of evolutionary change. In this book, Arnold promotes the 'web-of-life' metaphor as a more appropriate representation of evolutionary change in all lifeforms.

Molecular Systematics and Plant Evolution discusses the diversity and evolution of plants with a molecular approach. It looks at population genetics, phylogeny (history of evolution) and developmental genetics, to provide a framework from which to understand evolutionary patterns and relationships amongst plants. The international panel of contributors are all respected systematists and evolutionary biologists, who have brought together a wide range of topics from the forefront of research while keeping the text accessible to students. It has been written for senior undergraduates, postgraduates and researchers in the fields of botany, systematics, population / conservation genetics, phylogenetics and evolutionary biology.

This volume presents the newest findings on speciation, bringing readers up to date on species concepts, modes of speciation, the nature of reproductive barriers. Topics include the forces that drive divergence, the genetics of reproductive isolation, and hybrid zones.

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer, and viral recombination has long been marked by controversy between researchers holding different conceptual frameworks. Those subscribing to a doctrine of 'species purity' have traditionally been reluctant to recognise inferences suggesting anything other than a marginal role for non-allopatric divergence leading to gene transfer between different lineages. However, an increasing number of evolutionary biologists now accept that there is a growing body of evidence indicating the existence of non-allopatric diversification across many lineages and all domains of biological diversity. Divergence with Genetic Exchange investigates the mechanisms associated with evolutionary divergence and diversification, focussing on the role played by the exchange of genes between divergent lineages, a process recently termed 'divergence-with-gene-flow'. Although the mechanisms by which such divergent forms of life exchange genomic material may differ widely, the outcomes of interest - adaptive evolution and the formation of new hybrid lineages - do not. Successive chapters cover the history of the field, detection methodologies, outcomes, implications for conservation programs, and the effects on the human lineage associated with the process of genetic transfer between divergent lineages. This research level text is suitable for senior undergraduate and graduate level students taking related courses in departments of genetics, ecology and evolution. It will also be of relevance and use to professional evolutionary biologists and systematists seeking a comprehensive and authoritative overview of this rapidly expanding field.

With more than 5,000 works cited, Handbook of Avian Hybrids of the World is the greatest compendium of information ever published on hybridization in birds. Worldwide in scope, it provides information on all reported avian crosses, not only those occurring in captivity, but also in a natural setting (approximately 4,000 crosses are covered). This book is a basic reference, intended both for the serious birder and the professional biologist. McCarthy's work fills a need for reference material that takes into account the last half century of data. It will be of interest to workers in a wide variety of fields, ranging from animal behavior to genetics, ecology, zoology, and systematics. In fact, it will make fascinating reading for anyone interested in birds and the natural world.

This book describes the important role that the transfer of genes between organisms has played during the origin and evolution of humans, and the evolution of organisms on which the human species depends for shelter, sustenance and companionship.

James A. Shapiro proposes an important new paradigm for understanding biological evolution, the core organizing principle of biology. Shapiro introduces crucial new molecular evidence that tests the conventional scientific view of evolution based on the neo-Darwinian synthesis, shows why this view is inadequate to today's evidence, and presents a compelling alternative view of the evolutionary process that reflects the shift in life sciences towards a more information- and systems-based approach in Evolution: A View from the 21st Century. Shapiro integrates advances in symbiogenesis, epigenetics, and saltationism into a unified approach that views evolutionary change as an active cell process, regulated epigenetically and capable of making rapid large changes by horizontal DNA transfer, inter-specific hybridization, whole genome doubling, symbiogenesis, or massive genome restructuring. Evolution marshals extensive evidence in support of a fundamental reinterpretation of evolutionary processes, including more than 1,100 references to the scientific literature. Shapiro's work will generate extensive discussion throughout the biological community, and may significantly change your own thinking about how life has evolved. It also has major implications for evolutionary computation, information science, and the growing synthesis of the physical and biological sciences.

Featuring an introduction by Stephen Jay Gould, "Genetics and the Origin of Species" presents the first edition of Dobzhansky's groundbreaking and now classic inquiry into what has emerged as the most important single area of scientific inquiry in the twentieth century: biological theory of evolution. Genetics and the Origin of Species went through three editions (1937, 1941, and 1951) in which the importance accorded natural selection changed radically.
