This book is a thorough re-examination of the "species problem", the continuing disagreement among biologists about how best to identify species and what constitutes useful and genuine biological divisions of groups and organisms. This book contributes to our understanding of the scientific issues related to the species concept through an exploration of the reality of biological diversity and of the mental processes behind the ways we recognize species, and how we establish typological categories generally. The text develops a theory of evolutionary groups (groups of DNAs that compete and share in genetic drift and adaptation), and revisits the major issues of modern phylogeny, systematics, and evolutionary biology through this framework.

In December 2004, the National Academy of Sciences sponsored a colloquium on a /Systematics and the Origin of Speciesa to celebrate Ernst Mayra (TM)s 100th anniversary and to explore current knowledge concerning the origin of species. In 1942, Ernst Mayr, one of the twentieth centurya (TM)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 Linnaeusa (TM)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 a /species,a and genomic approaches for understanding diversity and speciation.
