Describes the dynamics of evolutionary change at the molecular level, the driving forces behind the evolutionary process, and the effects of the various molecular mechanisms on the long-term evolution of genomes, genes, and their products, providing basic methodological tools for comparative and phylogenetic analyses of molecular data from an evolutionary perspective. In describing evolutionary phenomena and mechanisms at the molecular level, both mathematical and intuitive explanations are provided, as well as a large number of examples to support and clarify the many theoretical arguments and methodological discussions. Includes an appendix on basics of probability. Graur is associated with Tel Aviv University; Li with the University of Chicago. Annotation c. Book News, Inc., Portland, OR (booknews.com)
