The classic view of evolution is a series of alternating and distinct steps. The first step is the generation of diversity through mutation; the second, natural selection. There is a growing awareness that in some cases these steps conjoin; for instance, the classic view breaks down when mutational changes alter the very machinery that generates diversity, giving rise to qualitatively different and interesting phenomena. The evolution and differ-entiation of a variety of mutation rates among individual genes in a genome and individual members of a population play key roles in the evolution of adaptive strategies and genomes.'-3 The spectra of mutations that arise are indirectly selected through conflicts between the requirement for pro...
