Investigation of the evolution of the DNA sequences that comprise a small gene cluster in five closely related species of Drosophila shows that it evolves as a mosaic, with adjacent subregions displaying very different rates and types of evolution. It appears that local differences in the influence of selectional and mutational forces result in the formation of these distinct subregions.
