Abstract :

Regulatory selection is the most typical mode of natural selection responsible for the optimization of the regulatory systems of an organism. In addition to regulatory selection, stringent selection of pleiotropic mutants or recombinant forms with altered ecological potential operates in successful species during vertical evolution. Regulatory selection stabilizes alterations in the ecological potential, acting at intervals between larger regulatory genome alterations occurring at the boundaries between evolutionary phases. Fisher's adaptive model can be applied to regulatory selection. At each separate evolutionary phase, the selection coefficients in selected mutants decline gradually. At the final stage of the evolutionary phase, mutations with a minor selective advantage are selected. Hence, regulatory selection may be regarded as an alternative to the neutral evolution theory.
