Natural selection has favored biologically catalyzed mechanisms whereby toxic substances are removed from the biosphere. Such mechanisms will be arranged in linear arrays rather than in cycles; they tend to channel their products away from biogeochemical circulation into the exterior "abiotic" fluxes.
