| Abstract: | The employment of insecticides raises the fitness of resistant insects relative to their suspectible competitors; antibiotic use applies selection pressure in favor of resistant strains of bacteria, lower limits on fish net mesh size raise the advantages of smaller adults and monoculture reduces the fitness of competing species or crop variants, thus reducing biodiversity. There are many examples of the unintended impact of human activity upon biological evolution, and often this evolution has economic importance. This study examines some of the principles involved and provides a preliminary analysis of the extent to which the economically optimal inducement of evolution differs from that arising when changes in selection pressures are not anticipated. |
