One topic of interest to toxicologists, particularly ecotoxicologists and ecologists is the potential for rapid evolution. Populations that evolve in a few generations rather than over hundreds of thousands or millions of years. Sometimes the pressures are naturally occurring, food availability, for example. But, there is increasing evidence that living things from invertebrates to vertebrates evolve in response to human-induced changes in their chemical environment. The following pages will highlight these studies.
