Quizplus · Accepted Answer

The guppy behavior studies demonstrate all of these concepts. The rapidity with which natural selection can operate is shown by the observed changes in behavior within a few generations of being transferred between high and low predation sites. There are significant differences in behavior that have evolved between populations in response to different predation pressures. There are also significant differences in behavior that have evolved within populations due to predation stress.
