In a long term study by the evolutionary biologists Endler and Reznick, they illustrated the effect of predation on life history traits by studying guppies with different predators: cichlids and killifish. The killifish preys mostly on immature, smaller guppies and cichlids pursue mature, larger guppies. They noticed that in river portions with only killifish, the guppies were larger than in river portions with only cichlids. How did Endler and Reznick test whether these differences in life history traits were genetic?
