Unformatted text preview: cichlid pools were put in the pools with killifish as the predator. Over thirty to sixty generations the transplanted guppies grew 14% proving Endler and Reznicks theory about natural selection resulting from the habitat in where organisms live. <P>Endler and Reznick tested a hypothesis claiming that individuals adapted to changes in the environment. They proved this and that natural selection can occur more rapidly. They performed this experiment by transplanting guppies into pools containing different predators. Several generations show the changing rate of growth and age of maturity. The guppies that were transplanted into the killifish pool from the pike-cichlid pool grew and matured earlier compared to control groups. A conclusion was drawn that the change in predator resulted in a change from the guppies leading to a longer and more productive life. The traits most favored became the dominant traits in the guppy population in the tested pool....
