Aposematism

                     

(Warning coloration) 

    · Noxious and dangerous animals advertise their unfriendliness by bright, conspicuous colors.

    ·An example would be a Monarch butterfly and its caterpillar are both aposematically colored.

   ·The evolutionary argument is that the conspicuous coloration will be favored because noxious prey will be memorized by the predators with experience.

                ·  Predators and prey coevolved and the edible conspicuous prey was eliminated and the noxious conspicuous prey evolved.

•       The predators evolved by knowing what was edible and what was noxious.
