    Then suppose circumstances change so that spot
         provide more of an advantage. Over time the species evolves an elaborate
         biochemical mechanism for spots that allows the species to survive
         effectively in this new environment. Next suppose the environment changes
         back so that drab grey is now more effective. Organisms can go back to
         drab without unevolving the entire mechanism for spots. Instead they can
         just have point mutations that disable the spots. Then if the environment
         changes again so that spots are better, instead of re-evolving the whole
         spot system again, all that is necessary is that a few individuals lose the
         point mutations preventing spots from being expressed. This means that
         spots can reappear much more quickly the second time than they did the
         first time.

         So my question is, are there any real examples of this occurring in
         nature? Is there a term that is used to describe this phenomenon?

    Reminds me of those cowboys Dace mentioned - adapting back and forth to splice cultural and political memes into total mayhem. This 'oranism' constantly changes spots, yet keeps the grey area ( media). Evolution made easy? I call it 'Errorism" Peace B
