Not really the subject question but...rats love to be tickled and scientist have found (using ultra sonic vocalizations) that rats can laugh.

Many good points brought out in earlier posts.


An introduced species only temporarily upsets Nature's balance-- a new balance will eventually be achieved. In fact, Nature is always swinging back & forth in a dynamic balance, never poised perfectly still.


Rats fill an ecological niche, but, as Generalists, they can quickly fill other niches, and their's can be filled by others.


Evolutionary "fitness" refers to reproductive fitness. Traits like speed, strength or intelligence helps the species meet the reproductive goal, but are only ancillary. Dandelions are neither strong, fast nor intelligent, but Gesu, can they reproduce.


The most important role of Rats in Nature is their "generality" making them an excellent source of new mutations when the environment will eventually change drastically. It's highly unlikely the Panda Bear or Koala will be the species on which the ultimate survival of class Mammalia will depend.

Tell that to mosquitos, copepods, bacteria, or any of the most evolutionarily successful organisms on the planet. We like to think intelligence is important because we think we are intelligent and important. But time is the test when it comes to evolution, intelligence is overrated.
