I was just reading the site (that Ivan Seeking referenced) about the "sixth extinction", and it got me thinking about something. We know that all animals strive for their own survival and for the survival of their species, right? Well, in this struggle for survival, a very "successful" (if you define "successful" in terms of ability to survive and adapt as a species) species has evolved, and it is now that very species that holds the power to destroy itself and every other being on Earth. Now, this is surely not an "advantage", since it is merely (when looked at logically) the ability to destroy yourself, which is the opposite of how I previously defined "success", and yet this disadvantage has spawned from an amazing series of "successes". Is this supposed to be a vicious circle, or do we need to re-think our definition of "success"? Perhaps success is merely ability to get along with your environment, while continuing your own existence - in which case, Myotis Lucifigus (which are Microchiroptera (small, insect-eating bats)...I was just reading about them in another window) is infinitely more successful than Homo Sapiens. It's something to think about, especially when one wishes to hold anthropocentric beliefs, as are being discussed in this thread.
