All species 'evolve' via (not so random) mutation and natural selection. They evolve in order to adapt to the environment. They just don't evolve into other species.
There are, however, some creatures in the ocean that start life as a plant, then turn into a snake. But their 'species' doesn't change.
==They evolve in order to adapt to the environment.
No Temple of Darwin evo would agree with that statement. They believe that mutations are completely random, with no thought adapting to the environment. You are starting to sound like a theistic evolutionist!
