i must admit, i cannot further define evolution. it is beyond my ability.
You've yet to start defining it! You're opening brainstorm
evolution: the biological changes in living things
is so loose that it would include changes in blood sugar levels, antibody response to infection, getting goosebumps when you're cold and getting pregnant! Do you really mean that you consider these examples to be evolution? It's as bad as Behe's definition of science which takes in Astrology.
Given that this is obviously so much marsh gas, the causes of your "biological changes" are irrelevant, since you're using tem to list the causes of something that isn't evolution.
If you read around a bit on the intrnet, you may gather enough information to refine your definition, however, bear in mind that
so i feel it is true
doesn't really cut the mustard.
I think what Phat had in mind is what science defines as evolution.
Leave out the stars - that sort of evolution has an entirely different meaning and, as such, has an entirely different definition. You're trying to define the word not the concept.
