I came up with my most generalized definition of the fact and theory of evolution (not just biological evolution). I was so proud of myself, that I put it in my "signature". The first four words are the fact, the rest the theory.
Sometime people, here and elsewhere, get snooty when you use the term "evolution" for things outside of biology. I say "screw them".
Originally the "Biological Evolution" forum was the "Evolution" forum. The name change was made to exclude non-biological evolution themes.
