“I've always been amused when mutations are raised to support evolution.”
I think you mean ‘explain.’
“By definition, and strictly speaking mutations are simply changes,”
That’s incomplete. Mutations are genetic traits that are NOT inherited from either parent.
Even the genes which are not mutated involve change. I get half of Mom’s DNA, and half of Dad’s, which makes me an original combination.
“however I can't think of any BENEFICIAL mutations.”
Dude, every year people take antibiotics and forcibly breed the germ population to spread the mutation of immunity to those antibiotics.
Every fucking year, germs mutate and survive the next round of antibiotics.
“Only mutations which cause a negative impact...”
Well, you’re an idiot. If that were true, then each year the flu would get easier to treat. Also every STD that sailors bring back from foreign ports.
“But as I understand it, evolution wants to say there are good mutations.”
People who study evolution say that there are mutations that are not lethal, thus improve the survival of that generation, and any that inherit that trait.
"I'm just not aware of any.”
ANd I’m not aware of any gods. You would not find my opinion any more valid than I find your ignorance on biology, huh?
“If you know of some, I really [sincerely] would be interested in reading about them.”
Every strain of penicillin-resistant disease.
