Look, what you are up against are folks who have confounded "evolution" with "change". They automatically argue that any change of any kind is, in fact, evolution.

No doubt they themselves will someday become parents who tell the other one that "the baby's diaper needs evolved".

Darwin himself seemed to like to reserve the word "evolution" as an explanation for the origin of species. I am sure if he meant "change" he'd have used "change" exclusively.

No, evolution is inherited change. That's precisely what Darwin meant, and precisely what we mean.

Darwin clearly and explicitly pointed to minor variations in finch beak size as constituting evolution. His crucial insight is that there is no qualitative difference between such minor variations and the gross differences between any two arbitrarily chosen organisms, only a quantitative difference.
