{ 1 } - we can never know what accords with evolution (because we can never see the whole picture).
{ 2 } - what accords with evolution isn't necessarily good.
{ 3 } - Ima would agree with the definition.

We could consistently imagine there being bad things that accord with evolution. So "good" doesn't mean "what accords with evolution."

The general strategy is this: if someone claims that "good" means "such and such" (where this represents some descriptive term), ask "Are things that are such and such necessarily good?" Since the answer is "no," the definition is refuted.
