I initially parsed that as meaning something like "we're clearly not getting the mechanics of evolution across, since people in the comics [and by extension writers] are happy to treat it as something that can produce superheroes". But in context it actually seems to mean "let's create some superheroes to demonstrate the efficacy of evolution beyond any reasonable doubt".

Comic exaggeration, sure, and I'm probably supposed to interpret the word "evolution" very loosely if I want to take the quote at all seriously. But in view of the former, I still can't help but think that there's something fundamentally naive about the latter.

You know, in the comic books where super-powered mutants are real, no one seems to question the theory of evolution. Maybe we're going about this all wrong.

Hasn't it been pointed out here before that super-powered mutants are exactly not what we would expect from evolution?
