You Know What Hank, You're Not Blaming You Say Biology Isn't the Problem

Hank: I think that maybe it was our own doing that we selected this trait of having thin, you know, more colorful lips either because it was helpful for communication to be able to read lips or because we just thought they looked good. Dumb humans thinking that useless things are beautiful is the problem. And now well, and this isn't even a human thing either. This happens all the time where you like like sexual selection ends up creating just ridiculously useless traits. They're lovely, but ridiculous. John mentioned that Hank is on a journey of meaning. Can you expand upon that?
