Is Evolution Just a Meme?

I think it's easy to think that evolution just stops because you're like, everything I get it now. But obviously it's kept it's been going on for millions of years and it'll probably keep on going. If we live as long as the dinosaurs, that would be pretty interesting. We might grow another arm. Who knows? who knows where humanity is going to be and like millions and millions of years. Probably not around.
