I teach evolutionary psychology and show a scene from.Planet Earth where birds of Paradise dance for mates. Food's plentiful, so going "hey, girl. I can get food." Isn't an asset. They gotta do a silly dance to attract a mate in such a food-loaded environment, instead.
I guess you can spin that kind of stuff to poorly explain human behaviors, but from everything I've read and prepped, it's a very broad but innocuous field of psych, if relatively nascent.
