In most species, dancing is about banging. (when they dance of course) Some birds will dance to signal their fitness to a female, right before reproduction. And the rules can be pretty intricate too.

It probably is less of a signal in humans, though. But I can't say I haven't successfully mated a few times via dancing.

It's as much about banging as programming is: safe occupation, above average income, signalling good provider. Or any sport. Or any other activity if we start describing them that way. But if you join a social dance scene with that perspective, you're likely to just annoy lots of people. On average, they're not there for banging and have their own existing relationships. A cigar is sometimes just a cigar :-)

Sure. I aggree.
