Sarcasm and Survival

Sarcasm Seen as Evolutionary Survival Skill

It's also easy to imagine how sarcasm might be selected over time as evolutionarily crucial. Imagine two ancient humans running across the savannah with a hungry lion in pursuit. One guy says to the other, "Are we having fun yet?" and the other just looks blank and stops to figure out what in the world his pal meant by that remark. End of friendship, end of one guy's contribution to the future of the human gene pool.
