Sarcasm Gene Selected Against in Neanderthal Hybrids?

Neurophysiologist Katherine Rankin talked about sarcasm being selected in our evolution back in 2008. Though I doubt that people who didn't understand sarcasm were negatively selected across ALL peoples (I have a few friends whose ancestors must have SURELY selected against it), I'm thinking that it might have something to do with selective sweeps across genomes.... i.e. What genes help individuals to understand tonal languages, and what genes help us to interact in cultures where where tone is used more for sarcasm, emphasis, surprise, etc... Of course neurophysiologist Katherine Rankin can't be blamed for getting that one bit wrong, though; she's only a neurophysiologist. Maybe if she had a real job like me singing Rolling Stones songs at the beach bars she'd know that about sarcasm...
