Why do people snore? I don't mean "how", or what happens physiologically, but rather - why?
Genetically speaking, wouldn't a sleeping animal, making a lot of noise, tend to be eaten? Thus reducing their contribution to the gene pool?
(And some people can really raise the roof when they are sleeping off a night of drinking, say... )
Or maybe I have it backwards - don't poke the sleeping bear? Does the snoring scare away other animals?
Either way, how would snoring be selected for genetically? Because it seems that a lot of people do snore, it's not just an occasional anomaly...
