text: is snoring of any evolutionary advantage? in prehistoric times wouldn't it have attracted predators? or would it have frightened them off.  you'd think there would be some evolutionary advantage for it not too have been selectively eliminated? snoring can be an advantage... for some people who snore, they do so in fight for air to pass through to air passageway to continue breathing... some people have swelled up or enlarged pharyngeal tonsils, so snoring ensures an unblocked airpassage way by exchanging air through the oral cavity...   ex: on the tyra (banks) show, big boy announce how his excess skin post-op of liposuction was almost suffocating his g/f in bed...but her body's response while she was sleeping was to autmatically start snoring to get air exchange when her nostrils were covered.
