Human's snore. I doubt this is a new occurence over the last millenia. I find it hard to believe that for the past million years, no human ancestor has been a snorrer.
And yet, the sound of snoring is incredibly irritating to humans.
Could there be any evolutionary basis for these two facts?
One thing I could think of is perhaps snoring serves a purpose of making adult males seek out their own homes and families.
A male child may be inclined to be so annoyed by his father's snoring that he goes off into the world to seek his fortune.
If it didn't serve a useful purpose, surely it would have died out, simply because other humans would be so annoyed by snoring that they would murder snorrers in their sleep and hence reduce the genes for snorring.
