Just a thought

I had a particularly frustrating trip home from work the other day. I use public transit as many people do and I'm sure those of you who do will agree that there are days where it seems everyone around you just might be the dumbest person alive. That thought crosses my mind often. This feeling is usually compounded after a particularly rough day at work and this was one of those days.
Maybe a day of dealing with assholes & stress makes you more sensitive to the minor stupidities of the general public?
The whole idea of a "herd" mentality, in my opinion has some validity. Next time you are on the subway, watch the people as they enter or exit the train and watch for that 'stunned' look on their faces. Sort of seems like they just came out of a coma and have no clue where they are or what they're doing but as long as they huddle close to the others they'll be ok.
Then there are the ones who seem to be more or less coherent and lucid but they lumber around as though they are completely alone. They'll box you in a corner, whack you with a bag or backpack, burp, fart whatever. Oblivious to their surroundings.
Well. My thought was this: If you took all of these people and isolated them, say on an island somewhere. Would they eventually devolve? I don't think devolve is actually a word. You can't evolve backwards but can you evolve full circle?
Would this wonderful island eventually be populated by primates? The culmination of breeding and reduced mental capacity defying the forward momentum of human evolution? A place where they can embrace their regressive genes and say FUCK YOU EVOLUTIONARY ADAPTATION!in their weird monkey language as they fling poo at each other.
I say yes.
That is all.
