Whaddya think if humans are (were?) to evolve that

against the ear (like you can do now with your finger)
thus acting as an 'eyelid' for your ear in case things get
too loud ?
I mean what the heck is it doing there now, eh?

I'm asking for forgiveness because it's the second PS :S.
How does the external ear exactly work? Perhaps it's part of this
