Hey, you know that little triangular flap of skin that

Whaddya think if humans are (were?) to evolve that
little flap so it can be completely and tightly pressed
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?
Tim.
It's called tragus.
We still have it for piercings to increase our attractiveness? So it
might be used for conservation of the species? :D
Btw. I guess the ears once were gills, at least it's one theory.
