Why do population enjoy earlobes?
several reasons.
first it functions as a collector or sounds, it catch the sound and directs it to the outside conduit (external)
it also acts as a cushion for the ear and a protector, (for sounds and for trauma)
if you touch your ear at the middle front you will find a skin protuberance if you push it next to your finger this will close the ear and protect the external canal, contained by larger animal it also serves as a source of heat diffusion (to loose heat=elephants
To hang up things from
It's protects the outter layer of our ears, and so nought gets inside of our ears...
it's the course God made us=also to keep crisscross from blowing directly into ear and help dodge infections and keep sea out too
so they can here dummy! DUH!
it may help beside sound. near are more little hairs on your lobe than the cartilage. conceivably an ear doctor should answer though. i'm a creationist and i think God have a purpose for every single body part.
Perhaps they look more appealing next to them, as they seem to own no function but earrings.
