No one knows why humans have chins? Hmm, maybe I do...

"Humans are the only animal that have a chin, and no one knows why."  Well, I think know why.  Chins acts as a third hand to hold things against your chest when your actual hands are full or otherwise occupied in some sort of tool. Chins are very important for rudimentary tool use, or just lugging things from one place over short distances when your hands are full.
