"As an alternative, we suggest that the hand proportions that allow the formation of a fist may tell us something important about our evolutionary history and who we are as a species," Carrier adds. "If our anatomy is adapted for fighting, we need to be aware we always may be haunted by basic emotions and reflexive behaviors that often don't make sense – and are very dangerous – in the modern world," says biology Professor David Carrier.
Carrier and his collaborators not only have argued our hands evolved partly for punching but that the faces of human ancestors, the australopiths, evolved to resist punching – and that human faces became more delicate as our violence became less dependent on brute force. The new study sought more experimental evidence for his theory using nine male cadaver arms purchased from the university's body donor program and from a private supply company.

That human opposable thumbs and hands were evolved to take a firm grip around the neck of a club as one hand strikes his\her's potential mate to submission while the other holds the reins of the raptor one is riding.

My hands evolved so I can play the piano and touch myself inappropriately.

Well, of course. These skills are very important for Clubbing, Mate Toss, and Dino Race events. How else does a caveman get a rock medal?
