"Boxing" Hypothesis for the Origins of Bipedalism

Add this to the list of published ideas about the selective advantages of bipedalism.

In a PLOS One article Carrier reports that human subjects deliver more powerful punches from a bipedal (orthograde) posture than from a quadrupedal (pronograde) posture.  This might suggest that forelimb fighting among males competing for females is a selective pressure for bipedalism.

Maybe we can call it the Rocky Hypothesis?
