Human Hands Evolved for Fighting, Study Suggests
Human hands may have evolved their unique shape in order to better punch the living daylights out of competitors, a new study suggests.
The new findings, published today (Dec. 19) in the Journal of Experimental Biology, show that the clenched fist produces no more force than an open-palm slap, but protects the fingers better. Human's unique hand shape is one of only a few possible configurations that allow an organism to have both manual dexterity and the ability to brutally club opponents, the study reveals.
"Once hands are no longer used in locomotion there could have been many different ways to manipulate and many different ways to punch," said Milford Wolpoff, a paleo-anthropologist at the University of Michigan, who was not involved in the study. "A hand that does both is really limited in its morphology."
