Bare-knuckle fights 'knocked faces of humans into shape'
Bare-knuckle fighting has left its mark on the human face, according to scientists at the University of Utah in Salt Lake City.
The transition in facial structure from apes to early hominins had been explained largely by the need to chew on nuts, however scientists have now devised an explanation based on the need for the face to be buttressed against the impact of flying fists, which had become a weapon.
The researchers also found that these changes in facial anatomy closely coincided with the ability of the early hominins to clench their fists.
