The human face evolves to avoid injury

(researches) - Research evidence from the ancient people (who have walked with 2 limbs) shows that the human face evolves to minimize the possibility of injury when fighting.

Scientists believe that 5 million years of fighting to the end with fists left a mark on the human face. Evidence shows that, after the ancient ancestors of human species learned how to punch in bickering, human faces evolved to minimize the damage suffered.

Researchers have studied the bone structure of the servant (a male gibbon, standing on two limbs that lived 4-5 million years ago). They discovered the servant's face and jaw, which was often hit by the punches, the strongest.

The American researcher, Dr. David Carrier, of the University of Utah, said the proportion of servants' hands allowed a fist to be formed, which could turn a regular hand into a stick.

'If indeed, the evolution of the hand rate is related to the selection of combat behavior, then you can also hope for the fundamental purpose of evolution, face, to undergo evolution to protect yourself. it is free from injuries when punched '.

The study, published by Biological Reviews magazine, builds on previous research that shows that violence plays a more important role in human evolution than what experts admit.

'When modern people fight by hand, faces are always the main target,' said carrier Biologist. 'What we found was that the bones with the highest fracture rate in a fight were parts of the skull, which showed a rapid increase in strength. This bone also shows a huge difference between men and women. In other words, the faces of men and women are different because the skull parts of men are broken during a bigger fight. '

'Our research has shown that many anatomical features of large human monkeys and our ancestors - Hominin people have evolved to improve their combat ability.'

Dr. Michael Morgan, co-author of the study, a doctor at the University of Utah, said: 'I think our scientific research is right, well-grounded, and fills in the gap long in the The theory still exists about why our skeletal muscle structure develops that way. '

'Our research is on peace. We seek to discover, understand, and face the tendency of human violence and aggression. Peace comes from ourselves and we finally get peace by seriously interpreting ourselves and understanding where we originate as a creature. Through our research, we hope to be able to see our reflection and start the hard work of changing ourselves to be better. '
