Humans are born as a fighter?

Human hands evolved over time into a better fist. A biologist from Utah theorized that the human hand changed from generation to generation for punching.

Earlier, a theorist says, palms and fingers grow shorter, and the thumb grows longer over thousands of years, in order to allow humans to use the tools better.

As reported by NY Daily, David Carrier, a professor of comparative physiology at the University of Utah did not reject the theory, but he's adding a new theory. He said that evolution carrying human on the capacity needed to defeat the enemy without hurting themself.

Carrier and his research colleagues conducted a study to assess the effects of various types of blows, from a blow open palms, playful boxing, and actual full force boxing.

The results reported in the latest issue of the journal Experimental Biology shows, evolutionary changes in the form of a hand making a more effective weapon.

"Our study results suggest that humans may be 55 percent more powerful attack with fists, compared slap," said Carrier. He continued, while the hand into a fist, the body is also preparing to take a hit. This capability makes the body does not feel pain during the fight.

In addition, also made the same evolution of human jaw better prepared to withstand blows, which concluded that in fact, the human birth, prepared as a fighter. It was, said Carrier, actually disturbing. "It shows that in fact, man is a beast," he said. *** [EKA | FROM VARIOUS SOURCES | NEWYORK DAILY NEWS]
