Humans Most Aggressive on Earth
A study published in the Journal of Experimental Biology has stated humans to be among the most aggressive and violent species on the planet with researchers of the study assuring that human hands have evolved for punching, fists and fight, and not just for manual dexterity.
"With the notable exception of bonobos, great apes are a relatively aggressive group of mammals", lead author David Carrier told Discovery News. He added that several primatologists argue that chimpanzees are the most aggressive apes but he has showcased evidences, which he said, are clearly confirming that humans are substantially more violent than the chimpanzees.
He explained that chimpanzees physically batter each other more frequently but incidences of rapes, torture, violence, slavery etc are higher in humans than the animals, which clearly states humans to be the most violent animal on the planet.
Carrier and his co-author Michael Morgan, a medical student, recently conducted three experiments: One, in which they analyzed the hardest punching of men aged from 22 to 50, which delivered the peak stress of 1.7 to 3 times greater than the slap, to the bag, whereas during the second and third experiments they tried to determine the effect of buttressing from the human fist, which they found, increased the stiffness of the knuckle joint fourfold along with doubling the ability of the fingers to transmit punching force.
