Human Aggressive Behavior Could Be Chemically Induced

You may not be responsible for aggressive behavior. New research shows that it could be caused by a chemical that strongly influences what you do, a chemical that you are not aware of.

The Longfin squid lays its eggs each year in warm shallow water. Eggs are coated with a protein pheromone. When a male squid gets close to the eggs the chemical is absorbed and the sea creature attacks any other male squid in close proximity.

It was thought that the cause of human aggression was in the brain which interacts with the body's physiological structure. This is now brought into question. Squid are complex, like humans. A similar protein pheromone is found in human seminal fluid.

The Dung Beetle Is the Strongest of Them All

Who's the strongest pound for pound? That little bug upon the ground!

Scientists have worked out which creature is the strongest. It is a dung beetle, Onthophagus taurus. This tiny bug can pull 1,141 times its own body weight. For a human to equal this he/she would have to lift 80 tonnes, equivalent to six trucks.

The dung beetle had to be extremely fit and healthy to accomplish this feat. Putting them on poor diets before a test reduced the amount they could pull. Apparently, they have to be strong because of their lifestyle. A male digs a deep hole under a dung pat where he mates with a female. If another male enters the tunnel the two males will fight a furious battle by locking horns until one is pushed out. The more weight a male can pull the more likely he is to win the fight and be able to mate, thus passing on his genes for high strength.

Some male beetle don't seem to compete with the large aggressive males. They are born smaller and weaker. When they were fed more they still did not take up the fight, but their testicles became larger. This enables them to mate more often taking advantage of larger males who let their guard down.
