Animals also have consensus

Psychologists from the University of Belfsat, Northern Ireland have just discovered, dogs, cats, parrots, even fish have left or right hand.

The study was conducted on many different species and yielded unexpected results. For the group of 42 cats, they found that females were usually right-footed, while the male was the opposite.

According to the researchers, this difference may be due to their different behavioral backgrounds. For example, in the way of hunting, how to take care of the parents, even the place of residence, influences them.

So do dogs, except those that are damaged or castrated. This suggests the possibility of hormonal effects on favorable treatment. Dogs often wag their tails to the right while resting and to the left when active.

Males are usually left-handed, while females are the opposite.

For parrots, they often lift objects with a dominant leg, not both feet.

With goldfish, how to avoid enemies allows them to use a special eye and brain to deal with the disaster. To test, you can place a similar object in the center of the aquarium. The way they swim represents the right side.

The frogs are different. They tend to prefer the right side. The evidence is that prey that enters the right view will cause them to react and release their bait blades faster.

Humpback whales use the right jaw to chew on their favorite prey, sand eel.

The difference brings many advantages, especially for people or left-handed / left-handed objects, in a multi-right-handed world.

According to New Scientist magazine, left-handed people have an advantage in many fighting sports like tennis, boxing ., because they often have unexpected attacks from the left.
