90% of people are right-handed, and what about animals?

It is estimated that 90% of people in the world are right-handed, left. And animals, do they have any side agreement or not?

To find solutions, many groups of scientists have conducted research on dogs, cats, birds . and realized many interesting things.

Kitty

In 2009, psychologists from Queen's University (UK) studied 42 cats of 21 males and 21 females in order to find out whether cats favor left limbs or right limbs.

As a result, they found that although they can use both limbs in many simple challenges, there are those who often use a limb with difficult challenges.

Specifically when asked to take tuna out of the jar, 21 females use the right foot, while 20 of the 21 males use the left foot, the other uses both legs.

Good dog

A group of scientists from the University of Adelaide (Australia), led by team leader Dr. Luke Schneider, conducted research on 73 dogs, the results were quite complicated because 37% showed they had no agreement, 34% left, 29% right on the right.

However, in this study, the scientists put forward a dog's opinion that is related to their response to strangers.

In particular, dogs do not usually agree on any side. And the left-handed dogs are more likely to be "angry" with strangers.

Horse house

According to a study in 2005, horses under 4 years of age often use the right nose to smell.

In addition, French researchers also showed that horses in this country tend to use "favorable" eyes when looking at strange objects and "pros" that are related to emotional factors.

Specifically, horses with a higher emotional index will use their right eye more.

Chimp

A study conducted in 2010 at Chimfunshi Nature Reserve (Zambia) showed that 86% of chimpanzees have dominant hands, of which 48% are right-handed and 38% left-handed.

In particular, right-handed chimpanzees are often female.

Researchers also argue that having the right hand helps chimpanzees to make more complex requirements in life more complicated.

Bird

A study of the brain and behavior of birds shows that thrushers are often used to using one leg to grab objects, such as fruit. In it, the thrush bird is usually on the left.

Together, a study with Gymnorhina tibicen showed that they used both left and right eyes when reacting to each hazard. However, the bird uses 85% of the left eye when withdrawing from the enemy.

In contrast, when approaching a certain object, 72% of these birds use the right eye.

Fish

A study was carried out in 2013 with the Australian grouper species to find out the correlation between the "eye" of the fish and the position of the fish in the herd.

First, the team categorizes groups of fish that are left-handed, right-eyed, both or not by giving them a view in front of the mirror to see the reaction when they see themselves.

After that, the group will give a group of 4 fish to swim together and draw a remark that right eye fish often swim to the left edge of the herd. In contrast, fish that tend to use the left eye often swim to the right in the flock without swimming on the edge.
