Most people on the planet are right-handed. What about animals? They also have right and left paws, but is there a preference separation among them, which ones are more comfortable to use?
Where do right-handed and left-handed people come from?
The brain of humans and animals is divided into two hemispheres: left and right. In humans, the first is responsible for rational thinking, literacy in speech and writing, and the ability to analyze and perceive the world through vision and hearing. The second specializes in creativity, imagination, intuition, drawing.
For each creature, a particular hemisphere prevails over the other. And if it is left, it becomes right-handed, if right - left-handed. It depends on what kind of limb most actions will be performed.
Interesting fact: Left-handed people are more likely to be creative because of the developed right hemisphere. Now scientists are trying to establish what differences are in animals, depending on the leading limb.
Are righties and lefties among animals
Yes, the animals also show a predominance of hemispheres and the presence of a leading limb. The following facts are currently known:
- among cats, 40% have no separation and use their paws evenly, 40% are right-handed, 20% are left-handed;
- some types of birds, while sleeping, stand on a certain leg or hold on to a tree branch, hanging head down;
- almost all kangaroos are left-handed;
- parrots have not only a leading limb, but also an eye, turning them towards the object they want to see;
- many species of monkeys begin to move from a certain paw, they also often take objects and make gestures;
- whales during hunting often turn on their left side;
- dogs also have leading paws, with a chance that the dog will turn out left-handed or right-handed about 50 to 50;
- worms also have a predominant side, on the basis of this, the direction in which they will dig a passage under the ground is determined, if necessary, turn.
Almost any creature has leading limbs or an area that is more often involved in various actions.
Among animals, there are also lefties and righties. The definition of the leading limb depends on the prevailing hemisphere of the brain or other characteristics of the body.
