Why can some people move their ears, some do not work?

Do you remember the "Big Ear Picture" that I watched when I was a kid? Large ears are matched with ears, cute.

If you look closely, it is not difficult to find that there are people in life like a picture, which can control your ears. This skill looks useless, but it can show off, because only a few people have this special skill.

So why can only a small number of people move their ears? Can I learn to "move their ears" by practicing?

You can learn from your ears!

Daniel J. Strauss, a professor of neuroscience and neurotic technology at the University of Salle Hospital in Germany, said that through a lot of training, you can also have this magic skill.

In a new study, the researchers provided visual feedback to the participants, allowing them to practice while observing their ear muscle activity while using the screen. In the end, this method can help them 'train' specific ear muscles. "

Strauss and the professors of the University of Sali and Missouri also conducted a study. Want to see if the ears of the participants will swing unconsciously under the stimulus of music. Straus believes that this unconscious ear movement is the basis for cultivating "moving ears".

Animals can also move their ears

In fact, in addition to humans, they can swing their ears at will to make themselves more focused to capture certain sounds.

These sounds allow them to avoid predators or help them find food.

The ears are erected like an antenna

The cat's ears are very flexible because each ear has 32 muscles, and human ears have only 3 pieces -ears, anterior ear muscles, and rear ears.

The outside of the ears of humans and other mammals is called the auricle. For animals that are good at hunting and easy to be hunt, the auricle often moves with the eyes, which allows them to capture "hearing or visual stimulation" more keenly.

So why can't humans like animals easily?

Strauss guess that some people retain the degenerate auricle orientation nervous system, so they can control their ears. But this skill is not a necessary skill for us to survive. Our ears are like a pair of sound radar, which can help the surrounding wind blowing. In the actual survival conditions, other species depend on the adjustment of 'sound radar' than us, so this ability is 'degradation' in the process of human evolution.

But this skill is very important for human ancestors who have lived millions of years ago. Because the humans at that time needed to use hearing to locate the threat around them, moving the ears could hear the sound more clearly.

Why can some people move their ears?

Straus believes that human beings' ears are not disappeared, but they are just "rigid".

Straus' research results show that although we all have the ability to swing our ears and can stimulate ears by sound, it is difficult to notice these actions.

Studies have also shown that although everyone has the potential to cultivate ears, some people have a clear bone and can swing their ears more easily.

I think your bones are clear, do you want to cultivate your ears?

So, who can move their ears?

//

First of all, these talented people often have strong muscles around their ears, so they can swing their ears more easily.

Secondly, if one of the parents can swing the ears, then you are more likely to practice this skill.

Of course, we also said earlier, as long as you practice hard and willing to spend time, you can easily become a "ears."
