My nephew is very young. He can move his ears. I am ten years older than him, but I am not. Is ear movement related to age? Is this a unique specialty of children? That's not true. Ear mobility has nothing to do with age, ear mobility is a personal difference. Whether to move your ears or not is actually related to whispering in people's ears. Auricular muscle, as its name implies, is a muscle that can regulate ear activity. The muscles moving in the animal's ear can freely rotate the ear and change the direction of the auricle, thus achieving the purpose of collecting the sound in a specific area. In this way, the source and direction of sound can be identified, so as to predict the danger in advance and avoid and escape. Whether to give animals ears depends on their life and death.

However, with the evolution of human beings and the improvement of body tissues and organs, the body can stand upright, the neck can swing flexibly, and the field of vision is broader. It is no longer necessary to enhance hearing and perceive danger through the free rotation of the ear. Therefore, the root of human empathy gradually degenerates, no longer has functionality, and now it only plays the role of fixing auricle. Most people do not move their ears, but there are always exceptions. Some people are born to move their ears. Because their homologous roots will not completely degenerate, their homologous roots are naturally strong and developed, and they can pull the auricle under the control of nerves, so that the auricle can move simply and casually. These people have the special function of moving their ears.

The essence of ear-moving magic is actually the action of muscle pulling the ear. But only a few people have this magical ability. The swing of the ear is controlled by moving the ear muscles behind each of our ears. Some animals, such as cats or puppies kept at home at ordinary times, have muscular ears. For example, almost all animals have this "ear-moving power". Moreover, rabbits have muscular ears, and these animals can adjust their ears and rotate flexibly.

People also have active muscles in their ears. Why can't most people control their ears? Darwin's theory of evolution tells us that all human beings have evolved through evolution. Our ancestors were apes. A long time ago, our ancestors could shake their ears flexibly and hear the sound of the wind more sensitively. Only by maintaining this vigilance can we find the bad guys in time and find the bad guys who are trying to occupy their own territory. Or, in the process of fighting the enemy, you can slap your big ears and raise your momentum with a roaring voice to make the enemy afraid.
