Some people are able to move their ears by pulling them with their facial muscles, which means that a certain nerve is more developed in these people, but most people cannot move them. Individuals, who have more powerful ear muscles, are able to pull the auricle under the innervation and cause the auricle to move at will. People evolved from animals, and in the process of human evolution, many features similar to those of animals were gradually eliminated because of the principle of using the inverse. It turns out that human ears are just as mobile as animal ears, and the fact that some people can move their ears is actually a reversionary phenomenon.
