Is it a miracle that people with moving ears?

Ear movement is the movement of head muscles.

In fact, they all moved back. You can practice.

The muscles in people's ears have degenerated.

It turns out that the muscles at the root of the ear are a kind of movement that makes the ear rotate, so as to monitor the surrounding sounds at any time to ensure its safety. However, with the increase of human walking upright and neck flexibility, we can find the surrounding dangers better and faster, so the ear muscles of apes (early humans) gradually degenerate.

From time to time, a very correct theoretical explanation is used, that is, Kamala dropped out of school by using waste, but she didn't use it very much, and the result was degraded.
