How come we can’t control a lot of muscles that we technically are able to?

Question

For example, people who can wiggle their ears or raise one eyebrow, the body is obviously able to control those muscles. But for most people, they can’t do it from the start and had to practice overtime. Why are we not able to do it from the start? I understand it may be due to those muscles not serving much of a purpose compared to others, but we are still able to control them.

Answer 1

You don’t learn to control individual muscles. You learn to move body parts using a sometimes complex combination of muscles.
