Why are cartoon characters mostly four fingers?

The phenomenon of cartoon characters with four fingers appeared very early, such as Mickey Mouse, Tom and Jerry we watched when we were young. But now some characters have five fingers. There must be a reason for this. Let's analyze it.

first of all, there is a saying to save costs. Because the early animations were all drawn by people by hand, and the hand is a relatively difficult part to draw, four fingers can correspondingly reduce a lot of workload, draw more conveniently and speed up work efficiency, so drawing only four fingers is undoubtedly a burden reduction. Disney revealed in the early days that drawing one finger less can save millions of dollars.

Secondly, the painting with four fingers is just a tradition. Most of the animated characters with four fingers appear in the animations in Europe and America. Many of the cartoon images come from animals, so after they are anthropomorphic, they still retain the shape of animals with four fingers, and the audience has adapted. Later, there were more paintings like this, and no one would deliberately change anything.

finally, according to the scientific basis of biological development. Most of the characters in cartoons are quadruped mammals, and the four fingers of quadruped mammals are normal, because some quadruped mammals do have only four fingers, and the fifth finger has degenerated. This explanation is reasonable.

With the development of science and technology, many cartoon characters now have five fingers, but there are still many roles of four fingers. Whatever the reason, as long as the public can accept it, I don't think four fingers and five fingers matter.
