The tiger will have a king on its head. Why?

There is a lot of artificial attention. Tigers live in a plant with a lot of yellow grass. In order to facilitate hunting, skin color and patterns gradually change, and the word "Wang" on his forehead is just a coincidence. In fact, most of our impressions of the word "Wang" on the tiger's head come from artistic creation.

Because of the understanding of the tiger in China folk tradition, artists use the word "Wang" to represent the pattern on the tiger's head, which is not only convenient for creation, but also artistic. Why not?

What's more, most of our understanding of evolution is limited to the theory of "natural selection". But the theory of natural selection can't represent the whole of biological evolution.

In some species with small effective population, the effect of natural selection on some weak beneficial or harmful traits is very limited.

To what extent, the benefits or disadvantages brought by a gene or trait are so small that they can be fixed, that is, whether they can be passed down or occupy a certain gene frequency in the population does not depend on the results it brings, but on random effects, that is, the luck of it (gene or trait). Therefore, if we really want to explain the pattern on the tiger's head from the perspective of evolution, it can be divided into two parts.

Why do tigers have patterns? Perhaps in ancient times, tiger stripes played a protective role and were preserved through natural selection. In addition, the pattern characters are lucky and have survived.

Don't use an imposed view to explain that it is a fact. The pattern on the tiger's head is just similar to the word "Wang". People give it a certain meaning after seeing it, which has nothing to do with natural selection.
