Similar to the development of children from appearance and color to older children, they can be classified according to concepts. For example, if they know the concept of "food", no matter what kind of vegetables they look like, they should be classified into one category.

The earliest method is to identify and distinguish species according to phenotypic characteristics, and to classify them step by step according to the degree of phenotypic similarity, so as to establish a classification system that is easy to retrieve. This is the principle of phenotypic classification. However, the problem of phenotypic classification is that it is difficult to reveal the essential laws of things.
