Classical evolutionism holds that the motivation of cultural evolution is single, and it will change after a long time. Just like animal evolution, all cultures in the world have to go through the evolution process from simple to complex and from low to high from low to high. This school believes that all cultures will go through a specific stage of development, from "ignorance" to "civilization". This theory is called "single line evolution". However, the new theory of evolution has emerged universal evolution and multiline evolution, gradually replacing the "single-line evolution". The new evolutionism abandons most of the classical evolutionism and keeps the fact that "human culture is constantly evolving". At the same time, it opposes the idea that the continuous improvement of human psychology is the driving force of cultural evolution, and thinks that "technology-economy" is the decisive factor of cultural evolution. Multiline evolution theory and universal evolution theory complement each other, which basically expounds the evolutionary fact that cultural evolution is the result of many aspects, and it can not bring about a unified situation; On the contrary, due to the complexity of motivation, the result is also complicated, which is bound to be a diversified and diversified situation.
