Among organisms, higher organisms generally have powerful effector organs and thus reside at the upper level of the food chain, while lower organisms generally have poorer effector organs and reside at the lower level of the food chain. The same is true of human beings, those who have more tools can be in the upper class, and those who have less tools are in the lower class. In human competition, the upper class has advantage, that is, the class that holds the advanced organization has advantage, and can occupy upper level resources. Therefore, in the evolution of human beings and social organizations, natural selection also has a preference for evolution.

In ancient times, the hereditary hierarchy was generally practiced, so that the descendants of the upper classes were also at the top. However, there is a significant difference between humans and animals or plants, the genetic material of the offspring of animals and plants is exactly the same as that of their parents, while the inheritance of humans is incomplete. The inheritance of animals and plants is completed before the birth of the offspring once for all, and the genetic process of humans can continue until the death of the offspring, that is, lifelong education. Therefore the genetic integrity is related to the life activities of the offspring, that is to say, studiousness can master more knowledge and increase ability. Moreover, the source of genetic material obtained by human offspring is not limited to parents, so that the offspring of the lower class can become the upper class, and the hereditary status of the hierarchy is constantly challenged. The lower class of the common people also dare to say, “Is the emperor appointed by heaven？” the concept of natural human rights can be supported by the majority of people.

3.2.3 The Principle of Social Selection, Survival Struggle and Generalized Evolution of Cultural Creative Idea

Culture is the whole acquired trait of human beings, including all human innovations in history and in the future. Cultural creative idea is content of culture. Science, religion and art are all cultural creative idea. However, the term cultural creative idea emphasizes the new creation of human beings. Human social organization is a group of people with responsibility, rights and interests, and it is a kind of human civilization. So the principle of natural selection, survival struggle and generalized evolution of social organization is an application of the principle of natural selection, survival struggle and generalized evolution of cultural creative idea. But cultural creative idea is often not exclusive to one organization or one group of people. There is a lot of variation in organizations and people, and these variations include cultural creative idea and human biological variations..
