Evolution usually involves some important or significant changes and development of a thing or phenomenon in a period of time, which may involve shape, function, nature, scale and so on. Evolution is usually a continuous, gradual and regular process, not a sudden and jumping change.
In nature and society, examples of evolution are very common. For example, in the long process of evolution, biological species constantly change their genes and environment, leading to the emergence of new species and biological forms; Human society is constantly evolving in economy, politics and culture, and new systems, concepts and technologies are gradually emerging.
In history, many important concepts, theories and ideas have been gradually developed through constant evolution. For example, Darwin's theory of evolution has experienced a long-term evolution and development, from the initial basic principles to later modern biological theories, constantly developing new concepts and viewpoints; For another example, the theory of modern physics has also undergone many evolutions, from classical mechanics to quantum mechanics, and then to relativistic physics, which constantly promotes human knowledge and understanding of nature.
The process of social evolution:
1. Social differentiation: In the process of social evolution, different classes, occupations and cultures began to differentiate in the originally homogeneous society. These differences may come from different reasons, such as the development of production technology, differences in geographical environment, differences in cultural traditions and so on.
2. Social stratification: With the intensification of social differentiation, social stratification began to appear. The gap between different classes in wealth, power and prestige is getting bigger and bigger, which leads to the inequality of social structure.
3. Social interaction: On the basis of social stratification, interaction and communication between different classes began. This includes economic exchange, political interaction and cultural exchange. Some of these interactions are conducive to social stability and prosperity, while others may bring contradictions and conflicts.
4. Social institutionalization: In order to solve the contradictions and conflicts in social communication, the society needs to establish certain systems and norms. These systems and norms can be legal, moral, cultural and other aspects, and they play a guiding and binding role in the behavior and thoughts of social members.
