Let's try to understand evolution theory in a simple manner . Charles Darwin's idea of evolution was connected to living things. Herbert Spencer was one of the first sociologists to put theory into the field of study. Society, like organisms, goes through many stages of growth, says Herbert Spencer, the man who came up with the idea of comparing society to a living thing. When Herbert Spencer wrote First Principles and Principles of Sociology, he talked about his evolutionary system for the first time.
People know that the theory of evolution says that simple organisms grew into more complex ones over hundreds of years, so we know that. Similarly, the evolutionary perspective says that civilization went through a lot of different stages before it became as complex as it is now. Because the evolutionary theory of society is based on the idea that society is like a living thing, the Organismic theory must be talked about. Organismic theory thinks of society as a larger organism that has the same structure and function as a single organism. It shows the same type of unit as a single organism, and it grows, matures, and dies in the same way as a single organism. Each person in society is a cell in the body. Associations and institutions make up the organs and systems. In Herbert Spencer's view, society has a young age, middle age, and old age and then dies.
In Spencer's view, evolution is based on three things: (a) that forces tend to stay the same; (b) that matter can't be destroyed, and (c) that everything moves in the direction of least resistance or greatest attraction. Spencer: "Evolution is the integration of matter and the dissipation of motion at the same time, during which matter moves from an undefined, incoherent homogeneity to a definite, coherent heterogeneity," he said. Spencer thinks that society is going through a similar process. It's going from "incoherent homogeneity" to "coherent heterogeneity." As a result, evolution is a never-ending process that moves from a simple existence to a more complex one.
There was no system or set of rules in prehistoric society, except for their incoherent or loose group groups. They came up with a "undefined, uncoherent" homogeneity as a result. Their experiences, realisations, and wisdom grew over time, but not as quickly as they did at first. They learned to live together and work together. There was a process of social organisation, a division of labour was made, and each person found a job that they excelled at. Everyone worked together in a well-planned and methodical way to reach a certain goal. Because of this, there was a state of 'clear, coherent heterogeneity.'
Spencer thinks that the transition from simple societies to more complex societies is the most important part of evolution. From the aggregation of some simple societies, compound societies grew into two- and three-fold compound societies. Trebly compound societies came from the aggregation of two- and three-fold compound societies, too. When people live together in groups, they form groups called clans or tribes. A simple society is made up of families, and when people live together in groups, they form groups called nations or states. People in the group get more powerful and have different jobs as they get bigger, so the structure of the group changes, as well.
