How does society develop?

There are multiple models explaining the development of human societies. The evolutionary model using observations of other upper division mammals and anthropology indicates the societal development and structure is inherent to a species. This is because whales, dolphins, and primates (our evolutionary ancestors) live in societal units, just as humans do today. Other factors to societal development in humanity is socialization and normative values. Societies globally share similarities and differences due to these differentials.
