Evolution of societal organizations

How does a society organize?

A societal grouping may be disorganized. Such random groupings arise as crowds in busy areas. A crowd behaves like a "gas" composed of individual that react to events. Some emergent patterns can develop from the autonomous behavior of each individual.

Structured organizations are:

family -- the start of kin organizations pre-date history
hierarchical -- developed 1000s of years ago and used in religions, military, and government
corporate -- developed 100s of years ago and used for businesses
market -- developed 100s of years ago and used for consumers
network -- developing now?

Family structure may have been one reason why humans evolved big brains. The evolutionary advantages are large for knowing and remembering the many inter-personal relationships of a village. Instead of treating other members the same, if a person knows the other person, then both might benefit more than would occur in anonymous interactions.

The transition from "family" to "hierarchical" is thought to be due to the need to organize large militaries.

A "market" is very useful for price discovery and dealing with large numbers of buyers and sellers.

Is the internet producing a new societal organization, the "network"? People build networks of relationships that transcend other organizations. Could this be the result of an electronic society?
