Evolution Of Societies

Gerhard Lenski, a sociologist, differentiates societies based on their level of technology, communication and economy: (1) hunters and gatherers, (2) simple agricultural, (3) advanced agricultural, (4) industrial.^[3] This is somewhat similar to the system earlier developed by anthropologists Morton H. Fried, a conflict theorist, and Elman Service, an integration theorist, who have produced a system of classification for societies in all human cultures based on the evolution of social inequality and the role of the state. This system of classification contains four categories:

• Hunter-gatherer bands, which are generally egalitarian.
• Tribal societies in which there are some limited instances of social rank and prestige.
• Stratified structures led by chieftains.
• Civilizations, with complex social hierarchies and organized, institutional governments.

Over time, some cultures have progressed toward more-complex forms of organization and control. This cultural evolution has a profound effect on patterns of community. Hunter-gatherer tribes settled around seasonal foodstocks to become agrarian villages. Villages grew to become towns and cities. Cities turned into city-states and nation-states.^[4]
