There are two different approaches to study cultural change - evolutionary and revolutionary.

Evolutionary change is slow whereas Revolutionary change is fast.

When a culture is transformed rapidly and its values and meaning system undergo major and extreme changes then we say that there is a Revolutionary change. It can be initiated through political intervention, technological innovation, or ecological transformation.

In evolutionary change, people transform gradually and the changes come slowly through time consuming process like education has brought many cultural changes in social beliefs and people of society. It is based upon cognitive learning system.
