In your own words. It is not enough to note differences or interesting behaviors in the cultures you are describing. Besides describing them you should be explaining them and attempting to understand the basis for the different behaviors and how they function as part of the culture you are describing.  Why do their behaviors work and exist in their culture? Use anthropology concepts to describe and understand behaviors as parts of cultural institutions (religious, economic, political, and social).  How do the behaviors relate to and support these institutions in the culture you are describing and discussion?  How can change occur so that the institutions are still maintained and the culture continues to survive?
