KIN GROUPS can refer to a variety of social groups, such as CLANS, which are typically made up of families that share a common ancestor. CLANS are usually associated with a geographic area and have a shared history and culture. They often have a hierarchical structure, with a leader or chief at the top. KIN GROUPS can also refer to tribes, which are larger than CLANS and are typically composed of several CLANS. Tribes are usually associated with a particular region and have a shared language, culture, and religion.
