Acephalous Societies:Acephalous societies are those that lack a centralized political authority or leadership hierarchy, and are instead organized around more egalitarian, decentralized social structures.
Tribes:Tribes are a form of social organization larger than bands, typically consisting of several bands that share a common language, culture, and territory, and may have a more complex political and social structure.
Foraging:Foraging is the act of searching for and collecting wild plants, fungi, and other edible resources for subsistence, which is a key economic activity in band societies.
