In kinship studies, what does "lineage" refer to?

Lineage in kinship studies refers to a group that traces its ancestry back to a common ancestor, emphasizing the relationships and connections that are derived from this shared heritage. This concept highlights the importance of ancestral ties in various cultures, where individuals may identify and associate with their lineage for social, political, and cultural purposes. Lineage can influence inheritance, social roles, and the organization of social groups, as members of a lineage often share responsibilities and privileges. Understanding lineage is fundamental in anthropology, as it reveals how different societies structure relationships and organize themselves based on familial connections.
