Lineage (anthropology)

Line of ancestors and descendants of a person

In anthropology, a lineage is a unilineal descent group that traces its ancestry to a demonstrably shared ancestor, known as the apical ancestor. Lineages are formed through relationships traced either exclusively through the maternal line (matrilineage), paternal line (patrilineage), or some combination of both (ambilineal). The cultural significance of matrilineal or patrilineal descent varies greatly, shaping social structures, inheritance patterns, and even rituals across societies and kinship groups.
