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.

## Etymology

From Middle English linage, from Old French linage, from ligne, from Latin linea (“line”); equivalent to line + -age.

## Characteristics

A lineage is a descent group characterized by unilineal descent. This means that lineage membership is determined by tracing ancestry through either a single line (unilineal), either maternal or paternal, or through a combination of both lines (ambilineal). This differentiates lineages from other descent groups like clans, which may have a shared ancestor but lack the demonstrably documented or traditionally accepted apical ancestor from whom all members descend. There are three forms of lineage, matrilineage, patrilineage, and ambilineal.
In matrilineage, descent is traced exclusively through the maternal line. Children inherit lineage membership from their mother, and the lineage consists of a mother, her children, and her children's children who are all matrilineally related. The Minangkabau people of Indonesia, being a Jew in the Jewish religion, and the Khasi people of India are well-known examples of societies with prominent matrilineal structures.
In patrilineage, descent is traced exclusively through the paternal line. Children inherit lineage membership from their father, and the lineage consists of a father, his children, and his children's children who are all patrilineally related. Patrilineages are more common globally, with examples found in many cultures, such as much of South East Asia.
In ambilineal lineage, descent is traced through either the maternal and/or the paternal lines, usually meaning that the individuals choose whether to affiliate with their mother or their father's group, or both. Ambilineal lineage can be bilineal or bilateral. Ambilineal lineages are relatively rare in more under-developed societies, such as South East Asia, and very common in modernized societies, such as the United States and Western Europe.
In Bilineal lineage (also known as double descent), children are part of both their mother and their father's groups. This results in many more people in a lineage. Examples of bilineal lineage include the Yako people of Nigeria.
Lineages play a large role in social organization across cultures. They influence inheritance patterns, with property and titles often passed down within the lineage. In addition, lineages often have religious significance, with one's ancestorial history often determining one's religion and position in that religion. The structure of lineages also leads to stability, social obligations, and reciprocity among members, providing support networks and a sense of shared identity.
