Patrilineality, also known as the male line, the spear side [1] or agnatic kinship, is a common kinship system in which an individual's family membership derives from and is recorded through their father's lineage. It generally involves the inheritance of property, rights, names, or titles by persons related through male kin.
In anthropology, a lineage is a unilineal descent group that traces its ancestry to a demonstrably shared ancestor, known as the apical ancestor. [1] [2] [3] Lineages are formed through relationships traced either exclusively through the maternal line (matrilineage), paternal line (patrilineage), or some combination of both (). [4]
In many "classificatory" systems of kinship terminology, relatives far beyond genealogical first cousins are referred to using the terms for parallel and cross-cousins.. And in many societies, parallel cousins (but not cross-cousins) are also referred to by the same terms that are used for sibli
Nevertheless, graphs depicting matrilineal descent (mother-daughter relationships) and patrilineal descent (father-son relationships) do form trees. Assuming no common ancestor, an ancestry chart is a perfect binary tree , as each person has exactly one mother and one father; these thus have a regular structure.
Patrilineal primogeniture predominated in ancient times. The Laws of Manu state that the oldest son inherits all of the father's estate. [60] Since the Middle Ages patrilineal equal inheritance has prevailed in perhaps a majority of groups, [61] although the eldest son often received an extra share. [62]
Within the descent group patrilineal descent lines were hierarchically organized, with descent from elder brothers invariably ranking higher than descent from younger brothers. The oldest member of the senior line (da zong) was the group's leader and the sole person who could perform rituals honouring the group's deceased founder and chief ...
Sib is a technical term in the discipline of anthropology which originally denoted a kinship group among Anglo-Saxon and other Germanic peoples.In an extended sense, it then became the standard term for a variety of other kinds of lineal (matrilineal or patrilineal) or cognatic (i.e.,descended through links of both sexes) kinship groups.
The MRCA of a population by definition cannot be older than either its matrilineal or its patrilineal MRCA. In the case of Homo sapiens, the matrilineal and patrilineal MRCA are also known as "Mitochondrial Eve" (mt-MRCA) and "Y-chromosomal Adam" (Y-MRCA) respectively. The age of the human MRCA is unknown.
