Descendant

Kinship and descent is one of the major concepts of cultural anthropology . Cultures worldwide possess a wide range of systems of tracking kinship and descent. Anthropologists break these down into simple concepts which are commonamong many different cultures.

Descent groups

A descent group is a social group whose members claimcommon ancestry. A unilineal society (such as the Iroquois system) is one in which the descent of an individual is reckonedeither from the mother's or the father's descent group. With matrilinealdescent individuals belong to their mother's descent group. With patrilineal descent , individuals belong to their father's descent group.

In a society which reckons descent bilineally (such as the Eskimo system ), descent from both father and mother is equally important.

Societies can also consider descent to be ambilineal (suchas Hawaiian system ) where offspring determine their lineage throughthe matrilineal line or the patrilineal line .

Lineages, clans, phratries and moieties

A lineage is a descent group who can demonstrate their common descent from an apical ancestor . Lineages can be matrilineal or patrilineal, depending on whether they are traced throughmothers or fathers, respectively. Whether matrilineal or patrilineal descent is considered most significant differs from cultureto culture.

A clan is a descent group that claims common descent from an apical ancestor but cannotdemonstrate it (stipulated descent). If a clan's apical ancestor is nonhuman, it is called a totem . Examples of clans are Scottish , Chinese and Japaneseclans .

A phratry is a descent group containing at least two clans which have a supposedcommon ancestor.

If a society is divided into exactly two descent groups, each is called a moiety ,after the French word for half.

The nuclear family

The Western model of a nuclear family consists of a couple and theirchildren. The nuclear family is ego-centered and impermanent, while descent groups are permanent (lasting beyond the lifespans ofindividual constituents) and reckoned according to a single ancestor.

Kinship calculation is any systemic method for reckoning kin relations. Kinship terminologies are nativetaxonomies, not developed by anthropologists.

Legal ramifications

Kinship and descent have a number of legal ramifications, which vary widely between legaland social structures.

Most human groups share a taboo against incest ; which relatives are forbidden from marriage by the rules tend to vary widely once you move beyond the nuclear family.At common law , the prohibitions are typically phrased in terms of "degrees ofconsanguinity."

More importantly, kinship and descent enters the legal system by virtue of intestacy , the laws that at common law determine who inherits the estates of the dead in the absence of a will . In civil law countries, the doctrine of legitime plays a similar role, and makes the linealdescendants of the dead person forced heirs . Rules of kinship and descent have importantpublic aspects, especially under monarchies , where they determine the order of succession , the heir apparent and the heir presumptive .
