Kinship & Descent

What Is Kinship?• Kinship is a relationship between any entities that

share a genealogical origin (biological, cultural, or historical).

• Kinship is the most basic principles for organizing individuals into social groups, roles, categories, and genealog (important for production, politics & religion).

• One’s kinship status, determines these rights and obligations.

• Kinship is especially important in societies where institutions such as a centralized government, a professional military, or financial banks are absent or ineffective.

Functions of Kinship Groups

• Vertical function: provides social continuity by binding together a number of successive generations

• Horizontal functions: solidify a society across a single generation typically through marriage.

– Maintaining the integrity of resources that cannot be divided without being destroyed.

– Providing work forces for tasks that require a labor pool larger than households can provide.

– Rallying support for purposes of self-defense or offensive

attack.

Yoruba Egungun Dancer – Vertical Function

• The Yoruba of West Africa commemorate family ancestors in the form of masked dancers who become possessed by the spirits of the dead to commune with their descendants.

Kinship Diagram - EGO

• Relationships are traced through a central individual labeled the Ego.

• The various elements are joined to produce a kinship diagram.

Review of Terms

• Consanguineal kin:

• Affinal kin:

Are relatives by blood, as determined by the local socio-cultural system.

Are relatives acquired by marriage either from the:

• Family of origination or the

• Family of procreation

Identify the Ego’s relatives?

• Can you identify all of Ego’s relatives below?

Lineal & Collateral Kin• Lineal kin: are

either direct ancestors or descendants of a particular Ego.

• Collateral kin: are composed of Ego’s siblings and their descendants & the siblings lineal kin of ascending generations and their descendants as well.

What Are Descent Groups?• A descent group is any kin-ordered social group with

a membership in the direct line of descent from a real or fictional common ancestor. – Have a strong sense of identity.– Often share communally held property– Provide economic assistance to one another.– Engage in mutual civic & religious ceremonies.

Functions of Descent Groups

• Mechanism for inheriting property & political office.

• Provide aid and security to their members.

• Repositories of religious tradition, with group solidarity enhanced by worship of a common ancestor.

• Control behavior.

• Regulate marriages.

• Structure primary political units.

Unilineal Descent Groups• Unilineal systems: descent is traced through

parents and ancestors of only one sex (i.e mother’s line or father’s line, but not both).

• Matrilineal descent (uterine)– Descent traced exclusively through the female line

to establish group membership.

• Patrilineal descent (agnatic)– Descent traced exclusively through the male line

to establish group membership.• A woman’s children are not included in her patrilineal

group. http://www.umanitoba.ca/faculties/arts/anthropology/tutor/descent/unilineal/patri04.html

Matrilateral & Patrilateral Kin

Matrilateral kin (uterine): family members associated through Ego’s mother.

Patrilateral kin (agnatic): family members associated through Ego’s father.

• Most common unilineal descent group.

• A man, his children, his brother’s children, and his son’s children are all members of the same descent group.

• Females must marry outside their patrilineages and belongs to her father’s and his brother’s group.

• A woman’s children belong to the husband’s lineage rather than her own.

• Authority over the children lies with the father or his elder brother.

Matrilineal Descent• A woman, her siblings, her children,

her sister’s children, and her daughters children.

• Does not confer public authority on women, but women have more say in decision making than in patrilineal societies.

• 15% of the unilineal descent groups found among contemporary societies including:

– Native Americans (Hopi, Navajo, Cherokee & Iroquois).

– Truk & Trobrianders of the Pacific– Bemba, Ashanti, & Yao of Africa.

• If you are a member of a patrilineal descent group, your sisters belong to the same patrilineal descent group that you do.

Organizational Hierarchies of Lineages

• This diagram shows how lineages, clans, phratries, and moieties form an organizational hierarchy.

• Each moiety is subdivided into phratries, each phratry is subdivided into clans, and each clan is subdivided into lineages.

Types of Unilineal Descent Groups

• Moiety– Each group that results from a division of a

society into two halves on the basis of descent.

• Phratry– A unilineal descent group composed of two

or more clans that claim to be of common ancestry. If only two such groups exist, each is a moiety.

Types of Unilineal Descent Groups• Clan

– An extended unilineal kinship group, often consisting of several lineages, whose members claim common descent from a remote ancestor, usually legendary or mythological.

• Lineage– A unilineal kinship group

descended from a common ancestor or founder who lived four to six generations ago, and in which relationships among members can be stated genealogically.

In the highlands of Scotland clans have been important units of social organization.

Kinship Terminologies

• The Hawaiian system• The Eskimo system• The Iroquois system• Omaha system• Crow system• Sudanese or descriptive system

One of the founders of the anthropological relationship research was Lewis Henry Morgan.

The major patterns of kinship systems which Lewis Henry Morgan identified through kinship terminology in his 1871 work Systems of Consanguinity and Affinity of the Human Family are:

Eskimo System

• System of kinship terminology, also called lineal system, that emphasizes the nuclear family by specifically identifying the mother, father, brother, and sister, while lumping together all other relatives into broad categories such as uncle, aunt, and cousin.

Hawaiian System

• Kinship reckoning in which all relatives of the same sex and generation are referred to by the same term.

Polynesian societies throughout the Pacific Ocean are traditionally structured conforming to the Hawaiian system of kinship terminology.

Iroquois System• Kinship terminology wherein a father and father’s

brother are given a single term, as are a mother and mother’s sister, but a father’s sister and mother’s brother are given separate terms.

• • Parallel cousins are classified with brothers and sisters,

while cross cousins are classified separately, but (unlike Crow and Omaha kinship) not equated with relatives of some other generation.
