Unilineal
Unilineality is a system of determining descent groups in which one belongs to one's father's or mother's line, whereby one's descent is traced either exclusively through male ancestors (patriline), or exclusively through female ancestors (matriline). Both patrilineality and matrilineality are types of unilineal descent. The main types of the unilineal descent groups are lineages and clans. A lineage is a unilineal descent group that can demonstrate their common descent from a known apical ancestor. It is also called the simple unilineal descent.

Ambilineality
Ambilineality is a form of kinship affiliation of cognatic descent that relies on self-defined affiliation within a given social system, meaning individuals have the choice to be affiliated with their mother's or father's group. Common features of societies that practice ambilineality are a shared set of land, communal responsibilities, and collective ownership of some segments of wealth and debt in their societies. This system of descent is distinct from more common genealogical structures in that rather than determining affiliation and descent using the standard determinants of biological and genealogical relation, it instead relies heavily on voluntary affiliation with one's group, oftentimes being determined by factors including residence. Societies practicing ambilineal descent are especially common in Southeast Asia and the Pacific Islands. Polynesian cultures and Micronesian cultures are often ambilineal, including, for example, Samoans, Māori, Hawaiians and people of the ...

Lineage (anthropology)
A lineage is a unilineal descent group that can demonstrate their common descent from a known apical ancestor. Unilineal lineages can be matrilineal or patrilineal, depending on whether they are traced through mothers or fathers, respectively. Whether matrilineal or patrilineal descent is considered most significant differs from culture to culture. Matrilineal descent is associated with certain characteristics such as matriarchy, matrilocality and consanguinity Consanguinity ("blood relation", from Latin '' consanguinitas'') is the characteristic of having a kinship with another person (being descended from a common ancestor). Many jurisdictions have laws prohibiting people who are related by blood fr .... However a system can be matrilineal without possessing such characteristics.

Cultural Anthropology
Cultural anthropology is a branch of anthropology focused on the study of cultural variation among humans. It is in contrast to social anthropology, which perceives cultural variation as a subset of a posited anthropological constant. The portmanteau term sociocultural anthropology includes both cultural and social anthropology traditions. Anthropologists have pointed out that through culture people can adapt to their environment in non-genetic ways, so people living in different environments will often have different cultures. Much of anthropological theory has originated in an appreciation of and interest in the tension between the local (particular cultures) and the global (a universal human nature, or the web of connections between people in distinct places/circumstances). Cultural anthropology has a rich methodology, including participant observation (often called fieldwork because it requires the anthropologist spending an extended period of time at the research locat ...

Patrilineality
Patrilineality, also known as the male line, the spear side 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. This is sometimes distinguished from cognate kinship, through the mother's lineage, also called the spindle side or the distaff side. A patriline ("father line") is a person's father, and additional ancestors, as traced only through males. Traditionally and historically people would identify the person's ethnicity with the father's heritage and ignore the maternal ancestry in the ethnic factor. In the Bible In the Bible, family and tribal membership appears to be transmitted through the father. For example, a person is considered to be a priest or Levite, if his father is a priest or Levite, and the members of all the Twelve Tribes are called Israelites because ...

Matrilineality
Matrilineality is the tracing of kinship through the female line. It may also correlate with a social system in which each person is identified with their matriline – their mother's lineage – and which can involve the inheritance of property and/or titles. A matriline is a line of descent from a female ancestor to a descendant (of either sex) in which the individuals in all intervening generations are mothersin other words, a "mother line". In a matrilineal descent system, an individual is considered to belong to the same descent group as their mother. This ancient matrilineal descent pattern is in contrast to the currently more popular pattern of patrilineal descent from which a family name is usually derived. The ''matriline'' of historical nobility was also called their enatic or uterine ancestry, corresponding to the patrilineal or "agnatic" ancestry. Early human kinship In the late 19th century, almost all prehistorians and anthropologists believed, followi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clan
A clan is a group of people united by actual or perceived kinship and descent. Even if lineage details are unknown, clans may claim descent from founding member or apical ancestor. Clans, in indigenous societies, tend to be endogamous, meaning that their members can marry one another. Clans preceded more centralized forms of community organization and government, and exist in every country. Members may identify with a coat of arms or other symbol to show that they are an . Kinship-based groups may also have a symbolic ancestor, whereby the clan shares a "stipulated" common ancestor who serves as a symbol of the clan's unity. Etymology The English word "clan" is derived from old Irish meaning "children", "offspring", "progeny" or "descendants"; it is not from the word for "family" or "clan" in either Irish or Scottish Gaelic. According to the ''Oxford English Dictionary'', the word "clan" was introduced into English in around 1425, as a descriptive label for the organization ...

Most Recent Common Ancestor
In biology and genetic genealogy, the most recent common ancestor (MRCA), also known as the last common ancestor (LCA) or concestor, of a set of organisms is the most recent individual from which all the organisms of the set are descended. The term is also used in reference to the ancestry of groups of genes (haplotypes) rather than organisms. The MRCA of a set of individuals can sometimes be determined by referring to an established pedigree. However, in general, it is impossible to identify the exact MRCA of a large set of individuals, but an estimate of the time at which the MRCA lived can often be given. Such ''time to most recent common ancestor'' (''TMRCA'') estimates can be given based on DNA test results and established mutation rates as practiced in genetic genealogy, or by reference to a non-genetic, mathematical model or computer simulation. In organisms using sexual reproduction, the ''matrilineal MRCA'' and ''patrilineal MRCA'' are the MRCAs of a given population ...

Negative Relationship
In statistics, there is a negative relationship or inverse relationship between two variables if higher values of one variable tend to be associated with lower values of the other. A negative relationship between two variables usually implies that the correlation between them is negative, or — what is in some contexts equivalent — that the slope in a corresponding graph is negative. A negative correlation between variables is also called anticorrelation or inverse correlation. Negative correlation can be seen geometrically when two normalized random vectors are viewed as points on a sphere, and the correlation between them is the cosine of the arc of separation of the points on the sphere. When this arc is more than a quarter-circle (θ > π/2), then the cosine is negative. Diametrically opposed points represent a correlation of –1 = cos(π). Any two points not in the same hemisphere have negative correlation. An example would be a negative cross-sectional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
