Lineage (anthropology) in the context of "Incest"

Genealogy (from Ancient Greek γενεαλογία (genealogía) 'the making of a pedigree') is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. The field of family history is broader than genealogy, and covers not just lineage but also family and community history and biography.

The record of genealogical work may be presented as a "genealogy", a "family history", or a "family tree". In the narrow sense, a "genealogy" or a "family tree" traces the descendants of one person, whereas a "family history" traces the ancestors of one person, but the terms are often used interchangeably. A family history may include additional biographical information, family traditions, and the like.

The term tribe is used in many different contexts to refer to a category of human social group. The predominant worldwide use of the term in English is in the discipline of anthropology. The definition is contested, in part due to conflicting theoretical understandings of social and kinship structures, and also reflecting the problematic application of this concept to extremely diverse human societies. Its concept is often contrasted by anthropologists with other social and kinship groups, being hierarchically larger than a lineage or clan, but smaller than a chiefdom, ethnicity, nation or state. These terms are similarly disputed. In some cases tribes have legal recognition and some degree of political autonomy from national or federal government, but this legalistic usage of the term may conflict with anthropological definitions.

In the United States (US), Native American tribes are legally considered to have "domestic dependent nation" status within the territorial United States, with a government-to-government relationship with the federal government.

In anthropology, kinship is the web of social relationships that form an important part of the lives of all humans in all societies, although its exact meanings even within this discipline are often debated. Anthropologist Robin Fox says that the study of kinship is the study of what humans do with these basic facts of life – mating, gestation, parenthood, socialization, siblingship etc. Human society is unique, he argues, in that we are "working with the same raw material as exists in the animal world, but [we] can conceptualize and categorize it to serve social ends." These social ends include the socialization of children and the formation of basic economic, political and religious groups.

Kinship can refer both to the patterns of social relationships themselves, or it can refer to the study of the patterns of social relationships in one or more human cultures (i.e. kinship studies). Over its history, anthropology has developed a number of related concepts and terms in the study of kinship, such as descent, descent group, lineage, affinity/affine, consanguinity/cognate and fictive kinship. Further, even within these two broad usages of the term, there are different theoretical approaches.

Bloodletting was the ritualized practice of self-cutting or piercing of an individual's body that served a number of ideological and cultural functions within ancient Mesoamerican societies, in particular the Maya. When performed by ruling elites, the act of bloodletting was crucial to the maintenance of sociocultural and political structure. Bound within the Mesoamerican belief systems, bloodletting was used as a tool to legitimize the ruling lineage's socio-political position and, when enacted, was important to the perceived well-being of a given society or settlement.

A totem (from Ojibwe: ᑑᑌᒼ or ᑑᑌᒻ 'doodem') is a spirit being, sacred object, or symbol that serves as an emblem of a group of people, such as a family, clan, lineage, or tribe, such as in the Anishinaabe clan system.

While the word totem itself is an anglicisation of the Ojibwe term (and both the word and beliefs associated with it are part of the Ojibwe language and culture), belief in tutelary spirits and deities is not limited to the Ojibwe people. Similar concepts, under differing names and with variations in beliefs and practices, may be found in a number of cultures worldwide. The term has also been adopted, and at times redefined, by anthropologists and philosophers of different cultures.

Casta (Spanish: [ˈkasta]) is a term which means "lineage" in Spanish and Portuguese and has historically been used as a racial and social identifier. In the context of the Spanish Empire in the Americas, the term also refers to a controversial 20th-century theoretical framework which postulated that colonial society operated under a hierarchical race-based "caste system". From the outset, colonial Spanish America resulted in widespread intermarriage: unions of Spaniards (españoles), indigenous people (indios), and Africans (negros).

Basic mixed-race categories that appeared in official colonial documentation were mestizo, generally offspring of a Spaniard and an Indigenous person; and mulatto, offspring of a Spaniard and an African. A plethora of terms were used for people with mixed Spanish, Indigenous, and African ancestry in 18th-century casta paintings, but they are not known to have been widely used officially or unofficially in the Spanish Empire.
