Exogamy
Exogamy is the social norm of marrying outside one's social group. The group defines the scope and extent of exogamy, and the rules and enforcement mechanisms that ensure its continuity. One form of exogamy is dual exogamy, in which two groups continually intermarry with each other. In social science, exogamy is viewed as a combination of two related aspects: biological and cultural. Biological exogamy is marriage of nonblood-related beings, regulated by forms of incest law. Cultural exogamy is marrying outside a specific cultural group; the opposite being endogamy, marriage within a social group. Biology of exogamy Exogamy often results in two individuals that are not closely genetically related marrying each other; that is, outbreeding as opposed to inbreeding. In moderation, this benefits the offspring as it reduces the risk of the offspring inheriting two copies of a defective gene. Increasing the genetic diversity of the offspring improves the chances of offspring reprod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Totemism
A totem (from oj, ᑑᑌᒼ, italics=no or '' 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. Contemporary neoshamanic, New Age, and mythopoetic men's movements not otherwise involved in the practice of a traditional, tribal religion have been known to use "totem" terminology for the personal identification with a tutelary spirit or spirit guide. However, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inbreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcros ...

Endogamy
Endogamy is the practice of marrying within a specific social group, religious denomination, caste, or ethnic group, rejecting those from others as unsuitable for marriage or other close personal relationships. Endogamy is common in many cultures and ethnic groups. Several religious and ethnic religious groups are traditionally more endogamous, although sometimes with the added dimension of requiring marital religious conversion. This permits an exogamous marriage, as the convert, by accepting the partner's religion, becomes accepted within the endogamous rules. Endogamy, as distinct from consanguinity, may result in transmission of genetic disorders, the so-called founder effect, within the relatively closed community. Adherence Endogamy can serve as a form of self-segregation; a community can use it to resist integrating and completely merging with surrounding populations. Minorities can use it to stay ethnically homogeneous over a long time as distinct communities within ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incest
Incest ( ) is human sexual activity between family members or close relatives. This typically includes sexual activity between people in consanguinity (blood relations), and sometimes those related by affinity (marriage or stepfamily), adoption, or lineage. It is strictly forbidden and considered immoral in most societies, and can lead to an increased risk of genetic disorders in children. The incest taboo is one of the most widespread of all cultural taboos, both in present and in past societies. Most modern societies have laws regarding incest or social restrictions on closely consanguineous marriages. In societies where it is illegal, consensual adult incest is seen by some as a victimless crime. Some cultures extend the incest taboo to relatives with no consanguinity such as milk-siblings, step-siblings, and adoptive siblings, albeit sometimes with less intensity. Third-degree relatives (such as half-aunt, half-nephew, first cousin) on average have 12.5% common geneti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tucano People
The Tucano people (sometimes spelt Tukano) are a group of Indigenous South Americans in the northwestern Amazon, along the Vaupés River and the surrounding area. They are mostly in Colombia, but some are in Brazil. They are usually described as being made up of many separate tribes, but that oversimplifies the social and linguistic structure of the region. Culture The Tucano are multilingual because men must marry outside their language group: no man may have a wife who speaks his language, which would be viewed as a kind of incest. Men choose women from various neighboring tribes who speak other languages. Furthermore, on marriage, women move into the men's households or longhouses. Consequently, in any village several languages are used: the language of the men; the various languages spoken by women who originate from different neighboring tribes; and a widespread regional 'trade' language. Children are born into the multilingual environment: the child's f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Surname
Chinese surnames are used by Han Chinese and Sinicized ethnic groups in China, Taiwan, Korea, Vietnam, and among overseas Chinese communities around the world such as Singapore and Malaysia. Written Chinese names begin with surnames, unlike the Western tradition in which surnames are written last. Around 2,000 Han Chinese surnames are currently in use, but the great proportion of Han Chinese people use only a relatively small number of these surnames; 19 surnames are used by around half of the Han Chinese people, while 100 surnames are used by around 87% of the population. A report in 2019 gives the most common Chinese surnames as Wang and Li, each shared by over 100 million people in China. The remaining top ten most common Chinese surnames are Zhang, Liu, Chen, Yang, Huang, Zhao, Wu and Zhou. Two distinct types of Chinese surnames existed in ancient China, namely ''xing'' () ancestral clan names and ''shi'' () branch lineage names. Later, the two terms began to be u ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8 ...

Francophone
French became an international language in the Middle Ages, when the power of the Kingdom of France made it the second international language, alongside Latin. This status continued to grow into the 18th century, by which time French was the language of European diplomacy and international relations. According to the 2022 report of the Organisation internationale de la Francophonie (OIF), 409 million people speak French. The OIF states that despite a decline in the number of learners of French in Europe, the overall number of speakers is rising, largely because of its presence in African countries: of the 212 million who use French daily, 54.7% are living in Africa. The OIF figures have been contested as being inflated due to the methodology used and its overly broad definition of the word francophone. According to the authors of a 2017 book on the world distribution of the French language, a credible estimate of the number of "francophones réels" (real francophones), tha ...

Aboriginal Australians
Aboriginal Australians are the various Indigenous peoples of the Australian mainland and many of its islands, such as Tasmania, Fraser Island, Hinchinbrook Island, the Tiwi Islands, and Groote Eylandt, but excluding the Torres Strait Islands. The term Indigenous Australians refers to Aboriginal Australians and Torres Strait Islanders collectively. It is generally used when both groups are included in the topic being addressed. Torres Strait Islanders are ethnically and culturally distinct, despite extensive cultural exchange with some of the Aboriginal groups. The Torres Strait Islands are mostly part of Queensland but have a separate governmental status. Aboriginal Australians comprise many distinct peoples who have developed across Australia for over 50,000 years. These peoples have a broadly shared, though complex, genetic history, but only in the last 200 years have they been defined and started to self-identify as a single group. Australian Aboriginal identity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazon River
The Amazon River (, ; es, Río Amazonas, pt, Rio Amazonas) in South America is the largest river by discharge volume of water in the world, and the disputed longest river system in the world in comparison to the Nile. The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon basin's most distant source, until a 2014 study found it to be the headwaters of the Mantaro River on the Cordillera Rumi Cruz in Peru. The Mantaro and Apurímac rivers join, and with other tributaries form the Ucayali River, which in turn meets the Marañón River upstream of Iquitos, Peru, forming what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro forming what Brazilians call the Amazon at the Meeting of Waters ( pt, Encontro das Águas) at Manaus, the largest city on the river. The Amazon River has an average discharge of about – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
