Polyandry

Polyandry is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Polyandry rather than just read about it. In short: Polyandry (; from Ancient Greek πολύ (polú) 'many' and ἀνήρ (anḗr) 'man') is a form of polygamy in which a woman takes two or more husbands at the same time. Polyandry is contrasted with polygyny, involving one male and two or more females.

Key takeaways

  • Polyandry belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Polyandry to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Polyandry from memory before moving on to harder problems.

Reference excerpt

Polyandry (; from Ancient Greek πολύ (polú) 'many' and ἀνήρ (anḗr) 'man') is a form of polygamy in which a woman takes two or more husbands at the same time. Polyandry is contrasted with polygyny, involving one male and two or more females. If a marriage involves a plural number of "husbands and wives" participants of each gender, then it can be called polygamy, group or conjoint marriage. In its broadest use, polyandry refers to sexual relations with multiple males within or without marriage. Of the 1,231 societies listed in the 1980 Ethnographic Atlas, 186 were found to be monogamous, 453 had occasional polygyny, 588 had more frequent polygyny, and four had polyandry. Polyandry is less rare than this figure suggests, as it considered only those examples found in the Himalayan mountain region (eight societies). More recent studies have found at least four other societies practicing polyandry. Fraternal polyandry is practiced among Tibetans in Nepal and parts of China, in which two or more brothers are married to the same wife, with the wife having equal sexual access to them. It is associated with partible paternity, the cultural belief that a child can have more than one father. Several ethnic groups practicing polyandry in India identify their customs with their descent from Draupadi, a central character of the Mahabharata who was married to five brothers, although local practices may not be fraternal themselves. Polyandry is believed to be more likely in societies with scarce environmental resources. It is believed to limit human population growth and enhance child survival. It is a rare form of marriage that exists not only among peasant families but also among elite families. For example, polyandry in the Himalayan mountains is related to the scarcity of land. The marriage of all brothers in a family to the same wife allows family land to remain intact and undivided. If every brother married separately and had children, family land would be split into unsustainable small plots. In contrast, very poor persons not owning land were less likely to practice polyandry in Buddhist Ladakh and Zanskar. In Europe, the splitting up of land was prevented through the social practice of impartible inheritance. With most siblings disinherited, many of them became celibate monks and priests.

Types

Successional polyandry Unlike in fraternal polyandry (where a woman will receive a number of husbands simultaneously), in successional polyandry, a woman will acquire one husband after another in sequence. This form is flexible. These men may or may not be related. And it may or may not incorporate a hierarchical system, where one husband is considered primary and may be allotted certain rights or privileges not awarded to secondary husbands, such as biologically fathering a child. In cases where one husband has a primary role, the secondary husbands have the power to succeed the primary if he were to become severely ill or be away from the home for a long period of time or is otherwise rendered incapable of fulfilling his husbandly duties. Successional polyandry can likewise be egalitarian, where all husbands are equal in status and receive the same rights and privileges. In this system, each husband will have a wedding ceremony and share the paternity of whatever children she may bear.

Associated polyandry Another form of polyandry is a combination of polyandry and polygyny; whereas women are married to several men simultaneously and the same men may marry other women. It is found in some tribes of Africa such as villages in northern Nigeria and northern Cameroon. Usually, one of the woman's husbands will be chosen to be the husband of a woman from another tribe who would also have many husbands; this double-polyandrous union serves to form a marital alliance between tribes. Other Classifications: Equal polygamy, Polygynandry The system results in less land fragmentation, and a diversification of domestic activities.

Fraternal polyandry

Fraternal polyandry (from the Latin frater—brother), also called adelphic polyandry (from the Greek ἀδελφός—brother), is a form of polyandry in which a woman is married to two or more men who are brothers. Fraternal polyandry was (and sometimes still is) found in certain areas of Tibet, Nepal, and Northern India, as well as some central African cultures where polyandry was accepted as a social practice. The Toda people of southern India practiced fraternal polyandry, but monogamy has become prevalent recently. In contemporary Hindu society, polyandrous marriages in agrarian societies in the Malwa region of Punjab seem to occur to avoid division of farming land. Fraternal polyandry achieves a similar goal to that of primogeniture in 19th-century England. Primogeniture dictated that the eldest son inherited the family estate, while younger sons had to leave home and seek their own employment. Primogeniture maintained family estates intact over generations by permitting only one heir per generation. Fraternal polyandry also accomplishes this, but does so by keeping all the brothers together with just one wife so that there is only one set of heirs per generation. This strategy appears less successful the larger the fraternal sibling group is. Some forms of polyandry appear to be associated with a perceived need to retain aristocratic titles or agricultural lands within kin groups, and/or because of the frequent absence, for long periods, of a man from the household. In Tibet the practice was particularly popular among the priestly Sakya class. The female equivalent of fraternal polyandry is sororate marriage.

Partible paternity Anthropologist Stephen Beckerman points out that at least 20 tribal societies accept that a child could, and ideally should, have more than one father, referring to it as "partible paternity". This often results in the shared nurture of a child by multiple fathers in a form of polyandric relation to the mother, although this is not always the case. One of the most well known examples is that of Trobriand "virgin birth". The matrilineal Trobriand Islanders recognize the importance of sex in reproduction but do not believe the male makes a contribution to the constitution of the child, who therefore remains attached to their mother's lineage alone. The mother's non-resident husbands are not recognized as fathers, although the mother's co-resident brothers are, since they are part of the mother's lineage.

Worked examples

Example 1 — a first encounter with Polyandry

Start with the simplest possible case. Write down what Polyandry claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Polyandry before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Polyandry ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Polyandry

In research
Polyandry appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Polyandry in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Polyandry is common in secondary-school and first-year university syllabi. It links to neighbouring topics Heterosexuality, Mating systems, Polyandry, so understanding it makes those chapters shorter.
In everyday life
Look for Polyandry outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
