In Social Anthropology and Sociobiology , polyandry ( Greek : ''poly'' many, ''andros'' man) means a female forming a stable sexual union with more than one male. The form of polyandry in which two (or more) brothers marry the same woman is known as fraternal polyandry, and it is believed by many Anthropologist s to be the most frequently encountered form. POLYANDRY IN NATURE In the field of behavioural ecology polyandry is a type of breeding adaptation in which one female mates with many males. Another similar breeding system to this is polygamy in which one male mates with many females (this is a ''very'' common system foundn in, eg, lions, deer, primates and many systems where there is an alpha male). A common example of this can be found in the Field Cricket ''Gryllus bimaculatus'' of the invetebrate order Orthoptera (containing crickets, grasshoppers and groundhoppers). The unusual thing about Polyandry in nature in general is that mating is costly: in other words, why mate with more than one male when you could be better spending your time foraging? Females in this species will mate with any male close to them, including siblings. Possible explanations for polyandry evolving in this species include: it is easier to ensure reproductive success females may be encouraging sperm competition between males, females may be getting food rewards from the males for allowing copulation to occur, and, for some as yet unknown reason, mating with multiple males increases the survival of the females offspring. Polyandry also occurs in some primates (eg, marmosets), other mammal groups (eg, the marsupial mouse species ''Antecchinus''), some bird species (in around 1% of all bird species, eg, superb fairy wrens) and insects (such as honeybees). DEFINITION In social anthropology, polyandry refers to a form of Polygamous Marriage (which simply means "multiple Spouse s."). Polyandry is the specific form of polygamy in which a woman is married to more than one Husband simultaneously. On the other hand Polygyny , is when a man has multiple Wives , which is by far the more common form of polygamy . OCCURRENCE Polyandry has occurred in Tibet (see Polyandry In Tibet ), Zanskar , Nepal , India ( Zanskar , Ladakh , Toda of South India , Nair s of Kerala , the Nymba and Pahari of North India ), and Sri Lanka . It is also encountered in some regions of China (especially Yunnan - the Mosuo People ), and in some Subsaharan African and American indigenous communities (notably the Surui of northwestern Brazil). In other societies, there are people who live in de facto polyandrous arrangements that are not recognized by the law. Polyandry in Primates and other Mammal s is usually correlated with reduced or reverse Sexual Dimorphism . When males of a species are much larger than females, Polygyny is usually practiced. As size difference decreases, or the females are larger than males, a species is more likely to practice Monogamy or Polyandry . The non-human Great Apes ( Gorilla s, Orangutan s, and Chimpanzee s) are highly dimorphic and practice Polygyny . Male and female Gibbon s (lesser apes) are similar in size and form monogamous pairs. Human males and females are less dimorphic in body size than other polygynous great apes, and are often Monogamous . Paternal Investment is often high in polyandrous Species . CONTROVERSY Polyandry is a controversial subject among anthropologists. For instance, Pennsylvania 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 ". On the other hand, in Tibet, which is the most well-documented cultural domain within which polyandry is practiced, the testimony of certain polyandrists themselves is that the marriage form is difficult to sustain. However, certain Monogamist s say the same thing about Monogamous Marriage . With particular regard to the supposed failure rate of polyandry, it is important to note that there are high rates of Infidelity and Divorce in "monogamous" societies, so that it is possible to argue that polyandry is not somehow uniquely unworkable. In Tibet polyandry has been outlawed, which means that it is difficult to measure the incidence of polyandry in what may have been the world's most "polyandrous" society. In other parts of the world, most traditional societies have been drastically altered or destroyed, so the incidence of polyandry in the past may not be accurately known. In India, among Tibetan refugee groups who fled the Chinese invasion of their country, polyandry is seldom encountered. CAUSES Some forms of polyandry appear to be associated with a) the perceived need to retain Aristocrat ic titles or Agricultural Land s within Kin groups, and/or b) with frequent male absence, for long periods, from the household. As to the former variety, consider that in Tibet where the practice is particularly popular among the wealthy Sakya priestly nobility as well as poor small Farmer s who could ill afford to divide their small holdings. As to the latter variety, as some males return to the household, others leave for a long time, so that there is usually one husband present. SOCIOBIOLOGY The term has been taken over into sociobiology, where it refers, analogously, to a Mating System in which one female forms more or less permanent bonds to more than one male. It can take two different forms. In one, typified by the Northern Jacana and some other ground-living birds, the female takes on much the same role as the male in a Polygynous species, holding a large territory within which several males build nests, laying eggs in all the nests, and playing little part in Parental Care . In the other form, typified by the Galápagos Hawk , a group of two or more males (which may or may not be related) and one female collectively care for a single nest. The latter situation more closely resembles typical human fraternal polyandry. These two forms reflect different resource situations: polyandry with shared parental care is more likely in very difficult environments, where the efforts of more than two parents are needed to give a reasonable chance of rearing young successfully. Honeybee s are said to be polyandrous because a queen typically mates with multiple males, even though mating is the only interaction that they have (the males go off and die, and the queen goes off and makes lots of babies, using stored sperm for those eggs that she fertilizes) POLYANDRY IN SOME NEW WORLD MONKEYS Some New World Monkey s, for example Callimicos have been observed living in polyandrous groups. Although groups may contain more than one female, the dominant female suppresses ovulation in subordinates, causing her to be the only one capable of reproduction. Callimico females regularly birth more than one offspring, and her eggs are separately fertilized by more than one male. Paternal investment is high in Callimicos, and males often carry infants on their backs, even when they are not the father. It has been suggested that multiple male mates were related, and therefore cooperation in caring for each other's young is adaptive, however, researchers tagged and tracked Callimicos over time, and noticed that unrelated males migrated to new groups to cooperate with non relatives as well as cooperating with relatives to care for young. It has also been suggested that females select cooperative males, and that the multiple offspring of Callimicos require paternal care for survival. Current research suggests that Polyandry is the dominant social structure in a subfamily of New World monkeys called Callitrichids , which include Tamarins , Marmosets , and other Monkeys . POLYANDRY IN RELIGION Islam bans polyandry completely. A woman may not have more than one husband. However, polygamy is allowed for men so that they can marry up to four wives. According to the very initial Surahs (chapters) of the Qur'an , like Surah Al-Muminoon and Surah Al-Ma`arij the Qur'an has specifically disallowed all sexual relationships, besides those, which are based on Nikah or those which were between a master and his slave girl {Link without Title} . The Qur'an says: ''And those who guard their chastity, except with their wives and their slave girls - for they are not to be blamed. But those who trespass beyond this {Link without Title} are the ones who are transgressors.'' (Al-Ma`arij 70: 29 - 31) It must be kept in mind that a Mut`ah relationship makes a woman neither a wife nor a slave girl of a person, whereas the Qur'an specifically restricts sexual relationships of a person with his wife and his slave girls only. It should also be noticed that the particular word used by the Qur'an in the referred verse, which is translated as "wives" is "azwaj" plural of "zaujah". In the Arabic language, a woman with whom a person enters into a contract of Mut`ah is called the "Mamtu`ah" of the person, she is not referred to as the "zaujah" (wife) of the person. The verse, therefore, is evidence to the fact that no other relationship besides the one based on Nikah was allowed by Islam. It may be clarified that slavery was not a part of the society that Islam developed. On the contrary, slavery was a part of the society which Islam inherited. Islam, from the very first day, tried to correct the situation in such a way that the institution was abolished, without a negative impact on the society. This was the reason why Islam tried to do away with the institution of slavery over a long period of time. Both Judaism and Christianity prohibit polyandry. There is at least one reference to polyandry in the Hindu epic, ''Mahabharata''. Draupadi, for whom the great war was fought, marries the five Pandava brothers. Surprisingly, this ancient text remains largely neutral to concept of polyandry; it is clearly tolerant to this main character practising it accepting it as a way of her life. Other, unmentioned religions's views on polyandry are various. REFERENCE Peter, Prince of Greece, ''A Study of Polyandry,'' The Hague, Mouton, 1963 www.understanding-islam.com SEE ALSO |
