90-579: The Jino are one of the less numerous of the recognized minorities in China and the last one included as "national minority" because they were only recognized in 1979. A former name used for the Jino, Youle , means "following the maternal uncle," an indication of a matrilineal past. The Jino have a population of 20,900 people according to the census of the year 2000. Most of the Jino concentrate in Jinoshan, in

180-484: A "heavy dose" of their pre-existing beliefs including matrilineality. Tuareg women enjoy high status within their society, compared with their Arab counterparts and with other Berber tribes: Tuareg social status is transmitted through women, with residence often matrilocal . Most women could read and write, while most men were illiterate, concerning themselves mainly with herding livestock and other male activities. The livestock and other movable property were owned by

270-540: A different household. According to this source of further information about the Akan, "A man is strongly related to his mother's brother (wɔfa) but only weakly related to his father's brother. This must be viewed in the context of a polygamous society in which the mother/child bond is likely to be much stronger than the father/child bond. As a result, in inheritance, a man's nephew (sister's son) will have priority over his own son. Uncle-nephew relationships therefore assume

360-531: A different pattern, however: Example 1. Members of the (matrilineal) clan culture Minangkabau do not even have a surname or family name , see this culture's own section below. In contrast, members do have a clan name , which is important in their lives although not included in the member's name. Instead, one's name is just one's given name . Example 2. Members of the (matrilineal) clan culture Akan , see its own section below, also do not have matrilineal surnames and likewise their important clan name

450-442: A dominant position." Certain other aspects of the Akan culture are determined patrilineally rather than matrilineally. There are 12 patrilineal Ntoro (which means spirit) groups, and everyone belongs to their father's Ntoro group but not to his (matrilineal) family lineage and abusua . Each patrilineal Ntoro group has its own surnames, taboos, ritual purifications, and etiquette. A recent (2001) book provides this update on

540-480: A fitness reduction, increased territory defense, offspring guarding and an increased cost of growth. Benefits for helpers include a reduced chance of predation, increased foraging time, territory inheritance, increased environmental conditions and an inclusive fitness. For the breeding pair, costs include increased mate guarding and suppression of subordinate mating. Breeders receive benefits as reductions in offspring care and territory maintenance. Their primary benefit

630-446: A higher lifespan in their birth area. Among animals that are largely sedentary, breeding-site philopatry is common. It is advantageous to reuse a breeding site, as there may be territorial competition outside of the individual’s home range, and since the area evidently meets the requirements of breeding. Such advantages are compounded among species that invest heavily in the construction of a nest or associated courtship area. For example,

720-520: A mound for five to six months per year). In colonial seabirds, it has been shown that nest fidelity depends on multi-scale information, including the breeding success of the focal breeding pair, the average breeding success of the rest of the colony, and the interaction of these two scales. Breeding fidelity is also well documented among species that migrate or disperse after reaching maturity. Birds, in particular, that disperse as fledglings will take advantage of exceptional navigational skills to return to

810-427: A much higher rate of breeding-site philopatry in males than females among birds, and the opposite bias among mammals. Many possible explanations for this sex bias have been posited, with the earliest accepted hypothesis attributing the bias to intrasexual competition, and territory choice. The most widely accepted hypothesis is that proposed by Greenwood (1980). Among birds, males invest highly in protecting resources –

900-478: A particular ancestress. Several lineages are grouped into a political unit headed by a chief and a council of elders, each of whom is the elected head of a lineage – which itself may include multiple extended-family households. Public offices are thus vested in the lineage, as are land tenure and other lineage property. In other words, lineage property is inherited only by matrilineal kin. "The principles governing inheritance stress sex, generation and age – that

990-619: A particular area. The causes of philopatry are numerous, but natal philopatry , where animals return to their birthplace to breed, may be the most common. The term derives from the Greek roots philo , "liking, loving" and patra , "fatherland", although in recent years the term has been applied to more than just the animal's birthplace. Recent usage refers to animals returning to the same area to breed despite not being born there, and migratory species that demonstrate site fidelity: reusing stopovers, staging points, and wintering grounds. Some of

1080-459: A population. The exact causes for the evolution of natal philopatry are unknown. Two major hypotheses have been proposed. Shields (1982) suggested that philopatry was a way of ensuring inbreeding , in a hypothesis known as the optimal-inbreeding hypothesis. He argued that, since philopatry leads to the concentration of related individuals in their birth areas, and thus reduced genetic diversity, there must be some advantage to inbreeding – otherwise

1170-441: A previous site. Philopatric individuals exhibit learning behaviour, and do not return to a location in following years if a breeding attempt is unsuccessful. The evolutionary benefits of such learning are evident: individuals that risk searching for a better site will not have lower fitness than those that persist with a poor site. Philopatry is not homogenous within a species, with individuals far more likely to exhibit philopatry if

1260-535: A self-reinforcing process for a species. If the fitness benefits result in higher inclusive fitness of a family than the fitness of a non-cooperative family, the trait will eventually become fixed in the population. Over time, this may lead to the evolution of obligate cooperative breeding, as exhibited by the Australian mudnesters and Australo-Papuan babblers. Obligate cooperative breeding requires natally philopatric offspring to assist in raising offspring – breeding

They live in subtropical rainforest, home of elephants, wild oxen and monkeys. Among their cultural practices is tooth painting , in which soot made from pear trees is used. This table shows the population distribution of

1440-471: A social actuality of sexual equality." According to LeBow (based on Schlegel's work), in the Hopi, "gender roles ... are egalitarian .... [and] [n]either sex is inferior." LeBow concluded that Hopi women "participate fully in ... political decision-making." According to Schlegel, "the Hopi no longer live as they are described here" and "the attitude of female superiority is fading". Schlegel said

1530-469: A south Atlantic Island, where the species had never been previously recorded, demonstrate that range extension by roaming sub-adult birds is possible. Secondly, there may be sufficient gene exchange as to prevent divergence. For example, isolated (yet geographically close) populations of the Buller’s albatross ( T. bulleri bulleri ) have been shown to be genetically similar. This evidence has only recently, for

1620-427: A species could become fixed. Evidence for the optimal-inbreeding hypothesis is found in outbreeding depression . Outbreeding depression involves reduced fitness as a result of random mating, which occurs due to the breakdown of coadapted gene complexes by combining allele that do not cross well with those from a different subpopulation. However, it is important to note that outbreeding depression becomes more detrimental

1710-419: A species, there has also been found to be variation in rates of philopatry, with migratory populations exhibiting low levels of philopatry – further suggesting that the ecological cost of dispersal, rather than genetic benefits of either inbreeding or outbreeding, is the driver of natal philopatry. A number of other hypotheses exist. One such is that philopatry is a method, in migratory species, of ensuring that

1800-425: A study returned to exactly the same nest in consecutive years. Such site-specificity can lead to speciation, and has also been observed in the earliest stages of this process. The shy albatross ( Thalassarche [cauta] cauta ) was shown to have genetic differences in its microsatellites between three breeding colonies located off the coast of Tasmania. The differences are not currently sufficient to propose identifying

1890-512: A territory – against other males. Over consecutive seasons, a male that returns to the same territory has higher fitness than one that is not philopatric. Females are free to disperse, and assess males. Conversely, in mammals, the predominant mating system is one of matrilineal social organisation . Males generally invest little in the raising of offspring, and compete with each other for mates rather than resources. Thus, dispersing can result in reproductive enhancement, as greater access to females

1980-519: A version of male-preference matrilineal seniority , favoring brothers over sisters in the current generation (but allowing sisters to inherit if no brothers remained), but passing to the next generation through the eldest female line. In A Map of Virginia John Smith of Jamestown explains: His [ Chief Powhatan 's] kingdome descendeth not to his sonnes nor children: but first to his brethren, whereof he hath 3 namely Opitchapan, Opechancanough , and Catataugh; and after their decease to his sisters. First to

2070-461: Is a form, explains how individual offspring provide care for further offspring produced by their relatives. Animals that are philopatric to birthsites have increased association with family members, and, in situations where inclusive fitness is increased through cooperative breeding, may evolve such behaviour, as it will incur evolutionary benefits to families that do. Inclusive fitness is the sum of all direct and indirect fitness, where direct fitness

2160-423: Is a self-reinforcing process. Once genetic differences are sufficient, different species may be unable to interbreed to produce viable offspring. As a result, breeding could not occur anywhere except natal island, strengthening philopatry and ultimately leading to even greater genetic divergence. Philopatric species that do not migrate may evolve to breed cooperatively. Kin selection , of which cooperative breeding

2250-759: Is also matrilocal , a man will exercise guardianship rights not over the children he fathers but over his sisters' children, who are viewed as 'his own flesh'. These children's biological father – unlike an uncle who is their mother's brother and thus their caregiver – is in some sense a 'stranger' to them, even when affectionate and emotionally close. According to Steven Pinker , attributing to Kristen Hawkes, among foraging groups matrilocal societies are less likely to commit female infanticide than are patrilocal societies. Some 20 million Akan live in Africa, particularly in Ghana and Ivory Coast . (See as well their subgroups,

2340-482: Is an increased reproductive rate and survival. Cooperative breeding causes the reproductive success of all sexually mature adults to be skewed towards one mating pair. This means the reproductive fitness of the group is held within a select few breeding members and helpers have little to no reproductive fitness. With this system, breeders gain an increased reproductive, while helpers gain an increased inclusive fitness. Cooperative breeding, like speciation, can become

2430-449: Is available. On the other hand, the cost of dispersal to females is high, and thus they are philopatric. This hypothesis also applies to natal philopatry, but is primarily concerned with breeding-site fidelity. A more recent hypothesis builds on Greenwood’s findings, suggesting that parental influence may play a large role. Because birds lay eggs, adult females are at risk of being cuckolded by their daughters, and thus would drive them out. On

Cooperative breeding is a hierarchical social system characterized by a dominant breeding pair surrounded by subordinate helpers. The dominant breeding pair and their helpers experience costs and benefits from using this system. Costs for helpers include

The Tuareg (Arabic:طوارق, sometimes spelled Touareg in French, or Twareg in English) are a large Berber ethnic confederation found across several nations in north Africa, including Niger , Mali and Algeria . The Tuareg are clan -based, and are (still, in 2007) "largely matrilineal". The Tuareg are Muslim , but mixed with

2700-445: Is due to an innate behaviour in each individual, or to learning; however it has been shown that, in most species, older individuals show higher site fidelity. Neither of these hypotheses is as widely accepted as the optimal-inbreeding or dispersal hypotheses, but their existence indicates that the evolutionary causes of natal philopatry have still not been conclusively demonstrated. A major outcome of multi-generational natal philopatry

2790-461: Is genetic divergence and, ultimately, speciation . Without genetic exchange, geographically and reproductively isolated populations may undergo genetic drift . Such speciation is most evident on islands. For mobile island-breeding animals, finding a new breeding location may be beyond their means. In combination with a small population, as may occur due to recent colonisation, or simply restricted space, genetic drift can occur on shorter timescales than

2880-452: Is identified with their matriline, their mother's lineage , and which can involve the inheritance of property and titles. A matriline is a line of descent from a female ancestor to a descendant of either gender in which the individuals in all intervening generations are mothers. In a matrilineal descent system , an individual is considered to belong to the same descent group as their mother. This ancient matrilineal descent pattern

2970-462: 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. In the late 19th century, almost all prehistorians and anthropologists believed, following Lewis H. Morgan 's influential book Ancient Society , that early human kinship everywhere

3060-417: Is less common than among farmers. So for example, among the pygmies of Aka, which includes Biaka and Benzene, a young couple usually settles in her husband's camp after the birth of their first child. However, the husband can stay in the wife's community, where one of his brothers or sisters can join him. This can happen in societies where the bride's service is practiced, or in any other societies. According to

However, members' names do commonly include second names which are called surnames but which are not routinely passed down from either father or mother to all their children as a family name . Note well that if a culture did include one's clan name in one's name and routinely handed it down to all children in the descent group then it would automatically be

3240-815: Is observable in mainland species. The high levels of endemism on islands have been attributed to these factors. Substantial evidence for speciation due to natal philopatry has been gathered in studies of island-nesting albatross . Genetic difference is most often detected in microsatellites in mitochondrial DNA . Animals that spend much of their time at sea, but which return to land to breed exhibit high levels of natal philopatry and subsequent genetic drift between populations. Many species of albatross do not breed until 6–16 years of age. Between leaving their birth island, and their return, they fly hundreds of thousands of kilometres. High levels of natal philopatry have been demonstrated via mark-recapture data. For example, more than 99% of Laysan albatross ( Phoebastria immutabilis ) in

Biological anthropologists are now widely agreed that cooperative childcare was a development crucial in making possible the evolution of the unusually large human brain and characteristically human psychology. Although others refute the claims of supporters of

3510-435: Is the most common form of philopatry in females because it decreases competition for mating and increases the rate of reproduction and a higher survival rate for offspring. Natal philopatry also leads to a kin-structured population, which is when the population is more genetically related than less related between individuals in a species. This can also lead to inbreeding and a higher rate of natural and sexual selection within

3600-431: Is to say, men come before women and seniors before juniors." When a woman's brothers are available, a consideration of generational seniority stipulates that the line of brothers be exhausted before the right to inherit lineage property passes down to the next senior genealogical generation of sisters' sons. Finally, "it is when all possible male heirs have been exhausted that the females" may inherit. Each lineage controls

Philopatry is generally believed to help maintain the adaptation of a population to a very specific environment (i.e., if a set of genes has evolved in a specific area, individuals that fail to return to that area may do poorly elsewhere, so natural selection will favor those who exhibit fidelity). The level of philopatry varies within migratory families and species. The term

Most of the example cultures in this article are based on (matrilineal) clans . Any clan might possibly contain from one to several or many descent groups or family groups – i.e., any matrilineal clan might be descended from one or several or many unrelated female ancestors. Also, each such descent group might have its own family name or surname , as one possible cultural pattern. The following two example cultures each follow

4050-620: The Cegandum and Kagaw , whose historical account is enshrined in Serer religion, mythology and traditions . In Serer culture, inheritance is both matrilineal and patrilineal. It all depends on the asset being inherited – i.e. whether the asset is a paternal asset – requiring paternal inheritance ( kucarla ) or a maternal asset – requiring maternal inheritance ( den yaay or ƭeen yaay ).

In most species of animals, individuals will benefit from living in groups, because depending on the species, individuals are more vulnerable to predation and more likely to have difficulty finding resources and food. Therefore, living in groups increases a species' chances of survival, which correlates to finding resources and reproducing. Again, depending on

6750-483: The longer (temporally) that subpopulations have been separated, and that this does hypothesis does not provide an initial mechanism for the evolution of natal philopatry. A second hypothesis explains the evolution of natal philopatry as a method of reducing the high costs of dispersal among offspring. A review of records of natal philopatry among passerine birds found that migrant species showed significantly less site fidelity than sedentary birds. Among migratory species,

6840-473: The more familiar patrilineal surnames transmitted from father to son, the pattern most common among family names today. For clarity and for brevity, the scientific terms patrilineal surname and matrilineal surname are usually abbreviated as patriname and matriname . There appears to be some evidence for the presence of matrilineality in Pre-Islamic Arabia , in a very limited number of

6930-488: The other hand, young male mammals pose a threat to their dominant father, and so are driven to disperse while young. Natal philopatry commonly refers to the return to the area the animal was born in, or to animals remaining in their natal territory. It is a form of breeding-site philopatry. The debate over the evolutionary causes remains unsettled. The outcomes of natal philopatry may be speciation, and, in cases of non-dispersing animals, cooperative breeding. Natal philopatry

7020-439: The populations as distinct species; however divergence is likely to continue without outbreeding. Not all isolated populations will show evidence of genetic drift. Genetic homogeneity can be attributed to one of two explanations, both of which indicate that natal philopatry is not absolute within a species. Firstly, a lack of divergence may be due to founder effects , which explains how individuals that start new populations carry

7110-475: The power to remove leaders of whom they disapproved. Villages were established and relocated as the clans farmed new sections of the land when soil fertility lessened and when they moved among their fishing and hunting grounds by seasons. The area was claimed as a part of the Dutch New Netherland province dating from 1614, where active trading in furs took advantage of the natural pass west, but

7200-441: The process would have been evolutionary detrimental and would not be so prevalent. The major beneficial outcome under this hypothesis is the protection of a local gene complex that is finely adapted to the local environment. Another proposed benefit is the reduction of the cost of meiosis and recombination events. Under this hypothesis, non-philopatric individuals would be maladapted and over multi-generational time, philopatry within

7290-414: The same ancient ancestress. Marriage between members of the same abusua is forbidden. One inherits or is a lifelong member of the lineage, the political unit, and the abusua of one's mother, regardless of one's gender and/or marriage. Note that members and their spouses thus belong to different abusuas , mother and children living and working in one household and their husband/father living and working in

7380-426: The sexes interact in breeding areas, and that breeding actually occurs. A second is that philopatry provides a much higher chance of breeding success. Strict habitat requirements – whether due to a precisely adapted genome or not – mean that individuals that return to a site are more familiar with it, and may have more success in either defending it, or locating mates. This hypothesis does not justify whether philopatry

7470-530: The species, returning to their birthplace where that particular species occupies that territory is the more favorable option. The birthplaces for these animals serve as a territory for them to return for feeding and refuge, like fish from a coral reef . In an animal behavior study conducted by Paul Greenwood, overall female mammals are more likely to be philopatric, while male mammals are more likely to disperse. Male birds are more likely to be philopatric, while females are more likely to disperse. Philopatry will favor

7560-651: The spur to masculine superiority" and, within that, as that women were central to institutions of clan and household and predominated "within the economic and social systems (in contrast to male predominance within the political and ceremonial systems)", the Clan Mother , for example, being empowered to overturn land distribution by men if she felt it was unfair, since there was no "countervailing ... strongly centralized, male-centered political structure". The Iroquois Confederacy or League , combining five to six Native American Haudenosaunee nations or tribes before

7650-532: The traditional culture of the Guna people of Panama and Colombia, families are matrilinear and matrilocal, with the groom moving to become part of the bride's family. The groom also takes the last name of the bride. The Hopi (in what is now the Hopi Reservation in northeastern Arizona ), according to Alice Schlegel , had as its "gender ideology ... one of female superiority, and it operated within

7740-475: The universality of matrilocality or patrilocality , pointing out that hunter-gatherer societies have a flexible philopatry or practice multilocality, which in turn leads to a more egalitarian society, since both men and women have the right to choose with whom to live. According to some data, pastoralists and farmers strongly gravitate towards patrilocality, so patrilocality is a common phenomenon among non-Pygmies. But among some hunter-gatherers, patrilocality

7830-437: The vast majority of their lives, which is spent at sea. Small mutational changes in non-nuclear DNA that become fixed in small populations are likely to be the major driver of speciation. That there is minimal structural morphological difference between the genetically distinct populations is evidence for random genetic drift, rather than directional evolution due to natural selective pressure. Speciation through natal philopatry

7920-623: The women, whereas personal property is owned and inherited regardless of gender. In contrast to most other Muslim cultural groups, men wear veils but women do not. This custom is discussed in more detail in the Tuareg article's clothing section , which mentions it may be the protection needed against the blowing sand while traversing the Sahara desert . The Bororo people of Brazil and Bolivia live in matrilineal clans, with husbands moving to live with their wives' extended families. The clan system of

8010-590: Was matrilineal. This idea was taken up by Friedrich Engels in The Origin of the Family, Private Property and the State . The Morgan-Engels thesis that humanity's earliest domestic institution was not the family but the matrilineal clan soon became incorporated into communist orthodoxy . In reaction, most 20th century social anthropologists considered the theory of matrilineal priority untenable, although during

8100-744: Was – and, in the following list, still is if shown in italics  – inherited matrilineally. Examples include the Cherokee , Choctaw , Gitksan , Haida , Hopi , Iroquois , Lenape , Navajo and Tlingit of North America ; the Cabécar and Bribri of Costa Rica; the Naso and Kuna people of Panama; the Kogi , Wayuu and Carib of South America; the Minangkabau people of West Sumatra , Indonesia and Negeri Sembilan , Malaysia ;
