it finally clicked in my head while thinking about polygamy what the importance of family types — nuclear vs. extended, etc. — might be in the selection for altruistic behavioral traits, especially nepotistic altruism or clannishness. i should’ve thought through polygamy sooner instead of putting it off, but hey — procrastination is heritable, too, so in the words of h. solo, it’s not my fault! (~_^)

the logic of the mating patterns/inbreeding-outbreeding theory goes that, given the right set of circumstances (i.e. certain sorts of social environments), selection for nepotistic altruism/clannishness ought to go quicker or be amplified by inbreeding (close cousin marriage or uncle-niece marriage) simply because there will be more copies of any nepotistic altruism genes (alleles) that happen to arise floating around in kin groups. in other words, inbreeding should facilitate the selection for clannishness…if clannish behaviors are being selected for in a population.

the thing is, though: the individuals carrying certain versions (alleles) of nepotistic altruism genes need to direct their nepotistic behaviors towards other individuals carrying those same alleles, otherwise their actions will be for naught. (yeah. kin selection.) if they direct their nepotistic actions towards people who don’t share the same alleles, then the actions will be “wasted” and the behavioral traits won’t be selected for — or at least not very strongly — and they might fizzle out altogether.

let’s take an imaginary society as an example: say everyone in our pretend population always marries their first cousins. their father’s brother’s daughters (fbd) even, so that we get a lot of double-first cousin marriage. h*ck! let’s throw in some uncle-niece marriages on top of it all. the inbreeding coefficients in such a society would be very high, and if clannishness was being selected for in our highly inbred population, the selection ought to move pretty quickly.

but suppose we separated all the kids at birth from their biological families and set them out for adoption by unrelated individuals — people with whom they likely did not share the same nepotistic altruism alleles. think: the janissary system, only on a population-wide scale. if we did that, there should be virtually no selection for clannishness despite all the inbreeding since pretty much no one’s nepotistic behaviors would be directed towards other individuals with the same nepotistic altruism genes. in this case, kin selection would just not be happening.

such a society does not exist, and i don’t think ever has. but there are societies out there with certain family types — namely nuclear families (or even post-nuclear family societies!) — which ought to have a similar dampening effect on any selection for clannishness.

northwestern “core” europe has had very low cousin marriage rates since around the 800s-1000s, but it has also, thanks to manorialism, had nuclear families of one form or another (absolute or stem) since the early medieval period — nuclear families are recorded in some of the earliest manor property records in the first part of the ninth century from northeastern france [see mitterauer, pg. 59]. on the other hand, eastern europeans, like the russians and greeks, while they also seem to have avoided very close cousin marriage for several hundreds of years (which is not as long as northwestern europeans, but is quite a while), have tended to live in extended family groupings. you would think that nepotistic altruism could be selected for, or maintained more readily, in populations where extended family members lived together and interacted with one another on a more regular basis than in societies of nuclear family members where individuals interact more with non-kin. societies comprised of nuclear families are more like my hypothetical janissary society above where the altruism genes that might’ve been selected for via kin selection instead fade away in the wash.

we have to be careful, though, in identifying nuclear family societies. the irish of today, for instance, are typically said to be a nuclear family society, but the extended family does still interact A LOT (i can tell you that from first-hand experience). same holds true for the greeks and, i suspect, the southern italians. i would say that these populations have residential nuclear families, but not fully atomized nuclear families which have infrequent contact with extended family (think: the english). the early anglo-saxons in england were also characterized by residential nuclear families — the extended family (the kindred) was still very important in that society. the individuals in a residential nuclear family society probably do interact with non-family more than individuals in a society structured around extended families or clans, but less so than a true nuclear family society.

the thought for the day then?: family types can also affect the selection for clannishness/nepotistic altruism.

that is all! (^_^)

back to America 3.0 for a sec.

if i understand their argument correctly, bennett and lotus are proposing that the anglo-saxon absolute nuclear family — and the sort-of individual-based society that goes along with it — has distant roots stretching back to the pre-christian germans on the continent. they do say that there were obviously some changes to the anglo-saxon family type after the germanics arrived in (what would become) england — basically that the anglo-saxon nuclear family became even more nuclear over the course of the medieval period. but, by and large, they believe that there is a very long cultural continuity of family types and societal structures going all the way back to the early germans and that these cultural traditions are what made the anglo world pretty d*rn great.

based upon my readings over the last couple of years (feel free to flip through the “english” section in the “mating patterns in europe series” below ↓ in left-hand column), i think that bennett and lotus have got it pretty right. the anglo-saxon world IS exceptional (and, no, no one in my extended family can take ANY credit for that) — this exceptionalism has got to do with the structures of anglo-saxon society, very much so the fundamental family structures — and the development of these structures does go back to the pre-christian continental germans. HOWEVER, i think that bennett and lotus have missed some details — details which throw off the timing of their argument somewhat. for instance, as i pointed out in my last post on the book, they missed out entirely on the importance of the kindred in early germanic society, thus over-estimating the importance of the nuclear family at that point in time. early germanic society wasn’t composed of very tightly knit clans, but neither was it made up of truly independent nuclear families. the early germans were very much tied to their kindreds — including the anglo-saxons in early medieval england up to at least 1000 a.d. (see previous post).

whatever made the anglo-saxons finally give up on their extended families (the kindreds) happened after they got to england (although they may already have been primed for it). the kindred seems to be truly gone in england (at least in the south/southeast) by about 1200 a.d., the evidence suggesting that it was on its way out by at least ca. 1000 a.d. so, sometime between their arrival in the 400s-600s and 1200, something happened which resulted in the disappearance of the anglo-saxon kindred (and germanic kindreds on the continent, too, btw — but not all the germanic kindreds).

in this post, i want to nit-pick about another point that bennett and lotus made about the pre-christian germans on the continent [pg. 75]:

“They owned property individually, not communally, and not as families. Adult children and parents had separate and individual rights, not collective rights as a family.”

nope. as greying wanderer mentioned in the comments on the other post, this is incorrect.

here from “Jural Relations Among the Saxons Before and After Christianization” in The Continental Saxons from the Migration Period to the Tenth Century: An Ethnographic Perspective (2003) is giorgio ausenda on early saxon society on the continent. he’s drawing this information from the earliest written saxon laws. i’m quoting an extended bit here, since the first part includes an interesting description of how the early german kindred structure, including blood feuds, worked [pgs. 113-114]:

“There was no overarching structure with executive power in that society [pre-carolingian continental saxon society], even when stratified as in the case of the Saxons. There were no permanent ‘tribal chiefs’, but only heads of clans with little if any restraining power; the containment of violence was a private matter based on fear of retaliation between like corporate groups, i.e. ‘do not do onto others what you don’t want to be done to you’. The only restraining power the senior ‘elder’ of the group, which is also the etymological meaning of many terms for ‘chief’ all over the world, had was that of acting as an arbiter in an effort to reach consensus on compensations for murder or lesser injuries between contending parties belonging to different corporate groups under his jurisdiction; hence the Latin term *iudex* for such chiefs which were seen as acting mostly in legal palavers.

Property did not concern land, as this belonged to the corporate group as a whole and was the object of raids and counterraids to keep neighbouring groups away, or even wars rather than legal transfers. Tools and weapons were considered individual property and, in many cases … when the owners died, buried with them…. The only transmissible property was livestock and, in general, its apportionment was fixed by custom: women obtained their customary marriage endowment and men started owning livestock after they were wedded. They inherited their part in proportion to the number of sons of their deceased father, as sons were the only manual labor available in simple societies and were engaged in herding and minding their extended family’s herds and flocks.”

the early saxons, then, did NOT have property — not transferrable real estate anyway. (we saw something similar in early medieval ireland, although in that case, it was clearly the patrilineal clan that held common ownership of land.) in the case of the early saxons, land was held in common by — well, i’m not sure by whom (ausenda doesn’t say) — a set of related kindreds possibly? in any case, there is that group membership again — kindreds and wergeld in the case of murder/injury and now some sort of corporate group wrt land ownership. the continental saxons were not entirely independent, nuclear-family based individuals. they were a bit … clannish. clannish-lite.

whatever happened to make the anglo-saxons independent, property owning, absolute nuclear family individualists happened after they arrived on albion’s shores (but, i agree, their germanic background probably made a difference). and judging by what i’ve read (again, see the “mating patterns series” below), whatever happened doesn’t appear to have gained traction until about 1000 a.d. by 1200 it’s well underway, and by 1400 — well, i think you could probably drop a modern day englishman back into 1400s england, and he wouldn’t feel that disoriented. bennett and lotus are missing this timeline, because they are projecting too much anglo-saxonism too far back in time.

otherwise, they are very correct about the origins of anglo-saxon exceptionalism! (^_^)

(except for the fact that they believe it ALL to be about culture. that’s impossible, of course. at least in this universe. maybe in some alternate reality things are different. (~_^) )

edit: interesting. here is a quote from “The Kentish Laws” found in The Anglo-Saxons from the Migration Period to the Eighth Century: An Ethnographic Perspective (1997) regarding the beginnings of a shift from communal to private property (land) in kent in a law from the seventh century [pg. 217]:

“The Kentish laws portray a society where the change from movable to landed wealth was under way so much so that even the oldest laws contemplate fines for the breach of enclosures (Aebt. 27-9). It is clear here that land is no longer handled in tribal terms but as belonging to individuals.”

bonus content!: here are a couple of things i came across tonight re. the anglo-saxons and other early germanics that i found interesting, so i just thought i’d share….

1) in early medieval kent, arranged marriages were all the rage. from “The Kentish Laws” in The Anglo-Saxons from the Migration Period to the Eighth Century: An Ethnographic Perspective (1997) [pgs. 211, 216 – links added by me]:

“We have four English law-codes which all originated in the seventh century; the first three sets of laws were issued by the kings of Kent Æthelberht I, Hlothhere and Eadric, and Wihtred….

“The three laws contain a series of decrees about matrimony and have been made the object of considerable research into the (legal) position of women and its evolution…. This is one of the fields where the control of the kindred remained stable: the kinsmen arranged marriage and, after the wedding, continued to watch over the woman.

there’s the importance of the kindred again — in early medieval anglo-saxon (and jutish) england even.

interestingly, this is pretty much what happens in some parts the arab world today — arranged marriages, but the woman’s kin keeps an eye on her to make sure she’s ok. i just read recently, in fact, that in the hejaz, it’s very common for hejazi women to be set up with their own bank accounts by their family so that they have a set of financial resources independent from their husbands (but then they share a common household budget). who knew?

2) several readers have wondered out loud here — and so have i — why on EARTH did the northern europeans/the germanics (or any europeans for that matter) adopt christianity at all? why wouldn’t you just do what the frisians did when st. boniface or his ilk showed up and (presumably) tried to chop down the locals’ sacred trees — hang him from the nearest one?!

well, the saxons were forced to convert. by tptb (in this case the invading franks). huh. imagine that — so-called leaders forcing policies down the people’s throats. hard to imagine!

again from “Jural Relations Among the Saxons Before and After Christianization” [pg. 117 – links added by me]:

“The first ones [written saxon laws] were issued directly by or under the supervision of Frankish authorities. The first group, know as *Capitula de partibus Saxoniae*, issued in 777 at the end of centuries-long conflict with the Saxons, is none other than a martial law enforcing both public order and wholesale christianization. Of the total number of 31 articles, the first five list the penalties for crimes against churches and priests; the next four establish stiff penalties for acts of ‘paganism’ including the death penalty for whomever should refuse to be baptized. Among them a lone ray of light: law number 6 which prohibits witchcraft accusations *’secundum more paganorum’*…. Law 14 is for repentants who, having committed a crime, might confess to a priest, hence would be exempt from the death penalty *’testimonio sacerdote’*.

“The next group of laws from 15 to 19 lays down the duties towards the Church, consisting of a certain number of inhabitants in each hamlet donating to the church *’servum et ancillam’*, and that the tenth part *’decimam’* of the value of penalties incurred, or of one’s subsistence labour must be given to the church. The remaining articles list the prohibitions and duties following on religious festivities and ceremonies.

“This brief set of laws ends with … a final prohibition of unauthorized assemblies….”

so there!

previously: the anglo-saxons and america 3.0

(note: comments do not require an email. birds with mustaches!)

been reading America 3.0 written by two of the chicago boyz (hey chicago boyz! *waves*). i got interested in the book after reading daniel hannan’s review of it in the telegraph a couple of weeks ago in which he said:

“Their conclusion? That English, later Anglosphere, exceptionalism, is very real. That the rise of our language and culture to their current unprecedented dominance – what one commentator terms ‘Anglobalisation’ – is based on a series of properties that are either unique to the English-speaking peoples, or shared only with a handful of kindred cultures in northwestern Europe. Among these properties are the common law, representative government, Protestantism, dispersed landownership, civil associations separate from the state and – of particular interest to these authors – the unusual nature of the family.

They show that the Anglosphere dispenses with the extended family structures which, in most places, have legal as well as cultural force. In many societies, the peasant family has traditionally been treated as a kind of collective landowner, within which there are reciprocal responsibilities. Children, even in adulthood, have been expected to work on the family plot, receiving board and lodging. Marriages are typically arranged, and daughters-in-law come under the authority of the head of their new household. Even when the law recognises individual autonomy, custom is often slow to follow.

“The Anglosphere scarcely resembles the Eurasian landmass in its family structures. Our notion of the family is limited and nuclear. Most English-speakers in most centuries wanted to set up home on their own, independently, with just their spouse and children – although economic circumstances did not always allow that aspiration to be fulfilled.

The notion that the limited family underpins Anglosphere exceptionalism – which draws heavily on the work of the French anthropologist and demographer Emmanuel Todd – is intriguing. I see the cultural difference all around me in the European Parliament. In most Continental states, your social life is largely taken up with your extended family: you have an endless stream of weddings and christenings to go to, sometimes of very distant cousins. Britons and Americans, by contrast, expect to leave their parental home in their teens, either to go to university or to work. We make friends away from home, and they become the core of our social life. Indeed, the word ‘friend’ carries more force in English than in many European languages, in which it is bestowed quickly and generously, but often means little more than what we mean by a Facebook friend. When a Spaniard says of someone ‘es muy amigo mío’, he simply means that he gets on with the chap.”

oh, emmanuel todd! i love emmanuel todd!

i disagree with lotus and bennett on two major points.

firstly, that the u.s. is on the verge of an economic/societal upturn that will be even bigger and better than those of the past (thus the title of the book). meh. maybe. i’m not so hopeful as they are, but that’s probably just because i’m a pessimist. i’ll be very happy to be proven wrong!

my other disagreement with the authors is more of an irreconcilable difference [pgs. 25-26, 60-61]:

“What we have found in our research is that our distinctive and exceptional American culture has extremely deep roots, stretching back over a thousand years, long before our own national Founding and our Constitution, long before the the first English settlements in North America….”

yes, definitely. i’d agree with that. but…

“The word ‘culture’ may seem amorphous, something you would know by intuition but cannot necessarily pin down. Even professional anthropologists, whose job it is to study and understand culture, seem to have trouble pinning down exactly what they mean by it. For our purposes, we define culture as the distinctive patterns of behavior within a specified group of people that are transmitted from one generation to the next and are not genetic in origin.

It is very important to understand that culture is not genetic. Adopted children and immigrants may come from entirely different genetic backgrounds, but they adopt artifacts of culture such as language, values, and customs as readily as do biological children of parents within that culture. It is indisputable that the culture we describe in this book can be and has been adopted by people of every possible ethnic background….”

well, no … not exactly.

“[T]he strictly racial explanation for the Germanic roots of English liberty is simply and demonstrably incorrect. We now know more about human biology and genetics than did the writers of the eighteenth and nineteenth centuries. We know for a fact that there is no genetic basis for the English way of life. There is nothing special in the DNA of any English ‘race’ that especially suits them for liberty….

“The historical record as it now stands, based on documents, archeology, and genetic evidence, shows that *the foundations of English liberty were not genetic or racial, but cultural, institutional, legal, and political*.”

oh, no, no, no, no, no!

i’m actually not interested in debating this in this post, but, in response to these passages, i will just ask my one, favorite, hopefully irritating question: where does culture come from?

i do want to nitpick a small-ish point with lotus and bennett, though. their main argument is that the anglo-saxon absolute nuclear family goes way, waaaay back — pretty much to, or nearly to, the time of the settlement of the anglo-saxons in england — and, thanks to that, both england and america have been characterized by all sorts of neat things like: individualism, a love of liberty, nonegalitarianism, competitiveness, an enterprising spirit, mobility, voluntarism, middle-class values, an instrumental view of government, and suburbia (a spacious home and backyard for each and every nuclear family).

i generally agree with that assessment, although, as you know, i’d throw mating patterns into the mix there — especially that the mating patterns of the angles and saxons and other germanic tribes probably affected their family types, the general pattern being: the closer the mating types, the larger the families (think: the arabs with their father’s brother’s daughter marriage and their huge clans/tribes), while the more distant the mating types, the smaller the families (think: well, think the english with their avoidance of close cousin marriage for ca. 1000-1200 years and their absolute nuclear families). and, of course, i’d toss evolution and genetic differences between populations in there, too.

lotus and bennett, amongst other points, say of the saxons that settled in england that [pg. 75]:

“- They were free people. They were independent minded, individually and in their tribal organization….
– They owned property individually, not communally, and not as families. Adult children and parents had separate and individual rights, not collective rights as a family.
– They traced their lineages through both the male and female line. This prevented clans or extended families from forming and becoming exclusive, as happens when lineage is traced solely through the male line. As a result extended families or clans did not have collective legal rights, or any recognized political role.”

yes. but this is a slight oversimplification of the situation. no, the pre-christian germanics didn’t have strong clans, but they did have kindreds which were, in fact, very important in many cases when legal issues arose, in particular in the instance of wergeld payment and collection, i.e. compensation for when a member of a kindred was injured or killed. the members of a person’s kindred in germanic society — and this includes anglo-saxon society in early medieval england — were obliged to undertake a feud if wergeld payments were not met — by the guilty party’s kindred. in other words, two whole kindreds were involved whenever someone was injured or killed by another person.

this was a sort of clannishness-lite, then — actual clans did not exist in pre-christian germanic society, but kindreds did. and these extended families were very important in early anglo-saxon society, even though people may have regularly resided in nuclear family units. according to lorraine lancaster, this didn’t change until after ca. 1000 a.d., four- to six-hundred years after the anglo-saxons arrived in england, when wergeld began to be paid/collected by a person’s friends or fellow guild members rather than extended family members [pgs. 373, 375 – see also this post]:

“Phillpotts has effectively demonstrated the weakness of Anglo-Saxon kin groups compared with certain related systems on the continent….

“During the period they [‘friends’] gained continued importance as oath-helpers. After the end of the tenth century, it was even permissible for a feud to be prosecuted or wergild claimed by a man’s associates or guild-brothers. If murder was done *within* the guild, kinsmen again played a part….”

so, yes, the importance of the nuclear family does have its roots in germanic and anglo-saxon society, but the extended family in the form of the bilateral kindred was also a very significant element of germanic societies — until quite late in some regions of europe. the importance of the germanic kindred waned over the course of the early medieval period, very much so in england, i think thanks to The Outbreeding Project undertaken by northwest europeans beginning in the early medieval period. (see mating patterns in europe series below ↓ in left-hand column.)

(note: comments do not require an email. coooookieeee!)

i’ve mentioned this before (see here and here and here), specifically wrt family types like nuclear families vs. clans, but i thought i’d bring it up again:

more attention ought to be paid to things like mating patterns, family types, and the social structures within societies as creating different sorts of selection pressures for different types of individuals — personality types, iq, other behavioral patterns, etc.

some researchers have been looking at how, for instance, mating patterns can affect genes and genomes in populations: cochran and harpending have been investigating paternal age and mutation rates, some of greg’s low-hanging fruit (double entendre NOT intended), and hage and marck discovered how matrilineality and matrilocal residence affected the distribution of y-chromosome haplogroups in polynesia (other researchers have done similar research for other parts of the world) — and these types of research are really interesting and very exciting, but they’re not quite what i’m talking about.

here’s one example of the sort of thing i’m interested in asking (and answering!): what sort of persons succeed in reproducing the most in a society based on the nuclear family versus a society based around extended families or even clans? what sort(s) of personalities do they have? how high of an iq do they need? what other types of behavioral patterns do they exhibit?

gregory clark famously found that, over the course of the medieval period in england, it was the hard-working, thrifty, forward planning folks with middle-class values who reproduced the most. but he made next to no (actually i think it was none whatsoever) mention of the prevailing family type in medieval england: the nuclear family, which was well-established by at least the 1200s.

imagine what sort of people would do well — what sorts of traits would be selected for — in a society which was based on the individual and his nuclear family making it on their own — with a little help from immediate family and, most importantly, friends and neighbors. someone trustworthy? and trusting? someone who can plan ahead, because those who don’t can’t rely on falling back on an extended family/clan? someone with not the lowest iq in the world?

and what sorts of people do well in a clannish society? those who believe in putting family first ahead of friends and/or the wider community? those who trust their family members more than outsiders, because the outsiders have always had their own family members that they prioritized? individuals who don’t feel a strong urge to plan that far in advance, ’cause hey — uncle joe or cousin ahmed will be there to help out when times are tough? too many individuals who are not so bright because their brighter relatives support them and their offspring?

here, once again, is my favorite example of how at least some clannish societies work. (see if you can spot the potential dysgenic practices!) this is from modern-day egypt — upstream which is much more clannish/tribal than the delta region of the country — Development and Social Change in Rural Egypt (1986), pgs. 150-51:

“The importance that poor peasants attach to the brokerage services by a single wealthy patron can be seen in the continuing importance of the extended family unit in rural Egypt. In the village of El-Diblah [pseudonymous village representative of upper egypt], as well as other Egyptian communities, politics and much of life itself are organized on the basis of large, extended families numbering 500 members or more. These extended families are broad patrilineal structures, which may or may not be able to trace themselves back to a single historical founder. While these extended families do not represent monolithic social structures, most fellahin are animated by a real feeling of belonging to a particular extended family unit. When they need a loan or help with outside government officials, poor peasants will often turn to the leader or a prominent person within their extended family. In the village of El-Diblah three of the four leading extended families are headed by rich peasants. In the eyes of most fellahin, this is exactly as it should be. In the countryside wealth acquired by virtually any means provides a good indication of an individual’s ability to deal with (or against) the ouside world.

“‘Zaghlul,’ for example, is the rich peasant head of one of the leading extended families in El-Diblah. A short, wiry 55-year-old fellah, whose dress and mannerisms are almost indistinguishable from those of other peasants in the village, Zaghlul now owns about 25 feddans of land. Much of this land is planted in sugar cane, a crop that he uses to supply his own cane press that produces black molasses for local sale. As the owner of 25 feddans of land, and the proprietor of one of the few ‘manufacturing’ enterprises in the village, Zaghlul is able to dispense a wide number of agricultural and non-agricultrual work opportunities to favored members of his extended family. Many of the poorer members of his extended family live in a mud-brick settlement surrounding Zaghlul’s modern two-story, red-brick house. In the evenings a steady stream of these poor people come to Zaghlul’s house, seeking brokerage and intercessionary services (for example, help in securing agricultural inputs and medical services from the government)….

mating patterns matter. family types matter. social structures matter. all in the sense that they (i think) set up selection pressures for different sorts of traits — or at least they can do. no doubt they cannot be looked at in isolation (one needs to consider all sorts of other life factors, too, like economic structures), but i think they’re probably pretty important — and need more attention. from this perspective, i mean.

(note: comments do not require an email. low-hanging fruit.)

in “Family Structure, Institutions, and Growth: The Origins and Implications of Western Corporations,” stanford economist avner greif wrote [pgs. 308-09]:

“There is a vast amount of literature that considers the importance of the family as an institution. Little attention, however, has been given to the impact of the family structure and its dynamics on institutions. This limits our ability to understand distinct institutional developments — and hence growth — in the past and present. This paper supports this argument by highlighting the importance of the European family structure in one of the most fundamental institutional changes in history and reflects on its growth-related implications.

“What constituted this change was the emergence of the economic and political corporations in late medieval Europe. Corporations are defined as consistent with their historical meaning: intentionally created, voluntary, interest-based, and self-governed permanent associations. Guilds, fraternities, universities, communes, and city-states are some of the corporations that have historically dominated Europe; businesses and professional associations, business corporations, universities, consumer groups, counties, republics, and democracies are examples of corporations in modern societies….

“In tracing the origins of the European corporations, we focus on their complementarity with the nuclear family. We present the reasons for the decline of kinship groups in medieval Europe and why the resulting nuclear family structure, along with other factors, led to corporations. European economic growth in the late medieval period was based on an unprecedented institutional complex of corporations and nuclear families, which, interestingly, still characterizes the West. More generally, European history suggests that this complex was conducive to long-term growth, although we know little about why this was the case or why it is difficult to transplant this complex to other societies….

“The conquest of the Western Roman Empire by Germanic tribes during the medieval period probably strengthened the importance of kinship groups in Europe. Yet the actions of the church caused the nuclear family — consisting of a husband and wife, children, and sometimes a handful of close relatives — to dominate Europe by the late medieval period.

The medieval church instituted marriage laws and practices that undermined kinship groups…. The church … restricted marriages among individuals of the same blood (consanguineous marriages), which had historically provided one means of creating and maintaining kinship groups….

“European family structures did not evolve monotonically toward the nuclear family, nor was their evolution geographically or socially uniform (Greif, 2006, chap. 8).** By the late medieval period, however, the nuclear family was dominant. Even among the Germanic tribes, by the eighth century the term ‘family’ denoted one’s immediate family and, shortly afterwards, tribes were no longer institutionally relevant. Thirteenth-century English court rolls reflect that even cousins were as likely to be in the presence of nonkin as with each other. The practices the church advocated (e.g., monogamy) are still the norm in Europe. Consanguineous marriages in contemporary Europe account for less than 1 percent of the total number of marriages, in contrast to Muslim and Middle Eastern countries where such marriages account for between 20 and 50 percent per country (Alan H. Bittles, 1994). Among the anthropologically defined 356 contemporary societies of Euro-Asia and Africa, there is a large and significant negative correlation between the spread of Christianity (for at least 500 years) and the absence of clans and lineages; the level of commercialization, class stratification, and state formation are insignificantly correlated (Andrey V. Korotayev, 2003).”

the presence (or absence) of clans in societies is somehow connected to the mating patterns of societies. in fact, it seems to be that a whole range of kinship-based societal types is somehow connected to a whole range of mating patterns: the “closer” the mating patterns in a society, the more “clannish” it tends to be — the more distant the mating patterns, the less “clannish.”

so we see a spectrum of “clannish” societies ranging from the very individualistic western societies characterized by nuclear families and, crucially, very little inbreeding (cousin marriage, for instance) to very tribal arab or bedouin societies characterized by nested networks of extended families and clans and large tribal organizations and having very high levels of inbreeding (specifically a form of very close cousin marriage which increases the degree of inbreeding). falling somewhere in between these two extremes are groups like the chinese whose society is built mostly around the extended familiy but in some regions of china also clans — or the medieval scots (especially the highland scots) whose society for centuries was built around the clan (h*ck, they even coined the term!). these “in-betweener” groups are, or were, characterized by mid-levels of inbreeding (typically avoiding the very close cousin marriage form of the arabs).

furthermore, not only do the degrees of extended family-ness/clannish-ness/tribal-ness in societies seem to be connected to the degrees of inbreeding in those societies, the degrees of “clannism” also seem to be connected to the degree of inbreeding — the more inbreeding, the less civicness, the less democracy, the more corruption, and so on.

it’s not clear what exactly the mechanism(s) behind this inbreeding-leads-to-clannishness pattern is, but since mating patterns are involved, and mating is a very biological process, it seems likely (to me anyway) that the explanation is something biological — i.e. some sort or sorts of evolutionary process/es — like natural selection — resulting in different/different degrees of behavioral traits related to “clannism” in different populations with inbreeding acting as a sort of accelerant for those processes.

clans and clannism, then, are not things that peoples “fall back on” in the absence of a state as mark weiner suggests in The Rule of the Clan [kindle locations 106-108]:

“[I]n the absence of the state, or when states are weak, the individual becomes engulfed within the collective groups on which people must rely to advance their goals and vindicate their interests. Without the authority of the state, a host of discrete communal associations rush to fill the vacuum of power. And for most of human history, the primary such group has been the extended family, the clan.”

rather, people’s attachments to their extended families/clans/tribes — and, more importantly, their tendencies towards clannish behaviors — are likely innate behaviors. and those behaviors likely vary, on average, between populations since (long-term) mating patterns have varied — and, indeed, still vary — between populations.

such innate behaviors cannot be changed overnight — certainly not within a generation or even two (evolution does take some amount of time — but not, necessarily, extremely long amounts of time either) — and definitely not by simply changing a few laws here and there in the hopes of encouraging individualism. as avner greif grasped, although probably not fully because he’s likely missed the underlying biology of what he’s noticed, family structures need to be altered in order to effect changes to larger societal structures (again, all via tweaks to innate behavioral tendencies). and, again, that can’t be done overnight — as greif pointed out, the process in europe began in the early medieval period (with the church’s bans on cousin marriages) and didn’t really start to take hold until the late medieval period — i.e. a 500 year (or, conservatively, a ca. 25 generation) timeline.

from sam worby’s Law and Kinship in Thirteenth-Century England [pgs. 1-2 – link and emphases added by me]:

Charles Donahue Jr’s magisterial comparative study of marriage in England, France and Belgium has confirmed a remarkable pattern of family interaction for England. His thorough and statistical analysis of the surviving records of cases before the archbishop of York’s consistory court in the fourteenth and fifteenth centuries, and Ely consistory court between 1374 and 1381, incidentally seems to confirm that there was no clan or corporate kinship system operating in the areas covered, and, by inference, in England more widely (given the consistency of results between the two evidence sets). There was, he shows, even relatively low levels of parental involvement in marriage choice. Given the importance of marriage as a social institution and the potential consequences flowing from choice of partner — in property, alliance and social standing for example — it seems remarkable that an average of only 37 per cent of York cases showed evidence of parental involvement. While there was evidence for arranged marriages in the records of both courts, many couples appear to have acted independently. Whether this is qualified as ‘astonishingly’ or ‘unusually’ individualistic, the fact remains that many couples operated with relative freedom within the scope of the canon law marriage rules.

This individualistic pattern confirms a picture of family interaction for England found elsewhere, through evidence of marriage patterns, but also more broadly. From the Anglo-Norman nobility to later medieval peasants, the picture is of a limited family (although this book will not in fact focus on peasant kinship, but rather on kinship insofar as it was a general structure, transcending class and status). The extended kindred did not live together; the typical co-resident family appears to have been nuclear. There is evidence of kin interaction, particularly suggestive of closeness between siblings. There is a broad consensus about the narrowness of the operative kin group in England. It was rarely much larger than the immediate family, mostly the co-resident nuclear family, with some obligations and traceable contact extending out to cousins, and some closeness to siblings and occasionally to uncles and aunts. This pattern is unusual in comparison to other areas of Europe. It is suggestive to note that Franco-Belgian courts showed evidence for a higher level of family involvement in marriage arrangements. It is also striking to contrast the pattern of relatively informal clans able to act together in some European countries, such as Italy.

(note: comments do not require an email. hi there!)

in the interests of k.i.s.s. k.i.s.s., i decided to look again at mating patterns and family types in the murdock ethnographic atlas, but this time looking just at exogamous, agamous and endogamous mating practices without all the cousin-marriage business.

so, what i looked at this time were just what sorts of “domestic organizations” (nuclear/stem, polyandrous/polygynous, extended families) go with different “community marriage organizations” (exogamous, agamous, endogamous). (see previous post for explanations of all those categories.)

i got results for 184 societies. as in the previous post, i collapsed nuclear & stem families, small & large extended families, and the various exogamous & endogamous categories together. this time i left in the polygynous/polygamous family types and the agamous mating patterns. here’s what i found (click on chart for LARGER view):

again, nuclear and stem families just do not go together with endogamous mating patterns. you need exogamous or agamous (not caring one way or the other) mating patterns to get nuclear or stem families. there is clearly a relationship between endogamy and extended families.

also, there seems to be more endogamy in the world than exogamy. and quite a lot of peoples who don’t seem to be able to make up their minds on the issue.

for the record, the two murdock atlas societies that are endogamous AND have nuclear or stem families (there’s one of each) are:

– the ahaggaren tuareg tribe (endogamous marriage patterns with nuclear families)
– the konso people of ethiopia (endogamous marriage patterns with stem families, occasionally polygyny).

(note: comments do not require an email. sifaka alert!)

i keep saying that consanguineous/endogamous mating patterns lead to clannishness/tribalism, but do they really? i think the evidence strongly suggests yes (see the mating patterns series in the left-hand column below ↓), but it would be nice to quantify it. but how?‘s data on modern cousin marriage rates would be easy and convenient to use, but where are the data on whether those societies are individualistic, clannish or tribal or whatever? i’m not aware of anything like that (if anyone is, please let me know!). i could, perhaps, sit down and, based on what i know, rate all these nations as clannish, etc., but 1) i might be wrong in some or a lot of the cases, and 2) i’d be worried about introducing my own biases. so that’s no good.

so, i thought i’d try george murdock‘s ethnographic atlas to see if i could find any useful info there. i did! (i think.)

what i looked for: which types and what frequencies of different basic family types (domestic organization) are found in societies with various mating patterns (number of cousin marriage [preferential] and community marriage organization). i got results for 186 different societies.

“domestic organization” equals:

– independent nuclear monogamous
– independent nuclear occasional polygyny
– independent polyandrous families
– polygynous unusual cowives pattern
– polygynous usual cowives pattern
– stem families
– small extended families
– large extended families

i collapsed these categories into: nuclear/stem families, polygynous/polyandrous families and extended families. i figured stem families are practically nuclear families, just with grandma and/or grandpa included. i left the polygynous/polyandrous societies (there were 30 of them) out of the final analysis ’cause i just don’t know what they are. nuclear families? extended families? i dunno.

“number of cousin marriage [preferential]” equals:

– two of four cousins (e.g. paternal)
– one of four cousins (e.g. fbd)
– no first cousins
– first and some second cousins excluded
– no preferential or prescriptive unions

the first four categories are all versions cousin marriage, so i collapsed those together.

for each of the societies that came back as “no preferential or prescriptive unions” (a total of 123), i drilled down into the “community marriage organization” category to see if i could work out if their marriage patterns were generally endogamous or exogamous.

“community marriage organization” equals [for more on what these categories mean, see pg. 7 here – opens pdf]:

– demes (not segmented into clan barrios) [exogamous]
– segmented communities without local exogamy [endogamous]
– agamous communities [no rules about endogamy/exogamy]
– exogamous communities (not clans) [exogamous]
– segmented communities (containing localized clans) with local exogamy [endogamous]
– clan communities (or clan barrios) [endogamous]

i collapsed these categories into either endogamous or exogamous, and then i combined the endogamous societies with the cousin marrying societies from above. i left the agamous communities (there were 66 of them) out of the final analysis ’cause who knows if they’re marrying in or out.

here’s what i found (click on chart for LARGER view):

of the exogamous societies, just about half have nuclear/stem families and the other half have some sort of extended families. of the consanguineous/endogamous societies, those having extended families number nearly double those with nuclear or stem families.

and the ratios of consanguineous/endogamous marriage patterns to exogamous marriage patterns are very different in each of the family-type divisions: endogamous to exogamous in nuclear family societies is about 2:1 while the ratio is more like 3.5:1 in extended family societies.

this isn’t a perfect analysis. a lot of the data in the murdock atlas is quite old, but it is still used frequently. and likely i screwed up along the way somewhere. but i think this is another indicator that, at the very least, there is a connection between in-marrying and clannishness.
