further to my notion that various jewish populations have tended to imitate the mating patterns (eg. cousin marriage or not) of the broader societies in which they have been situated — at least over the last millennium or so (dunno about the ancient hebrews) — here are some numbers on the types of cousin marriage found in the iranian jewish population. remember that consanguineous marriage is quite high among iranian jews — something on the order of 25%. from Outcaste: Jewish Life in Southern Iran [pg. 112]:

jews - iran- cousin marriage types

notice that nearly one third (3.06%) of all the first cousin marriages (9.88%) are to the father’s brother’s daughter (fbd or FaBrDa in the table). another 1.41% of the marriages are to other patrilateral parallel cousins, probably paternal second cousins. (that’d be father’s father’s brother’s son’s daughter marriage, if you must know. =P or ffbsd marriage! never mind. don’t think about it too hard.)

so ca. 4.5% of iranian jewish marriages are to a patrilateral parallel cousin to some sort. remember that patrilateral parallel cousin marriage (fbd marriage…or ffbsd marriage!) is very unusual. most of humanity avoids it. the vast majority of populations that practice cousin marriage practice maternal cousin marriage — usually cross-cousin maternal marriage or mbd marriage. it’s only the arabized world which favors parallel paternal cousin marriage (and the tswana). it’d be too much of coincidence, i think, for iranian jews to have invented fbd marriage all on their own — i’m betting they picked it up from other iranian peoples after the arabs introduced it to the region.

uuunnnnleeesssss…the jews (also?) introduced it to the region, as they are thought to have done in arabia. hmmmm…?

interestingly, persian jews seem to have put their own twist onto parallel cousin marriage and that is that they also marry maternal parallel cousins (mother’s sister’s daughter or msd marriage or MoSiDa in the table). that form of parallel cousin marriage is even more unusual than fbd marriage. i don’t know of any population that does it. nearly everyone on the planet avoids it. it might, however, have seemed natural to this group of jews — natural, that is, if you’re thinking of adopting parallel cousin marriage at all — since jews have had a very long tradition of allowing/practicing maternal uncle-niece marriage. there are more than two times the number of maternal uncle-niece marriage (SiDa) than paternal uncle-niece marriage (BrDa) in this persian group, for instance. (all of this harkens back to the idea that you know who an individual’s mother is, but you can never be sure who the father is.) i think this is another indicator that persian jews picked up the idea of parallel cousin marriage from the surrounding population (although perhaps it was back in the levant?), and then they adapted it to their own practices. could be wrong. Further Research is RequiredTM.

if (IF) i’m right — going by this persian evidence and the medieval german jewish evidence — that jews have generally adopted the mating patterns of their host populations, then an interesting question is, do other subgroups do this, too? will, for instance, muslim immigrants to the west adopt outbreeding? dunno. mixed signals here. in britain, where most pakistanis are from the kashmir and punjab regions, the total cousin marriage rate in the 1980s (that’s first and second cousins) was 67% [pg. 10]. the rate for all-punjab back in pakistan was 50.3% [pg. 16]. that certainly looks like an increase in cousin marriage in the immigrant population. however, meanwhile in norway, two studies found that pakistani-born pakistanis had higher rates of cousin marriage than norwegian-born pakistanis (37.5% & 34.7% versus 30.1% & 27.1% – pg. 11 – don’t know where pakistanis in norway are from). that looks like a decrease. all things considered, it’s probably too early to tell what the trend(s) might turn out to be.

korotayev and other russian anthropologists have argued — convincingly, imho — that father’s brother’s daughter’s (fbd) marriage was spread by the arabs, since its maximum range today (looking away from the outlier tswana in southern africa) corresponds to the eighth-century caliphate. they further argue that, as part of a more general “arabization” process, the conquered populations emulated their conquerors in all sorts of ways, both in order to succeed in this newly constructed society and, quite possibly, since they viewed the arabs’ culture as somehow superior to their own. the arabs were the conquerors, after all. they must’ve been doing something right! the arabs may even have impressed upon their new subjects that their culture was, indeed, the better one. if they’re right, it seems much less likely to me that immigrant groups to the west will copy our mating patterns if we don’t impress on them that we think they’re important and the right way to go.
