You can take people away from incestuous populations but you can't take incest away from incestuous people.https://twitter.com/DRUDGE_REPORT/status/1054808650542239744 …

not all somali pops practice(d) cousin marriage (traditionally). northern somali groups avoided it, southerners preferred it. bucking the trend, it's the northern *pastoralists* who avoid cousin marriage, while the southern sedentary groups favor it.

Could you send us the reference for that differences between northen and southern Somalies? AGVP dataset shows that Somali presents systematic inbreeding.

the anthropologist i.m. lewis is your man. he spent much of his lifetime studying the somali and other pops in the horn of africa. here from Blood and Bone: The Call of Kinship in Somali Society (https://books.google.com/books?id=9fAjtruUXjEC …):pic.twitter.com/Au6EA5iFws

Yeah... I'm familiar with all his work, also that book. However I'm not sure how accurate his conclusions are... specially after analysing ROH in the Horn of Africa. Thank you very much thought! I appreciate it!

oh, right! did you (you guys) have samples from these northern groups he surveyed? he did mention somewhere (i think in Blood and Bones) how the practices could change, like during the wars of the '90s lotta these clans shifted to patrilineal cousin marriage...

...maybe the out-marriage practices he observed just happened to be favored in the time he happened to be there? a snapshot sort-of thing?

To tell you the truth I need to check again where the samples were collected. However ROH profiling analysis does not show that swift. Are northen somalies islamic?

Replying to @Ceballos_Gene
yes, they are. which was one of lewis's points: he observed that there was a variety of marriage prerferences and practices between these islamic groups wrt to cousin marriage and concluded that islam was not the main factor pushing for endogamous practices in horn pops...

...but who knows how long they've been exogamous for? ¯\_(ツ)_/¯ korotayev makes a similar argument, btw: that father's brother's daughter marriage in mena muslim societies is not really due to islam, but, rather, arabization.

This is indeed very interesting and way more juicy than said all islamic populations practice systematic inbreeding... We need more samples hahahaha. Saddly the AWI-Gen effort does not have many Somalies...
