Note: Some “small talk” by me – “Transhumanisten” – (real name: Joern..) - at the end of this article..
Six Legs? A baby boy – Umar Farooq – was born with six legsin April, 2012, in southeastern Pakistan. International press noted that the boy’s parents were cousins, a common occurrence in Pakistan, where 70% of the marriage are “consanguineous.” Was the deformity caused by genetically-similar commingling?
Probably not. Polymelia (a rare genetic disease) was suspected at first, but eventually the extra limbs were blamed on an undeveloped “conjoined (Siamese) twin.” The reasons for conjoining are unknown.
Eyebrows were already raised around the world, though. Tongues wagged, netizens clucked. The consequences of “inter-breeding” are generally well-known: offspring from these unions exhibit abnormalities with greater prevalence than average, particularly when the practice is repeated for multiple generations.
What are the deleterious risks of consanguineous mating? Here’s a sampling: schizophrenia, congenital heart defects, pulmonary stenosis and atresia, cystic fibrosis, cystinosis, nephronophthisis, spinal muscular atrophy, albinism, achromatopsia, hearing disorders, central nervous system anomalies, congenital anomalies, physical handicaps, mental retardation and malignancies, added risk of infant and child mortality.
Statistics on the danger of ingrown genetics were publicized in 2005 when a BBC report claimed Pakistani-Britons produce 33% of the nation’s children with genetic illnesses, even though they account for only 3% of the births. (55% of Pakistani-Britons marry first cousins.) 10% of these newborns either die in infancy, or endure a serious disability. Pakistani-Britons who are first cousins are, claimed the report, 13X more likely to have children with recessive disorders than the general population.
This dire prognosis is duplicated in the US state of Ohio, in Geauga County, where the Amish population represents 12% of the citizenry. After inter-breeding for 300 years, Amish total 50% of the county’s special needs cases. Additionally, there’s a debilitating seizure disorder that’s so rare only twelve individuals worldwide are afflicted with it; the infirmity is exclusively Amish.
A recent book, Consanguinity in Context, by Alan H. Bittles, a medical geneticist at Murdoch University and the Centre for Comparative Genomes in Australia, has dismissed the hazard potential as inconsequential. Bittles claims the rate only elevates from 2-3% to 4-6% if parents are first cousins. A Saudi Arabian report also claims an elevation rise from merely 1.7 to 2.8%, and the London-based Human Genetics Commission claims the risk “rises to about six in every 100 births, i.e. double the risk.”
Why are these 2X stats so diminutive compared to the 13X greater risk of UK Pakistanis, and the 4X greater risk of the Amish? Why does the Human Genetics Commission state abnormalities of 6%, but BBC indicates 10%?
Bittles suggests that “environmental” factors elevate the rate of consanguineous birth defects. Another possibility, in my opinion, is that research simply can’t properly calculate increased risk, after centuries of shared genetic material in traditional regions, between cousins who repeatedly inter-marry.
First cousins related via a single channel are obviously far less at risk than those whose ancestors have interwoven DNA for 300 years (the Amish) or 1,300 years (Islam entered Pakistan in 712 AD.) It’s interesting that the Amish elevated rate of risk – 4X – is approximately 1/3 the elevated risk of Pakistanis – 13X – with this ratio near-duplicated again in their length of inter-marriage – 300 yrs / 1300 yrs.
Kissing Cousins Internationally
Worldwide attitudes on cousin marriage differ considerably, with the prevalence – both currently and historically – far greater than Westerners realize.
What nations define it as a no-no? Ethiopia appears the most prohibitive: it bans marriage between relatives out to 6th cousins. South Korea bans out to 3rd cousins; Taiwan and The Philippines ban first cousins, as does China, ever since it’s 1981 Marriage Act. In the USA, 31 of the 50 states ban first cousin marriage. In Europe and South America, consanguinity generally isn’t banned, but it is rarely practiced. Europe’s rate is generally less than 1%, and Brazil’s is presently 1.1%.
Where do cousins marry? Africa, the Middle East, and South Asia are the most consanguineous regions in the world, largely due to its general acceptance, even preference, in Islam. In India, the Muslim rate of cousin marriage is 22%, with the rate nearly doubling to 40% in Jammu and Kashmir. Pakistan, noted earlier, is the world leader in consanguinity with around 70%; Saudi Arabia is 50+%; Iran and Afghanistan are 30-40%, Iraq 33%, Egypt and Turkey 20+%, and Qatar 54%. Subsaharan Africa is estimated between 35-50%, with Nigeria’s opinion split tribally: Hausas prefer cousin marriage, Yorubas condone it; Igbos ban it.
Is the practice climbing or descending in popularity? In Qatar cousin marriage has increased 12-18% since the previous generation; it’s also increased in Morocco, Mauritania, and the Sudan, but it’s declining in Lebanon, Egypt, and Palestine. (These 2009 statisticswere compiled by the Dubai-based Centre for Arab Genomic Studies (CAGS), in a research project that also discovered that Arabs have one of the world’s highest rates of genetic disorders, with 66% of the abnormalities linked to cousin marriage.)
Today 1.1 billion people are either married to cousins, or the children of consanguineous unions, and 10.4% of humanity is second cousins, or closer. Why is cousin marriage so popular? It Always Has Been. Robin Fox of Rutgers ventures that, throughout history, approximately 80% of all marriages have been to first or second cousins. In the West, Charles Darwin married his cousin (Emma), so did Edgar Allan Poe (Virgina), Albert Einstein (Elsa), Queen Victoria (Albert), Franklin Delano Roosevelt (Eleanor), and H. G. Wells (Maria).
Reasons and Consequences
In the 19th century, several Rothschilds (the prosperous banking family) intermarried for one of the same reasons as many of today’s Muslims – Keep It In The Family. (I’m referring to the family jewels, double-meaning intended.) Assets accumulated via generations of hard work are deemed more secure if “outsiders” are not allowed matrimonial claims to the goods. Marrying within the family also guarantees that no unusual customs or ideas will waft in to threaten the established patterns, plus family ties are strengthened, negotiations are easier, and it’s harder to hide family secrets from potential in-laws.
Proponents of consanguinity like to boast that their divorce rates are low. Personally, I find these statistics meaningless because cousin marriages are nearly always coercive “arranged marriages.” Does love for one’s spouse keep cousin marriages together? Probably no more than spontaneous romance brought them together. The force that originally and permanently binds them is family pressure.
In the United States, cousin marriage was acceptable nationwide until an 1846 Massachusetts Commission implicated cousin marriage as a “retardation” factor. Twenty years later, a similar report from Kentucky linked cousin marriage to deafness, blindness, and idiocy. These early analyses were exaggerated, of course, but scientific reports indicate a lowering of IQ in cousin-marrying population groups. For example, in a study of North Indian Muslim schoolchildren the intermarried children’s mean IQ was 88.4, whereas the control group was 99.6.
The mental risk is convincing enough for me to list consanguinity as a hazard factor in two of my previous IEET essays, Brain Damage – 83 ways to stupefy intelligence, and Six Brain Damage Scourges that Cripple IQ in SubSaharan Africa.
With all this evidence stacked against cousin marriage, why does it persist? Don’t political leaders oppose it, or at least seek solutions? Indeed, they are. Instead of banning the practice, though, they recommend genetic counseling and screening. Every Persian Gulf state now requires genetic exams before marriage, with Qatar the last to mandate it, in 2009. Kuwait also established a new law in 2009, prescribing pre-marriage check-ups. Additional high-consanguinity nations that either promote or mandate premarital exams are Egypt, Syria, Tunisia, Morocco, Bahrain, Turkey, Saudi Arabia, Lebanon, Iran, and undoubtedly others.
Are counseling and exams just a frail bandaid? Are they truly effective? Are they capable of catching all the myriad genetic mines that lie hidden in our DNA? Why don’t governments just ban it? Yes, cousin-marriage is “traditional”, but with every new generation of inter-marriage, it’s dangers are amplified.
Ordinarily, I’d recommend an absolute ban, because I support eugenics that guarantee the maximum health of an arriving child, a position I staked out when I penned last year’s IEET essay, Ban Baby-Making Unless Parents Are Licensed. Obviously, there’s risk in cousin-marriages that can harm new life brought into the world. I believe society has an obligation to guarantee, to the greatest extent, optimal mental and physical health to every newborn. That’s what I want, so why don’t I insist on an absolute ban, right now?
I hesitate… because… I’d be a hypocrite if I adhered to that eugenic stance. The truth is, if there was legislation in my own nation that allowed only unions that were 100% safe, those laws…would have ruined my own family plans. Regard these sentences in Discover Magazine:
“…first cousin marriages entail roughly the same increased risk of abnormality that a woman undertakes when she gives birth at 41 rather than at 30. banning cousin marriages makes about as much sense, critics argue, as trying to ban child-rearing by older women.”
Among the “critics” is the Human Genetics Commission:
“the effect of increased maternal age on the rate of Down Syndrome… can be compared with the increased risk of consanguinity. At 35 years of age the risk of Down Syndrome is four times that at age 25 and it increases 15 times by the age of 40… [Both] cousin marriage and increased maternal age… represent complex cultural trends…”
Yikes! My youngest daughter – Zenobia – emerged out of my wife’s 40-year-old womb…
Zenobia also endured added risk due to my contribution, as an Older Dad – I was 51 when she was born. Men that age are guilty, according to studies, of fathering children that have an increased risk of mental illness, “especially autism and schizophrenia” because “the rate of genetic mutations passed on via their sperm cells increases significantly.”
Would I be a fraud, a phony, a total charlatan if I denounced cousin marriage but condoned older parenting? Perhaps, but… my wife and I did pay for amniocentesis, to determine if the fetus had abnormalities. I advocate that this exam and other tech interventions be governmentally paid for via health policies worldwide.
Additionally, I suggest that spunky teenage or early 20’s lads store frozen spoonfuls of their spermatozoa, for procreation use in their later, declining years. I had my sperm analyzed at 50, before I contributed it for conception, and indeed, it had a high percentile of headless and errant split-tail polliwogs, graphically illustrating that my half-century sperm just wasn’t as robust as it was when I was nineteen.
Returning to the question of banning cousin marriage… a prominent Western foe of that notion is Alan Bittles, the Consanguinity in Context Consanguinity in Context author. He argues, quite logically, that “People with severe disorders like Huntington’s disease, who have a 50 percent chance of passing it on to their offspring, are not barred from marrying because of the risk of genetic defects… so cousins should not be, either.”
His mathematical and ethical reasoning is absolutely right. If governments decide to keep people from reproducing because offspring can be disabled, they need to start with the riskiest couples.
Cousin-marriage, in my opinion, is also undesirable for reasons beyond genetic risk. Culturally, I also deplore the practice because it’s almost always arranged, without romance, between the two passive parties. (Bruce Charlton MD, professor of theoretical medicine at the University of Buckingham, posts this equation on his blog: Cousin marriage = arranged marriage = coercive marriage. I want everyone to enjoy, suffer, and endure the sharp drama and sweet, tawdry thrills of flirtation, seduction and courtship. Cousin marriage springs, overwhelmingly, from societies that repress freedom to love.
The clannishness that cousin marriage supports is also stifling to civic democracy, because family members align themselves with the interests of their in-grown family, instead of allegiance to the state. Libya’s “Arab Spring” revolution featured the nation’s schism into 30 major tribes or family clans, and Somalia’s longtime anarchy is essentially a tribal feud between clan warlords, i.e., family leaders. Isolating family members from the ideas, economics, and genetic components of other clans also devalues political debate and stymies meritocracy due to nepotism and corruption.
But… still… outlawing cousin marriage? Is this necessary? Aren’t government-funded pre-natal and natal examinations enough? No? In the long run, is it best to just toss cousin-matingon the scrap-heap of anthro-history, like trepanning? Are all measures less, just promoting dangerous eugenics?
Note my bracket above around “cousin-mating” – because that’s what we’re actually talking about, not the indirect euphemism, “cousin-marriage.” I have few qualms with cousins marrying-but-not-propagating, co-habitating in legal unions, without children between them – there’s no injury there, no harm to others. If they desire offspring, there’s safe, unrelated sperm or/and safe, unrelated eggs that can be purchased. Legislation in this direction is undoubtedly useless, though – married couples almost always want children genetically linked to themselves. I sympathize, but is it fair to the child if this mixture is debilitating, disfiguring, mentally crippling, and/or lethal?
Is Change Possible?
Does the half-way solution – genetic testing for cousin couples – actually work? Largely, overwhelmingly, NO. The UK’s National Health Service (NHS) provides genetic counseling to consanguineous couples, but that 13X factor that the BBC reported suggests that the option is generally ignored. Why?
Many, or most, Pakistani-Britons are distrustful of the white establishment’s warnings. Disdain is evident in this posting by “Iftkar” on Sunniforum.com:
“Cousin marriage is common in all Muslim countries… in accordance with the teaching of the Holy Quran…. Children are born with defects whether it is cousin marriage or not. Among migrant Muslim communities the defects are due to many factors. The pressure of moving to a different cultural environment and moving from their families, problems of racism and employment are responsible for the defects during pregnancies. The defects are nothing to do with cousin marriages. The hidden agenda is that British society does not want Muslims to bring their spouses from Muslim countries. A man/woman has the right to marry anybody from anywhere. It is a question of human right and the right given to Muslims by the Holy Quran and the sayings of the Holy Prophet…. There is no hard evidence that married to cousin causes birth defects. Before picking on Pakistanis just remember that Queen and Prince Phillip are third cousins. Glass houses…stone…. it is another witch hunt against Muslim community…”
Another barrier that’s perhaps even more imposing than cultural distrust is found in a a Saudi study that discovered, “90% of couples detected as carriers did not follow the advice they were given and went ahead with their marriages.” Couples aimed at matrimony, it seems, either believe in “fate” or in odds that will favor the health of their family.
So…what is to be done? Here’s advice:
1. More aggressive education about the hazards of consanguinity
2. Promotion of cultural alternatives
3. Obtain support of the consanguineous culture’s leaders
4. Accelerate advances in pre-natal and diagnostic technology
5. To Guarantee Trust – the warnings, counsels, requirements, and restrictions must be distributed in an egalitarian manner to all cultures, especially to the dominant majority. Couples who are carriers of severe genetic disorders need to make sacrifices first, because their offspring are the most at-risk.
Oldsters like me? If a fair nation wants to mandate against cousin marriage, it’s citizenry of age-50+ wannabe-Dads and age-40+ wannabe-Moms needs to be scrutinized, as well. Storing sperm and eggs when they’re young is a commendable strategy.
Perhaps in the future, children like Zenobia will be conceived and gestated, far more sanely, in test tubes and artificial wombs?

As the author of this article points out, Pakistan “is the world leader in consanguinity with around 70%“. With “1.1 billion people either married to cousins, or the children of consanguineous unions“, this is clearly a world-wide phenomenon, but it occurred to me that I’ve been bombarded with negative news and stories about the ugly face of Pakistan lately, so I thought I’d add something a little more uplifting..
For starters.. I bought me a new pair of sunglasses.. – I’m telling you because I bought them from a Pakistani guy, – a very nice guy with a winning smile, – but then of course his main concern was most likely selling me this particular pair that he claimed looked perfect on me.. – Now, since I agreed with him.. and it was a nice sunny day and I was in a really good mood, I not only bought the sunglasses, but started chatting with the guy, which is how I found out he was from Pakistan.
I mentioned the arrest of the Pakistani doctor who helped CIA trace Bin Laden, to which he replied: No-no, – that was NOT Bin Laden, – he died 4-5 years ago.. – I realized the futility of arguing with him, so we carried on with some small talk, and I told him about my first visit to Pakistan, – in the 70′ies..
Back home, I felt like reassuring myself that my new sunglasses really did look perfect.. – I can’t say I was wholly satisfied, but anyway, here’s a couple of snapshots I took with my webcam:
No ? – Well – ok then, – perhaps you like Veena Malik, Pakistani actress, model and comedienne, better:
For more “uplifting” stuff, also check out Pakistani-Norwegian comedian and famous “Mullah-lifter”, Shabana Rehman .
I was thinking also.., the beautiful northern border regions of Pakistan – the original Shangri La.. – is not just where the Taliban run to and hide.. , but also home to the Hunza people – the Hunzakuts – of whom many are reported to live well beyond a hundred years and who have a reputation as some of the world’s healthiest human beings.
Oh – and by the way, – they don’t inbreed, – according to this free ebook: The Healthy Hunza. I don’t know how trustworthy it is, but here’s a taste from the book:
“Rarely does a Hunzukut marry a first cousin. They keep their running water pure and know the value of general cleanliness and sanitation. They lead a vigorous out-door life, thus exercising their lungs. Much of their time is spent out of doors where they breathe in pure air.
The Hunzukuts do not take medicines, headache pills, or physics”…
Finally, some beautiful photos from the Hunza Valley :
