Friends Have Closer DNA Than Strangers, Scientists Find

Sarah Knapton, Telegraph (London), July 14, 2014

Blood is supposed to be thicker than water, but a new study suggests that friends are as genetically close to us as members of our own family.

Researchers who compared the DNA of unrelated friends were intrigued to find they had the same genetic similarity as fourth cousins, or people who share great-great-great grandparents.

The finding remained even after controlling for ethnic, cultural and geographical bias.

“We are somehow, among a myriad of possibilities, managing to select, as friends, the people who resemble our kin,” said Nicholas Christakis, professor of sociology, evolutionary biology, and medicine at Yale.

The researchers looked at 1.5 million markers of gene variation and found that friends are most similar in genes affecting the sense of smell and least compatible in genes controlling the immune system.

Recent studies have found that people appear to choose partners based on differences in immunity.

It has been suggested that forming social groups with others who are able to withstand different pathogens reduces the spread of disease and increases the chances of survival.

“Looking across the whole genome we find that, on average, we are genetically similar to our friends,” said co-author James Fowler, professor of medical genetics at the University of California.

“We have more DNA in common with the people we pick as friends than we do with strangers in the same population.”

The academics believe that choosing friends who are genetically similar may convey ‘evolutionary advantages.’

“The first mutant to speak needed someone else to speak to,” added Prof Fowler, “The ability is useless if there’s no one who shares it.”

However the mechanism for selecting friends or a mate based on genetic traits remains a mystery.

Previous research has suggested that pheromones in sweat carry important clues to genetic compatibility and are important to attraction. There are fears that modern medicines, like the pill, dampen down this natural selection process.

The so-called ‘smelly T-shirt experiment’ first performed by Swiss zoologist Claus Wedekin in 1994 found that women preferred the sweat of men who had immune systems the least like their own.

But Professor Dan Davis, of the University of Manchester, who recently published The Compatibility Gene, said attempts to repeat the experiment had shown mixed results.

“It is fascinating that there seems to be some underlying biology going on, but this area is very controversial and the evidence of this in humans is still extremely weak.

“It is certainly feasible that genetics is driving some kind of selection behaviour. We see it in animals but in humans there are so many other factors to consider that the findings have been inconclusive.”

Professor Fowler believes there may be a simpler explanation as to how people with similar genes meet and form friendships. People who like the scent of coffee, for example, may hang out at cafés more and so meet and befriend each other.

The researchers focused on 1,932 subjects and compared pairs of unrelated friends against pairs of unrelated strangers.

They found that the genes that were more similar between friends seem to be evolving faster than other genes.

Profs Fowler and Christakis say this may help to explain why human evolution appears to have speeded up over the last 30,000 years, and they suggest that the social environment itself is an evolutionary force.

“It seems that our fitness depends not only on our own genetic constitutions, but also on the genetic constitutions of our friends,” added Prof Christakis.

The team has even developed a ‘friendship score’ which rates how likely two people will be friends based on their DNA.

The findings were published in the journal Proceedings of the National Academy of Sciences.

  • Researchers who compared the DNA of unrelated friends were intrigued to find they had the same genetic similarity as fourth cousins, or people who share great-great-great grandparents.

    Maybe two “unrelated” people who form a platonic friendship actually are some sort of distant cousins. Friends generally grow up, live and work in the same area, so the odds of some sort of very loose biological relationship between them, x cousin y times removed, is pretty high.

    It’s like whenever we get a new President. Geneology will show him (or eventually her) to be x cousin y times removed to this former President or that former President. Barack Obama and Dick Cheney are straight eighth cousins. Some ignoramii chalk that up to some conspiracy or a secret society, when in reality a nation is merely a group of very loosely related very loosely inbred people. Any two white people or people with enough white ancestry (such as Obama) that the country could vote in as President are almost 100% likely to have some x cousin y times removed relationship. It’s also the case that the white (or part white) person that is elected President and a white person who cast a vote in that election are almost 100% likely to be x cousin y times related. Just like two individual white voters on that same election day even if they’re on totally opposite sides of the country are each other’s x cousin y times removed.

      Studies I have read have pointed out that the best genetic matches when it comes to the strongest reinforcement of most traits are of 4 and 5th cousins.

      The book, “Before the Dawn” points out that out-breeding, that is, mixing opposites black and white, etc.) actually stagnates the evolutionary process because it reduces the number of mutants in any particular gene. So inbreeding was necessary to produce mutants that could then be selected for naturally. In the past, there was just enough genetic drift to retain an overall healthy gene pool just about anywhere while still preserving the characteristics of a racial, ethnic group. Many Europeans (or people that have lived or traveled extensively there (at least in the past), could tell you that even within countries, even small ones, there were certain regional “looks,” just as there were so many regional dialects. But that genetic drift has turned into a tidal wave, which, along with many other out of control conditions appear to this observer to be the crescendo preceding a very messy and far-reaching collapse.

            The founders of Europeans in North America were actually overwhelmingly Norman rather than the usual assumption of “Anglo Saxon” due the to the dominance of English in North America. There are some very succinct genealogical tomes that illustrate this such as “The Norman People in North America,” among other recognized genealogical references. The Normans were a remarkable people and I am very proud to have my direct ancestry back to them.

            I don’t view everything that the Norman’s did as particularly righteous or even right or fair. I have a lot of sympathy for the Irish and many other groups our Norman ancestors conquered and/or “managed.” But for better or worse, much of the order (and therefore disorder) or the modern West was due to the brilliance and aggressive inquisitiveness of the Normans.

            I was referring to much more subtle signs. You’re very funny, but miss the entire point. I am white and have blue eyes, but a German postman in Bavaria knew I was an American before I spoke. People used to vary in a place like England from shire to shire, village to village.

          I meant even within those groups. I lived in Slovenia for a couple years in the late 90s, a country half the size of Switzerland. I was told that there were actually 60 dialects of that already small language. I heard a couple very old jokes about how the people from the other side of a ridge in the Julian Alps (part is in their territory) looked and acted. One activity on Saturday night was for the young men of one town to go to another and fight with the young men there, street fight.

          I was married there. Wedding parties can last up to three days. One old tradition is that the towns would barricade the bride inside and the groom also trapped inside, had to bribe the brothers in order for them to allow her to leave the village. I was told that in older times, it was considered a great shame to marry anyone outside of the village. They have a lot of fun with it at weddings today. My own wife was “stolen” from our wedding reception around midnight. We had to hunt her down, going from village to village at gostilnas (guest houses – with bar and grill). We searched a ruined castle, we climbed up a foothill trail that led into the Alps. We ended up bartering for her with drinks at the gostilna where we finally found her after I stole the keys from the kidnappers’ car.

          • Martel

            Great story, I should take a few trips to Slovenia.

          • Whiteplight sees the Emperor N

            It’s so all over the Balkans and up into Hungary and Austria. One joke I heard from a Serb in 2000, on a trip back was in referrence to that F-17 that was shot down by mistake during the NATO bombing campaign in 1999 (which I was a witness to). The joke: “How was the American jet shot down?” Ans: “A wedding party.” Serbs are the most famous for three day, outdoor wedding parties and the men that shot their pistols in the air during the festivities.

          • Whiteplight sees the Emperor N

            Well, don’t show up for a Saturday night fight in some village unless you want to get a knock or two. The men in Slovenia view scars as manly and don’t mind getting a few. They even regard surgical scars as macho.

        “Many Europeans (or people that have lived or traveled extensively there …) could tell you that even within countries, even small ones, there were certain regional ‘looks,’ just as there were so many regional dialects.”

        Yes, indeed. Having lived in Europe I know exactly what you mean. You quickly come to recognize and distinguish certain local forms –– people who are so uncannily alike in their appearance, facial features, mannerisms, posture, etc. that you instinctively know their ancestors must have originated in the same village or manor.

        • Ella

          When you have descendants that live in one region for 1000 plus years, they will have some strong ethnic-features and commonality. I can easily find some of my ancestors who lived in a small German town for at least 700 years using church records.

            In my many starred history of loves lost, the most tragic one was a particular young woman that I was so desperately in love with and suffered so much when it didn’t work out. We spent many moments gazing deeply into one anothers’ eyes. Many years later, decades, when I finally delved into my own ancestry, I found that the region of Lorraine that my ancestors came from had to be the same as hers because her surname was the same as the village that was only a short distance from where my ancestors inhabited in 1600.

      Forcing different people to get along results in a Yugoslavia.

      • benvad

        How really are Croats, Serbs & Bosnian Muslims that different? I’d seem them more or less the same as Irishmen, Ulstermen (Paisley’s people) and Scots. I just don’t get the White inter ethnic hatred, it just bothers me to no end over a God damn difference in a denomination or a different language, it’s just so sad.

        • Whiteplight sees the Emperor N

          To answer you, yes they are. And they sure do see themselves as different. For one thing, the Bosnian Muslims are Turks in origin. But you can blame Christianity for the rest of the divide. You ought to read up on the history of the Balkans. A deeper education will help you realize that their identity is what matters to most people and that their different identities are caused by different history. In the case of the Balkans, conflicting history since ancient times. It’s a place where ancient empires overlap.

          I lived there and I can tell you that Serbs, Croats and Slovenes, get along pretty well. tito the dictator/ruler of Yugoslavia made the error that all ego-centric dictators do; he forgot to groom anyone for the leadership role once he was gone. As it was, the last ten years of his life was weak and Yugoslavia was corrupting.

          Of the war in the early 90s my dear friend there said, “When Tito was gone, all the worst people came out.” The Muslim Albanians are much like the Mexicans are for us here, as are the Montenegrins. It was the Albanian mafia that was doing the most heroin smuggling when I lived there (late 90s), but the Russians were there, too.

          A good, quick introductory read on the subject is Robert Kaplan’s “Balkan Ghosts.” The real epic read on the subject is the remarkable Dame Rebecca West’s “Black Lamb, Grey Falcon, A Journey through Yugoslavia.” Written in 1940,. on the eve of WW2, it takes you on a historical tour while the events of she and her husband’s travels take place in a atmosphere of impending conflict.

          • Garrett Brown

            Balkans were catholic long before any of them were forced to convert to Islam. Turkey (Byzantines) was catholic until Muslims swept over the land like a plague and sacked Constantinople.

          • ElComadreja

            There were also forced conversions of Greeks and other peoples during Ottoman rule.

          • Garrett Brown

            Yes. That entire area was ruled by the Byzantines who were the Greek speaking half of the Roman Empire. When they took over Persia and Arabia the people were still polytheistic in belief. People don’t do their homework/research and think those territories have always been middle eastern influenced. The fact is Europe has been under siege, and this reduced significantly, for centuries.

          • Whiteplight sees the Emperor N

            That’s right, it was Alexander the Great that established the Hellenic period of influence in the Middle East and beyond. We must remember that Egypt was ruled in Alexandria by a Greek dynasty up to the time of Cleopatra. The Greek schools of philosophy, including the pursuits of science and math were re-introduced into Europe after a long period of darkness caused chiefly by the superstition and hysterical fear of the Christians in what history terms the Renaissance, when the ancient philosophies were finally allowed to stand in the full light of day again in Europe.

            The real tragedy is that the non-stop efforts of the Turks to enter Europe led to the destruction of many nearby Caucasian peoples and cultures, the Circasians and Georgians among others. As these religious fired wars of conquest raged on, the resisting whites were polarized more deeply into their own religious superstitions. Rebecca West’s “Black Lamb, Grey Falcon, a Journey through Yugoslavia” contains some very descriptive examples of how historical/religious myths evolve during hundreds of years of national struggles.

          • Whiteplight sees the Emperor N

            Worse than that, Serbian women were systematically raped and forced to raise the resultant children as Muslims. These children were given favorable positions of power in Bosnia to rule over Christian Serbs for 400 years. Today, they are identified as the Bosnian Muslims.

          • Zaporizhian Sich

            And that is why Serbs hunted them down and killed them during the wars fought there in the 1990’s, war in which the U.S. bombed Serbian civilians deliberately. Damn right the Serbs hate the Bosnian Muslims, they have every right to.

          • Whiteplight sees the Emperor N

            I’m sorry, that is not really correct at all. The Balkans were Orthodox Christian, not Catholic. Only Croatia and Slovenia were ever Catholic and they were part of the Austrian Hapsburg Empire.

            A major cause of the world wars was the Catholic Hapsburg betrayal of the Orthodox Serbs when they finally rebelled successfully against Turkish rule. In 1878, the Hapsburgs colluded with the Ottoman Turks, who had previously fought a war to prevent the Turks from entering Europe for 400 years to suppress the Serbs. The Serbs, especially the Bosnian Serbs were brutally suppressed. They were shocked because they had expected the Hapsburgs to support them due to their common Christianity. This led to a revenge cycle that saw the secret society, “The Black Hand” come into being, which was aimed at revenge against the Hapsburgs and their rule. Gavrillo Princip was a member of that secret order. He is the one who shot the Archduke Ferdinand and that is what started WW1. The rest is well known history.

          • Garrett Brown

            They were under the Byzantine empire, therefor they were Catholic.

          • Whiteplight sees the Emperor N

            Wrong. The Easter Empire was always Orthodox. Check Gibbon’s “The Decline and Fall of the Roman Empire” and any other reliable history source.

          • Garrett Brown

            What’s an Easter empire? To reply to your original comment, which I supose you edited because you realized how ignorant it was. No, the Byzantine empire wasn’t always orthodox. Only after the split in 1054 did the Greeks recognize themselves as orthodox. It’s called the great schism. The majority of Balkan people continued to remain Catholic.

          • Whiteplight sees the Emperor N

            You know that it was a simple typo and Eastern was the word. I corrected it because of that and you know it. Having to use that as a weapon to attack my credibility only reveals how little substance you have in your own argument.

            You’re still wrong. There was no Catholic Church in the 4th century. I again refer you to Gibbon, if you even know who he was and what his work is.

            To claim that the Slavs in the Balks were ever Catholic is a huge error. Only the Slovene and Croats were. Everyone else was Orthodox in form and later the Serbs were and are Serbian Orthodox (as they call themselves). I am an unbeliever, but in 2000, while on a visit, I asked a Serbian friend of mine to take me to her church with her sot hat I could observe the Serbian culture closer. Don’t try to tell me about it.

            The schism you refer to was only formal. The Eastern and Western forms had been arguing for centuries. Look it up. My point stands that Constantinople was never Roman Catholic or “Catholic” by description, it was just “The Church” before it settled upon Eastern Orthodox (from Greece up the Eastern Balkans, including The Kingdom of Serbia and into Russia. The Greek Orthodox used Greek and when “St Cyril” invented Cyrillic to convert the Slavs from the Balkans up to Russia, Cyrillic became the alphabet of the Church and Latin NEVER WAS.

          • Zaporizhian Sich

            Not true, Byzantium was the birthplace of Eastern Orthodox Christianity, the Serbs never were Catholics. By the time Crown Prince Volodymyr made Orthodox Christianity the state religion of Kievan Rus in 988 A.D., Catholics and Orthodox Christians have been going separate ways for centuries. That had it’s origins long before the western Roman Empire collapsed, by the third and fourth century A.D. the eastern half of the Roman Empire was very different from the western half and thus independent of Rome.

          • silviosilver

            The question was not whether they see each other as different but whether they are in fact different. Since racial differences between the groups – particularly within Bosnia itself – were for all intents and purposes non-existent we must conclude that genetic similarity of itself is an insufficient social glue.

          • Whiteplight sees the Emperor N

            You are incorrect in your premise. Bosnian Serbs are genetically different. As I posted above, the Ottoman Turks systematically raped Serbian women and forced them to raise the children as Muslims. These children were given bureaucratic rule over the Christian Serbs for nearly 400 years. So it is not simply that they are separated by different religions, they are separated by genetics and by a brutal history. However, when I was working in Slovenia, I saw that many of all these people get along day to day, while privately carrying on in full knowledge and resentment of their history.

        • benvad

          Mr.Anonymous I get I get it, but this infighting is what the hordes and Tribe wants us to do. When the Balkans are inundated with filth from Africa & Middle East, then I think past grievances won’t be quite so important.

            You’re almost certainly correct. I would prefer to see comments like Whiteplight’s, which use race as a way of pursuing narrow ethnic agendas, either banned or heavily discouraged. At the very least commenters themselves can point out the behavior, which is rife among Balkans posters.

            I know a few serbs (actually dated one) and knew Croats and Bosniaks (They weren’t Turks just traitors to Christianity for monetary gain), hell I got al;ing with all of them and I would say the majority (apart from a few nationalists “read Croats”), were very positive about Yugoslavia. I miss that union, I really believe it was a good thing in hindsight.

          • Whiteplight sees the Emperor N

            The Bosnians were the children of raped Bosnian Serbs. They were given positions as tax collectors and managers over the Serbs during the time of the Ottoman rule. Read up on it.

            You also obviously don’t know much about the nationalism of the Serbs, Albanians, Slovenes, etc. The Slovenes are probably the mildest and they are nationalistic as any nazi (without the desire to conquer or harm others).

            Yugoslavia has been written about a great deal. The conclusion of many seems to be that it was impossible for many reasons, one being that the Serbs believed themselves to be the natural dominant leaders of Yugoslavia and the others didn’t agree. Tito was Croatian and was a good example of a brilliant organizer, but he balanced Yugoslavia by moving Albanians into Kosovo to suppress the Serbs. Kosovo was the site of the Serbs most holy sites and the location of the legendary battle where Prince Lazar lost to the Ottoman Turks. Then Tito forgot (as all megalomaniac rulers do) to groom his successor. So when he died, a suspended, artificial creation had to collapse.

            But don’t worry, today, everyone is more or less settled into peaceful coexistence. It is the waves of immigrants from Africa and the East that will challenge them all next.

          • Whiteplight sees the Emperor N

            Banned? Heavily discouraged? By what petty dictator with what sort of understanding of what constitutes a culture? If there is anything becoming more clear all the time, it is that the American idea of a melting pot eventually backfires and in a huge way. But you don’t seem to understand the issue being discussed. The Balkans have a very complex history with oppression as a main feature. More oppression of people that fiercely believe in their right to rule themselves by even a well meaning (Napoleon) will be fought as furiously as against the Ottomans or anyone else.

            It is exactly that we must work to preserve every small culture within our family of Europe with all their glory, in order to save whites in general. It is being objective and educated and HONEST enough to recognize what has been the cause of ethnic wars among whites and act to that, not some borrowed impossible leftist utopian ideal that will work if we can force it to.

          • Whiteplight sees the Emperor N

            Of course, the Balkans are a great example of what is likely partially behind the EU thought where non-European immigration has been concerned. They imagine as do liberals in America and Canada, etc., that they old problems will disappear if they can overwhelm those populations with Africans and Muslims. They hope that enough genetic delusion will occur to make issues unrecognizable.

            What they didn’t figure on was how difficult to manage and how completely unfit these peoples were to ever be considered capable of assimilation. Now, everyone is slowly realizing the mistake, but hesitate at the realization of the drastic measures that will be necessary if anything is to be saved.

    ” Friends generally grow up, live and work in the same area, so the odds of some sort of very loose biological relationship between them, x cousin y times removed, is pretty high.”
    Thought the same thing. The probability would be even higher in more isolated areas, such as small rural towns, where there is less in/out flow. Interesting stuff.

  • italian guy

    Well it’s not that surprising, i don’t remember where (maybe it was on vdare) , but i have read a definition of race that i think it’s pretty accurate: a racial group is a partly inbred extended biologically family.

    • Whiteplight sees the Emperor N

      Inbred, or inbreeding has become a negative term, something to snicker about and accuse your enemies of. But, without it there would be no human beings, no races, and certainly no white people and certainly, certainly none of the extraordinary characteristics in whites that continue to see whites as both hated, envied and imitated.

      The way genetics work, as the races mix more and more, there will be less genetic mutations present as opportunities for the natural selection process. So as the races mix, evolutions grinds to a halt and may even be reversed (if you see the minority being deluded by a less evolved majority).

      • italian guy

        Funny how the people who don’t believe in race, suddenly believe in genetics when it’s time to accuse “racists” of being inbred.

    Quite unintentionally this happened to me. The best friend I have made as an adult has not only been mistaken as my brother, but is also of Hungarian descent. Weird.

    It would be my guess that blacks have more closely related DNA because none of them know all of who they are related to and they breed indiscriminately – nothing like having sex with your half sister / brother from a different mother.

      As they say, Father’s Day is the most confusing day of all for blacks.

    Imagine that, human beings being tribal and self-segregating. Who would have thunk it?

  • Petronius

    “The academics believe that choosing friends who are genetically similar may convey ‘evolutionary advantages.'”

    “The greater the danger is, the greater is the need to reach agreement quickly and easily about what must be done; not misunderstanding one another in times of danger is what human beings simply cannot do without in their relations. In every friendship or love affair one still makes this test: nothing of that sort can endure once one discovers that one’s partner associates different feelings, intentions, nuances, desires, and fears with the same words.” – F. Nietzsche, “Beyond Good and Evil”

    This could be explained by the Selfish Gene theory. You invest more heavily in (i.e. are friends with) people who share the most of your genetic make-up, increasing the chances for your genes to make it to the next generation. After all, the gene doesn’t “care” weather is its copy from your body or your friends that “makes it”.

    I don’t see why an endogenous identification mechanism would be strictly necessary, since our interests seem to have a strong genetic causation already and we tend to associate more with the people who share our various preferences and interests.

    This study is obviously rubbish. Don’t they know that all humans share 99.8% of their DNA?

    One survey shows that we are closely related to friends. Another survey proves that we are married to those who have immune systems quite different than ours. No one bothers to explain or even note the contradiction of these two ‘scientific’ surveys, in an article dedicated to the issue. More of that good old ‘science’ in the main stream press.

    Okay I’m here and I’ll say it.

    Pressing a button to make someone your friend is the sine qua non of modern life. It and comprehensive immigration reform and quantitative easing will combine to make me the world’s first trillionaire. My bank accounts in my extradition free tax haven means that the American government will never see a dime of it, because as we all know, taxes are only for the little people.

    If you think I’m the least little bit worried about the millennials leaving Facebook, then you’re thinking wrong, my enemy. They’re leaving because their parents are coming. And their parents are in the 25 to 54 age range that advertisers drool over. Which means Facebook is going to be able charge even higher rates for advertising, drawing even closer to the day that my personal net worth hits thirteen figures.

    What’s mine is mine, and what’s yours will soon be mine. Middle class greed hurts billionaires in need. And most importantly of all:

    Make my immigration reform comprehensive, please!

      Yeah, kids can be counted on to flee anything that older people get into. But kids grow up and money does talk. I don’t think that the kids have the social power they imagine. They never did, even in the 60s (and I saw that).

  • Whiteplight sees the Emperor N

    I hope you’re right.

  • Whiteplight sees the Emperor N

    After all, they had the same animus in you.

    Thank you!
