Possible Monogamy Gene Found In People
Calopteryx sends in a New Scientist summary of research from Sweden pointing toward the existence of a gene that influences monogamy in men. (The article doesn't mention women, and the study subjects were all men at least 5 years into a heterosexual relationship.) "There has been speculation about the role of the hormone vasopressin in humans ever since we discovered that variations in where receptors for the hormone are expressed makes prairie voles strictly monogamous but meadow voles promiscuous; vasopressin is related to the 'cuddle chemical' oxytocin. Now it seems variations in a section of the gene coding for a vasopressin receptor in people help to determine whether men are serial commitment-phobes or devoted husbands."

I see a whole brave new world of testing before pre-nuptials . . . But, if I have a defective gene, will that qualify me as handicapped under something like ADA? Will there be a high risk pool that I will be forced to "date" out of? So many questions . . .

In the early 60's we got birth control pills, which (some say) facilitated women being promiscuous. Now, we have 'husband control pills'

In my case, it's a "Martha" that has the greatest influence over my monogamous inclinations.
You don't use science to show that you're right, you use science to become right.
They also found that geeks tended to possess just half of this gene, which researchers postulate may explain their lack of ability to get a girlfriend.

monogamy in general seems to be a mirage
there are of course places in the world where polygamy is openly accepted, but in places where monogamy dominates publicly, everyone is polygamous in secret
and i am talking about men AND women. male polygamy gets more attention only because male polygamy is more public, male sexuality full of more bravado. women are just better at keeping secrets
and it makes perfect sense for men and women. men for for the obvious ability to spread more genes, and women for access to more resources, or simply to get better genes in secret than the genes of the publicly acknowledged mate (it has been speculated something like 10% of children before the era of genetic testing were raised by fathers who weren't really their genetic fathers)
i think that any gene that regulates vasopressin simply regulates how discrete or not discrete a male is going about being secretly or openly polygamous
there is just too much incentive, genetically, to spread your seed as wide as possible, no matter what
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it

Wait until after you've had sex to make that call.

Just as a guess, which strategy works better (from a 'survival of the genes' perspective) probably varies in different circumstances. This would explain why neither gene sequence has dominated.

Shouldn't evolution sided with either monogamy or polygamy? I mean even if there is only a one percent difference between the successor rates should that have not been reflected by now?
If monogamy or the lack thereof were genetic and there were an evolutionary advantage to either strategy, then you're right: that should have been reflected in the general population.
Since it doesn't seem to be, that would seem to indicate that perhaps there is no evolutionary advantage to either side. With no advantage, there is no pressure for humanity to tend in one direction or the other. That could yield a pattern closer to what we are seeing now.
No. It shouldn't have, because either strategy can lend itself to evolutionary success for men.
If you're a powerful man, polygamy is an excellent strategy. You want to be impregnating every woman you can get your hands on, and you can by force and/or intimidation (among other motivators). Genghis Khan is an exemplar of this (at least according to one study that something like 6% of the world's men are his descendants). With that many kids, you don't need to invest very much in making sure each kid survives long enough to reproduce.
If you're a powerless man, then your best strategy is monogamy: you aim to have one woman who you reproduce with, and devote lots of time and energy into making sure that those kids survive. This leads to the nerds who will love a woman forever and stick with her through sickness and health.
If you're somewhere in between on the power scale, then the strategy seems to be pretending monogamy while having at least one mistress on the side. The theory here is that you get the greater number of kids and genetic variation from having more partners, but a fallback position of the kids from your "monogamous" relationship. Hence middle-management types cheating on their wives.

I seriously doubt that humans were holding on to each other for lifetimes before the dawn of religions. After all, the whole idea of staying together forever and ever is all taken from a few books that people wrote hundreds of years ago.
Let's say that we go 10,000 years back. Why would a man not screw around as much as possible? And if love existed, who's to say that it lasted for long periods? I remember reading an article that stated that "love" is a chemical reaction that lasts roughly six months, given or take a couple of months. I guess it's enough time to bond and mate.
Maybe this "monogamy gene" relates to something totally different, but has altered effects because of traditions that have grown with religions?

In our current society, monogamy makes more sense.
Until you see the hot little redhead that just moved in across the street from me. Then polygamy starts looking pretty damn good again.
Because which strategy works better would depend on what strategy everyone else in the local population is following. You end up with an stable equilibrium proportion where both strategies work equally well, all things being equal, but if you perturb it slightly the one becomes slightly more advantageous than the other and reproduces faster until the equilibrium is restored.
Does this mean we may be able to finally develop a cure for monogamy?
Will he/she buy that? Maybe there should be a cheater test kit. :)
Interesting question. The answer, though, is more interesting still: various flavors of "not necessarily".
The adaptive value of a trait can and does vary depending on its environment and the environment is different depending on how common the trait is. For traits having to do with deception, you tend to see some sort of equilibrium. Typically, a naive and honest population does better than a dishonest and suspicious one, because they don't waste resources on deception and deception detection. If, however, a lone cheater shows up in a naive and honest population, the cheater will do extraordinarily well. This will cause cheating to increase in frequency, and will create a selective pressure in favor of being able to detect cheaters. Sometimes, the cheaters tip the balance, and a naive and honest population becomes a suspicious and deceptive one, sometimes cheater detection is good enough to wipe out the cheaters, and often the two traits find an equilibrium point. The suspicion required to eliminate all cheaters will be too costly to be adaptive; but cheating will only work sometimes, and on a limited scale.
With the possible exception of simple deleterious mutations, traits are not absolutely better or worse, their value depends on their environment, and their environment depends in part on them. Just looking at the values of the traits at the beginning isn't good enough, you need to use a game theory approach, and look at the value of the traits across repeated rounds.
Being polygamous I wonder if I have this gene...hehe I know my wife her girlfriend, and my two other partners don't. ;)
-Ours is the wisdom of Solomon, the magic of Merlyn, the fall of Icaris.
One researcher found that the overwhelming contribution to the increased rate of divorce is the modern concept of marriage for love instead of position/wealth. The current divorce trend is simply the end result of a curve started in the years following the civil war.
So if these conservatives want to go back to an idyllic time with low divorce & happy families - I say bring back arranged marriages.
And the women, they're looking for a powerful man to knock them up, and a nice dedicated man to stick with her and raise a family.

I think you might be wrong there.
In a welfare/socialist society, polygamy and promiscuety make more (evolutionary) sense for men.
Which would you rather be: 1) the guy that sleeps around with lots of women and gets lots of kids, or 2) the guy that stays with a single woman and gets taxed to death to support all the single mothers, left over from the first guy.?
Obama likes poor people so much, he wants to make more of them.
Genetics is becoming the new astrology. Seriously. It's a good analogy too, sure stellar bodies affect our natural worlds, and sure genetics affects our bodies and minds, but I have not seen any proof that theses genetic changes are significant to human behavior on a day to day level.
Sure an animal living on instinct, slave to the chemicals sloshing around in it's brain pan, has it's mating style dictated by genes, but humans are just a little smarter then that.
I used to be a Beta male and used to pursue monogamy through out high school and early college for exactly the same reason you describe. Then I started working construction, got buff and learned how to quote "play the field" and have done things that belong on Tucker Max, not /., but I changed and I didn't need gene therapy to do it, why? because I think, and I can rationalize and weigh consequences against rewards, so while I may feel guilty for sleeping around, I know it's way funner than having to put up with some cow.
Humans are led by their frontal lobe and will ignore all those little subconsciouses chemicals in favor of what ever is easiest. I'm sure this gene might have an affect, but I'm sure on full blast the best difference it would make would be to cause a guy to buy his wife flowers after he cheats on her. Smoking a cig has a stronger kick.
The reason the gene is still around and hasn't gone one way or the other is because it's just genetic kruft that doesn't matter.
So is "Genetically Monogomous" going to be incorporated into eharmony profiles?

Marriage is the worst thing that can happen to you. Worse than a car accident, in most cases.
This is slashdot. Which means that a lot of those non-polys ain't mono, they're zippo.
You don't have to go 10,000 years back (as a previous poster stated) to see where this gene might be disadvantageous. Try a mere 120(ish). I read a artistic biography about Paul Gauguin in my Psychoanalytic Approach to Art class (it was one of those classes that I took just to call 'bulls$hit' but ended up learning something) and he described at great length the sexual practices of the people of Mataiea village.
Essentially, the people of the village were grouped into four "sections". You had:
Every night, a particular woman was selected (or several), and the able, fertile males - for lack of a better expression in a public forum - "had at her." All at once.
The idea behind this was that this would ensure that the woman would be impregnated after a time, and that the most fertile male sperm would "compete" for the egg, ensuring that it was the most fit to be born. Also, the men would never know which children were explicitly theirs - and the women would never know who the real father was - so the community as a whole would raise the child.
To (most) Western standards, this is pretty gross. To Gauguin, it was fascinating. However, you could see how a "monogamy gene" would not be advantageous in such a circumstance. The book - and Gauguin's writings - seemed to indicate that more 'sensitive' men , who may possess this gene, were thrown in the third group because they were not considered true "men". (Homosexuals were also in this group, for the record.)
Also, in closing, I'd like to point out that this society landed itself absolutely nowhere. Most successful empires/expansions of human civilization relied on monogamous culture - after all, you needed an heir to hand a crown to, and the wars between siblings were already bad enough without having to choose which *mother* produced the rightful heir. (Although, that happened regardless).
If I had one of those monogamy genes, I'd want to help it thrive - so I'd go find a bunch o' girls and get 'em pregnant...
Bow-ties are cool.
The poster didn't say anything about marriage. He just said "monogamous relationships."
"Living together in sin" qualifies as a monogamous relationship, and it very well may include frequent sex and home-cooked meals. In fact, remaining unmarried in such a relationship could be quite fulfilling for both partners while avoiding the marriage tax penalty and other legal complications.
Furthermore, each partner will feel free to leave should things turn sour (rather than trapped by a contract and economic devastation from an expensive divorce). This could cultivate a much healthier state of mind (while avoiding the "I don't have to work so hard to please you now, because we're married!" mentality) which will keep the couple together even longer than if they got married.
I am curious to know, however, why you think marriage is misery. Worse than a car accident? In what way? Is it because your spouse pulled a bait-and-switch on you, becoming someone entirely different once the contract was signed? Sounds to me like you just picked the wrong person....
Scientific study has now shown that people are likely gay from the time they're born due to differences in brain structure.
Science has discovered that Toxoplasmosis makes women more promiscuous and men more foolish.
Through statistical surveys we know that a vast number of people suffer from addiction, organic maladies, and depression.
Now through the science of genetics we are able to see a correlation suggesting why some humans may desire to be more liberal in the distribution of their DNA.
I find it amazing all the factors that go into making humans be who they are, to make and accept the choices they do, and how much of it is determined by prior conditions. As human nature is being illuminated by science, I find it deepens my appreciation of this human condition, to realize the aspects of our nature that we have to work with, and how one part of us can want to stay committed to one path but be struggling with other aspects of our nature that draw us elsewhere.
And so it also strikes me how much the imagination plays a part in outlining the whole human experience and determining whether we overcome our sometimes outmoded natural impulses.

Since it doesn't seem to be, that would seem to indicate that perhaps there is no evolutionary advantage to either side. With no advantage, there is no pressure for humanity to tend in one direction or the other. That could yield a pattern closer to what we are seeing now.
Or it could be that it's a mixed strategy equilibrium in which case it makes sense for a certain percentage of people to be monogamous and the rest not to be.
Would one non-monogamous guy be at an advantage in an otherwise monogamous society? Possibly -- he'd be able to father more children that way. Would one monogamous guy be at an advantage in an otherwise non-monogamous society? Possibly -- since everyone else doesn't really stick around to take care of their kids, his children would be better cared for and thus more likely to survive.
If those two statements are true, you'd expect some sort of mixed strategy equilibrium.
