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."

Trust in a Bottle 658 comments
flosofl writes "The BBC has a report on oxytocin and its ability to skew our trust levels. 'The participants in the study played a game, in which they were split into "investors" and "trustees." The investors were then given credits and told they could chose whether to hand over zero, four, eight or 12 credits to their assigned trustee.' Some of the investors were given oxytocin via nasal spray. The results were surprising: 'Of 29 investors who were given oxytocin, 13 (45%) displayed "maximal trust" by choosing to invest highly, compared to six (21%) of the 29 investors who were given the dummy spray.' When the trustee was a computer, there was no difference between the two test groups."

Research Suggests Polygamous Men Live Longer 483 comments

After accounting for socioeconomic differences, men aged over 60 from 140 countries that practice polygamy to varying degrees lived on average 12% longer than men from 49 mostly monogamous nations."

Actually it's not a lie. Like everything, there are of course exceptions, so I'm sure some people do lie, but I get all of the above. And my wife is wonderful. I love being married. So yeah, if you wanna delude yourself out of the fun, go ahead... but consider the fact that you haven't tried being married, so how would you know the truth? Married men are inherently credible when talking about this issue, and unmarried men are without credibility, for the following reason: all us married men have been both single and married, and I personally can say that after trying both, marriage is far superior.
Sorry, but as a creature of reason and logic (which your appeal to science shows that you are), you are still without excuse. Anyone who claims reason has the tools necessary to rise above base animal instincts and live differently. Whether this alleged gene actually is proven to be true or not, the "serial non-commiters" still have no excuse to use the women around them.
As humans, we have to rise above this non-commitment, because regardless of a specific gene, societies in which commitments are made and upheld are inherently more stable and peaceful than those in which no one can trust anyone's word. As humans, our goal should be to form stable societies that are best for us, not to follow our genetic dispositions.

Or rather : in different circumstances monogamy may provide an evolutionary advantage. If you intend to wage unceasing war ("live off the land" (and the passersby)), for example, monogamy would be a bad idea, since lots of men will die, leaving behind women, even though some limit would be good (say you expect 50% of the men to be involved in war, then you should allow 2 women to one man, if you expect between 75 and 90% of your society to be dedicated to war, then 4 women to 1 man seems appropriate (and obviously only to men who can afford not to be on the frontlines, who should basically stay away from women, except the occasional rape of a succesful raid) (then again, in war, are limits like these really going to be respected ?). If you allow without limit (or allow polygamy + concubines) then clearly you expect to do nothing else than warfare, and marriage means nothing except for inheritance.
In peace, you'd need to prevent men remaining behind alone without partner (because for every extra woman one man has, another has to do without, 4 women to one man would become 75% of men without contact with women in extremis, realistically, say 50% of men, 4 women + unlimited (and exclusive) concubines would mean something like 999/1000 of men without partner, in some cultures that is normal, or was normal not too long ago), as that will certainly not be helpful in helping them build instead of destroying society, therefore in a peaceful setting, you'd want monogamy.
The fact that genes start expressing it is not very surprising. Polygamous cultures are known for being more than a little agressive, and genes are how humans adapt to their environment. If the environment or the culture changes to be less suitable for agriculture (or the culture doesn't know, or incorrectly conducts agriculture, e.g. predatory agriculture, or not doing anything about overpopulation, or ...) the genes will adapt to become less monogamous.
If raiding is basically impossible, for whatever reason, building things will become important, and monogamous relationships become an evolutionary advantage. Certainly after 10 generations the effects will be very noticeable.
Since this gene will very much influence how agressive people are against "other tribes", it is one of the prime parameters that will determine the layout of the resulting society, and may introduce all sorts of limits (e.g. agressive societies will never have any population density for obvious reasons, which can easily translate in a very low maximum population limit)

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

Lots of reasons...
Inability to find good mates... Ideal mothers for your children would reject you knowing that you wouldn't provide for them?
Low chance of offspring surviving... mothers would be unable to care for your children, and unable to find mates willing help them?
Societal acceptance... e.g. The other men would stone him? Stone the women he cheated with? Stone his offspring?
Monogamy exists in nature. There are reasons for why it works where it exists.
And if love existed, who's to say that it lasted for long periods?
Indeed. Monogamy isn't necessarily 'till death to we part' in modern society at least it simply means not cheating on your partner. It is entirely possible to marry, raise a child, separate, marry someone else, and even raise another child, all within the confines of monogamy.
Hell when I was a teen, most of us were pretty monogamous; its not that we all married our first crush, but rather that our teen years were a succession of monogamous relationships of varying lengths, some quite brief, and punctuated with periods of being 'single'.
And yes some people who were supposedly 'in a relationship' cheated, and when caught it carried a stigma, one that I would say definitely impacted their dating prospects in the circles where it was known that they cheated (applied to both males and females).

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.

Re:Hhhmm, (Score:5, Informative)
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.

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.

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.
