    "...found that mothers and maternal aunts of gay men tend to have significantly more offspring than the maternal relatives of straight men. The results show strong support for the "balancing selection hypothesis," which is fast becoming the accepted theory of the genetic basis of male homosexuality.

    The theory holds that the same genetic factors that induce gayness in males also promote fecundity (high reproductive success) in those males' female maternal relatives. Through this trade-off, the maternal relatives' "gay man genes," though they aren't expressed as such, tend to get passed to future generations in spite of their tendency to make their male inheritors gay.

    While no one knows which genes, exactly, these might be, at least one of them appears to be located on the X chromosome, according to genetic modeling by Camperio Ciani and his colleagues. Males inherit only one X chromosome — the one from their mother — and if it includes the gene that promotes gayness in males and fecundity in females, he is likely to be gay while his mom and her female relatives are likely to have lots of kids. If a daughter inherits that same X-linked gene, she herself may not be gay, but she can pass it on to her sons."

    Evolution? Work of the devil.
    Being gay helping evolution? More work of the devil. icon_twisted.gif

    YES.... very fascinating study.... but may work only in a percentage of the population, as most family have straight and gay sons at the same time... But a great study.

    Why are gay guys always looking for science to justify their existence? Just a question I've always had. Science is cool, but any scientific fact can be used for you or against you. What if scientists do discover that gayness is genetic, do you understand the full implications of such a finding? Fix the gene.

    I'm gay because I am.

    I'm also Jewish because I am.

    I need not another study to tell me why I am the way I am.

    In the end, it doesn't matter. We are what we are, and people that can't accept it can shove it hard up where the sun don't shine.

    Ultimately, the studies don't help persuade true bigots. They twist and filter everything to suit their world view.

    Hmm interesting. Since its on the X chromosome it could also attribute why females are more open to being bi and such and able to have "phases" while guys are not nearly as able too.

    I just read this...and came here...and bam, there's a thread. It's important because one of these days we'll be able to rationally prove without a doubt homosexually is natural and hopefully some kid will not blame the devil or feel he's sinned or whatnot for his homosexuality. I think THAT is the importance of this study.. to explain this to the point it can no longer be used as a weapon against us.

    However on the flipside.. lets say we were able to prove god didn't exist and homosexuality was natural and there is absolutely no heaven or hell, and when you die you just die. Would that drastically stop people from killing themselves and others because of belief in those things? eh..not really.. at least not immediately.

    Some people still believe we never walked on the moon... they do not believe in evolution and still believe our earth is only 10,000 years old..

    I'm all for science and logic though. In the end, what can be proven will dominate progress... meaning in the future.. like we have done in the past..we will take this knowledge and it's truth will produce something physical.

    I saw this study a few years ago. I find it fascinating. Viewing homosexuality through a scientific viewpoint instead of the religious one that I had been bought up to believe helped me come to terms with my homosexuality. It wasn't a choice I made, and it wasn't something that was done to me as a result of my upbringing.

    Having a scientific understanding of homosexuality is also important in the fight for gay rights. If scientists can prove that homosexuality is a naturally occurring biological trait, then the law cannot be biased against homosexuals anymore than it can be against those of different skin color, eye color, etc. It could be a huge game changer if the cause of homosexuality were found.

    It does not matter.. it's a catch22 because knowledge is definitely power..and with knowledge you get a double edge sword that will indeed work for you or against you, depending on where you stand and your vantage point. However if you deny knowledge, you blocking absolutely any and eveything that can result from finding whatever it is out. Even the unforseen consequences. Based on principle, everything should be explored.

    interesting observation... but phases are much more of an epigenetics thing - it's cultural... According to a recent twin studies:..."....confirm earlier findings that identical twins are more concordant for same-sex behaviors than fraternal twins are but only modestly so: In men, genetic effects appeared to explain 34% to 39% of the differences between the two twin groups (identical and fraternal twins), whereas in women, genetics accounted for only about 18% to 19% of the difference--a finding consistent with other research showing that sexual orientation in women is not as rigidly determined as it is in men...."

    ...men in the USA are not allowed to show much affections.... where straight guys in Turkey, Malay, Thai, Vietnam, and other countries can hold hand and lean on shoulders in public.

    A few years back Dawkins had speculated similarly (4:40) "it doesn't always have to be a gene for that thing...genes are not that deterministic"

    According to a recent identical twins study, gayness is partially genetic, and partially epigenetics (environmental mostly). This complicate things quite a bit and make understanding gayness not just basic 'hard' science, but social science as well (psychological factors).

    "The theory holds that the same genetic factors that induce gayness in males also promote fecundity (high reproductive success)"

    That just means they've the capacity for "high reproductive success" not that they've employed it.

    "Environmental factors" in this case could mean anything from hormone levels in the womb to diet during the early years of development. Psychological factors seem to be the least likelly influence at this point, as far as sexual orientation. I tend to think that psychological factors determine more about the types of people we are attracted to (butch, fem, tall, short, etc.) rather than the gender(s).

    Also, just because someone carries the gene for a certain trait doesn't not always mean that the gene is turned on. Hypothetically, most or all men could possess the "gay gene," but maybe it's only activated in certain circumstances.

    Taking the accuracy of the study for granted...

    That's an odd way of expressing the results of the study, as it seems to reverse cause and effect.

    It doesn't prove that there is a ``gay gene'' that increases fecundity. It seems rather to state something obvious: women with higher fecundity produce more offspring, and with a bigger ``pool'' of kids, you're more likely to find a gay kid in there somewhere.

    That would be interesting. I wonder, though, if there really is a cause of homosexuality, or if sexuality just is. Afterall, it would be an odd question to ask, ``what is the cause of heterosexuality?'' It's taken for granted as something that just is. Looking for a cause of homosexuality seems to suggest that homosexuality is an aberration. Kind of interesting.



    Not criticizing you, so don't take it personally; just thinking ``out loud.''

    Couldn't have said it better myself. Why wouldn't I want to know why, biologically, I don't want to breed with a women?

    yes and yes, ... but psychology is a chicken/egg situation with the biology environment, i.e. drugs/alcohol, or stimulating foods affecting psychology... it will be very interesting in the next couple of years to see what science will find out.

    Biologically, homosexuality definitely is an aberration.A (purely) homosexual person does not reproduce, and hence any genetic tendency to be homosexual cannot be passed on.

    From a purely scientific perspective, it is fascinating that a trait that is so detrimental to reproduction would be carried on for as long as humans existed. Fascinating as in "I am going to get a Nobel Prize if I figure this out," which explains the amount of research.

    The moral question, whether homosexuality is morally good or bad, in independent of the scientific question. Fortunately, we already know that homosexuality is morally neutral.
