That experiment sounds fine and all, but nowhere in my link did any scientist try to correlate sexual identity with IQ.
In fact, IQ is entirely subjective.
That is all.
Call me bigoted but I believe you forego the right to bear children when you prefer the same-sex....

but if they have offspring then they aren`t homosexual, they are bi-sexual fruit flies.

Some people believe that homosexuality in nature is a way for a species to curb it's overpopulation.
Yuppa just said that 5 posts up. And not to put too fine a point on it, but if that's the strategy, it didn't work.
"Scientists" publish garbage like this and then expect us to take them seriously? How can organisms who do not reproduce--by definition, if homosexual--have an evolutionary advantage?

It defies common sense, and is so obviously politically motivated.
Idiocy like this makes my eyes glaze over and roll back in my head until they start bleeding.
Total, 100%, grade-A, unadulterated bulls#.
IQ test and its correlatives like the ACT/SAT and PISA scores have real predictive powers.
They are measuring something.
At aggregate/population levels it can correlate with a ridiculous amount of things. Unemployment, Divorce rates, income, etc.
At country level average IQ can predict crime rates, corruption, number of scientist, life expectancy, level of democracy, poverty. 97 is considered the minimum average IQ for a modern society. Below 90 and democracy falls apart
Scientists have found even more evidence that sexual orientation is largely determined by genetics, not choice. That can undermine a major argument against the LBGT community that claims that these people are choosing to live "unnaturally."
That's at least according to a new and groundbreaking study recently published in the journal Psychological Medicine, which details how a study of more than 800 gay participants shared notable patterns in two regions of the human genome - one on the X chromosome and one on chromosome 8.
While many previous studies have looked into potential genetic drivers of homosexuality, these studies often boasted a significantly smaller sample size or lacked common controls. This is the first study of its kind to boast such a robust sample size and also be published in a scientific peer-reviewed paper.
On Thursday, UCLA molecular biologist Tuck C. Ngun reported that in studying the genetic material of 47 pairs of identical male twins, he has identified "epigenetic marks" in nine areas of the human genome that are strongly linked to male homosexuality.
In individuals, said Ngun, the presence of these distinct molecular marks can predict homosexuality with an accuracy of close to 70%.
Historians of homosexuality will judge much twentieth-century "science" harshly when they come to reflect on the prejudice, myth, and downright dishonesty that litter modern academic research on sexuality.
Shang-Ding Zhang and Ward F. Odenwald found that what they took to be homosexual behavior among male fruit flies--touching male partners with forelegs, licking their genitalia, and curling their bodies to allow genital contact--could be induced by techniques that abnormally activated a gene called w (for "white," so called because of its effect on eye color). Widespread activation (or "expression") of the white gene in Drosophila produced male-to-male rituals that took place in chains or circles of five or more flies. If female fruit flies lurked nearby, male flies would only rarely be tempted away from their male companions. These findings, which have apparently been reproduced by others, have led the investigators to conclude that "w misexpression has a profound effect on male sexual behavior."
Indeed, over the past 2 decades, researchers have turned up considerable evidence that homosexuality isn't a lifestyle choice, but is rooted in a person's biology and at least in part determined by genetics. Yet actual “gay genes” have been elusive.
A new study of male twins, scheduled for presentation at the annual meeting of the American Society of Human Genetics (ASHG) in Baltimore, Maryland, today, could help explain that paradox. It finds that epigenetic effects, chemical modifications of the human genome that alter gene activity without changing the DNA sequence, may have a major influence on sexual orientation.
Researchers thought they were hot on the trail of “gay genes” in 1993, when a team led by geneticist Dean Hamer of the National Cancer Institute reported in Science that one or more genes for homosexuality had to reside on Xq28, a large region on the X chromosome. The discovery generated worldwide headlines, but some teams were unable to replicate the findings and the actual genes have not been found—not even by a team that vindicated Hamer's identification of Xq28 in a sample size 10 times larger than his last year. Twin studies suggested, moreover, that gene sequences can't be the full explanation. For example, the identical twin of a gay man, despite having the same genome, only has a 20% to 50% chance of being gay himself.
