I don't know what that is or where it comes from. Had this still been a page one topic I`d Google it to find out, but this is now page 4 and I`m moving on.
The fruit fly study I was talk about was the cover story of the science journal Cell. The title was Genetic and Neural Control of Drosophila Sexual Behavior. The fruit fly study isn`t too useful since it is fruit flies and not humans, but it does show a pattern of evidence that is quickly becoming undeniable. There are environmental factors after birth that affect orientation, but there is also evidence that some have their orientation set before birth.
In Nature there are no hard an fast rules. I`d be willing to bet that some people do choose to be gay, but the evidence is mounting that the majority of people do not choose their orientation. There is good evidence that that orientation is set in utero.
1) Without a wink or a chuckle, Odenwald claims that these male fruit flies are gay -- and that he and Zhang made them that way. The scientists say they transplanted a single gene into the flies that caused them to display homosexual behavior. And that's very interesting, they assert, because a related gene exists in human beings, although there is no evidence yet that the human gene has an effect on sexual preference.
2) The research demonstrates a likely link between brain function and sexual orientation, Savic suggests. But she told New Scientist that the study "does not answer the cause-and-effect question"
So the brain-activation of gay men by AND may contribute to sexual orientation of those men, or simply be the result of their orientation and sexual behaviour.
Those the studies you were referring to? You left those parts out, but interesting none the less.
