The study has no immediate implications for human sexuality.

But the researchers caution that controls on a fruitfly's sexual behaviour are undoubtedly different from our own. "In the case of humans, we know that our sexual behaviours are not irreversibly set by our genes," says Dickson. "But that doesn't mean the genes have no influence," he adds. "There's still a lot of mystery surrounding the causes of homosexuality," says Hans Van Gossum of the University of Antwerp, Belgium, who has studied fly mating patterns. "It's too early to draw strong conclusions on simple mechanisms like this."What I believe is happening here is more of the same stuff we see all the time. Certain news makes headlines but it really can't be tied into human homosexuality.

Putting gene X into another species and expecting to see a behavior is unrealistic--a 'flight' gene from Drosophila, if it existed, is not going to make a mouse fly," Dickson explains, noting that only members of the same species might be expected to share the same set of "normal" behaviors.
"So you need to put gene X in a normal animal of the same species that doesn't normally do Y. This is really only possible with sex-specific behaviors" like courtship, he says.
