To their surprise, neurobiologists have discovered that homosexuality can be turned on or off in fruit flies. They’d known that sexual orientation can be genetically programmed, but they didn’t realize it could also be altered by giving a drug that changes the way the flies’ sensory circuits react to pheromones.That's crazy wierd. I'm really uncomfortable with this for several reasons.
Within hours of the treatment, previously heterosexual male fruit flies would be courting other males, and treatment could also cause flies who had been engaging in homosexual behavior to become exclusively heterosexual, the neurobiologists report in Nature Neuroscience. You can read a summary of it here from the University of Illinois at Chicago, the home of one of the researchers, David Firestone.
Tierney lists some possible problems and issues it could raise.
So let the discussion begin. I don’t think of homosexuality or heterosexuality as an “illness” to be “cured,” but I wonder how people would use the ability to control sexual orientation — to have a designer libido. Would some people, gay or straight, who weren’t having luck attracting one gender decide to switch to the other? Would some people casually switch back and forth?
Would some social conservatives (like Leon Kass), who normally object to biologists “playing god” and pharmacologists altering “human nature,” change their minds and urge the use of biotechnology to promote heterosexuality? Would some social liberals try to restrict the use of this biotechnology? Would parents, gay or straight, want to regulate their children’s sexual orientation — and should they or their children be allowed to do so?
What do y'all think?
