When an article about "fruit flies" popped up on a gay website,
at first I thought it was about straight women who gravitate toward
gay men. (The other, uglier term for such women is "fag hag.")
Alas, the article was referring to actual insects, the annoying
little ones that remind you to throw away overripe bananas.
Apparently, some researchers at Penn State University have
discovered that by getting groups of male flies "drunk" with
alcohol fumes, they can induce homosexual behavior. (Just like frat
boys.) They observed this behavior in a small transparent chamber,
which they called-I am not making this up-a "Flypub."
According to newscientist.com,
"The first time they were exposed to alcohol, groups of male
flies became noticeably intoxicated but kept themselves to
themselves. But with repeated doses of alcohol on successive days,
homosexual courtship became common. From the third day onwards, the
flies were forming 'courtship chains' of amorous males."
Yes. And by the fourth day, they were redecorating the Flypub in
sleek mid-century modern furniture. By the fifth day, they were
serving Cosmopolitans and debating the relative fabulousness of
Martha Stewart's new Wedgwood line at Macy's. And so on.
The article continues,
"[Lead researcher Kyung-An Han] argues that the drunken flies
provide a good model to explore how alcohol affects human sexual
behaviour. While the ability of alcohol to loosen human inhibitions
is well known, it is difficult for scientists to study."
Of course it is. Imagine the grant application:
"Describe the proposed methodology."
"Um, well, I'm going to get a bunch of college students drunk
and naked, then record their behavior."
Sounds like a shoo-in for funding, no?
It's not that I doubt the merits of such research. Granted, I'm
far more interested in figuring out how to keep fruit flies out of
my kitchen than how to make them horny. Still, I appreciate the
value of scientific inquiry-all else being equal, the more we know
about the world, the better.
My problem arises when people start using these studies to draw
conclusions about human romantic behavior. While Han has warned
against being too quick with such inferences, other researchers and
commentators have not been so cautious.
For example, when Austrian researchers in 2005 genetically
manipulated a female fruit fly to induce homosexual behavior, Dr.
Michael Weiss, chairman of the department of biochemistry at Case
Western Reserve University, told the International Herald
Tribune, "Hopefully this will take the discussion about
[human] sexual preferences out of the realm of morality and put it
in the realm of science."
I hope it does no such thing. For two reasons: first, because
human sexuality is far richer and more complex than fruit-fly
mounting behavior. (Fruit flies don't pout if you don't call the
next day-or so I'm told.)
Second, and more generally, because science and morality tell us
different things. Science tells us something about why we behave as
we do. It does not tell us how we SHOULD behave, which is the
domain of morality. Science cannot replace morality or
vice-versa.
To put the point another way: while scientific study can reveal
the biological origin of our feelings and behaviors, it can't tell
us what we should do with them. Should we embrace them? Tolerate
them? Change them? Those are moral questions, and simply observing
fruit flies-or humans, for that matter-is insufficient to answering
them.
But can't these studies prove that homosexual attraction is
"natural"? Not in any useful sense. Specifically, not in any sense
that would distinguish good feelings and behaviors from bad ones.
Discovering the biological origin of a trait is different from
discovering its value.
Beyond conflating morality with science, popular commentators on
these studies have an unfortunate tendency toward
oversimplification.
Consider last year's fruit-fly study at the University of
Illinois, which the gay newsmagazine The Advocate
announced with the headline, "Study finds gay gene in fruit
flies."
Except that it didn't. What the study found was a genetic
mutation in fruit flies that rendered them essentially bisexual.
Scientists could then switch the flies' behavior between
heterosexuality and homosexuality through the use of
synapse-altering drugs.
In other words, the study neither found a "gay gene" in fruit
flies nor answered any questions about how hardwired or malleable
human sexual orientation might be.
Meanwhile, one fruit fly who participated in the Penn State
study released the following statement: "Dude, I was so drunk that
day-I don't know what happened!"
