Is There a "Gay Gene"?
Many laymen now believe that homosexuality is part of who a person really is * from the moment of conception.
The "genetic and unchangeable" theory has been actively promoted by gay activists and the popular media. Is homosexuality really an inborn and normal variant of human nature?
No. There is no evidence that shows that homosexuality is simply "genetic." And none of the research claims there is. Only the press and certain researchers do, when speaking in sound bites to the public.
How The Public Was Misled
In July of 1993, the prestigious research journal Science published a study by Dean Hamer which claims that there might be a gene for homosexuality. Research seemed to be on the verge of proving that homosexuality is innate, genetic and therefore unchangeablea normal variant of human nature.
Soon afterward, National Public Radio trumpeted those findings. Newsweek ran the cover story, "Gay Gene?" The Wall Street Journal announced, "Research Points Toward a Gay Gene...Normal Variation."
Of course, certain necessary qualifiers were added within those news stories. But only an expert knew what those qualifiers meant. The vast majority of readers were urged to believe that homosexuals had been proven to be "born that way."
In order to grasp what is really going on, one needs to understand some littleknown facts about behavioral genetics.
Gene Linkage Studies
Dean Hamer and his colleagues had performed a common type of behavioral genetics investigation called the "linkage study." Researchers identify a behavioral trait that runs in a family, and then:
a) look for a chromosomal variant in the genetic material of that family, and
b) determine whether that variant is more frequent in family members who share the particular trait.
To the layman, the "correlation" of a genetic structure with a behavioral trait means that trait "is genetic"-in other words, inherited.
In fact, it means absolutely nothing of the sort, and it should be emphasized that there is virtually no human trait without innumerable such correlations.
Scientists Know the Truth about "Gay Gene" Research
But before we consider the specifics, here is what serious scientists think about recent genetics-of-behavior research. From Science, 1994:
Time and time again, scientists have claimed that particular genes or chromosomal regions are associated with behavioral traits, only to withdraw their findings when they were not replicated. "Unfortunately," says Yale's [Dr. Joel] Gelernter, "it's hard to come up with many" findings linking specific genes to complex human behaviors that have been replicated. "...All were announced with great fanfare; all were greeted unskeptically in the popular press; all are now in disrepute."{1}
