Recent polls have shown that most Americans believe that homosexuals are “born that way” rather than become gay as the result of environmental factors. In fact, perpetuating the belief that sexual orientation is innate has been crucial to the gay rights movement. According to the most recent Gallup Poll on the subject, 88 percent of people who believe homosexuals are “born that way” support the legality of same-sex marriage, while only 39 percent of those who believe homosexuality is the result of environmental factors support the legality of same-sex marriage.
So, what happens when science proves that homosexuals aren’t “born that way”? Perhaps we’ll find out. A new comprehensive scientific study of the biological roots of sexual orientation released Thursday proved that there no “gay gene” and that genetic factors are insignificant in determining sexual orientation.
The research, which analyzed data on DNA and sexual experiences from almost half a million people, found there are thousands of genetic variants linked to same-sex sexual behavior, most with very small effects. . .
“We scanned the entire human genome and found a handful – five to be precise – of locations that are clearly associated with whether a person reports in engaging in same-sex sexual behavior,” said Andrea Ganna, a biologist at the Institute of Molecular Medicine in Finland who co-led the research.
According to Ganna, these genetic variances have “a very small effect” on sexual behavior, and combined, only explain “considerably less than 1% of the variance in the self-reported same-sex sexual behavior.” This means that non-genetic factors, including environment, upbringing, personality, and nurture “are far more significant in influencing a person’s choice of sexual partner, just as with most other personality, behavioral and physical human traits,” according to the researchers.
