Despite recent game-changing strides in the movement for gay equality, the world is still far from perfect when it comes to LGBT rights. Many still believe that sexuality is simply a lifestyle choice, and that sexual orientation can be "reversed" if the right steps are taken. But a new study published in the journal Psychological Medicine may be the strongest evidence yet that baby, you're born this way.
The study, the largest study of genetics and homosexuality ever conducted, examined 409 sets of gay brothers over the course of five years, using blood and saliva to analyze their genetic makeup.
The results link male homosexuality with two regions of the human genome: a portion of chromosome 8 and a portion of the X chromosome. According to the study, these regions had previously been deemed significant by other researchers looking for similar patterns.
Dr. Alan Sanders, the study's lead author, told the AP that the study "is not proof, but it's a pretty good indication" that a specific genetic makeup on the X and eighth chromosome influences sexual orientation. "It erodes the notion that sexual orientation is a choice," said Sanders, who studies behavioral genetics at NorthShore University HealthSystem Research Institute.
