Study finds brain difference in gay rams

Researchers at Oregon State University have announced another finding linking sexual orientation to biology, as opposed to learned behavior.
The scientists recently discovered biological differences between the brains of homosexual rams and heterosexual ones, and the news will likely contribute to the "nature vs. nurture" debate over homosexuality's origin in humans.

Wanting to ensure breeders could purchase heterosexual rams, researchers began a study in the hopes of determining the animal's sexual orientation. They received grants from the National Institutes of Health: one for about $800,000 in 2001; a second for $2 million in 2004, according to the Associated Press.

Fred Stormshak, distinguished professor of animal science at Oregon State, and one of the researchers in the project, told the PlanetOut Network on Monday that his team found striking differences in the brains and hormones of certain rams.
