that gay men and straight women share similar traits—most notably in the size of their brains and the activity of the amygdala—an area of the brain tied to emotion, anxiety and aggression. The same is true for heterosexual men and lesbians.
This is not the first such study to intimate that homosexuality has a biological basis.
Personally, I believe such a basis will be confirmed as more studies are performed. Unfortunately, since the subject is such a political third rail in US politics, the real research shall continue to be performed abroad when it is undertaken at all.
