Want to know if you are gay?
In other news: I was trolling their site and found [this] very interesting article. It states that a new study has found that the odds of a man being gay are increased based on the number of biological brothers he has. It doesn't matter if the brothers grew up with the man or not, just the fact that the mother gave birth to other boys does the trick.
The article didn't mention why this would be the case, or potential benefits species-wise, but states that the mother may produced certain antibodies that causes a subsequent male child to be gay.
I have a theory, one of population control. Maybe homosexuality is nature’s way of making sure a species doesn't propagate too much. After producing a certain number of boys (walking inseminators) a woman's body produces antibodies that influence her next boy to be gay. Thereby helping to ensure he won't go out and create more humans.
I love the idea. Though, of course, there are plenty of gay men who are only children or don't have any brothers (why is everyone looking at me?) but I think the theory holds in general, and the study speaks for itself.
That is, until it's proven incorrect.
