I know, there probably is no interest since we are a bunch if prehistoric science-haters. 

A twin study followed over twenty years shows that identical twins (%100 same DNA) should have identical sexual attraction, they don't, in fact it is 14% for females, less for males.  Even more interesting and telling is that as people age, those who once self identified as homosexual, now identity as heterosexual. 
Very interesting study, definitely worth the few minutes to read it.

Good find.
Why is it though, we actually have to prove something, that people already knew?
Queer, is just that, an abnormal behavior that develops over time.

If someone claims to have a genetic predisposition to steal, or rape, or murder, it doesn't justify the action. Not all "feelings" should be acted upon.
