Not Clearly Pro or Con to the question "Is Sexual Orientation Determined at Birth?"
"Any human behavior as complex as sexual orientation is going to involve multiple contributing factors. What the recent work of Breedlove [...] and our work on [the auditory system] reveal is that there are in fact physiological concomitants to homosexuality. They represent confirmations of beliefs [...] that many people had for a long period of time [...] but you need the scientific documentation in order to move forward. Eventually the goal would be to identify those brain centers that seem to be responsible for sexual orientation."
