The spectacular advances in research on the human genome, coupled with recent studies on the effects of hormones on behavior, upsets conventional viewpoints on our sexual behaviors, and control of them by our brain. Science has discovered quite recently that biological factors are themselves influenced by the environment, and individual history. This is new and fundamental scientific data.
This document brings new light on the diversity of sexual behaviors, which are not specifically human, since some 450 animal species have been identified as being at least partially bisexual.
Homosexuality is not the mental illness of yesterday, nor the genetic defect of tomorrow; it is simply a natural variant of one of our basic biological characteristics, our sexual orientation.
