Sexual diversity

The facts of biology plainly falsify the oft-repeated notion that homosexuality is unnatural. Every species has evolved its own sexual ecology, and so nature resists generalizations. Does humanity’s natural inheritance include homosexual bonds and behaviors? Certainly. This conclusion is reinforced by the growing evidence that our sexual orientation is influenced by both our genes and the environment that we experience in the womb.

A wide, living rainbow arcs across the natural world. Diversity rules in sexuality, just as it does in the rest of biology. This natural variety does not provide ready-made moral guidance. But to claim that the only natural forms of sex and pair bonding occur between unambiguous males and females is to ignore the facts of human biology. Let those who wish for marriage to be “founded in nature” take note: the view outside the Supreme Court is full of life’s beautiful sexual variegation.
