A key part of the argument against homoerotic relationships, fundamental to the Catholic Magisterium, to the religious opposition more generally, and to the supporters of so-called “traditional” marriage, is that same sex relationships are somehow “unnatural”, “against natural law”. This claim is entirely without foundation. What these groups have in common, apart from their conclusion, is a total disregard for the evidence. Some research into the Laysan albatross neatly illustrates this. The disregard of the need for evidence does not only apply to claims for natural law: exactly the same charge can be made against Vatican claims that “homosexuals” are motivated solely by -indulgence, and that homosexual “acts” lead one away from God – claims that likewise do not stand up to scrutiny. For now, though, I am concerned only about the problem as it applies to the argument from natural law
All albatrosses are large birds nesting in isolated colonies free from natural predators, which makes them easy to study (the birds are trusting and allow researchers to get up real close and personal). Much of their behaviour is well-known. For instance, in one colony at Kaena Point, Hawaii, there are about 120 breeding pairs, who gather for mating every November. They form long-term partnerships, and after copulation, lay a single egg, which they incubate in shifts, taking turns to leave the nests for weeks at a time to feed at sea. They form long-lasting, often life- long pairs, and were praised by former US first lady Laura Bush for their commitment to each other, and the example they offered as icons of monogamy. The obvious assumption that these monogamous pairs represent one male and one female in a neat nuclear family, though, turns out to be false. One third of the pairs are female couples, some of whom had nested together every year since right back to the start of data collection – 19 years.
Ornithologist Lindsay C Young has been studying this albatross colony since 2003, as part of her doctoral dissertation. She says that the discovery of so many female pairs forced her to question assumptions she didn’t even know she was making. This in itself was something of a breakthrough: observations of same sex behaviour or relationships in the animal world are not new, but too often in the past, biologists have simply ignored them, or attempted to explain these observations as aberrations.
Joan Roughgarden quotes one notable scholar who claimed in 2000, at the end of a long and distinguished career, that “When animals have access to members of the the opposite sex, homosexuality is virtually unknown in nature, with some rare exceptions in primates”.
But just the previous year, Bruce Bagemihl had published a book reviewing published academic research into over three hundred vertebrate species which engage in same-sex courtship and genital contact. In some of these, homosexual activity is even more frequent than heterosexual intercourse.[ad#In post banner] Read the rest of this entry »
