The Evolutionary Mystique of Homosexuality
Reparative or conversion therapy is a method used to ‘fix’ homosexuality. Its premise is based entirely on one of two or both of the following notions: hetero-normative masculinity and heterosexuality as ‘the natural state’. In essence, that it is bad parenting that leads to homosexuality. Both of these notions, however, are socially constructed concepts and deeply grounded in the Abrahamic religions’ understanding of gender and sexuality. In other words, the premise is utterly unscientific and as vacuous as it is arbitrary.
But however you feel about this stance it implicitly poses one big question to the ‘nature’ side of the gay debate, ‘If it is genetic then how do gays exist if they fail to reproduce?’
Well, the short answer is we don’t know. The longer answer provides us with numerous workable theories which confirm what we’ve always thought which is that sexuality is a very complicated aspect of human biology.
Male Fertility (The Johnny Depp Effect)
It has long been understood that women prefer more feminine features in men, both behavioral and physical. Compassionate men with heavier lashes apparently give one an edge. So it is possible that in the right dose these genes confer a reproductive edge. If, however, too many of these genes are inherited then a man may end up too fabulous and boom, homosexuality.
Other studies suggest female relatives of gay men on the maternal side show signs of being more reproductive than female relatives of straight men, suggesting that a gene in the X chromosome of men confers heightened fertility in women. This increased fertility is thought to be connected to an increased attraction to men that can sometimes miss the mark in women and land in men, leading to same-sex attraction.
The Big Brother Effect
Studies show that with every boy a woman has she increases by a third the chances that her next son will be gay. No one really knows why this is but there are theories. The belief is that with every male a woman has her body increasingly develops an immune reaction to the proteins involved in developing the male brain, resulting in an altered sexuality and possibly more. Because said woman has presumably had children before this event who have gone on to reproduce themselves, this pre-natal mishap continues unabated.
Among identical twins, if one is gay there is a twenty percent chance the other twin will be too which, while high enough to not be random, isn’t as high as we might expect if homosexuality was strictly and simply genetic. The explanation here is that ‘epimarks’, what determines whether a gene is active or not, is not always inherited.
The shortest answer is that plenty of gay people do indeed have biological children (about 37%, 60% of which are biological) and that would be enough to do the trick.
In the end however, it seems sexuality is associated with a number of genetic and developmental factors that impact its outcome. It is even possible that more than one process is responsible. Though ultimately, whether it is genetic or not is irrelevant to the question of whether two consenting adults should be able to fuck.
