Why do gays exist?

GAY studies have gathered some pretty interesting theories as to how/why homos exist. A lot of it is considered to be genetic but it’s definitely not considered as simple as a ‘gay’ gene. In the same way you wouldn’t have a ‘tall’ gene. It’s likely to consist of a variation of different aspects, including habitual and social. For example, Boys who have older brothers are significantly more likely to turn out gay, and apparently for every extra boy child, this chance raises by about another third. This could either or both be due to some kind of social big brother effect, and/or a hormonal effect within the mother, in which various proteins or immune reactions are affected after a first time male birth. Could be anything really.

The problem is that it doesn’t make evolutionary sense. Even if it is beneficial in some way in a Darwinian viewpoint, if those who are gay do not breed, it stands to reason that the gay part of the tree would fade out with those who die without passing on their information. So it seems logical to assume it’s NOT genetic, and it’s just something else.

However, my favourite theory so far in terms of genetic possibility is roughly this (of which has quite a bit of evidence backing it up but by no means declared proof): Groups of genes called alleles have beneficial effects in reproduction. When passed down to a woman, it affects her and gives off a positive sense of attraction towards men. The more of this one has, the more attracted they would become. But if this allele is passed on to a male born, it can create a same-sex preference, since it is passing on the same stuff to an opposite sex. If the success rate of this is great enough in the women, there is no reason for it to fade out of the genetic pool, whilst still occasionally passing down to men as the generations go by. Something that has a double purpose, basically. This happens a lot in nature which is why Intelligent Design is basically bulls**t.

The evidence to back this up comes from Italy, where they found female relatives of gays had more children than those related to straight men, implying that the allele is more present and affecting in the gay man’s family.

The bottom line is, it really doesn’t matter. But it’s interesting, and it’s science’s job to figure out the things we don’t know, no matter what those things might be.
