The Evolutionary Advantage of Homosexuality

SaintRichie23

You know what's one thing that bothers me? People who say that homosexuality has no evolutionary advantage. Am I gay? Nope. Should I care? Probably not, but I'm sure those of same sex behavior (SSB) and other genders do. So here's to you guys! Fingers crossed that a shitstorm is not produced from this.


The Evolutionary Advantage of Homosexuality


The line of reasoning that SSB is a disadvantage to humans is the obvious fact that SSB partners cannot reproduce on their own, therefore they can't take a piss in the oh-so-wonderful gene pool that is the human species. It makes sense, granted, and some people counter it as a solution to overpopulation, but there is more to it than that.


1. Gay Tendencies Have Existed Long Before Humans Thought It Was Cool


Scientists have identified over 1,500 species that display homosexual tendencies. Lions, dolphins, chimpanzees, apes, flies, crabs, worms, I could keep going. Wanna know why? Because scientists are still going themselves. Their approach isn't, "Which species show homosexual behaviors," but "Can we find a species that doesn't have SSB behavior?" It's that common.

These animals have been around much longer than us, having more time to evolve and flush out unwanted traits and alleles. Why not get rid of the one trait that causes one specimen in a community to be evolutionary "useless" compared to the heterosexual ones? Its because there is an advantage to it, as it is persistent in so many gene pools of hundreds of different species (and counting).


2. Its in the Genes, Not the Mind


The Evolutionary Advantage of Homosexuality


The basics of genetics is this: most genes have several different alleles, which can be dominant or recessive to other genes, but each person has only two alleles of any given gene (50/50 from mom and dad). For instance, for the gene that determines eye color, there is a slew of various alleles that determine just that. If a particular allele is present, it could take priority over the other one and vice versa. Cool. Now, some genes are affected by other genes, so if a particular gene has a certain allele, there is a pretty fair chance that a linked gene will also have a certain allele. For example, there is a link between your finger lengths and your gender. They are not related in an obvious sense, but they are linked to one another due to more genetic magic that I rather not bore you with. Straight males, for example, tend to have longer ring fingers than index fingers, while gay males tend to have both of the same length. The opposite trend is found in women. In summary, one gene can have affects on other genes.


Recently, studies have been conducted on fruit flies. Surprisingly, the common fruit fly have many genetic similarities to humans, and genes we identified on them have actually been found to be homologous (similar) to human genes. Anyway, male fruit flies that showed homosexual tendencies tend to have female relatives that were more fruitful (pun intended), and the genes associated with this behabior were passed down the paternal specimens (the Papa Smurfs). Is this relevant? (Source)


3. You Bet Your Rosy Butt Cheeks They Are!


Andrea Camperio-Ciani from the University of Padova found that gay human males had female relatives who were more fertile and who also had more children (Source). Additionally, in societies and communities where said community is small and tight-knit, gay people are actually given a high status and role. If you're a gay man in Samoa, you are considered a "helper of the nest" and you help your mom and sisters out with caring for their children (Source). This is an example of a theory that is being thrown around the scientific community on whether animals will risk their life for the better survival of others. This theory is known as kin selection, but it needs more time to develop and receive more data and research, and its a topic of some debate.


4. Genetics is Still Pretty Complicated Though...


You may have noticed I have done a lot of talking about explaining the advantage of gay male behavior, but not of female behavior. This is where some scientists begin to scratch their heads. Studying these behaviors in men is a lot simpler and easier to do, but women tend to display what is considered "erotic fluidity." Where men's sexuality is pretty reliant on their genes, women are more sensitive to environmental influences. Lisa Diamond from the University of Utah found that women's sexual orientation seems to be molded more by positive/negative experiences, cultural influences, and intensified feelings of affection/love (Source). Well... is it still genetics, or can a girl be flip-flopped on their sexuality based like an indecisive middle-aged man at Taco Bell?


5. Still Boils Down to Genetics


Despite Dr. Diamond's studies, other studies show a pretty heavy reliance on genetics. You just need to study some twins.


The Evolutionary Advantage of Homosexuality


Identical twins are 100% identical, hence the adjective "identical." A 2011 study found that, in women, if one twin was a lesbian, the other one was too as well. This shows that there is a genetic relationship between your genome and your sexuality, although said sexuality can be reshaped by your environment and life experiences. Dr. Alan Sanders did the same thing with male twins, finding similar results and also narrowing down the location of the gay gene to chromosome and/or the X chromosome (Source).


In Conclusion...


TL;DR: gay people are not just around to prevent overpopulation. The genetics behind it allow their relatives to be more fertile and reproductively successful. There is still a lot of research that needs to be done to find more advantages as well as the location of the "gay" gene as there hasn't been too many extensive studies on the topic thus far (talking about most studies being about 10 years or so). Homosexuality is here to stay, and it helps us all at the end of the day. So go on and love one another in the way you and your partner(s) see fit!


One Last Point:


The Evolutionary Advantage of Homosexuality


It is an evolutionary advantage for Neil Patrick Harris to be gay, as there wouldn't be any women left for the rest of guys on Earth. Any questions?
