The Logical, Evolutionary Reason for Being Gay

I recently read an article in one of those new fangled online science websites that concluded that there is a higher prevalence of homosexuality when the measured individual has an elder sibling. What an interesting thing to show in numbers (because we all know everything is a giant math equation….).

 

This, in my head, entirely ends the argument. I have always tossed back and forth in my head, in my Darwinistic mentality, how we can choose against a certain trait, as not being attracted to the sex that has the ability to pass on you genes would definitely, over the long run, affect the viability of your genetics and yet still have a strong homosexual population. Well…lets break it down a little farther first.

 

We are all chemistry sets. We are put together inside of our mothers womb as a result of an amazing interaction (sperm meet egg). From this point on we are molded, uniquely EVERY single time – even perfectly matching twins have some differences (life doesn’t stop growing and molding at birth...) from an amazing concoction of chemicals and events and whatever else affects us. All of these things help write our programming, software, whatever it is you wish to use to define us as and from these we become.

 

So, as we are being splashed with testosterone and estrogen we are also taking cues from our mothers body which, in a genetic sense somewhere, already knows that she has had off-spring. From an overall evolutionary standpoint, the purpose of moving forward does not necessarily mean any particular individual in that society moves forward, but that the general genetic line does. What that means, is that it may be advantageous for an individual to be homosexual in a family because there is an elder sibling whose job it is to bear children.

 

So we get an amazing example of a genetic trait slipping under the radar of needing to be passed on as a reproductive trait because it is prevalent enough that it only needs to be activated when a very certain set of situations come up. Now every one will say explain why there are gay people with no siblings…easy answer…because the genetic trait is there and it comes through sometimes as a reaction to nature, it still has the possibility of coming through when the situation is slightly different and that is because nature is not always an exact science. It is a mixture of blended edges where rules are hazy and non defined.

 

The world, from a logical, rational standpoint related to evolutionary health, is better off because there are individuals within its societies who are not interested in a mate of the opposite sex.
