Homosexuality in humans is not necessarily normal or natural because it can be found elsewhere.
True, but it certainly strengthens the case, especially considering that all of our closest relatives in the animal kingdom display homosexual behavior.
Let us ignore the display of the behavior and jump directly to genetics. We do know that sheep can be altered as can fruit flies to have homosexual wiring so while it may be a natural mutation it is still not exactly normal in any given population that doesn't inherently thrive on this principle. Humans definitely do not. It is a question however of it's natural elements in genetic variation since we claim to have, as a species anyway, found the gay gene. We've not seemingly done anything with it though. Now whether this is true or not is up the air.
Understand that not everything we are is up to genetics alone, genetics are important but so is environment, in fact it makes little if any sense to separate the two as environment can effect which genes are expressed. Also understand that just because a behavior is abnormal (meaning that it deviates from the norm) it is not therefore bad. It's also worth noting that simply because a behavior is natural, it is not therefore morally acceptable, that's a different conversation entirely.
I have never seen anything that expresses that homosexuality as humans define it is a by-product or even effected by environment. As for the rest dealing with what is good or bad and what abnormal entails these are different conversations. For where it stands I would like to see reason not to separate environment from genetics in this case: the case for humans.
There is most certainly a genetic component in homosexuality, however almost nothing is genetically predetermined. If homosexuality WAS genetically predetermined we would expect certain things, like we would expect identical twins (who share the exact same genetic code) to both be homosexual, if one of them is, 100% of the time. However that is not what we see, what we see is that when one identical twin is homosexual, the other is homosexual 70% of the time. Meaning that there almost certainly IS a strong genetic component, but it is not genetically predetermined, and if it's not genetically predetermined, then environment has an effect on it.
