AlaskaBoy:
We wouldn't be a species at all if we were all female. This has nothing to do with homosexuality, and doesn't diminish my point.
PhysicsGirl:
Gender is not directly correlated to sexual orientation, however my analogy has as much merit as your "point" does. We're not all female and we're not all gay. So what?"
***First of all- you're confusing "gender" with "sex", and are you you being serious right now?! "Gender is not directly correlated to sexual orientation?" You have to be kidding right now. Why do you think homosexuality is a deviation? What do you think deviation even means? Sex is EXACTLY correlated with sexual orientation.
Secondly, you miss the point again, so allow me to put it another way that perhaps you'll understand. If we were all female, it wouldn't matter if we were homosexual or not- everyone would have XX chromosome pairs, and sexual reproduction would be impossible.

AlaskaBoy:
Homosexuality is indeed found in instances in other species. This does not, however, mean that that entire species will die out,
PhysicsGirl:
So why bring it up? It's completely pointless.
***Firstly, It was originally your point- not mine. You first stated that "If [homosexuality] were detrimental to the continuation of a species, we wouldn't see it expressed in our population or in the multitude of other species which demonstrate homosexuality."
Secondly, the original point still stands: If every part of that species was homosexual, it wouldn't reproduce. Since only very small portions of certain species indicate homosexual behavior, it means that the majority does not, ergo the species continues because of the normal, natural cycle of reproduction.

AlaskaBoy:
it means that the instances of homosexual creates do not reproduce, and subsequently, do not pass their flawed genes on to the next species.
PhysicsGirl:
Ah, but even if a homosexual individual doesn't have progeny they often have siblings. The fact that this trait has been expressed in so many other species indicates that the genetic component may be beneficial in some instances. Of course, the causes are not well understood at this time so further study is necessary.
***I have no idea where you are getting this from. There is neither data indicating that being homosexual is "beneficial", (except that it does not exist in the vast majority of people), nor scientific evidence that homosexuality is hereditary, so I don't know where this "sibling" component is coming from.
Ultimately, flawed and mutated genes are what science is looking more and more at in describing someone with homosexual tendencies. There are now defined and marked differences in brain behavior and brain physiology than other people. Fix this, and you could address homosexuality in general, the point of the article.
