Here is another way to look at it from an evolutionary sense.

One way for a population to survive that is over populated is to stop reproducing. Homosexuality is one way of doing this. In other words homosexuality may well be a behavioral adaptation to over crowding.

Of course there are problems with this as well since this requires a selection against certain individuals for the survival of the group as a whole.

However homosexual behavior is seen in tons of animals as these links document.

So I don't think we can rule out homosexuality from an evolutionary stand point until more research can be done.

So you're saying that it's biological, but not part of the evolutionary process?
I guess I fall into the 'atomistic' catagory. I equate the instinctual urge to procreate with biology because it takes obvious form there. We're just built to work that way (male/female)to procreate. The biology of hetero sex is as plain as my dick. The instinct of using it whenever possible and with a mate that could pro-create serves the instinct for survival (continuing a bloodline).
From that standpoint, it would seem awful strange that a body would be wired to act in a way millions of years of evolution has spent specifically designing human sexual process to the point it is today.
But this assume that the body is only wired up in the sole pursuit of procreation and derives nothing from inputs like pleasure, emotion, etc. If sex means more to even our base instincts, then the biology should be there to show it.
I'm not a biologist. As such I need someone to say: "here, this is a gene/enzyme/RNA/whatever that either makes someone override the obvious biology of thier body on a chemical level and be gay.
I don't discount it's there. But I don't know of any evidence that's been generally accepted as scientific proof. It's not a topic I really give a damn about, I just got sucked into the conversation long enough to offend people.

I'm guessing that prisons are just one example of how the male sex drive doesn't necessarily show that it's geared for an exclusive male/female/procreation outcome. Our biological preference in general may be to have sex with a partner that is capable of producing offspring.

But when such a partner isn't available, it seems as if our sex drive in many cases shows that the desire to just get off is more powerful than our desire to procreate.

Are you going to refer to this in every post you make from now on? Bygones anyone?

No I am saying it may be biological and if it is, it would have been part of the evolutionary process.

What I gave was a possible explanation (scenario) where homosexuality could evolve in a population as a compensation for over population. However I do object to this explanation because it does the homosexual individual little good in terms of survival although it does help the group as a whole.

So the real question is, can natural selection select for a behavior that kicks in when populations start to exceed natural carrying capacity.

Now since other animals do it, we have to ask is it from biological reasons or is it because they choose to do it?

I personally am leaning towards a biological behavioral issue effected by the environment and nurture and by various hereditary issues. This could explain its evolutionary origin since the phenotype would be suppressed when conditions did not promote homosexuality (e.g. in my scenario above when population levels are low) so the genetic traits could be carried on and then the phenotype expressed when the situations are right (high population levels for instance).

Definitely not. Anton LaVey of the Church of Satan's birth name was Anthony Levey (or Levy- not 100% sure).

Just a stage name, really.

I'm with Gorgo. Why does everything need a lable? Can't things, people or whatever just be what they are and accepted (or not) for that? Yeah it's interesting to examine stuff, find out answers but for practical everyday life, let it be. In other words, don't get worked up over things you can't change or that aren't your business.

Sorry to lift this out of context but your comment truly pains me. My Mother had terminal cancer but what actually killed her--well ahead of time--was that she wasted away. She didn't want to eat anything; she couldn't even stand the smell of food. Marijuana is widely reputed to reverse that effect so typical of those being treated for cancer---"the munchies" it is usually called.

My sister died about 30 years ago of what today might be called "anorexia". She, too, wasted to a near skeleton. Despite doing her best to eat and put on weight, she didn't seem to be able to do it---she just couldn't get the food down. Once again: marijuana might---just might---have saved her life.

The effects of marijuana in fighting certain eye-diseases are well documented.

I think that you were rash in your statement and am amazed that no one on this usually quick-to-attack Board didn't call you on it.

I think at that point in his stay at SFN, I had ceased to read most of Solly's posts, save for the ones in threads I was involved in. He seemed to be taking the comments made on this board entirely too personally. I'd like to say I would have called him on that had I read it.

I believe that, as a species, human beings define their reality through suffering and misery.

Boron10, PhDreamer: At the risk of offending the following maxim from one of humanity's larger cultures: "Only a fool shows his teeth", I respond to your posts with:

As to PhDreamer's comment, I must admit that I wasn't surprised about poster Solly's HighlyBiased commentaries. To again quote a proverb from the same culture:
