Do you still wish to pursue this PNT theme, or has it been covered elsewhere.

I'm having trouble understanding something. Where does it say it has to be any of the particular factors you mentioned? Why can't it be a combination of those factors?
Human sexuality, like all other human traits, are influenced by a combination of genetic factors, environmental factors, hormonal factors, and zeus knows what else. Now, if we were to talk about what rights should these people have because of their sexuality, I say choice or not has absolutely nothing to do with this issue. It shouldn't even be part of the debate, that whether a person can choose to be gay or not. So what if tomorrow I choose to be gay and the next day I choose to be straight?

I've been reading a little about phenotypic plasticity lately, a trait found in all organisms but spectacularly in insects and plants. It means that how an individual's phenotype (ie physical form) is created from its genotype (ie its DNA) depends on many environmental and other factors.
So it is entirely possible that a twin can be different - in fact all identical twins ARE different despite having identical genotypes - as an obvious example, they have different fingerprints, but there are always other subtle differences that enable family members to tell them apart. So, to take a giant and heroic leap in logic, perhaps we should now be looking for a difference in the very early upbringing or even birth of these two children that might have caused a difference in gene expression.

But they are not genetically identical, so why should we exclude genetics? There are plenty of studies on genetic\developmental differences in twins (google, birth defects among twins, scholarly articles)
Twins, triplets have greater chance of birth defects
quote: They say developmental effects rather than genetic. Even when they know they have genetic differences (MF twins).

Hi Taz,
Why can't it be a combination of those factors? Affecting one and not the other?
Human sexuality, like all other human traits, are influenced by a combination of genetic factors, environmental factors, hormonal factors, and zeus knows what else. Hormones are part of the environmental factors during gestation, as is zeus.
Now, if we were to talk about what rights should these people have because of their sexuality, I say choice or not has absolutely nothing to do with this issue. It shouldn't even be part of the debate, that whether a person can choose to be gay or not. ... And I agree that it has nothing to do with individual rights. But this set of twins shows that the behavior patterns started at a significantly younger age than sexual development.
... So what if tomorrow I choose to be gay and the next day I choose to be straight? Have you actually tried it? Curiously, I did when I was young and adventurous (free love hippy days), and it didn't work, even in mixed company. From my, admittedly anecdotal experiences, I conclude that one can only choose whether to express or repress the sexuality that one has.

Hi Tangle,
I've been reading a little about phenotypic plasticity lately, a trait found in all organisms but spectacularly in insects and plants. It means that how an individual's phenotype (ie physical form) is created from its genotype (ie its DNA) depends on many environmental and other factors. What other factors are there? I see environmental rather broadly (hormones and chemicals, temperatures, nutrients, etc), and we are talking about behavioral traits showing up rather soon after birth.
So it is entirely possible that a twin can be different - in fact all identical twins ARE different despite having identical genotypes - as an obvious example, they have different fingerprints, but there are always other subtle differences that enable family members to tell them apart. Implying that these are developmental differences rather than genetic differences. This would be good reason for random patterns in fingerprints for instance rather than family similarities.
So, to take a giant and heroic leap in logic, perhaps we should now be looking for a difference in the very early upbringing or even birth of these two children that might have caused a difference in gene expression. That is where I go on this one: developmental differences in when gene expression is keyed to occur. This is also consilient with the twin study cited above on birth defects.

The analysis seems too simplistic to me.We can rule out genetics. We can rule out upbringing. We can rule out "choice". What's left is fetal development - the process that builds a fetus from the genetic recipe - and a mutation in the progress of that development in one fetus. In a computer, there's a circuit called a flipflop. It contains two logic gates (probably more, but let's keep it simple). They are wired up so that they have to be in opposite states. If one is a "true", the other will be a "false". So maybe these are "flip-flop" twins. Perhaps they are innately ornery, competitive, and bound to be opposites. But it is arbitrary as to which is one way and which is the other. I am not suggesting that's the explanation in this case. I am only saying that this is a possibility that you left out in your analysis. I expect there are many other possibilities also left out of your analysis. My own view: We are not born homosexual or heterosexual. We are born sexual. And we have to find our own way to express that sexuality. There are probably many factors that will affect how we find our own way, including genetic factors, pre-natal environmental factors, post-natal environmental factors, plain chance, etc. I suggest we just accept that everybody is different in many ways, and that we stop the discrimination.Jesus was a liberal hippie

The factors can be absolutely anything from pH, temperature, hormones/pheromones, oxygen levels, presence of competitors or enemies - even physical touching. (!)

We can rule out genetics. We can rule out upbringing. We can rule out "choice". What's left is fetal development - the process that builds a fetus from the genetic recipe - and a mutation in the progress of that development in one fetus. I take issue with all three of your claims, and more generally reject the model under which you make them Claim 1: Genetics. Two issues emerge: firstly, there's the question of whether they're actually genetically identical - has this been tested? Or, as it usually the case, are they assumed to be identical based on very similar morphology? It's not uncommon for twins to misclassified as identical. Even if they're monozygotic, it is quite possible for gene mutations to occur in one twin but not the other. Secondly, if we take a broader view of genetics, it's quite possible that the epigenetics of the twins are different. Claim 2: upbringing Who says their upbringing was the same? Are we sure that, for example, the parents didn't pick up the differences in their play behaviour and encourage them, wanting to ensure their two sons developed different identities? Claim 3: choice Why can we rule out choice? Did Wyatt not choose tutus and beads? Did he not choose to demand a barbie cake? What is choice, anyway? The idea that it is only a choice if we could trivially choose differently is naive, at best. Finally, I reject the framework underwhich you're working. Environment is wider than upbringing and the idea that the influences of genetics and environment can be separated is simply wrong. Many, probably most, genes - especially those for complex characteristics - interact with the environment is extremely varied ways. The influence of environment is only possible if the genes allow it. In a way, all traits are 100% environmental and 100% genetic.

I wonder, any of you who are seriously considering that choice has anything to do with sexual orientation or gender identity (two completely separate subjects, I might add - a transgendered woman is in no way a homosexual man, for example), was there a time when you chose to identify as your biological gender, or to be attracted to the gender(s) o which you are attracted?
For the life of me, I cannot recall a moment in time where I chose to identify as male, nor a time when I chose to find women sexually attractive and men not. I've spoken to quite a few gay and transgendered individuals. They report a similar experience in terms of choice - they had moments of realization where they figured out that something was different (ie, a person who identifies as female noticing that the other girls are biologically different from her, or a homosexual person noticing that most of their friends are attracted to a different gender, etc), but not a single one of them had a moment where they decided anything in those regards. You don't choose who you find attractive. You don't choose which gender identifies you. And even the choice to transition genders is not just a matter of preference - it's correcting a problem. Transgendered individuals don't just want boobs or a penis. They aren't crazy. It's become cliche, but they really do feel trapped in the wrong body. You know those ridiculously bad comedy movies that involve a man and woman swapping bodies? Remove the bad comedy and focus on that moment of distress that a real person would feel in such a situation - having your body reflect a gender different from your identity. How do you think that would feel? That is what a transgendered person feels. And that's why many of them seek to have their physical gender surgically and chemically reassigned to match who they are, since in real life there's no poorly written "comedic" plot device that puts everyone back in the right body by the end of the terrible movie. For the rest - identical twins studies have long been accepted as strong evidence in determining genetic factors, and I see no reason to disregard that fact simply because we start talking about sexual orientation and gender identity. Like all studies, you can't take a single case and pretend it has statistical significance...but when we have a plurality of twins studies and they all seem to show that neither genetics nor environment seems to be a factor in determining gender identity or sexual orientation, we should certainly pay attention.The human understanding when it has once adopted an opinion (either as being the received opinion or as being agreeable to itself) draws all things else to support and agree with it. - Francis Bacon "There are two novels that can change a bookish fourteen-year old's life: The Lord of the Rings and Atlas Shrugged. One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world. The other, of course, involves orcs." - John Rogers A world that can be explained even with bad reasons is a familiar world. But, on the other hand, in a universe suddenly divested of illusions and lights, man feels an alien, a stranger. His exile is without remedy since he is deprived of the memory of a lost home or the hope of a promised land. This divorce between man and his life, the actor and his setting, is properly the feeling of absurdity. — Albert Camus "...the pious hope that by combining numerous little turds ofvariously tainted data, one can obtain a valuable result; but in fact, the outcome is merely a larger than average pile of shit." Barash, David 1995.
