Well, I’m not sure that we generally do agree about that. I have read a great deal of the research over time, and although sometimes a trend is identified, there’s still no god answer to the question of how gay people got that way. Since we see a rate of about 10% same-sex-directed mating behaviors in most (all?) chordates, it appears that there is a biological component in at least some cases. I suspect that some people have more of a predisposition for biological reasons and others form meaningful attachments early in life that dispose them psychologically, or both.
Is this the same study (or 30 year old TV show) the showed female rats eating their young? If so, your co-worker doesn’t need to worry about the crowding making him gay until folks are barbequeing suspicious things on the sidewalk. And it wouldn’t be the gay that I’d worry about.
Gay marriage.
No, wait.
Atheism!
Not all of us.
Interesting yes, but not one I believe we’re going to see anytime soon. There’s way to much social/cultural/religious noise surrounding the topic to allow for a valid academic approach. Studying animal behavior will only take us so far down that path.
:smack: I swear I hit preview…
I was also going to say that the environmental factors need not be limited to the mother’s womb. There are multiple biological precedents for organisms changing sex mid-life, various species of fish for example.
True, the Sheepshead fish, for example.
All sheepheads are born as females, and eventually change sex to males. The age of the transition depends on environmental clues such as food supply.[3]
Doesn’t the latest research indicate that homsexuality is cause by alcohol?
Well after a few too many, everyone looks sexy.
Are your left and right penises located below your enlongated central ballsack? If so, I have some horrible news to break to you concerning any and all anatomy teachers you may have had…
DrDeth, I’m sure you studied the behaviour of the mice in a lab, approved by an ethics committee, with funding from your faculty, and that you wrote an erudite and well-received paper on it.
So… why do I picture you in your bedroom, laughing maniacally, surrounded by cannabalistic, homosexual rodents…
It’s the user name.
Well, it was at a College, yes, but I paid for everything out of my pocket except “Purina Lab Chow” which they already had in bulk. There was no ethics commitee exept my Prof. He did like the experiment, which took two semesters over two classes.
As to the “cannabalistic, homosexual rodents”, it was a little manic, I’d have to agree. 
Not to mention smelly.
I will cheerfully concede Schroedinger’s Dog point- my user name would make a great super-villian name.
It’s tempting to respond to this by asking, “oh, is he gay then?” But I note that you’re living in North Wales, and I know my relatives from there wouldn’t be amused, so I won’t type it. It would have been funny if I did, though.
He is 6, a bit early to tell yet.
I couldn’t come up with a snappy comeback at the time. I was expecting some humorous response to it though.
Cerowyn, nice Japanese name.
So, it gayness the fault of Catholics and their big famlies?
I blame it on class size at state universities.
I have also read that the incidence of male homosexuality increases with the increasing number of older male siblings. This could possibly be related to the overcrowding theory. Futhermore the survival of the species really requires a lot less breeder males than females.
Look, I am Catholic and I have an older brother. I AM NOT HOMOSEXUAL.
Can everybody stop picking on me now, please.
Oscar: single son.
Santi: first son, has a younger male brother.
Rober: single son.
OK, it’s not much of a sample, but that’s the three gay people whose family “situations” I can remember without having to ask…
Denial!
