Study shows M. homosexuality can be explained through a model of Darwinian evolution

It's true, this doesn't prove whether it is causation or effect. But I can't think why a lesbian woman would have better spacial awareness than a heterosexual woman, just because she is a lesbian.

Maybe having a better awareness of spacial relations makes one more attracted to women? *wink*

Haha, I was going to say something like that!

The interesting thing is that in IQ tests, my spacial awareness always comes out higher than anything else, and I was born straight.

Actually, letting a certain type of wound "bleed out" will get all or most of the foreign objects in it out, thus preventing infection. So you can, sort of, use blood to help disinfect a wound (though using antibiotics is certainly also a good idea).

Thats...random. Thank you for telling me that WatersMoon.

You do realize that you are using, at best, impolite words? Abnormal and defect have a distinct negative connotation. Do you consider blue eyes to be defective? They are not the norm.

When I can eat a sandwich through my blue eyes, then, considering a woman with a man's brain not an abnormality may make sense. It's all about the rest of the body too. Genitals point to sexual orientation.

No they do not. The brain points to orientation. The genitals point to excretion.

But who decided that was a "man's brain?" Maybe men with those brains have women's brains, and women with the OTHER type have "men's brains." It's a very subjective standard. Unless your brain has genitals on it, you can't really "gender" it other than saying "There is this type of brain, and then this other type of brain."

No they do not. The brain points to orientation. The genitals point to excretion.

Hmm, my doctor would disagree with you. And what they (genitals) excrete is not designed for the mouth or rectum (and vice versa). Follow the logic brick road to enlightenment and reality.

Then you should find a new doctor. Immediately.

And what they (genitals) excrete is not designed for the mouth or rectum (and vice versa). Follow the logic brick road to enlightenment and reality.

Heh. Reality. That's funny to hear coming from someone who believes in spirits, talking animals, and the dead rising.

...And your doctor would be wrong. Your orientation (what you are attracted to, sexually and romantically) is based in your brain. Your genitals do not tell you who you are attracted to, your brain does.

Also, as a sidenote, I feel really, REALLY bad for you if you actually have missed out on the wonders of mouth-to-genital activites.

 

[IzzyPop]

Hmm, my doctor would disagree with you.

One piece of advice when picking a doctor. Half of them graduated in the bottom of med school. I think you got one of those.

And what they (genitals) excrete is not designed for the mouth or rectum (and vice versa). I never said they were. Ever hear of pulling out?

Follow the logic brick road to enlightenment and reality.

A reality involves zombies, invisible sky daddies, talking animals, and cannibalism? I'll pass. Thank you, though.

And in other news, gay men have similarly shaped brains to heterosexual women. And lesbians have similarly shaped brains to heterosexual men. Who would have thought it?

http://www.guardian.co.uk/science/2008/jun/16/neuroscience.psychology

Striking similarities between the brains of gay men and straight women have been discovered by neuroscientists, offering fresh evidence that sexual orientation is hardwired into our neural circuitry.
Scans reveal homosexual men and heterosexual women have symmetrical brains, with the right and left hemispheres almost exactly the same size. Conversely, lesbians and straight men have asymmetrical brains, with the right hemisphere significantly larger than the left.
Scientists at the prestigious Stockholm Brain Institute in Sweden also found certain brain circuits linked to emotional responses were the same in gay men and straight women.
The findings, published tomorrow in the US journal Proceedings of the National Academy of Sciences, suggest the biological factors that influence sexual orientation - such as exposure to testosterone in the womb - may also shape the brain's anatomy.
The study, led by the neurobiologist Ivanka Savic, builds on previous research that has identified differences in spatial and verbal abilities related to sex and sexual orientation. Tests have found gay men and straight women fare better at certain language tasks, while heterosexual men and lesbians tend to have better spatial awareness.
Savic and her colleague Per Linström took MRI brain scans of 90 volunteers who were divided into four groups of similar ages according to whether they were male, female, heterosexual or homosexual. The scans showed the right side of the brain in heterosexual men was typically 2% larger than the left. Lesbians showed a similar asymmetry, with the right hand side of the brain 1% larger than the left.
Scans on homosexual men and heterosexual women revealed both sides of the brain were the same size.
The results could explain a University of London study earlier this year that found gay men and straight women share a poor sense of direction compared with heterosexual men, and were more likely to navigate using landmarks alone.
......

Brain structure changes over time and can be induced by repetition of activities, emotional states, or even drug use.

BTW, the article says "could" be explained, which is Scientist for "I am hypothesizing".
