Handedness, Hair-Whorls, and Orientation

--- Quote ---"Knowing that each side (hemisphere) of the brain controls movements of the opposite side of the body, some scientists have looked to handedness to yield clues to how the hemispheres function. Adding greatly to the interest are reports that three times as many left-handed people have schizophrenia, bipolar disease (manic-depressive illness), or autism as would be expected from the population at large. A disproportionately high prevalence of left-handedness has been found, as well, in people with dyslexia and stuttering, in people with math and music prowess, and among people in intellectually demanding professions."

It is certainly interesting that left-handed people are more often being homosexual or musically gifted. However, I cannot withhold my doubts about the wide-spread opinion that all interesting scientifical findings are actually important... ::) From the scientifical point of view, it would be necessery to examinate why that many left-handed people choose an "intellectually demanding profession". Is it possible that the lack of appropriate tools for left-handed people hinders them to discover joys of handwork?

K6:

If gayness holds exclusively or mainly onto genetics,then the corresponding method to wipe us out exists and bears the name of genetic surgery and engineering.If however gayness holds onto human will,exclusively or mainly,than the stubborness of a certain number of individuals guarantees that we will never become extinct.

Feral:

--- Quote --- Much provocative research on left-handed people points to links between left-handedness and, for example, talent for music and mathematics, but also with autism and schizophrenia. Underlying these links, scientists have suspected, may be right-brain/left-brain differences, including which side of a person's brain is "dominant." Now, a leading geneticist has a theory that could explain a lot—perhaps even hair-whorl direction and homosexuality.

The PDF of the entire article is more intriguing than informative. Sadly, while this theory shows considerable promise in explaining the genetic origins of orientation, like most good work in genetics, it's a tad complicated.
