Re: Homosexuality
The human genome is still being mapped and the brain is one of the greatest mysteries that we've yet to unravel.
Many scientists say that there are certain abnormalities which someone may have a genetic "pre-disposition" to and when certain environmental "triggers" occur, then the genetic abnormality blossoms.
This has been presented as a basis for things like autism, parkinsons, Multiple sclerosis and yes...homosexuality.
I tend to agree...that there is some kind of mis-wiring going on and that it can sometimes be overcome but if certain "environmental" effects occur then the defect can blossom.
