BYU biology professor Bill Bradshaw has provided abundant evidence that sexual orientation is largely inborn. There is clearly no evidence that you would bother reading about or acknowledging.
Yeah right. There is probably more evidence that Freud's hypothesis of the dominering mother and passive father contributing to homosexuality than the stuff Bradshaw brings up. For instance:
According to a study on handedness in the Psychological Bulletin, homosexuals are more likely to be left-handed than heterosexuals, he said.
"There is a clear correlation between homosexuality and non-right-handedness," Bradshaw said.
Bradshaw said statistics show that homosexual individuals have a 39 percent greater probability of being left-handed than right-handed.
Other studies he cited said that homosexual men go through puberty significantly earlier than heterosexual men, homosexuality in men is linked with having at least two or three older brothers and finger length in homosexual women is increasingly masculineized.
http://newsnet.BYU.edu/story.cfm/49488Okay, so without asking for the sample sizes of the research he might fall back on I would ask what causes a correlation between being left handed and being homosexual. If a child is forced to use their right hand might that cause them to go straight rather than gay? Give me a break.
As for puperty, that generally is influenced by factors such as affluence/nutrition. It can even be linked to zinc as a study I read a while back said that Iranian boys go through puberty later than average due to a lack of zinc in their diet. I think it is safe to say that the people you see in gay parades are more likely to come from upper middle class or rich backgrounds. Wonder why that is.
As for women with more testosterone (the whole ring fnger thing) I have known women who have taken testosterone to boost their athletic abilities and none of them have reported getting more turned on in the women's shower room. More testosterone in a man or woman is likely to be associated with a higher sex drive and more competitive nature but that does not correlate to anything that would turn a woman more lesbian unless she is more likely to explore and experiment.
