Scientists are once more speculating on the causes of homosexuality.
Now boffins are claiming they have discovered the 'lesbian ear'. Lesbianism is, they say, linked to an inner ear defect. According to Dr Dennis McFadden of the University of Texis, lesbians have a difference in their ear that means they hear less well than heterosexual women. This is, he claims, the first evidence of biological differences between dykes and their straight sisters. Dr McFadden says that lesbians, like men, tend to have marginally greater difficulty in hearinglow intensity sounds, such as the click of a light switch.
