Researchers and scientists are constantly trying to find out what defines the sexuality of a person and how it can be identified. Well, looks like they have come up with a theory after all. Researchers at the University of Essex in the UK have now linked the length of your fingers with your sexuality.
Scientists measured the fingers of 18 pairs of female identical twins, where one was straight and the other gay. On average, the lesbians, but not the straight twins, had a different sized index and ring fingers, typically a male trait, but only on the left hand. This may be the result of exposure to more testosterone in the womb. They also measured the fingers of 14 pairs of male identical twins, where one was straight and the other gay, but well, they found no link.
Study author Dr Tuesday Watts, from the psychology department at Essex University, said, "Because identical twins, who share 100% of their genes, can differ in their sexual orientations, factors other than genetics must account for the differences. Research suggests that our sexuality is determined in the womb and is dependent on the amount of male hormone we are exposed to or the way our individual bodies react to that hormone, with those exposed to higher levels of testosterone being more likely to be bisexual or homosexual."
Watts added, "Because of the link between hormone levels and difference in finger lengths, looking at someone's hands could provide a clue to their sexuality."
The full findings of this research have been published in the Archives of Sexual Behaviour.
