Scientists have discovered how finger length affects the self-organizationBiologists from Oxford found that women who have on the left hand index finger longer ring are more likely to change. The study was published in the journal Biology Letters, reports the online edition of the Chronicle.info with reference to the Correspondent.
According to researchers, a longer index finger and a shorter unmarked due to exposure to estrogen in utero. Estrogens – female sex hormones that have a feminizing effect on the body.
Participants of the study were 274 women. Scientists measured their finger lengths, and took DNA samples, women completed questionnaires on their relationship. It turned out that the more of them the index finger (the correlation length index and ring fingers), the more they are impulsive and less satisfied with the relationship. Lead author of the study, Alund pierce calls the results “intriguing,” she’d expect the opposite effect.
The researchers suggest that women with a high index finger due to the estrogen the more feminine, which is more popular among men. Knowing that they have other options, such women are more willing to go to the cheating partner, especially when problems in the relationship.
“If women are more feminine figure, it increases its value on the “marriage market”, which can lead to dissatisfaction with current relationships and impulsive sex outside the relationship and find other partners,” the researchers write.
The researchers studied men and the index finger, however, had no relationship to self-organization. Did not affect her index finger at the women on the right hand.
The index finger is associated with the predisposition to many traits, including homosexuality – women who have different length of the index and ring finger, with likely lesbians. Scientists have measured the length of the fingers 18 pairs of female twins, one of whom was gay and the other straight.
It turns out that lesbians, unlike heterosexual women differed in the length of index and ring finger, as it usually happens in men.
However, the difference was noticeable only on the left hand.
The researchers attribute this effect with exposure to testosterone in the womb. Typically, women’s index and ring fingers are of equal length, and men are different. However, the effects of testosterone on the fetus during pregnancy could lead to such changes.
