Prenatal Testosterone Finger-Ratio & Risky Behavior Tie Only In Men

RoseTracker| Last week we wrote that the fossil finger ratios of fourth and index fingers in Neanderthal men suggests that they were playboys, compared to modern humans. Researchers then made the argument we called a “leap of faith” arguing that modern man evolved into monogamy with the evolutionary changes in testosterone levels, as measured in the finger digit ratio.

Today’s study argues that the length between the second and fourth finger is an indicator of high levels of prenatal testosterone, resulting in risk-taking in recreational, social and financial spheres of a man’s life.

Most interesting, the study from Concordia University says that the same finger-length ratio comparison does not apply to women.

New research is casting some doubt on the definitive assertion made by Concordia doctoral student, Eric Stenstrom that “”Since women tend to be attracted to men who are fit, assertive and rich, men are apt to take risks with sports, people and money to be attractive to potential mates.”

In fact, sexually-interested women may be attracted to such a man, but new research posits that women may seek a different man for parenting.

This landscape remains very murky research-wise. The most interesting definitive in this study is the disqualification of women from the finger-ratio, prenatal testosterone exposure findings. via Science Daily
