When it comes to sex, human beings are divided into two fundamental categories: promiscuous or faithful, according to the latest study from the University of Oxford (United Kingdom), which represents the first scientific evidence that supports the theories that divide people into These two broad categories, contrary to what happens with other mammals (which are either polygamous or monogamous).
Why are humans the exception to the rule among mammals? For their study, the experts looked at two potential indicators of sexual behavior . First, a group of 585 people between the ages of 18 and 63 completed a questionnaire on sexual habits. Second, they analyzed data from an investigation (with 1,314 adult men) based on what is known as the “2D: 4D ratio” which measures the ratio between the lengths of the index and ring fingers as a statistical indicator of our sensitivity to sensitivity. testosterone. Thus, the longer the ring finger is compared to the index finger, the greater the probability of testosterone concentration; which has also been associated with a greater inclination towards promiscuity .
The comparative study of both data, published in the journal Biology Letters , revealed that 57% of men were more likely to be promiscuous and 43% faithful . Regarding women, the percentage was reversed: 47% were more inclined towards promiscuity and 53% towards fidelity.
According to the scientists, although these data must be taken with caution, “human behavior is influenced by many factors, such as the environment and life experience. This research suggests that there may be two different types of people within each sex who seek different mating strategies, ” explains Robin Dunbar, leader of the study.
