Human females demonstrate higher religiosity than men in populations. Digit ratio (2D:4D), being a putative indicator of prenatal testosterone, is associated in varying degrees with characters that show sexual dimorphism. A small number of studies have indicated that religiosity may be associated with the biological basis of sex differences in humans. The objective of the present study was to ascertain whether 2D:4D in religiously oriented seminary students is different from individuals in other occupations. The study followed a cross-sectional design. Male participants of the study included 13 seminary students, 18 military chaplains and 91 control students from study courses relating to civil occupations. Lengths of second (2D) and fourth (4D) digits and their ratio (2D:4D) for each hand, height and weight were the variables and 2D:4D was the outcome measure. The results demonstrated that the seminary students had significantly higher 2D:4D than both the military chaplains and civil students. The military chaplains had the lowest 2D:4D. The study also revealed that the choice of religious occupation, and for that matter, religiosity, could be linked with the prenatal hormonal environment, particularly lower intrauterine testosterone compared to oestrogen.

The period of adolescence includes biological, psychological and social maturation. All these processes complement and affect each other. The ultimate goal is the transition from childhood to adulthood which enables individuals to become socialized beings, who are psychologically mature and able to pass on their genetic inheritance. In the process of reaching full maturity, adolescents are exposed to both positive and negative stimuli the socio-cultural environment. In the process of socialization, the influence of peers, and the maturing into social roles is important. At the same time, adolescents mature biologically. A holistic understanding of the sequence of changes that occur during adolescence foregrounds the significance of biology in informing emotions and cognition. Research conducted on adolescents from Wrocław, Poland, showed the impact that physical development plays on social development within a school peer group. Adolescents with a slower pace of maturity, lower BMI, and lower body height achieved the lowest social status in the group’s hierarchy. These adolescents also became victims of peer rejection. The role of scapegoat assigned to them highlighted and completed the symptomatic rejection process, which highlighted negative social group behaviours. In contrast, their peers from the same classes, with higher biological parameters, became leaders in the school’s social groups. Furthermore, sociometric ‘stars’, leaders and gray eminences, compared to scapegoats, achieved maturity faster, and had greater body height and higher BMI among all age groups.
