Facial sexuality is a form of attraction between men and women. It can be done in many ways, but most often it involves a kiss or a kissing gesture. The sexual attraction between men and women is strongest when the facial features of each individual are strikingly different.
Men’s faces have allometric dimorphism and women’s have non-allometric dimorphism. If you want to learn more about this topic, check out my article on Maasai faces.
Faces of women have non-allometric dimorphism
There is no clear evidence to support the hypothesis that faces of men and women are equally attractive, though this does not rule out a role for morphological dimorphism. In fact, there is some evidence that women have a preference for masculine faces. In particular, Jamaican women prefer the looks of men with a more masculine face. The reasons for this may vary depending on the society or the context in which the face is evaluated.
Facial dimorphism has been suggested to be a biological marker of heterozygosity and health. Other studies have linked facial dimorphism to immune competence. However, more recent studies have cast doubts on these claims. While there are several possible biological mechanisms involved in facial dimorphism, none have been proven to explain the observed differences.
The relationship between male and female morphology and facial dimorphism has been studied in both animal and human populations. In humans, the size and shape of the head are related to body height and face size. Therefore, the relationship between head size and facial shape should be mediated by the head shape.
Faces of men have allometric dimorphism
Facial dimorphism is a natural trait of human beings and is influenced by both age and sex. Age-related changes in men’s faces are more intense than those in women. In addition, male faces are rounder than those of women. This is due to loss of skin elasticity and stretching of soft tissues.
Facial dimorphism can be observed among Maasai and other ethnic groups. Among them, the Maasai have wider faces than their counterparts. Other people with dimorphic faces include the Buryats, who originate from Mongolia.
Facial dimorphism can also be compensated by differences in skin color. For example, in Cameroonian women, lighter skin correlated with perceived femininity. On the other hand, lighter skin in men negatively correlated with perceived masculinity. Nevertheless, differences in facial shape do not necessarily indicate the presence of sexual dimorphism.
Although the findings are contradictory, they do suggest that sexual selection is a factor in facial dimorphism. The study of allometric dimorphism has largely been influenced by sexual selection in humans. This suggests that facial dimorphism in males may be an indirect determinant of the choice of mate. However, it is not yet clear whether this dimorphism is due to mate choice or not.
Maasai faces have non-allometric dimorphism
The male and female faces of the Maasai differ in many aspects. The male facial shape is generally more robust, with a larger lower face area, a more rounded chin, larger eyes, and a more pronounced radix. The female facial shape is softer and more squared, with less pronounced differences in length, width, and radix.
Previous anthropometric studies have suggested a connection between facial traits and climate. For instance, in wetter regions, the facial width increases and nose height decreases. This correlation between morphology and climate may be a possible explanation for the lower degree of facial sexual dimorphism among African tropical populations. People living in hot, wet environments have wider noses as a means of evacuating heat through expiratory mechanisms. This adaptation may not be compatible with a higher degree of dimorphism in faces.
Non-allometric dimorphism in facial shape is a determinant of body size. In African populations, there is a strong relationship between body size and facial dimorphism. In contrast, European and South American populations display less than average facial shape dimorphism.
Maasai faces have allometric dimorphism
Maasai faces are highly symmetrical, and male and female faces are remarkably similar. These facial traits are largely determined by processes of facial growth, and do not correlate with body size or overall shape. This pattern of sexual diversity in Maasai faces is in contrast to that seen in European populations, which have shown contradictory patterns of facial size. Nevertheless, we have documented significant differences between the genders in several areas of facial structure, and our results suggest that these differences are likely to be related to how faces grow and develop.
The ratio of facial width to face height is high in Maasai faces, and the mammalian cranium is shorter than in most humans. This may be due to the dolichocephalic condition. Furthermore, the Maasai face has a pronounced lateral-facial dimorphism, a pattern that may explain the differences in facial structure.
