1. Evolutionary Foundations of Sexual Dimorphism
Sexual dimorphism in humans is deeply rooted in evolutionary pressures of mate choice and sexual competition. Across hominin evolution, facial structure evolved not only to house sensory organs and the brain, but also to communicate developmental quality. Male and female craniofacial geometries diverged under the influence of sexual selection, with male faces typically developing larger, more angular jaw and more projected cheekbones, while female faces evolved softer contours and more even facial proportions. These differences are mediated by hormones, particularly testosterone and estrogen, which shape bone growth and soft tissue distribution during puberty and adolescence.
Facial dimorphism is also linked to symmetry, a well-established marker of developmental stability. Symmetric faces tend to present more sex-typical proportions, indicating a shared developmental mechanism that integrates overall growth stability with sexually dimorphic traits. These signals provide clear, high-information cues about an individual’s developmental history, hormonal exposure, and overall genetic robustness.
2. Neural and Perceptual Processing
Humans process these dimorphic cues with remarkable speed and precision. Specialized brain regions, including the fusiform face area and the amygdala, are activated within milliseconds when viewing facial geometry, enabling rapid assessment of features that signal health, sex, and developmental integrity. Angularity, jaw projection, cheekbone prominence, and symmetry are not merely aesthetic.
Experimental studies manipulating facial geometry show that even subtle changes in jaw width, cheekbone height, or lower-face length can significantly influence perceived masculinity, dominance, and attractiveness. These perceptual biases reflect the evolved importance of reading developmental and endocrine cues accurately.
3. Dimorphism in High-Profile Faces
John E. Hexum would be a good example how male-typical facial dimorphism manifests in a living, high-profile individual. His jawline is angular with a 118 degree gonial angle, mandibular plane angle of 15 , 90 degree jaw frontal angle , projecting strength without exaggeration; his cheekbones are high set at around 85%, laterally prominent, providing structural support to soft tissues while enhancing symmetry; his midface is balanced at a 1:1 ratio , integrating each plane harmoniously. These traits are not simply stylistic or culturally admired, they are high/desirable biological signals of androgenic exposure, skeletal robustness, and developmental stability. Hexum’s face communicates competence, health, and genetic quality in a way that aligns with evolutionary signaling theory.
Female supermodels demonstrate analogous principles. Cindy Crawford’s pronounced cheekbones, Gigi Hadid’s midface, Karlie Kloss’s top tier jaw area and Linda Evangelista’s angular yet balanced features illustrate how high-fidelity sexual dimorphism and angularity can exist in women without crossing into male-typical morphology. Their features reflect estrogenic and developmental optimization, providing perceptual cues of symmetry, health, and vitality. These examples underscore that angularity is not inherently masculine. it is a signal of optimized development, communicable across genders.
4. Developmental and Morphometric Mechanisms
Underlying these phenotypes are morphometric and developmental mechanisms. Mandibular and maxillary growth trajectories, governed by osteogenic and hormonal factors, determine jaw size, gonial angle, and overall lower face projection. Facial shape variation emerges from the interaction of endocrine signaling, bone growth, and soft tissue distribution. Sexual dimorphism is expressed through these pathways but is modulated by overall craniofacial geometry, body size, and environmental factors.
Facial angularity often reflects the intensity of androgenic exposure in males or estrogenic modulation in females. Symmetry, proportionality, and vertical facial height act as mediators, ensuring that angular features are integrated harmoniously with the overall facial template. These mechanisms explain why individuals like John E. Hexum or top supermodels consistently exhibit forms that the human perceptual system reads as highly attractive and biologically informative.
5. Modern Aesthetic Science
Aesthetic medicine can enhance or refine the same developmental signals that evolution sculpted. Non-surgical interventions, such as orthodontic realignment, orthotropic guidance, postural training, and fat distribution management, can reveal latent skeletal structure by clarifying planes and reducing soft-tissue interference. Minimally invasive procedures, including dermal fillers, neurotoxins, and localized fat reduction, operate as microtopographical adjustments, refining contours, cheek projection, and jaw definition. Surgical interventions, such as genioplasty, zygomatic advancement, and mandibular reconstruction, alter the underlying skeletal architecture to permanently amplify perceived dimorphism and angularity.
6. Sort of summary
Sexual dimorphism and angularity are not merely aesthetic ideals, they are biological imperatives and perceptual truths. John E. Hexum’s face, with its precise jaw, high cheekbones, and integrated planes, exemplifies male typical dimorphism, while supermodels such as Cindy Crawford, Gigi Hadid, Karlie Kloss, and Linda Evangelista illustrate how angularity and high dimorphism can manifest in female forms.
These faces communicate competence, health, and developmental stability because they are structured, proportionate, and harmonious reflections of biological optimization. Modern aesthetic interventions allow humans to interpret, refine, and amplify these evolutionary signals without violating the underlying principles of encoded in the skeleton.
