Which cranial characteristics are associated with male sex determination?

• A. More pronounced brow bone, square chin, and sloped forehead
• B. Less pronounced brow bone, rounded chin, and flat forehead
• C. Smaller skull overall
• D. Narrow nasal aperture

Answer: (A)

Cranial features show clear male–female differences, and this combination captures the most reliable male markers. In male skulls, the brow ridge (supraorbital torus) tends to be more pronounced, the chin is often square and strongly defined, and the forehead slopes backward rather than staying flat or vertical. These robust traits reflect the typical pattern of sexual dimorphism and are the best indicators among common skull traits for identifying male remains. The opposite pattern—less pronounced brow ridges, a rounded chin, and a flat or vertical forehead—aligns with female skull morphology, which is generally smoother and less robust. While skull size can vary and overlaps between sexes exist, size alone isn’t as dependable. Likewise, a narrow nasal aperture isn’t a definitive indicator on its own due to population variation.
