Which combination of cranial characteristics is commonly used to identify male skulls?

• A. More pronounced brow bone, square chin, and sloped forehead
• B. Less pronounced brow bone, rounded chin, and flat forehead
• C. Small skull with delicate features
• D. Narrow nasal aperture

Answer: (A)

Sex estimation from the skull relies on cranial sexual dimorphism. In many populations, males tend to show more robust features such as pronounced brow ridges, a square-shaped chin, and a forehead that slopes backward. This combination—pronounced brow bone, square chin, and sloped forehead—best matches those male traits and is commonly used as a practical cue in forensic anthropology. The other descriptions describe features that are not as reliable for identifying male skulls: less pronounced brow ridges and a rounded chin with a flat forehead align more with female patterns; a small, delicate skull or a narrower nasal aperture can occur in both sexes and across populations, so they’re not definitive indicators on their own.
