How is the female upper brow ridge typically described?

The female upper brow ridge is typically described as thin and slender. This characteristic is a result of the general differences in skeletal structure between males and females. In females, evolutionary factors tend to contribute to a softer facial structure, which includes a thinner brow ridge.

Males, on the other hand, generally exhibit a more pronounced brow ridge that is thicker and more prominent, reflecting their differing hormonal influences and evolutionary adaptations. Consequently, a thin and slender brow ridge is a key feature that distinguishes female skulls in forensic anthropology and can be critical for sex determination in skeletal remains.
