What is a common feature of the male upper brow ridge?

The male upper brow ridge is typically characterized by its thickness and prominence, making it a distinguishing feature in forensic anthropology and biological sex determination. Males generally have thicker and more pronounced brow ridges, which result from the influence of testosterone during development. This feature is evolutionary, as it serves various functions, including protection of the eyes and support for facial musculature, which can relate to overall physical robustness.

In terms of anatomy, a pronounced brow ridge is more commonly found in male skulls, serving as a point of reference in forensic science for estimating sex from skeletal remains. The distinctive size and shape of the male brow ridge contrast with female characteristics, which tend to display more subtlety and less pronounced features.
