Rounder features and less prominent brows indicate lower levels of testosterone acting on the skeleton.

Researchers at Duke University performed comparisons between more than 1,400 modern and ancient skulls. They found that around 50,000 years ago facial features became rounder and the upper part of the face shorter. On the basis of studies in animals, scientists know that these traits can be directly traced to the influence of testosterone.
