Sexual Dimorphism Determination from the Lineal Dimensions of Skulls

The sex determination from human skulls can be made by means of morphologic and morphometric methods have been broadly studied. These methods contribute with objective data; however, they present interpopulational variability. The purpose of this article is to determine sexual dimorphism using linea...
