"Forensic anthropologists utilize human craniofacial and postcranial skeletal morphologicalvariation to assist in personal identification during medicolegal investigations, predominately to estimate the decedent's ancestry. Typically, cranial metric and nonmetric morphological traits are used. However, to more fully understand the patterns of variation in modern populations, it is necessary to consider and analyze the frequency of trait expression and the distribution of those traits within and between populations, as well as to understand any secular changes affecting trait manifestation. This research focuses on the frequency distribution and inter-trait correlations of 17 cranial macromorphoscopic traits to demonstrate the ability of these traits as measures of secular trends. A sample of crania from Native African and American Black populations were used." -- Abstract.
