Forensic anthropology
Anthropologists can study ancestry by studying which features of the skeleton are more common in particular populations compared to others. Forensic anthropologists collect data by measuring different features of the cranium, such as width, length, shape and thickness.  Once these measurements of the cranium are collected, the next step is to find an appropriate reference sample in the Forensic Anthropology Databank.  This databank can group the data from the individual into an existing reference group, giving an indication of the individual's ancestry.
