How do forensic anthropologists determine race?

Forensic anthropologists determine the ancestry of a skeleton by examining the morphology, or shape, of the skull and by taking measurements of the skull vault (cavity) and face. By comparing these results with data from populations worldwide, scientists can evaluate that individual’s relationship to a world group.
