Forensic Anthropology and Ancestry Identification from Skeletal Remains
This paper examines the role of forensic anthropology in identifying the ancestry of unknown skeletal remains to assist law enforcement investigations. It surveys the ongoing scholarly debate over the concept of "race" versus "ancestry," then systematically reviews the primary skeletal indicators used by forensic anthropologists — including nasal structure, facial profile, cranial vault features, jaw and tooth morphology, and post-cranial bones. The paper also addresses measurement techniques, the use of computers and forensic imaging, and the political and cultural tensions surrounding racial classification. Throughout, the discussion balances scientific utility with the acknowledgment that ancestry categories are imperfect and that significant variation exists within any ancestral group.

What makes this paper effective
- The paper grounds abstract concepts in concrete case examples — such as Norm Sauer's identification of a missing Black woman and John List's apprehension through forensic aging — making the methodology tangible for readers.
- It consistently balances scientific utility against cultural sensitivity, acknowledging both the limitations of racial categories and the practical necessity of ancestry estimation in law enforcement contexts.
- Systematic use of comparative summary tables (nose structure, facial features, cranial vault, jaws and teeth) organizes complex morphological data clearly and aids comprehension.
Key academic technique demonstrated
The paper demonstrates effective synthesis of a textbook source (Byers, 2001) with supplementary journalism and scientific articles to build a layered argument. Rather than simply cataloguing skeletal traits, the author contextualizes each trait within the broader debate over race as a biological versus social construct, showing how empirical observations are always embedded in interpretive frameworks.
Structure breakdown
The paper opens with an introductory section establishing the field through real-world cases, then transitions into a conceptual section questioning the definition of race. It moves from conceptual groundwork into applied methodology — ancestry basics, primary skeletal features, and quantitative measurement approaches — before closing with sections on supplementary methods (hair, computers, imaging) and a reflective discussion of the ethical and political dimensions of ancestry identification. This structure mirrors a classic problem-method-critique arc common in applied science writing.
Introduction to Forensic Anthropology
Forensic anthropology is a relatively new field within anthropology. When it was first recognized as a forensic science about thirty years ago, there were only six forensic anthropologists, all of whom knew each other (Guntzel, 2004). The role of forensic anthropology in police work is to give investigators specific information about an unknown individual that they can use to assist with identification. When investigators have such information as age, sex, height, and ancestry, they can compare it to records of known missing persons and perhaps identify the body (Byers, 2001).
One such forensic anthropologist is Clyde Snow, who has worked both on individual cases and on scenes of political massacres around the world, including Guatemala, El Salvador, Argentina, Iraq, Zaire, Ethiopia, Zimbabwe, and Yugoslavia (Guntzel, 2004). He has also gathered forensic evidence from victims of serial killers such as the Green River Killer and Jeffrey Dahmer, as well as from man-made and natural disasters including the Oklahoma City bombing (Guntzel, 2004). Other cases he worked on include identifying the remains of Butch Cassidy and the Sundance Kid, and bones found at the site of the Battle of Little Bighorn, where Custer and Union soldiers were defeated in battle with Native Americans.
Another forensic anthropologist, Norm Sauer, received a call from the Michigan State Police reporting that they had found a body in some woods. There was no identifying information, and visual inspection could determine neither race nor sex. He evaluated the entire skeleton but focused on the pelvis and skull. The pelvis confirmed the sex, and he also took measurements of the distance between the eye orbits and the length and breadth of the skull. After performing calculations, he told the state police that the remains were those of a Black female. He estimated her height at between 5'2" and 5'6" and placed her age between 18 and 23 years. He also determined that she had been dead for more than six weeks but less than six months. Investigators compared this information to known missing-person cases and found a match from the area: a Black woman, 5'3" tall, and 19 years old (Shreeve, 1994).
While history may be enriched by investigations into sites such as Little Bighorn, the most immediately useful work of forensic anthropology is identifying the remains of unknown individuals to assist police investigations. Of all the information generated by Sauer's work, the most difficult to establish was the race, or ancestry, of the unknown woman. Nevertheless, that information was crucial to determining who the missing woman might be.
