Methods available to forensic anthropologists to help identify individualizing traits for positive identifications include all of the following, EXCEPT
A comparative medical radiography.
B comparative dental radiography.
C hair color analysis.
D identification of surgical implants.
The correct answer and explanation is:
The correct answer is C) hair color analysis.
Forensic anthropologists primarily focus on identifying individualizing traits based on physical characteristics and evidence from skeletal remains, rather than soft tissue features like hair color. While hair may provide some information in forensic investigations, it is not a reliable or definitive method for positive identification, especially when dealing with skeletal remains.
Here’s a breakdown of the other options:
- A) Comparative medical radiography: This method involves comparing radiographic images (X-rays, CT scans, etc.) of the remains with medical images of known individuals. Specific bone structures, fractures, or implants can be identified and matched to medical records, making it a valuable tool for identification.
- B) Comparative dental radiography: Dental records are often used in forensic anthropology, as teeth are some of the most durable parts of the human body. Unique dental features, such as fillings, root canal treatments, and distinctive wear patterns, can help match the remains to a known individual. Forensic odontologists work closely with forensic anthropologists in this process.
- D) Identification of surgical implants: Surgical implants like joint replacements, pacemakers, and other medical devices often have unique identifying information, such as serial numbers or specific models, which can be traced back to a particular person. This is an excellent method for making positive identifications when skeletal remains are involved.
Hair color analysis, while useful in some contexts (such as identifying a person in life), is not typically used for skeletal remains since hair does not survive well over time, and it lacks the specificity and reliability provided by skeletal markers. Thus, hair color analysis does not provide enough individualizing characteristics to be used as a primary method for positive identification in forensic anthropology.
