What is commingling in forensic anthropology?

• A. The recovery of remains from more than one individual in a single context, complicating disassociation and biometric profiling
• B. The recovery of a single individual
• C. The process of dating bone
• D. The mixing of isotopes

Answer: (A)

Commingling is the recovery of remains from more than one individual in a single context, which makes it hard to separate which bones belong to which person and to reconstruct accurate biological profiles. When fragments from multiple people are mixed together, determining how many individuals are present, assigning each bone to the correct person, and interpreting factors like age, sex, or stature becomes much more challenging. This situation is especially common in mass fatality or disaster scenarios, where rapid recovery results in a pool of mixed remains.

To work through commingling, investigators meticulously sort and document bone fragments, look for anatomical fit and articulations, compare dental and skeletal characteristics, and assess taphonomic signs to distinguish perimortem from postmortem changes. When possible, they supplement these steps with DNA analysis or other identification methods to correctly separate the individuals. This concept is distinct from simply recovering a single individual, dating bone, or analyzing isotopes, which address different questions or processes.
