Which subfield involves the evaluation of physical evidence such as fibers and hairs?

The subfield that deals with the evaluation of physical evidence, specifically fibers and hairs, is forensic biology. This area of forensics focuses on the analysis of biological materials in a legal context. Forensic biologists examine various forms of evidence that include, but are not limited to,DNA profiling, blood spatter analysis, and the study of hair and fibers.

Fibers and hairs can provide critical information about a crime scene, such as linking a suspect to a victim or indicating contact between individuals. Analysis can help determine characteristics like species origin, color, and even the location where the fibers were likely produced. This type of evaluation can ultimately aid in establishing connections between individuals involved in a criminal investigation.

In contrast, forensic chemistry primarily involves the chemical analysis of substances, such as drugs and poisons, while forensic anthropology focuses on the identification and examination of human skeletal remains. Forensic toxicology, on the other hand, examines bodily fluids and tissues to identify potential toxins or poisons. These subfields are essential for a comprehensive forensic investigation but do not concentrate on the analysis of fibers and hairs specifically.
