What type of evidence is characterized by its minute quantities, such as fibers or DNA?

Trace evidence refers to the subtle materials that can be transferred from one surface to another, particularly in small quantities. This type of evidence includes items such as fibers, hair, and DNA, which can be critical in linking suspects to a crime scene or victim. The defining characteristic of trace evidence is its minute size and the way it can be exchanged between objects or individuals without detection.

For example, when a person brushes against a surface, tiny fibers can come off clothing and cling to that surface, providing crucial links in forensic investigations. Trace evidence is often analyzed through sophisticated techniques, such as DNA analysis or microscopy, which allow forensic scientists to identify and compare this minute evidence with samples collected from suspects or crime scenes.

Understanding trace evidence is essential for investigations, as it can provide significant insights into the circumstances surrounding a crime, even when other forms of evidence may be limited or absent.
