Biological evidence refers to evidence that is derived from living organisms and can provide important information about a crime scene or a suspect's involvement in a crime. This type of evidence often includes bodily fluids such as blood, saliva, urine, and other organic materials, as well as plant materials.

Bodily fluids are significant because they can contain DNA, which is crucial for identifying individuals or linking them to a crime. Plant material can also be relevant, particularly in cases involving specific locations or activities tied to a suspect.

In contrast, fingerprints, living trees, and clothing fibers do not fit the definition of biological evidence in the same way. Fingerprints are regarded as latent evidence related to human impressions, living trees can be classified as environmental evidence, while clothing fibers are categorized as trace evidence. Therefore, the inclusion of bodily fluids and plant materials in biological evidence highlights how this type of evidence contributes to forensic investigations by offering cellular or genetic information that could be pivotal in solving a case.
