Type of Circumstantial Evidence: ______ evidence: body or body parts, body fluids, hair, leaves or other plant parts, natural fibers, feathers, wood

• A. Biological
• B. Physical
• C. Trace
• D. Class

Answer: (A)

The key idea here is that evidence is categorized by its origin, specifically whether it comes from living matter. The items listed—body or body parts, body fluids, hair, leaves or other plant parts, natural fibers, feathers, and wood—are all organic materials that come from living organisms or once-living sources. Because of their biological origin, they are best described as biological evidence. This distinguishes them from physical evidence, which encompasses non-biological materials like metal or glass, and from trace evidence, which focuses on small, often microscopic materials; the emphasis in this grouping is the biological origin rather than size.
