Which of the following is a type of scientific identification?

• A. Fingerprints
• B. Soil analysis
• C. Voice analysis
• D. Hair morphology

Answer: (A)

Fingerprints are a type of scientific identification because they provide unmistakable, lifelong patterns that can be matched to a specific person. The ridges and minutiae inside a fingerprint form uniquely for each individual and remain constant over a person’s life, allowing precise identification when a print is compared to a known reference. Soil analysis, while valuable for linking evidence to a location or context, doesn’t identify who a person is. Voice analysis can sometimes identify a speaker, but voice characteristics vary with aging, health, and recording conditions, making it less definitive. Hair morphology can help exclude individuals or narrow down possibilities, but it doesn’t typically pinpoint a single person due to shared characteristics among many individuals.
