What is dactylography the study of?

Blood samples
Fingerprints
Human bones
Psychological profiles

The correct answer is: Fingerprints

Dactylography is the scientific study of fingerprints. This field focuses on the analysis, comparison, and classification of fingerprints and is crucial in forensic science for identifying individuals based on their unique fingerprint patterns. The uniqueness and the permanence of fingerprints make them a reliable biometric method for personal identification in criminal investigations, civil applications, and other law enforcement contexts. Understanding dactylography is important for investigators as it allows them to connect suspects to crime scenes or verify identities in various situations. Other options, while related to forensic science, pertain to different areas of study, such as toxicology for blood samples or osteology for human bones, which do not fall under the scope of dactylography.
