What can hand bones help determine about the deceased?

• A. They can provide clues such as height, occupation, or hobbies
• B. They reveal eye color
• C. They reveal blood type
• D. They reveal hair color

Answer: (A)

Hand bones carry information about both the person’s overall size and their life history. While stature is most accurately estimated from the long bones, the hand bones still contribute to the size profile and, importantly, show evidence of how a person used their hands. The muscle attachments and joint wear on metacarpals and phalanges can reveal habitual activities—repetitive gripping, tool use, or particular hobbies—through patterns of robusticity and entheseal changes. These activity markers can point to possible occupations or hobbies. In contrast, eye color, blood type, and hair color aren’t determined by the morphology of hand bones (eye color and hair color are genetic traits, and while DNA from bone can reveal some information, the everyday skeletal analysis focuses on the physical features of the bones themselves). So the hand bones are most informative for clues about height in the context of overall body size and, particularly, for activity-related clues that suggest occupation or hobbies.
