Which category does diet belong to in skeletal evidence?

• A. Fixed evidence
• B. Genetic evidence
• C. Nutritional evidence
• D. Varying evidence

Answer: (D)

Diet records what a person ate, and those patterns are not constant. What people consumed changes with culture, geography, season, and personal circumstances, so the dietary signal in bones can vary widely from one person or population to another and over time. That inherent variability is why it’s categorized as varying evidence. It’s not a fixed trait like some skeletal features, nor is it strictly genetic. While nutrition-related bone changes can reflect nutritional status, the broader dietary signal itself is best understood as something that varies with context, hence the fitting label of varying evidence.
