Final answer:
A forensic anthropologist must first determine if the examined remains are human before proceeding with further analysis.
Step-by-step explanation:
The first question a forensic anthropologist must answer when examining remains is whether the remains are human. This determination is crucial because it directs the subsequent steps of the investigation and analysis. After confirming the remains are human, the forensic anthropologist's role then shifts to approximating the individual's age, sex, race, and height to assist the forensic pathologist with the overall determination of the cause of death.
