Question

How can you tell the age, race, and sex determination of a bone?

Answer 1

Forensic anthropologists determine the ancestry of a skeleton by examining the morphology, or shape, of the skull and by taking measurements of the skull vault (cavity) and face. By comparing these results with data from populations worldwide, scientists can evaluate that individual's relationship to a world group.

When viewed in profile, female skulls have a rounded forehead (frontal bone). Male frontal bones are less rounded and slope backwards at a gentler angle. This ridge along the brow is prominent in males and much smoother in females.

The appearance and fusion of these bones helps anthropologists determine the person's age. The fourth rib is also used to estimate age as the cartilage between the end of the rib and the sternum slowly turns to bone over time.
