In forensic anthropology, how does the female pelvis generally differ from the male pelvis?

• A. Taller
• B. Narrower
• C. The same width as males
• D. Wider

Answer: (D)

The main idea is sexual dimorphism in the pelvis driven by childbirth. The female pelvis is wider and more open than the male pelvis to accommodate a baby during birth. This shows up as a larger pelvic inlet and outlet, a wider subpubic angle (the pubic arch is more obtuse), and flaring of the ilia. The sacrum tends to be shorter and less curved, and the greater sciatic notch is wider in females. These features collectively make the female pelvis broader in overall width. The other options don’t reflect this characteristic pattern—height isn’t a pelvic trait, the pelvis isn’t generally narrower, and it isn’t the same width as males.
