How does the female pelvis differ from the male pelvis?

• A. Women have a wider, shallower pelvis
• B. Women have a narrower, deeper pelvis
• C. The pelvis is identical between sexes
• D. Men have a narrow, deep pelvis while women have a wider, shallower pelvis

Answer: (D)

Pelvic morphology shows clear sexual dimorphism driven by reproductive function. The female pelvis is wider and shallower to create a larger birth canal, with a broader pelvic inlet and outlet, a wider subpubic angle, and flared ilia. The sacrum tends to be shorter and less curved. The male pelvis is generally narrower and deeper, with a heart-shaped inlet, a more acute subpubic angle, and heavier, thicker bones. This combination of traits makes the description that men have a narrow, deep pelvis while women have a wider, shallower pelvis the accurate way to capture the typical differences. In practice, these features help forensic anthropologists estimate sex from skeletal remains.
