Why is a female skeleton smaller, and not as wide a male skeleton?
Can someone please explain?

A male's skeleton is usually thicker, rougher and appears more bumpy. ○ Due to the fact that males have larger muscles and therefore their skeletons require stronger attachment sites. Women who have borne children have scars on the surface of their pelvis. The femur (thigh bone) of a male is thicker than a females.
