Activity: Is the Skeleton Male or Female?
The pelvis tells the story.
Distinct features adapted for childbearing distinguish adult females from males. Other bones and the skull also have features that can indicate sex, though less reliably. In young children, these sex-related features are less obvious and more difficult to interpret. Subtle sex differences are detectable in younger skeletons, but they become more defined following puberty and sexual maturation.
What are the differences? Compare the two illustrations below in Figure 1.

What Do You Think?
Comparing the skull from the cellar in Figure 5 (below) with the illustrated male and female skulls in Figures 3 and 4, check Male or Female to note the sex depicted by each feature.
