Skulls can reveal many things about our hominid ancestors. What aspect of hominids is not related to skull anatomy?

A. What they ate.

B. Their hair and skin color.

C. Whether they stood upright.

D. The shape and size of their brain.

The answer is A, what they ate. I used the process of elimination to figure that out.

B.) hair and skin is directly on the skull, so people may easily determine it by examining the skull

C.) The way the skull is oriented can tell us whether someone is standing upright or not

D.) This one should be self explanatory. Since the brain is in the skull, you can find out how big the brain must have been in there
