Identify and briefly explain the significance of three skeletal and/or skull differences between apes and
hominids. What will be an ideal response?
The ape skull has prominent supraorbital ridges above the eye sockets whereas hominids lack this
ridge. Hominid faces are flatter than apes. The arrangement of teeth in an ape’s jaw is rectanguular,
and hominids have a u-shaped rounded jaw. Another trend in hominid evolution is an increase in brain
size accompanied by an increase in the cranium of the skull.
