The size of the jaw and the back part of the skull Gizmo Warm-up In 1924, a fossilized skull that looked very similar to a chimp skull was discovered. But the skull most definitely did not belong to a chimp. The location of the foramen magnum—a hole in the skull where the spinal cord exits—indicated that the individual was bipedal, or walked on two legs. This fossil was some of the earliest evidence of human evolution. Using the Human Evolution – Skull Analysis Gizmo, you will discover some of the ways that skulls can be used to learn about human evolution. Start by comparing two modern hominids: a human and a chimpanzee. 1. Examine the Front view of the Homo sapiens (modern human) skull. Then, use the Select skull menu to examine the same view of the Pan troglodytes (chimp) skull. How do the skulls compare? The chimp’s jaw is much larger than a humans and the size of its head is also smaller than a human. 2. Now, examine the Bottom view of the two skulls. How do they compare? The chimp has a longer jaw than th [Show More]
