Question 49

Fossil remains of the hominid Australopithecus afarensis were discovered in East Africa.

Figure 1: Simplified diagram of a sedimentary rock profile. The deepest layer, Layer 3, contains fossils of Australopithecus afarensis. The middle layer, Layer 2, contains fossils of Homo habilis. The upper layer, Layer 1, contains fossils of Homo erectus. All layers are undisturbed.

Describe the evidence that scientists could use to show that Australopithecus afarensis inhabited the Earth earlier than Homo erectus.
