Question

7. The diagram illustrates the differences between the skulls and brain volumes of three extinct hominins. In each drawing in the diagram, the shaded area inside the skull indicates the size of the brain. Based on the relative size of the brain, which species is capable of more complex behavior, such as the use of tools? A. Australopithecus africanus B. All three species were capable of equivalent complex behaviors. C. Homo erectus D. Homo neanderthalensis

Answer 1

The best answer to the question above would be letter A. All species that were mentioned in the choices were capable of equivalent complex behaviors. The Australopithecus africanus probably used simple tools (which is an indication of complex behavior) such as sticks for hunting. The erectus and neanderthalensis developed more advanced use of tools.
