In "Ancient Face" (pp. 14-15), you read about how John Gurche uses fossils to build models of ancient hominins. Gurche uses both observations and inferences about the remains to create the reconstructions. Study the definitions below. Then use them to identify which of the following statements about Homo naledi are observations (0) and which are inferences (I).

Observation: a statement about information obtained through one's senses

Inference: a conclusion that is based upon observations and not directly obtained with the senses
