Q:
You are an expert paleontologist reviewing the work of Professor Bonefinder, who recently discovered the remains of a primate fossil from South America. The fossil has a long snout, a tail, and large orbits that face toward the side and are only partially enclosed. The fossil has been securely dated to about 30 mya. Bonefinder concluded that this fossil is a hominoid. Do you think Professor Bonefinder's analysis is correct? Explain your evaluation.
