Question

What are the answers to problem 2?

2. This question may be completed independently or as a group exercise. Below are descriptions for five mystery fossil primates. Use the information provided to determine which mystery fossil primate is an adapiform, an omomyoid, a New World monkey, an Old World monkey, or an ape. Mystery fossil primate A lived in the early to middle Miocene in South America. It had an enclosed bony orbit, three premolars in each mouth quadrant, and dentition suggesting a frugivorous and folivorous diet. Its postcrania indicate it was a quadruped. Mystery fossil primate B lived in the early Eocene in North America. It had an unfused mandible, long snout, and small forward-facing orbits. It had sexually dimorphic canines and teeth that suggest a frugivorous diet. Its postcrania indicate some leaping behaviors. Mystery fossil primate C lived in the late Miocene and Pliocene in Africa. It had two premolars in each mouth quadrant, bilophodont molars, and dental adaptations for folivory. Its postcrania suggest it practiced a combination of arboreal and terrestrial quadrupedalism. Mystery fossil primate D lived in the middle Miocene in Europe. It had two premolars in each mouth quadrant. It had a flexible wrist, a broad chest, and short fingers. It is likely that its scapulas were positioned on the back of its rib cage. Mystery fossil primate E lived in the middle and late Eocene in Europe. It had a postorbital bar very large orbits. and a short snout. Its dentition suggests an insectivorous diet, and its postcrania indicate it did a lot of leaping.
