Step 1: Position the lamp so it is above the doll and facing directly downward (as if the sun were directly overhead). Step 2: Position the doll so that it is on all fours under the lamp, similar to a baboon wandering the open savanna. Note the amount of sun exposure the doll receives in this position. Step 3: Position the doll so that it is standing on two legs under the lamp, similar to a human wandering the open savanna. Note the amount of sun exposure the doll receives in this position. Step 4: Answer the following discussion questions: 1. In which position did the doll have the least sun exposure?
2. Why might having less sun exposure be an advantage in a warm environment?
3. In which position do you think the doll has the most exposure to wind and air circulation?
4. Why might having more exposure to the wind be an advantage in a warm environment?

5. Based on this test, do you think the thermoregulation hypothesis might provide a valid explanation for the evolution of bipedalism? Is it challenged by the pre-australopithecine finds?
Critical Thinking Questions 1. This question may be completed independently or as a group exercise. Describe the three different types of bipedalism. For each one, be sure to discuss the frequency of bipedal locomotion, describe the extent of bipedal adaptations, provide at least one sample primate who practices this type of bipedalism, and describe why the sample primate uses this form of bipedalism.
