In this lab, we learned that australopiths have larger premolars and molars than humans today. We also saw that within the australopith group, the robust species have even larger premolars and molars than their gracile counterparts. To determine these patterns, paleoanthropologists calculate the surface area (in square millimeters) for the last premolar, first molar, and second molar combined. Use the photos in the Lab 15 Exercise Image Library on p. 448 to calculate this information for the mystery fossil specimens. Follow the steps on p. 439 of your lab manual to answer Parts i-iii. You may also complete the chart on p. 440 of your lab manual to help you organize your information. Part i. What is the total surface area in mm2 of Specimen A
