To determine the correct answer to this question, we need to understand the characteristics of both Chinese premoderns and erectus. Let's examine each option:
A. Extreme post orbital construction and sagittal crests: These traits are commonly associated with erectus. Post orbital construction refers to the shape and structure of the eye sockets, while sagittal crests are ridge-like structures on the top of the skull.
B. Projecting canines and diastemata: Projecting canines are prominent, protruding canine teeth, while diastemata are gaps between teeth. While projecting canines are a typical feature of erectus, diastemata are not specifically mentioned as a characteristic.
C. Sagittal ridges and flattened nasal bones: Sagittal ridges are similar to sagittal crests, mentioned in option A, and refer to the ridge-like structures on top of the skull. Flattened nasal bones refer to a relatively flat structure of the nose, which is a trait found in erectus.
Considering all of the above points, it appears that all the options (A, B, and C) include characteristics associated with erectus. Therefore, the correct answer is D. All of the above.
