Since the Upper Paleolithic, there has been a reduction in the robusticity of moderns. Here, the subject is the change in the size, shape and volume of the orbits which seems to be associated with this, in Australia, North Africa and East Asia. A reduction in facial height and prognathism is accompanied by an increase in the height of the orbit, but a decrease in its width.

A comparison is made between the Aborigines and the Tohoku Japanese, because they represent the differences in the average facial proportions, between early Neolithic and modern Chinese.

It is found, that reducing the prognathy and the supraorbital breadth, and a tendency to brachycephaly, reduce the length and breadth of the orbital cavity.
