THE DECIDUOUS DENTITION

 that the lower first milk molar was less molariform and the 

 second possessed an occlusal surface approaching more nearly 

 in breadth the crown itself while the hypoconulid was more 

 axial in position than is the case today. We cannot say that 

 the Pfedmost mandible is of unmixed strain. Though probably 

 of primitive Homo sapiens stock there may be in it some ad- 

 mixture of Neandertaloid blood. However this may be the

 of the modern milk dentition.

 Walkhoff.) A less specialized milk dentition than that of today. The teeth present 

 are the first and second deciduous molars and the first permanent molar. 



"We must now examine the deciduous teeth of the Anthropoids 

 (Figs. 88-91} and note if we can obtain from these some indica- 

 tion of what our milk dentition used to be. In doing this it 

 is essential that we should bear in mind the early divergence 

 of the human and Anthropoid lines. Whereas our own ances- 

 tors early became cursorial and predaceous and therefore . de- 

 veloped a tendency rather toward a carnivorous and later a 

 grain diet, the Anthropoids, especially the Orang, progressed 

 toward a completely frugivorous diet. 



As in the case of Man we will pass over the incisors with the 

 simple statement that in the Anthropoids also we find these
