AS THE BIOLOGIST SEES IT 



man, too many to enumerate. And we 

 really hang breathless on his answers. 

 But before we listen to any of the an- 

 swers let us note that the anthropologist 

 in his attempts to satisfy his and our 

 curiosity about primitive man has a 

 second string to his bow in addition to 

 that provided him primarily by the 

 paleontologist. He recognizes in his 

 study of the man-group, just as the 

 general biologist does in his study of any 

 group of animals or plants, that the 

 present existing members of his group 

 are not all of equal evolutionary advance- 

 ment or chronology. There are always 

 some of a type less advanced or special- 

 ized, and some of types more advanced. 

 The less advanced are usually presumed 

 to be older in their evolutionary origin 

 than the more advanced, so that although 

 they all live now side by side and at the 

 same time, some may be looked on as in a 

 form or stage of greater primitiveness or 

 antiquity as compared with others. This 

 is indeed quite true of the various living
