HUMAN LIFE 



ogy and geology than students of human- 

 isties. Man for them is an animal whose 

 evolutionary history is to be traced, 

 as that of other animals is traced, by 

 finding and studying his fossils or the 

 preserved products of his handiwork, or 

 those of his forebears, in their relation to 

 successive geologic formations, hence to 

 time. It is to the paleontologist and 

 historical anthropologist, therefore, that 

 we look for facts concerning the very 

 earliest days of man s existence. How 

 far back in geologic time, how long ago as 

 estimated in years and centuries, does 

 man seem to have lived on this earth? 

 Where did he live? Does he first appear 

 as scattered over all the land surface of 

 the globe, as he now is, or was he originally 

 limited to a certain part or parts of it? 

 What sort of man was he in those first 

 man days? What of his body? What of 

 his habits, his culture, his relation as 

 individual to others of his kind? Oh, 

 there are many crowding questions we 

 wish to put to the student of prehistoric
