THE EVOLUTION OF MAN 



with such skulls has once existed, and the dis- 

 coveries at Spy and Krapina have shown at the 

 same time to what period that man belonged. 

 They were found together with the bones of the 

 mammoth and cave bear of exactly the same age. 

 They were therefore remains of "Ice-age" men, 

 and these ice-age men still showed this strange 

 divergence from the present living type of 

 "man." 



Now, let us imagine that these variations con- 

 tinued far into the more primitive period. The 

 traces of civilization, as we have seen, finally 

 disappear altogether. Man himself, if present 

 in those very primitive periods, would not have 

 been advanced far enough to fashion the crudest 

 weapons out of flint stone. And we may log- 

 ically draw conclusions from this lack of ability 

 as to his physical constitution. The man of the 

 Ice-age was able to fashion weapons from flint- 

 stones, and yet he was far behind us in the struc- 

 ture of his skull. How far behind, then, in the 

 structure of his skull, would be a man without 

 knowledge of flint stone tools? 



The line of research here absolutely dissolves 

 into nothing. Man diverges more and more from 

 the present type of human beings. He finally 

 varies to an extent which makes him absolutely
