Man's antiquity is to be measured not in 

 centuries but in millennia. It is perhaps 

 150,000 years since he used stone weapons in 

 Europe against mammoth and rhinoceros, 

 hyaena and lion, and these weapons were not 

 the work of novices. No fossil remains of 

 man have been found except in Post-Tertiary 

 (Diluvial) deposits, but there are several 

 reasons for believing that his origin was very 

 much earlier. Thus, for instance, it is cer- 

 tain that he did not arise from any of the 

 known anthropoid apes (gorilla, chimpanzee, 

 orang and gibbon), but from a stock common 

 to them and to him; therefore it is likely that 

 the human stock had diverged before the 

 time when the anthropoid apes are known 

 to have been established as a distinct family, 

 namely, in the Miocene. 



It is possible that man arose as a mutation, 

 as an anthropoid genius in short, but the 

 factors that led to his emergence are all 

 unknown. We must remember, however, 

 that the stock of Primates to which he is 

 zoologically affiliated is marked by great in- 

 telligence, and that we find illustrated amongst 

 them some very significant habits of walking
