476 PROGRESS OF SCIENCE IN THE CENTURY. 



teristics of man, — language, reason, morality, — every 

 fair-minded enquirer must admit that it is difficult 

 to disclose the factors which evoked them, but that is 

 hardly an argument against deciding that their mode 

 of origin was evolutionary. 



Although the structural resemblances between man 

 and the anthropoid apes are numerous and plain, 

 no one now dreams of arguing that man is descended 

 from any existing form. Different living forms ap- 

 proach man in different ways. At what point the 

 human stock diverged from the Simian remains quite 

 obscure; no certain intermediate links are as yet 

 known, — though some of the oldest known human 

 skulls are primitive in some of their features. 



'Nor can it be ignored, that, as regards various 

 structural characters, some experts have found it 

 necessary to look for man's ancestry even deeper than 

 in the monkey race, — down to the Prosimiae or Lemu- 

 roids.* 



Dr. E. Dubois' discovery of remains at Trinil 

 in Java (which he calls Pithecanthropus erectus) is 

 interesting and valuable, but they are fragmentary 

 (skull-cap and femur), and experts differ greatly in 

 their interpretation of them. The Trinil femur 

 seems to have been that of a being who stood up- 

 right; the capacity of the skull (inferred from the 

 cap) was greater than that of any known anthropoid 

 ape, but inferior to that of human skulls of low type 

 belonging to the Stone Age. The remains are either 

 those of a missing link or of a low and ancient type 

 of man. 



"The antiquity of the human race is much greater 

 than was previously supposed; we must go back to the
