THE EVOLUTION OF MAN *59 



Man is hardly as yet subject to Malthus' law, for while he is 

 increasing more rapidly than any other animal, owing largely to the 

 care of the young which makes the expectation of life of the new-born 

 relatively very high, his migratory ability, but above all his intelli- 

 gence, save him from the application of the law. A single new dis- 

 covery such as that of electricity may increase his food supply and 

 other life necessities several fold. His future evolution, in so far as 

 it is progressive, will be mental and spiritual rather than physical, and 

 as such will be the logical conclusion of the marvelous results of 

 organic evolution. 



Sinanlhropus pekinensis 



A remarkable new discovery has come to light during the last few 

 years and deserves to be added to the foregoing account by Professor 

 Lull: the discovery of Pekin man, Sinanlhropus pekinensis. Next to 

 Pithecanthropus in the fossil series of primitive man, and only a stage 

 more advanced, is this newly discovered genus. A few years ago, Pro- 

 fessor Davidson Black found some fossil teeth near Pekin, China, 

 which, though distinctively human, were different enough from any 

 others known to be assigned to a new genus of man. Search for further 

 remains in the same neighborhood brought to light two lower jaws 

 containing the kind of teeth discovered by Black. The investigation 

 was climaxed a little later when the Chinese anthropologist, W. C. Pei, 

 unearthed in the same neighborhood a complete cranium. At last 

 reports, collectors had brought in parts of skeletons of at least ten indi- 

 viduals. While Sinanlhropus is more like Pithecanthropus than any 

 other extinct genus of man, it is a more advanced type and helps ma- 

 terially to bridge the gap between Pithecanthropus and the higher 

 human genera. At this writing further details about this new genus 

 would be inappropriate, since investigations upon it are still in progress.
