NEXT STEP IN EVOLUTION 



velously and clearly retells the 

 history of the evolution of the 

 physical nature of the human race 

 from the one-celled moneron to 

 the billion-celled man. For the 

 embryo of the child is a historic 

 map, done in flesh and blood, of 

 the evolution of man, of the forms 

 he has assumed, broadly speaking, 

 as he climbed nature's stairway.* 

 But more than man's physical 

 nature was evolved. 



* Romanes, in "Darwin and After 

 Darwin," chap, iv., says that the em- 

 bryo is a resume or recapitulation of 

 the successive phases through which 

 the being has been developed with cx- 

 planable omissions. On p. 102 he tells 

 of the young salamander that is so 

 complete in its gills shortly before birth 

 that if it is removed from the womb 

 and placed in water it will be able to 

 live, breathing like a fish through its 

 gills.
