284: THE STRUCTURAL EVIDENCE OF EVOLUTION. 



far as it goes. He retains features wliicli have been obliterated in 

 other persons in the process of evolution. 



In considering the ph3'siognomy of man from an embryological 

 standpoint, we must consider the peculiarities of the infant at 

 birth. The numbers of the following list correspond with those 

 already used (Fig. 53). 



/. As to the General Form. — (1) The head of the infant is rel- 

 atively much larger than in the adult ; (3) the arms are relatively 



longer; (4) there is no waist; 

 (6) the legs, and especially 

 the thighs, are much shorter, 

 //. As to the Surfaces. — 

 (10) The body is covered with 

 fine hair, and that of the 

 head is short. 



///. The Head and Face. 

 — (14) The cerebral part of 

 the skull greatly j^redomi- 

 nates over the facial ; (16) 

 the superciliary ridges are 

 not developed ; (17) the al- 

 veolar borders are not prom- 

 inent ; (20) the malar bones 

 are not prominent ; (21) the 

 nose is without bridge and 

 the cartilages are flat and 

 generally short ; (22) the 

 eyes are larger. 



It is evident that per- 

 sons who present any of the 

 characters cited in the above 

 list are more infantile or em- 

 bryonic in those respects than 

 are others ; and that those who lack them have left them behind 

 in reaching maturity. 



We have now two sets of characters in which men may differ 

 from each other. In the one set the characters are those of monk- 

 eys, in the other they are those of infants. Let us see whether 

 there be any identities in the two lists, i. e., whether there be any 

 of the monkey-like characters which are also infantile. We find 

 the following to be such :
