MAN AND APE COMPARED

to the chimpanzee, and that both are integral parts 

 of one great scheme of life, designed by the same 

 author, fashioned after the same model, projected 

 upon the same plan, and amenable to the same 

 system of vital economy. Viewing him in the light 

 of his physical nature, so far it is found that he does 

 not materially differ from other animals in the struc- 

 ture of his skeleton and certain concomitants. 



In the vital organs of the two there is perhaps 

 still greater unity of structure, and equal unity of 

 function in all essential details. The difference of 

 structure is only to the extent of making the organ 

 conform to the general plan of the animal, and the 

 difference of function is only one of degree. Since 

 the same characters vary quite as much among men 

 without changing their identity as such, it cannot be 

 sufficient ground to widen the hiatus between man 

 and ape ; in fact, the physical likeness of the two 

 grows stronger as the comparison is extended into 

 more minute and scrutinising details. To the casual 

 observer the general resemblance is apparent, but to 

 the student the unity becomes evident. 



In addition to the facts we have cited, the ape has 

 the same habits of rest and sleep ; lives on the 

 same kind of diet, which is eaten and assimilated in 

 the same manner as with man ; is subject to many 

 of the same diseases which attack the same organs, 

 and affect them in the same way as with man ; he 

 suffers like pains and dies in the same manner as 

 man under like conditions.
