146 SPECIES AND BREEDS.

 the water, can create a Fish, any more than it 

 follows, that, because they can dwarf a tree, or 

 alter its aspect, by stunting its growth in one 

 direction, and forcing it in another, therefore the 

 earth, or the physical conditions connected with 

 their growth, can create a Pine, an Oak, a Birch, 

 or a Maple. 



I confess that, in all the arguments derived 

 from the phenomena of domestication, to prove 

 that animals owe their origin and diversity to the 

 natural action of the conditions under which they 

 live, the conclusion does not seem to me to follow 

 logically from the premises. And the fact that 

 the domesticated animals of all the races of men, 

 equally with the white race, vary among them- 

 selves in the same way, and differ in the same 

 way from the wild Species, makes it still more 

 evident, that domesticated varieties do not ex- 

 plain the origin of Species, except, as I have -said, 

 by showing, that the intelligent will of man can 

 produce effects which physical causes have never 

 been known to produce, and that we must, there- 

 fore, look to some cause outside of Nature, cor- 

 responding in kind to the intelligence of man, 

 though so different in degree, for all the phe- 

 nomena connected with the existence of animals 

 in their wild state. 



So far from attributing these original differ-
