X08 THE DESCENT OF MAN. [Part I. 



• 



for his breeding has not been controlled, either through 

 methodical or unconscious selection. No race or body of 

 men has oeen so completely subjugated by other men, 

 that certain individuals have been preserved and thus un- 

 consciously selected, from being in some way more useful 

 to their masters. Nor have certain male and female in- 

 dividuals been intentionally picked out and matched, ex- 

 cept in the well-known case of the Prussian grenadiers ; 

 and in this case man obeyed, as might have been expect- 

 ed, the law of methodical selection ; for it is asserted that 

 many tall men were reared in the villages inhabited by 

 the grenadiers with their tall wives. 



If we consider all the races of man, as forming a single 

 species, his range is enormous ; but some separate races, 

 as the Americans and Polynesians, have very wide ranges. 

 It is a well-known law that widely-ranging species are 

 much more variable than species with restricted ranges ; 

 and the variability of man may with more truth be com- 

 pared with that of widely-ranging species, than with that 



of domesticated animals.

Not only does variability appear to be induced in man 

 and the lower animals by the same general causes, but in 

 both the same characters are affected in a closely analo- 

 gous manner. This has been proved in such full detail 

 by Godron and Quatrefages, that I need here only refer 

 to their works. 13 Monstrosities, which graduate into 

 slight variations, are likewise so similar in man and the 

 lower animals, that the same classification and the same 

 terms can be used for both, as may be seen in Isidore 

 Geoffroy St.-Hilaire's great work. 14 This is a necessary
