342 THE LIMITS OF NATURAL SELECTION 
nians, the Digger Indians of North America, or the 
natives of Fuegia, pass their lives so as to require 
the exercise of few faculties not possessed in an equal 
degree by many animals. In the mode of capture of 
game or fish, they by no means surpass the ingenuity 
or forethought of the jaguar, who drops saliva into 
the water, and seizes the fish as they come to eat it; 
or of wolves and jackals, who hunt in packs; or of 
the fox, who buries his surplus food till he requires 
it. The sentinels placed by antelopes and by monkeys, 
and the various modes of building adopted by field 
mice and beavers, as well as the sleeping place of the 
orang-utan, and the tree-shelter of some of the Afri- 
can ‘anthropoid apes, may well be compared with the 
amount of care and forethought bestowed by many 
savages in similar circumstances. His possession of 
free and perfect hands, not required for locomotion, 
enable man to form and use weapons and implements 
which are beyond the physical powers of brutes; but 
having done this, he certainly does not exhibit more 
mind in using them than do many lower animals. 
What is there in the life of the savage, but the satisfy- 
ing of the cravings of appetite in the simplest and 
easiest way? What thoughts, ideas, or actions are 
there, that raise him many grades above the elephant 
or the ape? Yet he possesses, as we have seen, a 
brain vastly superior to theirs in size and complexity; 
and this brain gives him, in an undeveloped state, 
faculties which he never requires to use. And if this 
is true of existing savages, how much more true must
