INSTINCT. 79 
which are, even viewed in themselves, the greatest wond- 
ers of creation. The questions insistently call for an an- 
swer: How could these instincts preserve the animal 
when they were still in an incipient, undeveloped state: 
How could they arise through natural selection (which is 
simply accident, of course), at all? Darwin says that 
there are instincts “almost identically the same in ani- 
mals so remote in the scale of Nature, that we cannot 
account for their similarity by inheritance from a com- 
mon progenitor, and consequently must believe that they 
were independently acquired through natural selection.” 
Again he says “Many instincts are so wonderful that 
their development will probably appear to the reader 
a difficulty sufficient to overcome my whole theory.” 
And here, in the vernacular of the day, we would de- 
‘pose that Mr. Darwin “said something.”
