"It is an interesting fact that on oceanic islands far removed from 

 continents only those forms of life are found which could be borne to them 

 by wind or wave. Only such birds as can be carried long distances by 

 strong gales appear. The fauna of such islands contain no mammals except 

 bats, and in every instance the life, both of plant and animal, is similar to 

 that of the nearest mainland, yet differs from it in having distinct species. 

 If special creation accounts for those forms, why are they not identical with 

 those of the mainland? There is no answer. But evolution affords a simple 

 and inevitable explanation. And if we admit that the original forms of 

 life come from the mainland, and have since changed into new species, then 

 the case of evolution is established." — F. L. Darrow, Through Science to
