In the first edition of his book ''[[The Origin of Species by Means of Natural Selection]]'', Darwin claimed that he "can see no difficulty" in race of [[bear]]s enlarging their mouths by eating insects while swimming in the water thus gradually changing into [[whale]]s:     

''"In North America the black bear was seen . . . swimming for hours with widely open mouth, thus catching, like a whale, insects in the water. Even in so extreme a case as this, if the supply of insects were constant, and if better adapted competitors did not already exist in the country, I can see no difficulty in a race of bears being rendered, by natural selection, more and more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale."''<ref>{{cite web |title=Darwin Saw the Whale in the Black Bear |author=John L.
