In North America the black bear was seen by Hearne 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 aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale.
-Darwin
B) even if you think he was seriously proposing that, "as monstrous as a whale" is not the same as "is a whale", unless you're going to explain how this is a whale too:
Boeing 737, about the same length as a blue whale - "as monstrous as a whale".
Coulter said, and I quote, "They [evolutionists] say the whale "evolved" when a bear fell in the ocean". No, we don't say that.
