In his Origin of Species, Darwin notes a case of a black bear swimming for hours with its mouth agape, catching aquatic insects much as a whale might feed. "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," he speculated.
The ridicule and attacks engendered by this passage grew to such a pitch that Darwin pared it down and then deleted it altogether in later editions.
Although Darwin got the particulars wrong, his swimming-bear scenario was not far off the mark. Modern molecular biologists say that they now have the unassailable evidence to track whales' origins among four-legged mammals.

Regardless, using darwin to attack evolution is the height of dishonesty. It is like pointing to a flaw in the kitty-hawk to argue against the theory of flight.
