A video by Nature  on the evolution of the whale.  http://www.youtube.com/watch?v=lx079oEgKKs

Compare how a dolphin swims (https://www.youtube.com/watch?v=-hXTYe58g34) to how a dog runs (https://www.youtube.com/watch?v=_caOk6lycb0). Now compare a dolphin to a shark (https://www.youtube.com/watch?v=d-1xU0VfJ-g). Which does it look like? Evolution!
