I did not even know that modern whales evolved from animals that had evolved to live on land, doing an evolutionary U turn back to a watery life.. I guess I just assumed that since life started in the sea, the whale was a creature who just remained there. Also, it was amazing just how much variety there was along the evolutionary path to the whales that made Nantucket rich.
