Why shouldn't whales learn? Do you really think that learning is confined to humans? That there is an unbridgeable gulf between us and lower creation that sets us specially apart?

Foxes learn- they have adapted their habitat from the countryside to towns within the last hundred years- far too fast for the change to have come about by genetic mutation and natural selection. The notorious blue tit milk bottle heist can only have come about since the introduction of milk bottles. Or are you saying that blue tits are genetically predisposed (pre- adapted) to stealing milk?
