How Smart Are Animals?

How Smart is Fido? That dog who sits at the edge of your bed and waits for you to utter the magic words: “let’s go for a walk.” How smart is that fish swimming by you in the sea? It is well known that the chimpanzee is our closest living relative from a genetic point of view. But, are they the second smartest creatures on earth? Or, is it the dolphin? This documentary looks at some interesting examples. There’s a dog who can understand more than 1,000 words. A mollusk who can bring back shrimp from a closed jar. A dolphin who can understand written language.
Watch How Smart Are Animals? on PBS. See more from NOVA scienceNOW.
