I missed this on 60 Minutes Sunday (10/5) night. Glad I have a chance to see it now. Amazing! Chaser is being called the smartest dog in the world. It's not that Chaser can do all kinds of tricks, it's that the border collie is actually learning. He can can identify over a thousand toys.

According to the CBS News segment:

Brian Hare, an evolutionary anthropologist at Duke University, believes Chaser is the most important dog in the history of modern scientific research.
