No, really.

The researchers . . . tested monkeys by showing them side-by-side video images of another monkey making two sounds, while playing a soundtrack of just one of the sounds. . . . [T]he test monkeys were able to match the sound with the correct video image.

I’m sure it won’t make a dent in the idea that speech is uniquely human and qualitatively different from all other forms of animal behavior. But it’s a start.

(Now my question is, how do you get a “friendly coo” from a monkey trussed up in a “standard primate restraint chair”?)
