Monkeys can make "comments," researchers say

Interesting... According to this article, researchers analyzed monkey calls
and determined that some of them could only be described as "comments."

These were supposedly the first documented monkey calls that appeared to
make reference to a third party not involved in the vocal exchange. The
monkeys seemed to be making an observation or a comment about what they
were
seeing, the researchers found.
