Putty-Nosed Monkeys use sentences

[Ray Newland]

Some researchers have found what appears to be syntax usage in non-
humans. Some putty-nosed monkeys are using calls normally reserved
for warning their peers of predators when no such predators are
present (something I had always believed to be somewhat taboo amongst
primates). Moreover, they are using them in sequence in indicate
something unrelated to those predators and their peers are presumably
taking meaning from this abstraction.

This is a cool finding.
