"Not" is the beginning of language and rational thought. There is not "not" in the pre-verbal animal mind. There is not "not" in emotion. There's aversion and other "negative" emotions, but these are present and positive (in the sense of existing, not being defined by absence.) One is "filled" with disgust, for example. |

In coyotes, it is the absence of pack members in communal howling that triggers hyper-fertility.
In arboreal primates, they tend to have three threat vocalizations (air, tree, ground) and one "no threat" modality.
I don't think it's nearly as clear as you're suggesting. There is even evidence of the use of mathematical 0 in animal cognition and communication.
Formal verbal communication seems more a matter of physical capability than cognitive capacity. Giving animals the ability to speak with sign language (Koko the gorilla, RIP) or buttons (like Bunny the talking dog) has shown that animal cognition isn't nearly as distinct from human cognition as has been thought.
What makes humans special is sophisticated verbalization, opposable thumbs, and being the ultimate endurance/persistence predator.
