There was a linguist who brought up those five key attributes of human language as being crucial, I can’t find his name right now :(
And I did not say that animals don’t use language. Or did I?
What I mean to say is that there is a dramatic difference in expressive power, in particular in being able to convey a plan of action. Animal language can convey “there is a tiger south-south-west 15 meters, run for your life”. But it can’t express “if there is a tiger run left, if there are two tigers run to the right” unless the animals have previously encountered that situation and survived unwittingly executing this plan of action.
To me this is akin to the difference between Turing complete and subturing languages, in that the expresssive power is so very different.
