No, we don't determine the boundaries of communication, either way. It's
also a error to assume that all sound produced is communication.
For instance, a ciliated protozoa makes a standard beating pattern with
the cilia. This will produce sound vibrations. Who would you say that's
communicating too?
Many sound signatures are a result of evolution for a entirely different
purpose. It's unwise to assume that the evolution was driven by the
sound production.
I believe my position would be that I'm certain that insects make sound
for communication. Sounds made by older, more primitive animals I'm
uncertain that they are for communication. The true answer for first
communicator is not a clear cut black and white thing.
