You assert that animals "use" reason. Alternatively, one might say that they use "instinct" -- "progammed" into animals by the same Source that "programmed" man for reason.
That animals learn language is a completely unfounded canard. After all this time, I think we could expect to have some poetry out of the higher apes if that were the case.
Tool using behavior by animals appears to be of a rather low-level kind. There may be a crude type of learning involved; I don't know. But for the most part it seems to be the sort of thing that a parent animal transmits to its young by example, not by reasoning. As far as I know, there is no animal species which has yet managed to construct, say, an Eiffel Tower.
Pack hunting for certain species can be quite easily explained as an instinctive, and not a learned behavior.
I wonder which of us is spinning the more egregious "myth" here.
BTW, you seem to be using that term with a certain amount of disdain or contempt. Am I right about that?
