Teaching about language in a university setting, we often talk about various forms of evidence for language-like communication among animals.

As I tell students, I would bet that within our lifetimes, as research continues and our instrumentation becomes better at detecting non-human communication means, we'll finally be able to detect and decode 'language' in a non-human animal which is sophisticated and rich enough as to be impossible to handwave away.

But what I keep to myself is that this kind of discovery, and the cross-species conversations it would prompt, has the potential to change the course of the dialogue on animal rights and what it means to be 'human'. But I suspect it will wind up being largely buried outside of certain academic and spiritual communities, mostly because I don't think parts of our society could handle learning the bovine words for 'slaughterhouse' or 'mourning'.
