How old is language? Is it a product only of Homo sapiens, or of other hominids as well? What was the first language like? Or does such a question even make sense?
No one knows the answers to these questions, but that doesn't mean we can't have a discussion about the evolution of language by narrowing down the possibilities with what we know from genetics, neuroscience, anthropology, and linguistics.
This discussion will be prefaced with a short introduction (15 minutes or so) outlining some of the facts needed to help us reach an informed inclusion. From there we will open up the floor so that everyone may contribute their ideas.
