The first part of this course, we have been studying principles of evolutionary continuity in order to shed light on cognitive features that might make us human.  That is, features that might be exclusive to humans and no other species (to the best of our current knowledge).

In light of these concepts, does language qualify as a uniquely human trait? If so, can studying nonhumans teach us anything about language?  How?  If not, then why not? Bring at least three examples (of experimental evidence) from readings and class to inform your answer (note, if you choose to incorporate Project Nim, which you are welcome to do, that would only count as a single source of evidence).
