Noam Chomsky talks about this in his books on language, but he draws a line between the kind of communication that is done with body language, gestures etc and human language, asserting that simply adding complexity to gestures and sounds over time through reinforcement (which was the dominant theory of language's evolution for a long time) is not a sufficient mechanism to explain how human language arose and how it is acquired by children today. He argues that true "language" is only possible with a specific adaptation unique to humans (possibly an earlier hominid), and that the evidence for this is that even animals with relatively complex forms of communication, like chimpanzees and apes, cannot be taught simple concepts like grammar. "Me eat" versus "eat me", for example, is a distinction that Koko the gorilla never figured out.
That is not to say that "human language" can't be done with gestures, for example signs languages have existed for basically all human history - but every sign language has grammar and other markers that set it apart from simpler gestures and indicate that something more fundamental than repetition and increasing complexity over time is necessary for their creation.
Interesting, I would say to this that Grammar is the exact sort of complexity that will arise out of the necessity for more and more distinctions. Flipping "eat me" and "me eat" became, at some point, important enough that the relation between a sign and time became important. That is a way that grammar can quickly grow out of "no grammar"
