summaryIs human language unique among primate systems of communication in exhibiting syntax and recursion? The recursive, hierarchical embedding of language units minimally requires a ‘context free grammar’. This is more complex than the finite state grammars thought to be sufficient to specify the structure of non-human communication signals. Animals seem unable of learning and discriminating strings of a context free grammar from those formed by simpler rules. Here we show that spontaneous combinatory calls of wild muriquis (Brachyteles hypoxanthus), a New World monkey, exhibit a grammar which is not only context-free but also context-sensitive. Thus, the capacity produce recursive, self-embedded grammars is not uniquely human. This finding suggests that some essential mental processes that make human language are shared with humans’ non-speaking cousins.
