Abstract
In the field of ethological studies many efforts of researchers are devoted to understand how animals communicate and what is the role of communication from an evolutionary and functional point of view. Progress in this area might also have an impact on our understanding of human communication since animal and human communication systems share several features (Hauser, 1996). The social function played by human language, for instance, is one of the first traits that allows us to place language in the same evolutionary field as other animal communication systems. Moreover, recently also the idea of the uniqueness of human language regarding the representational fashion of the knowledge and the compositionality of signals is challenged by new findings in primate research that indicate that, in baboons, knowledge is representational, based on properties that have discrete values and, from a certain point of view, propositional (Seyfarth et al., 2005).
