Abstract

Seen from the perspective of a biologist, the issue of the origin of language contains an inherent ambiguity. On the one hand, one might think to explore the cognitive features or even the anatomical structures related to communication through the peculiar medium called verbal language, a characteristic property emergent among the Homo sapiens. On the other hand, if one decides to restrict oneself to the formal definition of language as a system of signs for encoding information, then, the human‐specific nature of language becomes less convincing and the temptation to look into non ‐ human languages allows a provocative question. Was human verbal language an invention or a discovery? In the following two biologists informally discuss about the concept of non‐ verbal biological languages.
