All identity quests forcibly lead us to questioning our origin. What distinguishes us from others that resemble us? What are our first human apomorphic traits? Where lies the initial manifestation of our humanity? And more broadly, how are we, as living beings, propelled toward humanisation? The overall trajectory of hominids is central to those questions. Whereas most of the human sciences are concerned by it, the role of semiotics is to investigate our phono-reality in its biosemiotic (as well as paleosemiotic, archeosemiotic, etc.) aspects. This article seeks to examine various elements that belong to this trajectory. Might we achieve a better understanding of our specific human traits by studying their inimitability? Might humanoïd robotics, which, regardless of its pretentions, is still incapable of reproducing human beings, help us nonetheless in this task? In opposing biosemiosis and robosemiosis, the author treads this path in an effort to determine the most specific human traits and thus uncover how to best reveal the unequaled Apex of our humanity.
