A Concept of Death in Genus Pan: Implications for Human Evolution

Abstract

An understanding of what death and dying entail is termed a concept of death (CoD), and the human CoD is often viewed as one of the characteristics that distinguishes our species. In this research, I identified an analogous understanding of death and dying in our closest living relatives—genus Pan. Linguistic frameworks designed for studying the CoD in human children look for evidence of understanding of several facets of death. I adapted these frameworks for the non-verbal Pan species, systematically analysing written and video recordings of chimpanzee and bonobo behaviours surrounding death within these new behavioural frameworks. I identified compelling evidence for the comprehension of several aspects of death, and thus for the presence of a human-like CoD in chimpanzees and bonobos. This has implications for our own evolutionary story and raises questions about what makes humans ‘human’.
