Apes like us, confessions of a primatologist

Deutsche Version



People of all walks of life readily distinguish “humans” from “animals”. The dichotomy not only reflects the common-sense approach of lay-people, but also a deep-rooted intellectual tendency of many philosophers and theologians of various creeds as well as social and natural scientists. The man-animal gap, seemingly obvious and unbridgeable, has been slowly but steadily eroded with the advent and subsequent elaboration of the theory of evolution. Traits once thought to be unique to humans have become fuzzy, in particular due to naturalistic studies of Great Apes (chimpanzee, bonobo, gorilla, orang-utan). Thus, not only are humans increasingly zoomorphised, but other animals are increasingly anthropomorphised. Profound gradualist approaches are now established in fields such as cognitive psychology (e.g., with respect to paradigms such as theory of mind, referential communication), technology (manufacturing and use of tools, including planning into the future; self-medication through ingestion of carefully selected plants) and cultural studies (behavioural diversity between populations of the same species). The mental worlds of apes are thus very similar to ours. Apes should therefore be regarded as persons, and our own genus should be enlarged to include chimpanzees as Homo troglodytes. Volker Sommer illustrates these controversial positions with findings from his own field-work on African apes.
