Degreecoordinates, Shared traits of the Hominini (humans, bonobos and chimpanzees), 2015
The work presents a catalog of questions about traits of our behaviour and anatomy. As it is, the same answers are possible for all members of what biologists call ‘Hominini’ – a ‘tribe’ of apes that includes humans, bonobos and chimpanzees. Thus, possible responses do not define differences between these species, challenging the idea that humans are ‘unique’. Instead, the mixture of answers highlights distinctions and similarities between individual members of the Hominini, never mind their species. Our replies hence reveal personal cultural boundaries that we share with some human or non-human apes, but not others.
“Differences are of degree, not of kind” (Charles Darwin).
