ABSTRACT
Humans have in the past defined intelligence, culture and society in ways that focus on human abilities and characteristics, assuming that these characteristics are unique to humans. Research over the last few decades has become less anthropocentric, focusing on the evolution of behaviour in human and nonhuman animals. It is now becoming clear that the behaviour and abilities of humans result from the combination and modification of properties found in other animals (including primates) rather than from ‘unique’ properties (see for example, Roth and Dicke, 2005).
