In the last years evolutionary biology made great progress. It is most interest-ing that recently studies consider not only the physical evolution but also the cognitive one. Here it is for example by now widely accepted to assume a co-evolution of brain and language. This would mean that linguistic structures are dispositioned within the human brain – and therefore intercultural. Of course one firstly thinks of Chomsky’s generative grammar. But research goes beyond that and discusses the biological foundations of structuring knowledge in general. Passing on knowledge by narration is one of many ex-amples. This article discusses whether evolutionary biology can provide ideas and concepts to naturally designed interfaces.
