Zusammenfassung

Using our recent published and unpublished research results in non-model species (from lizards to elephants), I will first discuss the possibility that some specific aspects of skin morphology in vertebrates are emerging from reaction-diffusion (Turing) and mechanical instabilities. I will then suggest that, in ocellated lizards, the superposition of skin geometry (i.e., skin thickness variation due to the presence of skin scales) with the paradigmatic nonlinear microscopic system of interactions among chromatophores causes the underlying Turing-like dynamics to separate into microscopic and mesoscopic spatial scales, the latter generating a cellular automaton that computes a colour pattern. I will then discuss unpublished results that illustrate the importance of tissue growth during skin colour patterning.
