Abstract

In this paper we introduce the notion of historical evidence - the ability to replicate biologically realistic evolutionary scenarios - for hypothesised mechanisms for control of sensorimotor behaviour. We apply the idea to the phonotaxis mechanism proposed by Webb and her collaborators to account for the abilities of Gryllus bimaculatus. To do this, we tested whether the proposed control mechanism, when implemented in a robot model of the animal, could account for evolutionary adaptations observed in the natural system. We describe and discuss the experiment and its results, but start by explaining the methodology used, which is an extension of Webb's existing methodology for obtaining behavioural evidence for a hypothesised mechanism. We conclude there is historical evidence for the neural control mechanism investigated.
