Mapping Out the Landscape: A Multi-dimensional Approach to Behavioural Innovation


 Transformations in the “behavioural innovativeness” of species—broadly, the capacity to generate new or novel behaviours—have been associated with significant evolutionary shifts in cognition by both philosophers and scientists. Whilst intuitively and theoretically appealing, this assumption lacks strong empirical support. One barrier being the absence of a good measure of behavioural innovation. This paper offers a solution to this problem by breaking down innovation into its components and presenting a novel multi-dimensional framework for characterising and comparing putative cases of behavioural innovation.
