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

Transformations in the “behavioral innovativeness” of species —broadly, the capacity to generate new or novel behaviors — 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 is the absence of a good measure of behavioral 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 behavioral innovation.
