User innovation: a novel framework for studying animal innovation within a comparative context

Abstract

Abstract Much work has been dedicated to defining and describing animal innovation. Despite this, efforts to compare human and animal innovation have been hindered by perceived fundamental differences between how, and why, humans and animals innovate. Furthermore, there is not a useful framework for comparisons across different taxa. Here, we provide an overview of the current understanding of human ‘user’ innovation, provide some examples of user innovation, and highlight the parallels between animal innovation and user innovation by humans. User innovation, put simply, is the process by which people invent to satisfy their own needs, not necessarily with the aim of distributing their invention, or marketing it for profit. Thus, it is much more closely aligned to the manner in which nonhuman animals innovate. Our intention is that this discussion will help to re-frame how we consider animal innovation and foster more direct comparisons between human and animal innovation, while propagating new avenues for research, both experimental and observational.
