Tool Use Beyond Humans

The definition of tool use has long been debated, especially beyond humans. Recent work argues that the phenomena included within tool use are so broad and varied that there is little hope of using the category for scientific generalizations, explanations, and predictions about the evolution, ecology, and psychology of tool users. One response to this argument has been the development of tooling as a replacement for tool use. In this article, we analyze the tool use and tooling frameworks. Identifying advantages and limitations in each, we offer a synthetic approach that suggests promising avenues for future research.
