Exaptation in the Co-evolution of Technology and Mind: New Perspectives from Some Old Literature

Abstract

The term exaptation, describing the phenomenon that an existing trait or tool proves to be of new adaptive value in a new context, is flourishing in recent literature from cultural evolution and cognitive archaeology. Yet there also exists an older literature from the nineteenth and twentieth centuries which studied more or less systematically the phenomenon of “change of function” in culture and tool use. Michel Foucault and Ludwig Noiré, who devoted themselves to the history of social institutions and material tools, respectively, occupy an important place among them. This article offers a brief overview of this literature and attempts to show that it provided ideas that remain relevant to current approaches to cognitive archaeology, in particular regarding attempts to understand the impact of technological evolution on the human mind.
