SPECIES,TEPEES, SCOTTIES,AND JOCKEYS: SELECTED BY CONSEQUENCES

“Ideas are like species: they must evolve.” This claim forms the conceptual core of an engaging book by Jonnie Hughes (2011), On the Origin of Tepees. Hughes asks: If evolution by natural selection explains the origin of the human species, then does selection by consequences also explain the origin of what we humans make and do? This question prompts consideration of three important analogies: between natural selection and artificial selection, between the law of natural selection and the law of effect, and between biological evolution and cultural evolution. These analogies in turn stimulate examination of the notions of purpose, design, and agency. Finally, discussion moves to the selectionism of Darwin and Skinner; although still controversial, this view remains the best way for natural science to understand the origins of adaptive behavior.
