ABSTRACT
This chapter explores connections between two central features of a niche constructive account of practices: treating individual performances within a practice as taking up bodily postures and treating moral/political normativity as constituted within practices. It deals with an initial presentation of a niche constructive conception and shows how this conception enables fine-grained accounts of practical performances as patterns of interaction and interdependence among these bodily postures and the environmental affordances and occlusions. The chapter explores how discursive niche construction accounts for distinctive forms of normativity as a biological phenomenon within the human lineage. A niche constructive account seeks to explain the specific forms taken by practices, and the content, authority, and normative force of their normative accountability, as patterns of ongoing biological co-evolution. Recognizing the evolutionary novelty of practices and their two-dimensional normativity provides no aid or comfort to human exceptionalism or anthropocentrism.
