Niche construction theory (NCT) is a relatively new development within evolutionary biology, but one that has important implications for many adjacent fields of research, including the human sciences. Here, we present a broad overview of NCT and discuss its application to archaeology. We begin by laying out the basic arguments of NCT, including a historical overview, focusing on how it affects understanding of human behavior and evolution. We then consider how NCT can be used to inform empirical research and how it might profitably be applied in archaeology, using as a case study the origins of agriculture. We suggest that the unrivaled potency of human niche construction, compared with that of other species, means that archaeologists need not be mere consumers of biological insights but can become important contributors to evolutionary theory.
