Agriculture has been primarily understood from an anthropocentric standpoint with humans being the agents of cultivation and plants the objects of cultivation. This paper regards plants as nonhuman agents in agricultural interactions and presents an alternative perspective by emphasizing that crops had an explicit agenda of making copies of themselves and migrated to new soils using humans as a vehicle for their movement. Rice, wheat, and barley are non-native plants that arrived at the Korean peninsula in prehistory. A number of changes are archaeologically visible since their arrival, such as expansion in site range, increase in community size, shortening of inter-village distances and sedentariness. These changes were immediately beneficial to the reproduction of these crops. This paper demonstrates that the development of prehistoric farming communities is better understood when the changes are envisioned from the plant’s viewpoint and when a discussion on plant materiality is brought into the consideration.
