Settled communities worldwide are shaped by the conceptual metaphor, SOCIAL DISTANCE IS PHYSICAL DISTANCE. People build their houses so they are near those they are close to socially-which is usually their immediate kin-unless confounded by other factors. This metaphor is, at core, a neural connection, linking neural networks underlying the concept of DISTANCE with social categories. This connection forms in the brains of young children, under conditions found in all human societies, and should therefore operate universally. This article suggests how this metaphor can be used to reconstruct immediate social connections from the layouts of small settlements. It illustrates this by predicting the social structure of Kireyka (Darfur) from archaeologically visible materials, then compares these predictions with reported genealogies. Over three quarters of predicted social clusters are wholly or largely correct, despite competition from other concepts, as well as constraints of space, architecture, and topography. Other case studies suggest that there is no upper limit to the size of communities which may be structured by this metaphor, and that social relations may organise communities for generations.
