Description

Costly signaling theory (CST) explains a variety of elaborate behavioral displays as a consequence of competition over resources when the risk of direct conflict is high. Within an archaeological context, monumental architecture is potentially explained as a facet of costly signaling between individuals and groups. On Rapa Nui, CST offers an explanation for the construction of labor-intensive monuments including massive statues (moai) and ceremonial platforms (ahu). Using hypotheses derived from CST and spatial data about the distribution of archaeological features, the degree to which CST accounts for the investment in prehistoric monumental architecture on Rapu Nui is evaluated.
