Over the last several decades Ellen Dissanayake has developed an evolutionary theory of art that views all art as having evolved for the function of promoting group cohesion. This theory is not without its critics, yet it has received little empirical attention. In this article I propose a more modest formulation of Dissanayake’s hypothesis and proceed to test it using a cross-cultural analysis. I rely on the ethnographic databases of the electronic Human Relations Area Files as well as the Standard (...) Cross-Cultural Sample to compare proxies for group cohesion with measures of ritual art, a subset of art that I theoretically define. While my results cannot decisively prove or disprove Dissanayake’s hypothesis, they do lend empirical support to her views. This is promising not only for her views but for outlining ways of empirically testing other views in evolutionary aesthetics. (shrink)
