摘要
While widely acknowledged in the 文化 演化 literature, ecological factors—aspects of the physical environment that affect the way in which 文化 productions evolve—have not been investigated experimentally. Here, we present an experimental investigation of this type of factor by using a 傳播 chain (iterated learning) experiment. We predicted that differences in the distance between identical tools (drums) and in the order in which they are to be used would cause the 演化 of different rhythms. The evidence confirms our predictions and thus provides a proof of concept that ecological factors—here a motor constraint—can influence 文化 productions and that their effects can be experimentally isolated and measured. One noteworthy finding is that ecological factors can on their own lead to more complex rhyth
