A replication of Sipes' (1973) study of the relationship between combative sport and warfare using new codes and a new sample. Although many of the results are weaker than found by Sipes previously, they are still consistent with the culture pattern model as compared with the drive-discharge model.

This article examines sex differences in sports and games of strategy and chance. Results indicated large differences in participation by gender, especially for combat and hunting sports and in patriarchal societies. The possible cross-cultural universality of this trend is discussed.

This book examines the characteristics of warlike and warless foraging societies, as well as the transitional stages that occur when a society becomes warlike. Several predicted correlates of warfare frequency are supported.

This study investigates the presence of feuding, arguing that a solely evolutionary or functional approach misses important inter-societal factors. Results indicate that while fraternal interest groups are associated with feuding, the presence of war and level of political integration also increase the likelihood of feuding.

The authors explore coalitional play fighting (in which teams of at least two play against each other to achieve a goal) across hunter-gatherer societies, with the theory that play of this type may be a mechanism for assessing strength and utility for future defense or warfare. When played against other communities, they propose coalitional play fighting can also serve to gauge strength of potential allies or formidability of potential enemies. In order to test their theories, they predict that, despite the large energy cost and risk of sports associated with coalitional play fighting, these types of games will be widespread in hunter-gatherer societies. In addition, they predict that of those exhibiting coalitional play fighting, many will play against other communities. In support of their hypotheses, they find that 54% of hunter-gatherer societies examined exhibit coalitional play fighting, of which 81% play against other communities.
