In "The Urban Revolution" (1950), V. Gordan Childe hypothesized ten traits of civilization: urban centers, occupational specialization, monumental buildings, taxation by and/or tribute to elite, isolation of ruling group(s), writing, art, long-distance trade, social solidarity reinforced through common ideologies, and state formation. The author of this study analyzes these traits, and in particular, the presence of written language, with data from two different databases, one ethnographic and one archaeological. He finds that written language is highly correlated with the other traits of civilization as hypothesized by V. Gordan Childe.

This article discusses the reasons behind advances in craft specialization particularly why there is a relationship between advances in craft specialization and the emergence of powerful elites. Hypothesis tests focused on political centralization.

This article tests for universal patterns in cultural evolution by Guttman scaling on two different worldwide samples of archaeological traditions and on well-known archaeological sequences. The evidence is generally consistent with universal evolutionary sequences.

This study examines the influence of the "child-adult" conflict on the frequency of drunkenness in a culture. In particular, the author examines the socio-psychological factors that can induce a child-adult conflict, claiming that this conflict may be more common when mothers are the primary dispensers of rewards.

This study tests the relationship between menstrual taboos and castration anxiety. The author posits that the extensiveness of menstrual taboos is determined by the average castration anxiety. Using various measures of castration anxiety, the author finds significant support for this hypothesis.

This article tests Rushton's hypothesis that there is a relationship between "race" (Negroid, Caucasoid, and Mongoloid) and various aspects of behavior. Results do not support this hypothesis.

This article stresses the use of multivariate analysis to study the emergence of states. The authors first discuss how social inequality, population density, and trade affect state development. Next, they turn to a time series regression to formally examine social stratification, urbanization, technological specialization as predictors of political integration. Finally, economic vulnerability and scalar stress are considered as possible underlying factors in the emergence of states.

This article retests several hypotheses from Swanson’s (1960) study on the origins of religious belief. The author finds support for an association between high gods and large communities, multiple levels of political hierarchy, and social differentiation. No support is found for Swanson’s other hypotheses concerning polytheism, ancestral spirits, reincarnation, the soul, witchcraft, and morality and their relations to social, political, and economic variables.

This study tests the hypotheses that games of strategy will be more prevalent in societies where political power is based on a "network strategy" and that network societies place more value on the enculturation of obedience in children. Both hypotheses are supported.

This article employs archaeoethnology to investigate possible patterns of synchronous population growth among cities of the prehistoric New World. The author finds a pattern of settlement synchrony distinct from a pattern found in the prehistoric Old World, suggesting that global climate change may not be a key factor in understanding settlement synchrony. Macroregional political and economic processes such as long-distance trade are offered as partial explanations of settlement synchrony in the New World.
