A model for the development of counting systems is tested. The hypothesis presented predicts that unpredictable climate conditions result in inconsistent food supply which leads to the need for food storage and, thus, a system to account for the stored food. Results strongly support this hypothesis.

In order to examine the development of lexical numbers (LN), the linguistic rules which allow for expression of high quantities and complex numerical operations, Overmann examines LN's association with grammatical number (GN), an expression of quantity based on the distinction between singular and multiple entities. LN and GN generally occur together, but LN is also found in a significant number of societies lacking GN, indicating that the two are both independent and related. A subsequent analysis of geographic distribution of LNs and GN indicates that LN may emerge prior to GN as a result of the interaction of numerosity (the ability to perceive different quantities) with tactile engagement with material structures (e.g. tools, the hand) which may subsequently lead to the development of GN. Overmann examines the theoretical implications of and explanations for these findings, and discusses how the present study contributes to the knowledge of linguistic frameworks.

This paper examines the relationship between the complexity of a society's material culture and its development of cognitive technologies for numeration and timekeeping. The researcher claims that the resulting positive correlation between these variables as support for a theory of material culture as 'scaffolding' for number concepts, providing tangible, shareable, manipulable forms for abstract numerical constructions.

This study focuses on the factors associated with the development and persistence of an ideology of male supremacy. Authors identify several realms of culture that show a clear male preference and suggest that warfare is the most significant cause of the male supremacy complex in preindustrial societies. Authors hypothesize that warfare will be positively related to female infanticide. Results support this hypothesis. Another hypothesis relating diet to warfare and infanticide is provided, but not tested.

The association between hunting and sign language is examined. It is hypothesized that sign language develops as a form of nonverbal communication to aid hunters in the coordinated stalking of game. Ethnographic evidence supports this hypothesis. A second hypothesis is also tested concerning the relationship between population size and non-verbal communication, however sampling procedures provided an inadequate test of this hypothesis.
