Researchers examine the ethnographic record, sampling 82 hunter gatherer societies from the HRAF World Cultures database, for cross-cultural patterns of archaeological evidence of knowledge of astronomy and constellations. Surveying the data, researchers identified many patterns in the upper paleolithic, noting the importance of further examination of this topic.

This article hypothesizes that ritual ecstasy was selected for as a way for hunter-gatherers to cope with resource uncertainty by unifying separate groups. Results support this hypothesis and suggest a relationship between resource stress and deities as well as dependence on animals and presence of zoomorphic deities.

A materialist approach is used to study the status of women in hunter-gatherer groups. Techno-ecological factors are tested as predictors of women's status.

This study analyzed fire use in 93 hunter-gatherer groups based on ethnographic texts from eHRAF in order to improve our understanding of early hominin fire use. The researchers collected data on the groups' methods of making fire, the ways they used fire, and when and where they created fires. The study found that some groups either did not know how to make fire using traditional methods or had very few members who knew how to use such methods. The study also found that many groups preferred to preserve fire rather than create it anew, even carrying it between camps. Beyond this, the ways in which fire was created and used varied widely between hunter-gatherer groups. These findings have implications for understanding early pyrotechnology and the interpretation of the presence or absence of fire residues in the Palaeolithic archaeological record. The results suggest that the absence of fire residues may indicate the absence of fire-making knowledge and skills rather than just taphonomic processes, and that the presence of fire residues does not necessarily indicate the ability to manufacture fire.

Previous research into the origins of human violence and warfare has oftentimes been inconclusive and controversial. This paper examines two alternative theories as to the evolution of human violence using archaeological records on sharp force trauma (SFT) and blunt force trauma (BFT). The study is limited to 13 different California ethnolinguistic groups. Researchers find that violence is not predicted by sociopolitical complexity, but rather by environmental productivity. This supports the idea that in contexts of resource scarcity, the perceived benefits to engage in lethal aggression may outweigh perceived costs.
