Authors undertook two studies to investigate the natures of work and play cross-culturally in children ages 6-10. The first study investigated potential variables affecting cross-cultural variation in the degree of children's contribution to economic work. The second study investigated the degree to which (and variables affecting why) forms of child's play reflect economic work and/or adult activities across various cultures.

Archaeologists often interpret found portable artifacts (e.g. dolls, miniature weapons) as ritual objects. But it is argued that they might instead reflect children's play activities. This descriptive study analyzes the artifacts and context of children's play using the literature and the ethnographic record of 82 hunter-gatherer societies. Six signs of the presence of children, that might survive in archaeological record are noted, which may suggest that many "ritual activities" are children's activities.

The study is about matrilineal systems, where descent is traced along female lines. Matrilineal systems are relatively rare in human populations, and previous research has discussed the rarity and apparent instability of matriliny. The study aims to study the evolution of descent systems on a worldwide scale. The study tests for significant associations between matriliny and numerous cultural traits that have been theoretically associated with its stability or loss, such as subsistence strategy, animal domestication, mating system, residence pattern, wealth transfer, and property succession. Additionally, by combining genetic and linguistic information to build a global supertree that includes 16 matrilineal populations, the study also performs phylogenetically controlled analyses to assess the patterns of correlated evolution between descent and other traits.

Does belief in moralizing and punitive gods promote sociality between coreligionists who are otherwise strangers? A recent dataset of behavioral economic experiment results and demographic and religious data among eight disparate populations allows the researchers to test their hypothesis of a positive association between deity's perceived interest in human morality and favorability of treatment of outsiders who share a religion. Their findings mostly support this hypothesis, which they suggest lends credibility to a theory in which religion encourages cooperation between large groups of people, and is thus a successful product of cultural evolution.

This article examines proxemic behavior between adults and children in 10 cultures. Data suggests that the older boy-adult male dyad is the most common combination of adult groups and children. Relevant theory on hunting and male-male bonding is discussed.

This article is a quantitative analysis of 592 participants from 8 societies. The study examines a number of theories about what predicts moralistic religions, including life history theory. Findings suggest that there is no evident relationship between these life history predictions and the religious beliefs regarding moralism.

Researchers used population samples from the ALFRED database and the Human Genome Diversity Project (HGDP), in conjunction with 68 populations from the Ethnographic Atlas, in an attempt to identify specific genes involved in human adaptation to environmental stimuli as a result of migration. Specifically, researchers looked at the allele frequencies for four different genes typically associated with varying subsistence forms. These four included the APOE apolipoprotein E gene (lipid transport and regulation of cholesterol), LCT lactase gene (enzyme that decomposes lactose), CCR5 chemokine receptor gene (deletion mutation that decreases immunodeficiency virus propagation), and the ADH1B alcohol dehydrogenase gene (important enzyme for alcohol metabolism). The allele frequencies were then analyzed to distinguish any possible correlation to economic-culture types using a two-sided Spearman Test. Researchers also ran a similar test to analyze allele frequencies and pathogen load, however the majority of the findings were not statistically significant. The findings suggest that there is a definite relationship between the allele frequencies and type of economy of a population.

The purpose of the present article is to "reconstruct the prehistoric evolution and dispersal of Polynesian bark cloth (116)" using cladistic phylogenetic methods on ethnographic data. The author intends to shed light on the evolution of this cultural domain, as well as the settlement patterns and the diversification of Polynesian cultures. No hypotheses are explicitly stated or tested, rather, Larsen is concerned with designing the most accurate and reliable reconstructions in order to best conduct analyses and evaluate existing hypotheses. The utility of examining other cultural domains phylogenetically is discussed.

The authors examine musical diversity in India using cantometric data from 32 Indian societies with the goal of better understanding how music varies between and within cultures. They find very minor musical differences between language families, greater diversity between societies but within language families, and the most variation within societies.

The article discusses the role of toys and tools in the development of skills and cultural transmission in hunter-gatherer societies. The authors present a cross-cultural inventory of objects made for and by hunter-gatherer children and adolescents, finding that toys and tools were primarily handled outside of explicit pedagogical contexts, and there is little evidence for formalised apprenticeships. The authors suggest that children's self-directed interactions with objects, especially during play, have a critical role in early-age enskillment. Both boys and girls tend to use objects in work and play that emulate the gendered division of labor in their communities, and many objects made by and for children had full-scale counterparts. Finally, the authors argue that the peer group is crucial to skill acquisition in hunter-gatherer societies.
