To understand transmission of knowledge and its impact on human evolution history, this study explores the research question: "How do hunter-gatherer children learn subsistence skills?". The authors use meta-ethnography methods on 34 cultures from five continents discussing these topics. The results show that the learning process starts early in infancy when their parents take them to the excursions. In middle childhood, they already acquired gathering skills. Only in the start of adolescence, adults begin teaching how to hunt and to produce complex tools. The learning process continues into adulthood.

This paper examines patterns of cultural learning in pastoralist societies and compares them to those found in hunter-gatherer societies. The study analyzed 198 texts from 13 pastoralist cultures in the eHRAF World Cultures database and found that most cultural skills and knowledge were acquired in early childhood, with parents and non-parental adults as the primary sources of transmission. Teaching was the most common form of learning across all age groups, with minimal variation in transmission between different age groups. While similarities were found between the cultural learning patterns of pastoralists and hunter-gatherers, pastoralists were less likely to mention learning from peers and more likely to mention learning via local enhancement and stimulus enhancement. The importance of teaching did not increase with age in pastoralist societies, unlike in hunter-gatherer societies.

Social scientists are equivocal as to the importance of teaching (as contrasted with other forms of learning) in traditional societies. While many cultural anthropologists have downplayed the importance of teaching, cognitive psychologists often argue that teaching is a salient human universal. Here the authors investigate cultural transmission among 23 hunter-gatherer populations to explore the relative importance of teaching among foragers.

Name-soul belief systems operate under the belief that deceased ancestors will be reincarnated amongst newborn members of the community. This informs the naming process of children amongst these societies. This study samples 11 hunting/gathering/fishing societies with this belief system, comparing and contrasting how the systems are of the same or different origins. Utilizing a neo-functionalist theoretical model the researchers argue that this system reinforces kinship bonds, as new members are viewed as old members returning home, and that the returned ancestors would provide strength and protection to the newborn from more malevolent spirits. The researchers theorize that this practice, in a functionalist anthropology lens, is a way to deal with constant mortality trauma, and to strengthen group cohesion amongst often mobile groups.

This study re-examines the hypotheses offered by Kleiman (1977) linking monogamy in humans to monogamy in other animals. Of seven hypotheses, only two were weakly supported when using a cross-cultural analysis.

This study discusses childcare done by children. While no empirical hypotheses are tested, the authors identify some potential sociocultural and developmental correlates of childcare by children and provide relevant descriptive statistics. Possible correlates include mother-child relationships, conceptions and emergence of childhood stages, organization of play groups, development of social responsibility, sex differences, personality development, cognitive style and cognitive development, motivation and learning.

Textor summarizes cross-cultural findings on societies where subsistence is primarily by 'food gathering' which includes hunting, fishing, and gathering.

Researchers used various hypotheses to determine if cross-country differences in trust and cooperation would predict prosocial COVID-19 responses and policies. Using individual surveys from 34,526 participants from 41 countries, there were no significant associations between trust and cooperation and prosocial behavior, motivation, regulation, or stringency of policies. While the researchers did find significant variation among cross-country individuals, these results were unable to predict country-level prosocial responses.

Textor summarizes cross-cultural findings on polygyny pertaining to cultural, environmental, psychological, and social phenomena.

This study investigates the conceptual frameworks involved in infanticide. Authors first examine data on infanticide and birth ceremonies, particularly the timing of these events and the infant and adult involved in each. Authors also examine reasons for performing infanticide, including illegitimacy, unwanted children, and excess children, finding them similar to reasons for performing abortion. Population control and implications for children's and women's status are also discussed.
