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.

What is the relationship between childhood experiences and adult skills? The authors of this article hypothesize that early learning situations can result in psychological effects which can later be reflected in adult skills. To test this hypothesis, they investigate how specific childhood activities which stimulate gestalt brain development, such as creative games and holistic learning experiences, translate into adult gestalt skills, such as complex representations of their environments and originality of art. Through a systems approach which employs three levels of analysis- neurophysiology, psychology, and anthropology- the authors find that children's games and learning techniques are correlated with adult environmental representation and artistic originality, ultimately supporting their hypothesis.
