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.
