Childhood Teaching and Learning among Savanna Pumé Hunter-Gatherers : Mismatch between Foraging and Postindustrial Societies.

Karen L Kramer

Hum Nat 2021 Jun 5. Epub 2021 Jun 5.

Department of Anthropology, University of Utah, Salt Lake City, UT, USA.

Research in nonindustrial small-scale societies challenges the common perception that human childhood is universally characterized by a long period of intensive adult investment and dedicated instruction. Using return rate and time allocation data for the Savanna Pumé, a group of South American hunter-gatherers, age patterns in how children learn to become productive foragers and from whom they learn are observed across the transition from childhood to adolescence. Results show that Savanna Pumé children care for their siblings, are important economic contributors, learn by doing rather than by instruction, and spend their time principally in the company of other children.
