Hunter-Gatherer Inter-Band Interaction Rates: Implications for Cumulative Culture
Our species exhibits spectacular success due to cumulative culture. While cognitive evolution of social learning mechanisms may be partially responsible for adaptive human culture, features of early human social structure may also play a role by increasing the number potential models from which to learn innovations. We present interview data on interactions between same-sex adult dyads of Ache ...
متن کاملOrganic fitness: physical activity consistent with our hunter-gatherer heritage.
Many of the pervasive health concerns in modern society are the result of diet and lifestyle choices that are at odds with the evolutionary milieu for which we remain genetically adapted. This systematic displacement from a very physically active lifestyle in a natural outdoor environment to a sedentary indoor lifestyle may be at the root of many chronic diseases that are endemic in our culture...
متن کاملAdaptive memory: fitness relevance and the hunter-gatherer mind.
Recent studies suggest that human memory systems are "tuned" to remember information that is processed in terms of its fitness value. When people are asked to rate the relevance of words to a survival scenario, performance on subsequent surprise memory tests exceeds that obtained after most other known encoding techniques. The present experiments explored this effect using survival scenarios de...
متن کاملSupposing Hunter-gatherer Variability
J B. S. Haldane, the British geneticist, once mused, "my suspicion is that the universe is not only queerer than we suppose ,but queerer than we can suppose" (Haldane 1927:286). This comment can be paraphrased to summarize the fundamental problem presently facing hunter-gatherer studies: there is more variation among recent and especially past hunter-gatherer societies than we have supposed. Th...
