Description:
The social organization of mobile hunter-gatherers has several derived features, including low within-camp relatedness and fluid meta-groups. Although these features have been proposed to have provided the selective context for the evolution of human hypercooperation and cumulative culture, how such a distinctive social system may have emerged remains unclear. We present an agent-based model suggesting that, even if all individuals in a community seek to live with as many kin as possible, within-camp relatedness is reduced if men and women have equal influence in selecting camp members. Our model closely approximates observed patterns of co-residence among Agta and Mbendjele BaYaka hunter-gatherers. Our results suggest that pair-bonding and increased sex egalitarianism in human evolutionary history may have had a transformative effect on human social organization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dyble, M -- Salali, G D -- Chaudhary, N -- Page, A -- Smith, D -- Thompson, J -- Vinicius, L -- Mace, R -- Migliano, A B -- New York, N.Y. -- Science. 2015 May 15;348(6236):796-8. doi: 10.1126/science.aaa5139.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University College London (UCL) Anthropology, 14 Taviton Street, London WC1H 0BW, UK. mark.dyble.12@ucl.ac.uk. ; University College London (UCL) Anthropology, 14 Taviton Street, London WC1H 0BW, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25977551" target="_blank"〉PubMed〈/a〉
