    The coevolution of parochial altruism and war (2007)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2007-10-27
    Description: Altruism-benefiting fellow group members at a cost to oneself-and parochialism-hostility toward individuals not of one's own ethnic, racial, or other group-are common human behaviors. The intersection of the two-which we term "parochial altruism"-is puzzling from an evolutionary perspective because altruistic or parochial behavior reduces one's payoffs by comparison to what one would gain by eschewing these behaviors. But parochial altruism could have evolved if parochialism promoted intergroup hostilities and the combination of altruism and parochialism contributed to success in these conflicts. Our game-theoretic analysis and agent-based simulations show that under conditions likely to have been experienced by late Pleistocene and early Holocene humans, neither parochialism nor altruism would have been viable singly, but by promoting group conflict, they could have evolved jointly.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choi, Jung-Kyoo -- Bowles, Samuel -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):636-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Economics and Trade, Kyungpook National University, 1370 Sankyuk-dong, Buk-gu, Daegu 702-701, Korea.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17962562" target="_blank"〉PubMed〈/a〉

    Did warfare among ancestral hunter-gatherers affect the evolution of human social behaviors? (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-06-06
    Description: Since Darwin, intergroup hostilities have figured prominently in explanations of the evolution of human social behavior. Yet whether ancestral humans were largely "peaceful" or "warlike" remains controversial. I ask a more precise question: If more cooperative groups were more likely to prevail in conflicts with other groups, was the level of intergroup violence sufficient to influence the evolution of human social behavior? Using a model of the evolutionary impact of between-group competition and a new data set that combines archaeological evidence on causes of death during the Late Pleistocene and early Holocene with ethnographic and historical reports on hunter-gatherer populations, I find that the estimated level of mortality in intergroup conflicts would have had substantial effects, allowing the proliferation of group-beneficial behaviors that were quite costly to the individual altruist.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowles, Samuel -- New York, N.Y. -- Science. 2009 Jun 5;324(5932):1293-8. doi: 10.1126/science.1168112.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA. samuel.bowles@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19498163" target="_blank"〉PubMed〈/a〉

    Warriors, levelers, and the role of conflict in human social evolution (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-19
    Description: The origins of such varied features of contemporary life as the national state and the desire to uphold generous and civic social norms are to be found in a combination of conflict between groups and attenuation of both inequalities and conflicts within groups. In contrast to the adoption of a better tool or a more productive crop, which can be adopted by a single individual, a new institution works only if most people adopt it. This explains why collective action against those benefitting from the status quo at the expense of others, as well as conflict between groups governed by different norms and institutions, figures so prominently in our capacity to adapt to changing circumstances and to harness new knowledge for human benefit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowles, Samuel -- New York, N.Y. -- Science. 2012 May 18;336(6083):876-9. doi: 10.1126/science.1217336.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA. samuel.bowles@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22605768" target="_blank"〉PubMed〈/a〉
