However, little is known about how actors choose out-group cooperative partners. The existing literature suggests that (in-group) partner choice is based on characteristics associated with greater cooperation (e.g., trustworthiness and productivity). Is out-group partner choice based on the same criteria as in-group? Because out-groups may be unique sources of resource access, we suggest that out-group partner choice should track characteristics of both the candidate partner and the partner's group that are associated with benefits for the actor. To assess partner choice, we employed a non-anonymous, one-shot economic game where participants could allocate money towards in-group and out-group strangers. Participants were from three populations of Bolivian horticulturalists (n = 200) that range in their market integration and their mobility, thus capturing variation in potential benefits to out-group cooperation. We find that individual-level qualities of prospective partners, such as wealth and trustworthiness, affect allocation behavior differently for in-group vs out-group prospective partners. While we find no consistent effects of perceived group qualities on a donor's giving to in-group and out-group members, the relevance of out-group market resource access for Tsimane' donors' allocations suggests that, at least when it comes to dividing a limited resource, qualities associated with a group can affect partner preference. Taken together, results provide insight into patterns of intergroup relationship building that have been crucial in the human lineage.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="dbbbc116b620cb033fe9434b84b2367e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":54881448,"asset_id":35017669,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/54881448/download_file?st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="35017669"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="35017669"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 35017669; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=35017669]").text(description); $(".js-view-count[data-work-id=35017669]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 35017669; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='35017669']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 35017669, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "dbbbc116b620cb033fe9434b84b2367e" } } $('.js-work-strip[data-work-id=35017669]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":35017669,"title":"When to diversify, and with whom?

Osteoporosis should be readily observable in pre-industrial societies if it was regularly experienced over human history. In this study of 142 older adult Tsimane forager-horticulturalists (mean age ± SD = 62.1 ± 8.6, range = 50-85, 51% female) we use calcaneal quantitative ultrasonography (qUS) to assess bone status, document prevalence of adults with reduced bone status, and identify factors (demographic, anthropometric, immunological, kinesthetic) associated with reduced bone status. Men (23%) are as likely as women (25%) to have reduced bone status, although age-related decline in qUS parameters is attenuated for men. Adiposity and fat-free mass positively co-vary with qUS parameters for women but not men. Leukocyte count is inversely associated with qUS parameters controlling for potential confounders; leukocyte count is positively correlated within adults over time, and adults with persistently low counts have higher adjusted qUS parameters (6-8%) than adults with a high count.

Agriculture originated only 10,000 years ago and has been practiced by the majority of the world's population for just two or three millennia, a relatively brief period of time for selection to act. Anatomically modern humans evolved some 150,000-200,000 years ago. This means that natural selection on age profiles of physical function, morbidity and mortality hazards occurred largely in the context of a foraging lifestyle. Yet, very little is known about the aging process among hunting and gathering peoples.","grobid_abstract_attachment_id":42696049},"translated_abstract":null,"internal_url":"https://www.academia.edu/21988410/The_Human_Life_Course_and_the_Biodemography_of_Aging","translated_internal_url":"","created_at":"2016-02-15T02:31:25.217-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":37905717,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":42696049,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696049/thumbnails/1.jpg","file_name":"NIA2004pdf.pdf","download_url":"https://www.academia.edu/attachments/42696049/download_file?st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"The_Human_Life_Course_and_the_Biodemogra.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696049/NIA2004pdf-libre.pdf?1455640742=\u0026response-content-disposition=attachment%3B+filename%3DThe_Human_Life_Course_and_the_Biodemogra.pdf\u0026Expires=1732497936\u0026Signature=JcW6xcELDuZ7HjFaF1nb7pPONH~pOjxtwr9SqKnDWgakEmB3MIH6r~b9ywmxhW3MVKTBJHOyfUyO00yQJkxuBMfl28ZohIHiZbvA5ExBbJtG6c06t3mewaYj0LJl28xvtiGlZJdQ1t~55tV1X2hGQsetkWeeTEnlvyQ1E4q8u4FUrp~XgQSvtrQ0SM-bc9a76lRM2yZ33R1DCJx7jH8nEse88F1Xvmkt6Bc6V6xWGbmZAIj6i1B0Lu0yCRl7DrNDlHA~M-ThKjAthE8hmUDkI1XmMczlUUJX52A1JxvO~iZ3wSB1YlAjkk4EHpoDVl0zGiDYzB5iwqsZcjIuFAtxDA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"The_Human_Life_Course_and_the_Biodemography_of_Aging","translated_slug":"","page_count":30,"language":"en","content_type":"Work","owner":{"id":37905717,"first_name":"Michael","middle_initials":null,"last_name":"Gurven","page_name":"MichaelGurven","domain_name":"ucsb","created_at":"2015-11-08T16:37:12.537-08:00","display_name":"Michael Gurven","url":"https://ucsb.academia.edu/MichaelGurven"},"attachments":[{"id":42696049,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696049/thumbnails/1.jpg","file_name":"NIA2004pdf.pdf","download_url":"https://www.academia.edu/attachments/42696049/download_file?st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"The_Human_Life_Course_and_the_Biodemogra.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696049/NIA2004pdf-libre.pdf?1455640742=\u0026response-content-disposition=attachment%3B+filename%3DThe_Human_Life_Course_and_the_Biodemogra.pdf\u0026Expires=1732497936\u0026Signature=JcW6xcELDuZ7HjFaF1nb7pPONH~pOjxtwr9SqKnDWgakEmB3MIH6r~b9ywmxhW3MVKTBJHOyfUyO00yQJkxuBMfl28ZohIHiZbvA5ExBbJtG6c06t3mewaYj0LJl28xvtiGlZJdQ1t~55tV1X2hGQsetkWeeTEnlvyQ1E4q8u4FUrp~XgQSvtrQ0SM-bc9a76lRM2yZ33R1DCJx7jH8nEse88F1Xvmkt6Bc6V6xWGbmZAIj6i1B0Lu0yCRl7DrNDlHA~M-ThKjAthE8hmUDkI1XmMczlUUJX52A1JxvO~iZ3wSB1YlAjkk4EHpoDVl0zGiDYzB5iwqsZcjIuFAtxDA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":13859,"name":"Life course","url":"https://www.academia.edu/Documents/in/Life_course"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="21988409"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/21988409/Natural_Sleep_and_Its_Seasonal_Variations_in_Three_Pre_industrial_Societies"><img alt="Research paper thumbnail of Natural Sleep and Its Seasonal Variations in Three Pre-industrial Societies" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/21988409/Natural_Sleep_and_Its_Seasonal_Variations_in_Three_Pre_industrial_Societies">Natural Sleep and Its Seasonal Variations in Three Pre-industrial Societies</a></div><div class="wp-workCard_item"><span>Current biology : CB</span><span>, Jan 2, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">How did humans sleep before the modern era?

The proposal that men hunt wild game as a form of status signaling or \"showing off\" to provide reproductive benefits to the hunter challenges the traditional view that men hunt to provision their families. Two broad assumptions underlie the signaling view: 1) hunting is an inefficient means of obtaining reliable calories; 2) hunted game is a public good and shared widely to others when there is an audience, and without expectation of future reciprocation. If hunters lack the ability to direct food shares, then the ubiquitous observations of male hunting and universal pair bonding cannot be explained from a perspective that emphasizes provisioning and a division of labor. Here we show, however, that there is little direct empirical support for the assumptions of the signaling hypothesis. The ethnographic record depicts a more complex relationship between food sharing patterns, subsistence strategies and the sexual division of labor than has been suggested by recent treatments. We then describe a framework that incorporates trade-offs between mating and subsistence strategies in an economic bargaining context that can help improve our understanding of men's and women's roles in hunter-gatherer societies. 4 \"show-off\" hypothesis of Hawkes , Hawkes 1993 initially proposed that men hunt because of the social attention and mating benefits that come from providing game resources that are widely shared. This hypothesis was reformulated using costly signaling theory Zahavi 1997, Bliege Bird, Smith, and, and hereafter referred to as the signaling model, to suggest that men's subsistence behavior is designed to provide an honest signal of underlying genotypic or phenotypic quality by targeting large game that are difficult to acquire. This signaling is particularly effective because the transfer of shares of large prey is believed to be outside the control of the hunter and all consumers pay careful attention to men's hunting results in order to obtain shares for themselves (see Bird 1999, Hawkes and. Because hunting is viewed as a form of mating effort or status competition, rather than familial provisioning, pair bonds and marriage have been reinterpreted as publicly recognized property rights designed to reduce mating competition among men, rather than as cooperative unions designed to reap gains from the joint production of offspring O'Connell 1999, Hawkes 2004). The proponents of the signaling model suggest that if men were primarily concerned with familial provisioning their subsistence patterns would mirror those of women, and also that the sexual division of labor will be most pronounced wherever mating yields highest payoffs for men (Bird 1999:72). As Bird (1999:72) states in a recent review, \"the sexual division of labor seems to make more sense as an outcome of conflicts rather than similarities in reproductive goals\". Primatologists have considered similar proposals emphasizing male coercion and mate-guarding, rather than provisioning, in considerations of the evolution of pair bonds and monogamous mating systems (","grobid_abstract_attachment_id":42696047},"translated_abstract":null,"internal_url":"https://www.academia.edu/21988407/Hunting_as_subsistence_and_mating_effort_A_re_evaluation_of_Man_the_Hunter_the_sexual_division_of_labor_and_the_evolution_of_the_nuclear_family","translated_internal_url":"","created_at":"2016-02-15T02:31:24.712-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":37905717,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":42696047,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696047/thumbnails/1.jpg","file_name":"gurven-hill-dlabor.pdf","download_url":"https://www.academia.edu/attachments/42696047/download_file?st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Hunting_as_subsistence_and_mating_effort.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696047/gurven-hill-dlabor-libre.pdf?1455640742=\u0026response-content-disposition=attachment%3B+filename%3DHunting_as_subsistence_and_mating_effort.pdf\u0026Expires=1732497936\u0026Signature=Ga8tJDIxzmQyZ0TQuPoExOG4RfISiji5dqYrHROzn0~ii5CmgTcRYQAEtF0eH9qrB2pqErGy1O7eEcPpWEK0Mlpwo-PweFpeIt6PBXe0dQX4a2UYT~nezLs9mSd5DxCiXsKMycVacs-4jDLjNLCNX0p7HMNGoAGGO6sSgwFlVSvLoCZ3sY4-j-M83Vt8oQT6o5l~1SEXbnaLWUSEiyPGzbQIsZo5ab8fZTRBHP-ifB5xmD4sFZLGEqnDCk~IvA1TXsyMpS3rzqUMcHsT2bOL-VeUj~~Ck-2sePEb8j9XKKRXh4iaBEkBIpTzj6iKpr58UYuAYjqjDRfNqPQy0tz1Gw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Hunting_as_subsistence_and_mating_effort_A_re_evaluation_of_Man_the_Hunter_the_sexual_division_of_labor_and_the_evolution_of_the_nuclear_family","translated_slug":"","page_count":54,"language":"en","content_type":"Work","owner":{"id":37905717,"first_name":"Michael","middle_initials":null,"last_name":"Gurven","page_name":"MichaelGurven","domain_name":"ucsb","created_at":"2015-11-08T16:37:12.537-08:00","display_name":"Michael Gurven","url":"https://ucsb.academia.edu/MichaelGurven"},"attachments":[{"id":42696047,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696047/thumbnails/1.jpg","file_name":"gurven-hill-dlabor.pdf","download_url":"https://www.academia.edu/attachments/42696047/download_file?st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Hunting_as_subsistence_and_mating_effort.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696047/gurven-hill-dlabor-libre.pdf?1455640742=\u0026response-content-disposition=attachment%3B+filename%3DHunting_as_subsistence_and_mating_effort.pdf\u0026Expires=1732497936\u0026Signature=Ga8tJDIxzmQyZ0TQuPoExOG4RfISiji5dqYrHROzn0~ii5CmgTcRYQAEtF0eH9qrB2pqErGy1O7eEcPpWEK0Mlpwo-PweFpeIt6PBXe0dQX4a2UYT~nezLs9mSd5DxCiXsKMycVacs-4jDLjNLCNX0p7HMNGoAGGO6sSgwFlVSvLoCZ3sY4-j-M83Vt8oQT6o5l~1SEXbnaLWUSEiyPGzbQIsZo5ab8fZTRBHP-ifB5xmD4sFZLGEqnDCk~IvA1TXsyMpS3rzqUMcHsT2bOL-VeUj~~Ck-2sePEb8j9XKKRXh4iaBEkBIpTzj6iKpr58UYuAYjqjDRfNqPQy0tz1Gw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":9067,"name":"Division of labor","url":"https://www.academia.edu/Documents/in/Division_of_labor"},{"id":967087,"name":"Mating Effort","url":"https://www.academia.edu/Documents/in/Mating_Effort"}],"urls":[]}, dispatcherData: dispatcherData });

The proposal that men hunt wild game as a form of status signaling or \"showing off\" to provide reproductive benefits to the hunter challenges the traditional view that men hunt to provision their families. Two broad assumptions underlie the signaling view: (1) hunting is a poor means of obtaining food, and (2) hunted game is a public good shared widely with others and without expectation of future reciprocation. If hunters lack the ability to direct food shares and obtain subsequent benefits contingent on redistribution, then the ubiquitous observations of male hunting and universal pair-bonding cannot be explained from a perspective that emphasizes kin provisioning and a division of labor. Here we show that there is little empirical support for the view that men hunt for signaling benefits alone. The ethnographic record depicts a more complex relationship between food sharing patterns, subsistence strategies, mating, and the sexual division of labor. We present a framework incorporating trade-offs between mating and subsistence strategies in an economic bargaining context that contributes to understanding men's and women's roles in huntergatherer societies.","publication_name":"Current Anthropology","grobid_abstract_attachment_id":42696051},"translated_abstract":null,"internal_url":"https://www.academia.edu/21988403/Why_do_men_hunt_A_reevaluation_of_the_man_the_hunter_sexual_division_of_labor_Curr_Anthropol","translated_internal_url":"","created_at":"2016-02-15T02:31:24.015-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":37905717,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":42696051,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696051/thumbnails/1.jpg","file_name":"Why_do_men_hunt_A_reevaluation_of_the_ma20160215-26964-1quwvu1.pdf","download_url":"https://www.academia.edu/attachments/42696051/download_file?st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Why_do_men_hunt_A_reevaluation_of_the_ma.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696051/Why_do_men_hunt_A_reevaluation_of_the_ma20160215-26964-1quwvu1-libre.pdf?1455640740=\u0026response-content-disposition=attachment%3B+filename%3DWhy_do_men_hunt_A_reevaluation_of_the_ma.pdf\u0026Expires=1732497936\u0026Signature=LX0OQh9jXfOJ0iZIcI44OJzOmk16UdVBePgaNIfuPriynGjGCdmvIKZ~2xtRUNm8pSeDK7V8MopduZ-7cubX-gPCpM~fLhw6s-GANClA~evvm2Te1FW6Bn7Ne8SzDbj1lZlvgDNoZnnQhBJTKJR-hR64OFZBhNZrIc-bs41iE1OSuz8MJdq-rcU-3br0N68~~gXKeevL7tbWoo2QlY8ekGKhAdHqftfi2leiZg79soA9MnfcP-g780eDNmWM-FB9BJXohWwqATcdtyEef0OVqiKu7nKowYEWnY6YtchcjsDnOCyZYTRQ9NCLx0XIwcy6jf~hBL9HAcz9bu-TSwIe7g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Why_do_men_hunt_A_reevaluation_of_the_man_the_hunter_sexual_division_of_labor_Curr_Anthropol","translated_slug":"","page_count":24,"language":"en","content_type":"Work","owner":{"id":37905717,"first_name":"Michael","middle_initials":null,"last_name":"Gurven","page_name":"MichaelGurven","domain_name":"ucsb","created_at":"2015-11-08T16:37:12.537-08:00","display_name":"Michael Gurven","url":"https://ucsb.academia.edu/MichaelGurven"},"attachments":[{"id":42696051,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696051/thumbnails/1.jpg","file_name":"Why_do_men_hunt_A_reevaluation_of_the_ma20160215-26964-1quwvu1.pdf","download_url":"https://www.academia.edu/attachments/42696051/download_file?st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Why_do_men_hunt_A_reevaluation_of_the_ma.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696051/Why_do_men_hunt_A_reevaluation_of_the_ma20160215-26964-1quwvu1-libre.pdf?1455640740=\u0026response-content-disposition=attachment%3B+filename%3DWhy_do_men_hunt_A_reevaluation_of_the_ma.pdf\u0026Expires=1732497936\u0026Signature=LX0OQh9jXfOJ0iZIcI44OJzOmk16UdVBePgaNIfuPriynGjGCdmvIKZ~2xtRUNm8pSeDK7V8MopduZ-7cubX-gPCpM~fLhw6s-GANClA~evvm2Te1FW6Bn7Ne8SzDbj1lZlvgDNoZnnQhBJTKJR-hR64OFZBhNZrIc-bs41iE1OSuz8MJdq-rcU-3br0N68~~gXKeevL7tbWoo2QlY8ekGKhAdHqftfi2leiZg79soA9MnfcP-g780eDNmWM-FB9BJXohWwqATcdtyEef0OVqiKu7nKowYEWnY6YtchcjsDnOCyZYTRQ9NCLx0XIwcy6jf~hBL9HAcz9bu-TSwIe7g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":392,"name":"Archaeology","url":"https://www.academia.edu/Documents/in/Archaeology"},{"id":534,"name":"Law","url":"https://www.academia.edu/Documents/in/Law"},{"id":767,"name":"Anthropology","url":"https://www.academia.edu/Documents/in/Anthropology"},{"id":1928546,"name":"Current anthropology","url":"https://www.academia.edu/Documents/in/Current_anthropology"}],"urls":[{"id":6745802,"url":"https://www.researchgate.net/profile/Michael_Gurven/publication/26649224_Why_do_men_hunt_A_reevaluation_of_the_man_the_hunter_sexual_division_of_labor._Curr_Anthropol/links/00b4952533f5292a87000000.pdf"}]}, dispatcherData: dispatcherData });

If so, then moral condemnation should be more severe when transgressions are recent and local, and should be sensitive to the pronouncements of authority figures (who are often arbiters of moral norms), as the fitness pay-offs of moral disapproval will primarily derive from the ramifications of condemning actions that occur within the immediate social arena. Correspondingly, moral transgressions should be viewed as less objectionable if they occur in other places or times, or if local authorities deem them acceptable. These predictions contrast markedly with those derived from prevailing non-evolutionary perspectives on moral judgement. Both classes of theories predict purportedly species-typical patterns, yet to our knowledge, no study to date has investigated moral judgement across a diverse set of societies, including a range of small-scale communities that differ substantially from large highly urbanized nations. We tested these predictions in five small-scale societies and two large-scale societies, finding substantial evidence of moral parochialism and contextual contingency in adults' moral judgements. Results reveal an overarching pattern in which moral condemnation reflects a concern with immediate local considerations, a pattern consistent with a variety of evolutionary accounts of moral judgement.","grobid_abstract_attachment_id":38570177},"translated_abstract":null,"internal_url":"https://www.academia.edu/15178279/Moral_parochialism_and_contextual_contingency_across_seven_societies","translated_internal_url":"","created_at":"2015-08-25T14:26:22.500-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":32464587,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[{"id":5056545,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":null,"co_author_invite_id":517676,"email":"d***r@anthro.ucla.edu","display_order":0,"name":"Daniel Fessler","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056547,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":32500475,"co_author_invite_id":null,"email":"b***t@cod.edu","affiliation":"College of DuPage","display_order":4194304,"name":"Alexander Bolyanatz","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056549,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":419141,"co_author_invite_id":null,"email":"a***r@wsu.edu","affiliation":"The Pennsylvania State University","display_order":7340032,"name":"Anne C Pisor","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056550,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":2116889,"co_author_invite_id":null,"email":"v***r@gmail.com","affiliation":"University of Richmond","display_order":7864320,"name":"Chris von Rueden","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056551,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":3598205,"co_author_invite_id":null,"email":"m***s@gmail.com","affiliation":"Simon Fraser University","display_order":8126464,"name":"Matthew Gervais","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056552,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":15466939,"co_author_invite_id":null,"email":"s***e@gmail.com","affiliation":"Rutgers University","display_order":8257536,"name":"Stephen Stich","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056553,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":28292906,"co_author_invite_id":null,"email":"m***y@gmail.com","affiliation":"Comenius University","display_order":8323072,"name":"Martin Kanovsky","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056554,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":null,"co_author_invite_id":450557,"email":"k***k@u.washington.edu","display_order":8355840,"name":"Geoff Kushnick","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056555,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":null,"co_author_invite_id":450444,"email":"g***k@anu.edu.au","display_order":8372224,"name":"Geoff Kushnick","title":"Moral parochialism and contextual contingency across seven societies"},{"id":13692459,"work_id":15178279,"tagging_user_id":15466939,"tagged_user_id":null,"co_author_invite_id":1757201,"email":"h***h@umich.edu","display_order":8380416,"name":"J.

Human livelihoods require sharing at all life stages: to support infancy, childhood, and adolescence, and to help reduce risk of daily food shortfalls in adulthood. Attempts to understand the evolved human life history require an examination of the conditions that led to the evolution of food sharing. We summarize key findings and recent directions, and raise unexplored questions. Past emphases included testing predictions from several evolutionary models, and the role that sharing may have played in shaping human family formation. The functions of sharing fall into two categories: reducing food shortages that come with relying on a difficult foraging niche, and advertising attractive qualities of the donor. New directions include multivariate analyses of larger samples from a variety of diverse small-scale subsistence populations, greater consideration of the interdependency between producing food and sharing it, incorporation of bargaining theory into exchange models, and greater attention to proximate psychological mechanisms.

We investigate adaptively patterned personality variation among Tsimane' foragerhorticulturalists. Based on a consideration of cost-benefit tradeoffs that likely maintain variation in human prosociality, we hypothesize that individual differences in prosocial personality traits are facultatively calibrated to variation in \"embodied capital\"-that is, knowledge, skills, or somatic traits that increase expected future fitness. In support of this hypothesis, 2 components of embodied capital-physical strength and formal education-associated positively with Tsimane' prosocial leadership orientation (PLO), a broad personality dimension representing gregarious cooperation, interpersonal warmth, and pursuit of leadership. Moreover, using pedigrees to compute heritability estimates, strength and education had additive effects on the heritable variance in PLO, which suggests that prosocial traits may be \"reactively heritable\" by virtue of their calibration to condition-dependent components of embodied capital. Although alternative explanations must be falsified in future research, our findings 1) provide one of the first demonstrations of adaptively patterned personality variation in a small-scale society and 2) illustrate the potential power of an adaptationist approach to elucidate the causal underpinnings of heritable personality variation.","grobid_abstract_attachment_id":37673076},"translated_abstract":null,"internal_url":"https://www.academia.edu/12452681/Adaptive_personality_calibration_in_a_human_society_effects_of_embodied_capital_on_prosocial_traits","translated_internal_url":"","created_at":"2015-05-18T16:07:11.501-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":2116889,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[{"id":4476488,"work_id":12452681,"tagging_user_id":2116889,"tagged_user_id":37905717,"co_author_invite_id":128060,"email":"g***n@anth.ucsb.edu","affiliation":"University of California, Santa Barbara","display_order":0,"name":"Michael Gurven","title":"Adaptive personality calibration in a human society: effects of embodied capital on prosocial traits"},{"id":569826,"work_id":12452681,"tagging_user_id":2116889,"tagged_user_id":25083199,"co_author_invite_id":null,"email":"a***9@gmail.com","affiliation":"California State University, Fullerton","display_order":null,"name":"Aaron Lukaszewski","title":"Adaptive personality calibration in a human society: effects of embodied capital on prosocial traits"}],"downloadable_attachments":[{"id":37673076,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/37673076/thumbnails/1.jpg","file_name":"AdaptivePersonalityCalibration.pdf","download_url":"https://www.academia.edu/attachments/37673076/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Adaptive_personality_calibration_in_a_hu.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/37673076/AdaptivePersonalityCalibration-libre.pdf?1431990883=\u0026response-content-disposition=attachment%3B+filename%3DAdaptive_personality_calibration_in_a_hu.pdf\u0026Expires=1732497937\u0026Signature=TTzlmeXVYsNQANcHyVklFrWBEJto7hqhycKaviSucFZH~EHMYXw2rttoW5dVPv3nLy2WNQM2LVY4z~U6u6pm6j8LajUpuhC6vqL6jzUDGDaAx~wx7QD0h9LK5OGRiWMXYHdjyzYTS~ytcw0wh0LMBP8NH1i~OtLsXfS4crSTF-Uf-Wjzl01tK78MFhXx4gYGdp-XNt45BFXMEloAD8EsNPphc6lz-PJpSaFGIhCCoLs0ZiR7DJNNAS6FSK0rVmAtuOslgs7ILsJJAldWTf-3SYYaY58jjqjCjQXAAAwRVgpzvqNrcFAOstJwlzheWvDwj6iKSw0I2hsmKiHvMoRQFw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Adaptive_personality_calibration_in_a_human_society_effects_of_embodied_capital_on_prosocial_traits","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":2116889,"first_name":"Chris","middle_initials":null,"last_name":"von Rueden","page_name":"ChrisvonRueden","domain_name":"richmond","created_at":"2012-07-13T09:51:32.716-07:00","display_name":"Chris von Rueden","url":"https://richmond.academia.edu/ChrisvonRueden"},"attachments":[{"id":37673076,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/37673076/thumbnails/1.jpg","file_name":"AdaptivePersonalityCalibration.pdf","download_url":"https://www.academia.edu/attachments/37673076/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Adaptive_personality_calibration_in_a_hu.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/37673076/AdaptivePersonalityCalibration-libre.pdf?1431990883=\u0026response-content-disposition=attachment%3B+filename%3DAdaptive_personality_calibration_in_a_hu.pdf\u0026Expires=1732497937\u0026Signature=TTzlmeXVYsNQANcHyVklFrWBEJto7hqhycKaviSucFZH~EHMYXw2rttoW5dVPv3nLy2WNQM2LVY4z~U6u6pm6j8LajUpuhC6vqL6jzUDGDaAx~wx7QD0h9LK5OGRiWMXYHdjyzYTS~ytcw0wh0LMBP8NH1i~OtLsXfS4crSTF-Uf-Wjzl01tK78MFhXx4gYGdp-XNt45BFXMEloAD8EsNPphc6lz-PJpSaFGIhCCoLs0ZiR7DJNNAS6FSK0rVmAtuOslgs7ILsJJAldWTf-3SYYaY58jjqjCjQXAAAwRVgpzvqNrcFAOstJwlzheWvDwj6iKSw0I2hsmKiHvMoRQFw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":242,"name":"Personality Psychology","url":"https://www.academia.edu/Documents/in/Personality_Psychology"},{"id":4654,"name":"Evolution of Personality","url":"https://www.academia.edu/Documents/in/Evolution_of_Personality"}],"urls":[]}, dispatcherData: dispatcherData });

However, little is known about how actors choose out-group cooperative partners. The existing literature suggests that (in-group) partner choice is based on characteristics associated with greater cooperation (e.g., trustworthiness and productivity). Is out-group partner choice based on the same criteria as in-group? Because out-groups may be unique sources of resource access, we suggest that out-group partner choice should track characteristics of both the candidate partner and the partner's group that are associated with benefits for the actor. To assess partner choice, we employed a non-anonymous, one-shot economic game where participants could allocate money towards in-group and out-group strangers. Participants were from three populations of Bolivian horticulturalists (n = 200) that range in their market integration and their mobility, thus capturing variation in potential benefits to out-group cooperation. We find that individual-level qualities of prospective partners, such as wealth and trustworthiness, affect allocation behavior differently for in-group vs out-group prospective partners. While we find no consistent effects of perceived group qualities on a donor's giving to in-group and out-group members, the relevance of out-group market resource access for Tsimane' donors' allocations suggests that, at least when it comes to dividing a limited resource, qualities associated with a group can affect partner preference. Taken together, results provide insight into patterns of intergroup relationship building that have been crucial in the human lineage.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="dbbbc116b620cb033fe9434b84b2367e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":54881448,"asset_id":35017669,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/54881448/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="35017669"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="35017669"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 35017669; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=35017669]").text(description); $(".js-view-count[data-work-id=35017669]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 35017669; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='35017669']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 35017669, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "dbbbc116b620cb033fe9434b84b2367e" } } $('.js-work-strip[data-work-id=35017669]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":35017669,"title":"When to diversify, and with whom?

Osteoporosis should be readily observable in pre-industrial societies if it was regularly experienced over human history. In this study of 142 older adult Tsimane forager-horticulturalists (mean age ± SD = 62.1 ± 8.6, range = 50-85, 51% female) we use calcaneal quantitative ultrasonography (qUS) to assess bone status, document prevalence of adults with reduced bone status, and identify factors (demographic, anthropometric, immunological, kinesthetic) associated with reduced bone status. Men (23%) are as likely as women (25%) to have reduced bone status, although age-related decline in qUS parameters is attenuated for men. Adiposity and fat-free mass positively co-vary with qUS parameters for women but not men. Leukocyte count is inversely associated with qUS parameters controlling for potential confounders; leukocyte count is positively correlated within adults over time, and adults with persistently low counts have higher adjusted qUS parameters (6-8%) than adults with a high count.

Agriculture originated only 10,000 years ago and has been practiced by the majority of the world's population for just two or three millennia, a relatively brief period of time for selection to act. Anatomically modern humans evolved some 150,000-200,000 years ago. This means that natural selection on age profiles of physical function, morbidity and mortality hazards occurred largely in the context of a foraging lifestyle. Yet, very little is known about the aging process among hunting and gathering peoples.","grobid_abstract_attachment_id":42696049},"translated_abstract":null,"internal_url":"https://www.academia.edu/21988410/The_Human_Life_Course_and_the_Biodemography_of_Aging","translated_internal_url":"","created_at":"2016-02-15T02:31:25.217-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":37905717,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":42696049,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696049/thumbnails/1.jpg","file_name":"NIA2004pdf.pdf","download_url":"https://www.academia.edu/attachments/42696049/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"The_Human_Life_Course_and_the_Biodemogra.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696049/NIA2004pdf-libre.pdf?1455640742=\u0026response-content-disposition=attachment%3B+filename%3DThe_Human_Life_Course_and_the_Biodemogra.pdf\u0026Expires=1732497936\u0026Signature=JcW6xcELDuZ7HjFaF1nb7pPONH~pOjxtwr9SqKnDWgakEmB3MIH6r~b9ywmxhW3MVKTBJHOyfUyO00yQJkxuBMfl28ZohIHiZbvA5ExBbJtG6c06t3mewaYj0LJl28xvtiGlZJdQ1t~55tV1X2hGQsetkWeeTEnlvyQ1E4q8u4FUrp~XgQSvtrQ0SM-bc9a76lRM2yZ33R1DCJx7jH8nEse88F1Xvmkt6Bc6V6xWGbmZAIj6i1B0Lu0yCRl7DrNDlHA~M-ThKjAthE8hmUDkI1XmMczlUUJX52A1JxvO~iZ3wSB1YlAjkk4EHpoDVl0zGiDYzB5iwqsZcjIuFAtxDA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"The_Human_Life_Course_and_the_Biodemography_of_Aging","translated_slug":"","page_count":30,"language":"en","content_type":"Work","owner":{"id":37905717,"first_name":"Michael","middle_initials":null,"last_name":"Gurven","page_name":"MichaelGurven","domain_name":"ucsb","created_at":"2015-11-08T16:37:12.537-08:00","display_name":"Michael Gurven","url":"https://ucsb.academia.edu/MichaelGurven"},"attachments":[{"id":42696049,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696049/thumbnails/1.jpg","file_name":"NIA2004pdf.pdf","download_url":"https://www.academia.edu/attachments/42696049/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"The_Human_Life_Course_and_the_Biodemogra.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696049/NIA2004pdf-libre.pdf?1455640742=\u0026response-content-disposition=attachment%3B+filename%3DThe_Human_Life_Course_and_the_Biodemogra.pdf\u0026Expires=1732497936\u0026Signature=JcW6xcELDuZ7HjFaF1nb7pPONH~pOjxtwr9SqKnDWgakEmB3MIH6r~b9ywmxhW3MVKTBJHOyfUyO00yQJkxuBMfl28ZohIHiZbvA5ExBbJtG6c06t3mewaYj0LJl28xvtiGlZJdQ1t~55tV1X2hGQsetkWeeTEnlvyQ1E4q8u4FUrp~XgQSvtrQ0SM-bc9a76lRM2yZ33R1DCJx7jH8nEse88F1Xvmkt6Bc6V6xWGbmZAIj6i1B0Lu0yCRl7DrNDlHA~M-ThKjAthE8hmUDkI1XmMczlUUJX52A1JxvO~iZ3wSB1YlAjkk4EHpoDVl0zGiDYzB5iwqsZcjIuFAtxDA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":13859,"name":"Life course","url":"https://www.academia.edu/Documents/in/Life_course"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="21988409"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/21988409/Natural_Sleep_and_Its_Seasonal_Variations_in_Three_Pre_industrial_Societies"><img alt="Research paper thumbnail of Natural Sleep and Its Seasonal Variations in Three Pre-industrial Societies" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/21988409/Natural_Sleep_and_Its_Seasonal_Variations_in_Three_Pre_industrial_Societies">Natural Sleep and Its Seasonal Variations in Three Pre-industrial Societies</a></div><div class="wp-workCard_item"><span>Current biology : CB</span><span>, Jan 2, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">How did humans sleep before the modern era?

The proposal that men hunt wild game as a form of status signaling or \"showing off\" to provide reproductive benefits to the hunter challenges the traditional view that men hunt to provision their families. Two broad assumptions underlie the signaling view: 1) hunting is an inefficient means of obtaining reliable calories; 2) hunted game is a public good and shared widely to others when there is an audience, and without expectation of future reciprocation. If hunters lack the ability to direct food shares, then the ubiquitous observations of male hunting and universal pair bonding cannot be explained from a perspective that emphasizes provisioning and a division of labor. Here we show, however, that there is little direct empirical support for the assumptions of the signaling hypothesis. The ethnographic record depicts a more complex relationship between food sharing patterns, subsistence strategies and the sexual division of labor than has been suggested by recent treatments. We then describe a framework that incorporates trade-offs between mating and subsistence strategies in an economic bargaining context that can help improve our understanding of men's and women's roles in hunter-gatherer societies. 4 \"show-off\" hypothesis of Hawkes , Hawkes 1993 initially proposed that men hunt because of the social attention and mating benefits that come from providing game resources that are widely shared. This hypothesis was reformulated using costly signaling theory Zahavi 1997, Bliege Bird, Smith, and, and hereafter referred to as the signaling model, to suggest that men's subsistence behavior is designed to provide an honest signal of underlying genotypic or phenotypic quality by targeting large game that are difficult to acquire. This signaling is particularly effective because the transfer of shares of large prey is believed to be outside the control of the hunter and all consumers pay careful attention to men's hunting results in order to obtain shares for themselves (see Bird 1999, Hawkes and. Because hunting is viewed as a form of mating effort or status competition, rather than familial provisioning, pair bonds and marriage have been reinterpreted as publicly recognized property rights designed to reduce mating competition among men, rather than as cooperative unions designed to reap gains from the joint production of offspring O'Connell 1999, Hawkes 2004). The proponents of the signaling model suggest that if men were primarily concerned with familial provisioning their subsistence patterns would mirror those of women, and also that the sexual division of labor will be most pronounced wherever mating yields highest payoffs for men (Bird 1999:72). As Bird (1999:72) states in a recent review, \"the sexual division of labor seems to make more sense as an outcome of conflicts rather than similarities in reproductive goals\". Primatologists have considered similar proposals emphasizing male coercion and mate-guarding, rather than provisioning, in considerations of the evolution of pair bonds and monogamous mating systems (","grobid_abstract_attachment_id":42696047},"translated_abstract":null,"internal_url":"https://www.academia.edu/21988407/Hunting_as_subsistence_and_mating_effort_A_re_evaluation_of_Man_the_Hunter_the_sexual_division_of_labor_and_the_evolution_of_the_nuclear_family","translated_internal_url":"","created_at":"2016-02-15T02:31:24.712-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":37905717,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":42696047,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696047/thumbnails/1.jpg","file_name":"gurven-hill-dlabor.pdf","download_url":"https://www.academia.edu/attachments/42696047/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Hunting_as_subsistence_and_mating_effort.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696047/gurven-hill-dlabor-libre.pdf?1455640742=\u0026response-content-disposition=attachment%3B+filename%3DHunting_as_subsistence_and_mating_effort.pdf\u0026Expires=1732497936\u0026Signature=Ga8tJDIxzmQyZ0TQuPoExOG4RfISiji5dqYrHROzn0~ii5CmgTcRYQAEtF0eH9qrB2pqErGy1O7eEcPpWEK0Mlpwo-PweFpeIt6PBXe0dQX4a2UYT~nezLs9mSd5DxCiXsKMycVacs-4jDLjNLCNX0p7HMNGoAGGO6sSgwFlVSvLoCZ3sY4-j-M83Vt8oQT6o5l~1SEXbnaLWUSEiyPGzbQIsZo5ab8fZTRBHP-ifB5xmD4sFZLGEqnDCk~IvA1TXsyMpS3rzqUMcHsT2bOL-VeUj~~Ck-2sePEb8j9XKKRXh4iaBEkBIpTzj6iKpr58UYuAYjqjDRfNqPQy0tz1Gw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Hunting_as_subsistence_and_mating_effort_A_re_evaluation_of_Man_the_Hunter_the_sexual_division_of_labor_and_the_evolution_of_the_nuclear_family","translated_slug":"","page_count":54,"language":"en","content_type":"Work","owner":{"id":37905717,"first_name":"Michael","middle_initials":null,"last_name":"Gurven","page_name":"MichaelGurven","domain_name":"ucsb","created_at":"2015-11-08T16:37:12.537-08:00","display_name":"Michael Gurven","url":"https://ucsb.academia.edu/MichaelGurven"},"attachments":[{"id":42696047,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696047/thumbnails/1.jpg","file_name":"gurven-hill-dlabor.pdf","download_url":"https://www.academia.edu/attachments/42696047/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Hunting_as_subsistence_and_mating_effort.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696047/gurven-hill-dlabor-libre.pdf?1455640742=\u0026response-content-disposition=attachment%3B+filename%3DHunting_as_subsistence_and_mating_effort.pdf\u0026Expires=1732497936\u0026Signature=Ga8tJDIxzmQyZ0TQuPoExOG4RfISiji5dqYrHROzn0~ii5CmgTcRYQAEtF0eH9qrB2pqErGy1O7eEcPpWEK0Mlpwo-PweFpeIt6PBXe0dQX4a2UYT~nezLs9mSd5DxCiXsKMycVacs-4jDLjNLCNX0p7HMNGoAGGO6sSgwFlVSvLoCZ3sY4-j-M83Vt8oQT6o5l~1SEXbnaLWUSEiyPGzbQIsZo5ab8fZTRBHP-ifB5xmD4sFZLGEqnDCk~IvA1TXsyMpS3rzqUMcHsT2bOL-VeUj~~Ck-2sePEb8j9XKKRXh4iaBEkBIpTzj6iKpr58UYuAYjqjDRfNqPQy0tz1Gw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":9067,"name":"Division of labor","url":"https://www.academia.edu/Documents/in/Division_of_labor"},{"id":967087,"name":"Mating Effort","url":"https://www.academia.edu/Documents/in/Mating_Effort"}],"urls":[]}, dispatcherData: dispatcherData });

The proposal that men hunt wild game as a form of status signaling or \"showing off\" to provide reproductive benefits to the hunter challenges the traditional view that men hunt to provision their families. Two broad assumptions underlie the signaling view: (1) hunting is a poor means of obtaining food, and (2) hunted game is a public good shared widely with others and without expectation of future reciprocation. If hunters lack the ability to direct food shares and obtain subsequent benefits contingent on redistribution, then the ubiquitous observations of male hunting and universal pair-bonding cannot be explained from a perspective that emphasizes kin provisioning and a division of labor. Here we show that there is little empirical support for the view that men hunt for signaling benefits alone. The ethnographic record depicts a more complex relationship between food sharing patterns, subsistence strategies, mating, and the sexual division of labor. We present a framework incorporating trade-offs between mating and subsistence strategies in an economic bargaining context that contributes to understanding men's and women's roles in huntergatherer societies.","publication_name":"Current Anthropology","grobid_abstract_attachment_id":42696051},"translated_abstract":null,"internal_url":"https://www.academia.edu/21988403/Why_do_men_hunt_A_reevaluation_of_the_man_the_hunter_sexual_division_of_labor_Curr_Anthropol","translated_internal_url":"","created_at":"2016-02-15T02:31:24.015-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":37905717,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":42696051,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696051/thumbnails/1.jpg","file_name":"Why_do_men_hunt_A_reevaluation_of_the_ma20160215-26964-1quwvu1.pdf","download_url":"https://www.academia.edu/attachments/42696051/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Why_do_men_hunt_A_reevaluation_of_the_ma.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696051/Why_do_men_hunt_A_reevaluation_of_the_ma20160215-26964-1quwvu1-libre.pdf?1455640740=\u0026response-content-disposition=attachment%3B+filename%3DWhy_do_men_hunt_A_reevaluation_of_the_ma.pdf\u0026Expires=1732497936\u0026Signature=LX0OQh9jXfOJ0iZIcI44OJzOmk16UdVBePgaNIfuPriynGjGCdmvIKZ~2xtRUNm8pSeDK7V8MopduZ-7cubX-gPCpM~fLhw6s-GANClA~evvm2Te1FW6Bn7Ne8SzDbj1lZlvgDNoZnnQhBJTKJR-hR64OFZBhNZrIc-bs41iE1OSuz8MJdq-rcU-3br0N68~~gXKeevL7tbWoo2QlY8ekGKhAdHqftfi2leiZg79soA9MnfcP-g780eDNmWM-FB9BJXohWwqATcdtyEef0OVqiKu7nKowYEWnY6YtchcjsDnOCyZYTRQ9NCLx0XIwcy6jf~hBL9HAcz9bu-TSwIe7g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Why_do_men_hunt_A_reevaluation_of_the_man_the_hunter_sexual_division_of_labor_Curr_Anthropol","translated_slug":"","page_count":24,"language":"en","content_type":"Work","owner":{"id":37905717,"first_name":"Michael","middle_initials":null,"last_name":"Gurven","page_name":"MichaelGurven","domain_name":"ucsb","created_at":"2015-11-08T16:37:12.537-08:00","display_name":"Michael Gurven","url":"https://ucsb.academia.edu/MichaelGurven"},"attachments":[{"id":42696051,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/42696051/thumbnails/1.jpg","file_name":"Why_do_men_hunt_A_reevaluation_of_the_ma20160215-26964-1quwvu1.pdf","download_url":"https://www.academia.edu/attachments/42696051/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Why_do_men_hunt_A_reevaluation_of_the_ma.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42696051/Why_do_men_hunt_A_reevaluation_of_the_ma20160215-26964-1quwvu1-libre.pdf?1455640740=\u0026response-content-disposition=attachment%3B+filename%3DWhy_do_men_hunt_A_reevaluation_of_the_ma.pdf\u0026Expires=1732497936\u0026Signature=LX0OQh9jXfOJ0iZIcI44OJzOmk16UdVBePgaNIfuPriynGjGCdmvIKZ~2xtRUNm8pSeDK7V8MopduZ-7cubX-gPCpM~fLhw6s-GANClA~evvm2Te1FW6Bn7Ne8SzDbj1lZlvgDNoZnnQhBJTKJR-hR64OFZBhNZrIc-bs41iE1OSuz8MJdq-rcU-3br0N68~~gXKeevL7tbWoo2QlY8ekGKhAdHqftfi2leiZg79soA9MnfcP-g780eDNmWM-FB9BJXohWwqATcdtyEef0OVqiKu7nKowYEWnY6YtchcjsDnOCyZYTRQ9NCLx0XIwcy6jf~hBL9HAcz9bu-TSwIe7g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":392,"name":"Archaeology","url":"https://www.academia.edu/Documents/in/Archaeology"},{"id":534,"name":"Law","url":"https://www.academia.edu/Documents/in/Law"},{"id":767,"name":"Anthropology","url":"https://www.academia.edu/Documents/in/Anthropology"},{"id":1928546,"name":"Current anthropology","url":"https://www.academia.edu/Documents/in/Current_anthropology"}],"urls":[{"id":6745802,"url":"https://www.researchgate.net/profile/Michael_Gurven/publication/26649224_Why_do_men_hunt_A_reevaluation_of_the_man_the_hunter_sexual_division_of_labor._Curr_Anthropol/links/00b4952533f5292a87000000.pdf"}]}, dispatcherData: dispatcherData });

If so, then moral condemnation should be more severe when transgressions are recent and local, and should be sensitive to the pronouncements of authority figures (who are often arbiters of moral norms), as the fitness pay-offs of moral disapproval will primarily derive from the ramifications of condemning actions that occur within the immediate social arena. Correspondingly, moral transgressions should be viewed as less objectionable if they occur in other places or times, or if local authorities deem them acceptable. These predictions contrast markedly with those derived from prevailing non-evolutionary perspectives on moral judgement. Both classes of theories predict purportedly species-typical patterns, yet to our knowledge, no study to date has investigated moral judgement across a diverse set of societies, including a range of small-scale communities that differ substantially from large highly urbanized nations. We tested these predictions in five small-scale societies and two large-scale societies, finding substantial evidence of moral parochialism and contextual contingency in adults' moral judgements. Results reveal an overarching pattern in which moral condemnation reflects a concern with immediate local considerations, a pattern consistent with a variety of evolutionary accounts of moral judgement.","grobid_abstract_attachment_id":38570177},"translated_abstract":null,"internal_url":"https://www.academia.edu/15178279/Moral_parochialism_and_contextual_contingency_across_seven_societies","translated_internal_url":"","created_at":"2015-08-25T14:26:22.500-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":32464587,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[{"id":5056545,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":null,"co_author_invite_id":517676,"email":"d***r@anthro.ucla.edu","display_order":0,"name":"Daniel Fessler","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056547,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":32500475,"co_author_invite_id":null,"email":"b***t@cod.edu","affiliation":"College of DuPage","display_order":4194304,"name":"Alexander Bolyanatz","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056549,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":419141,"co_author_invite_id":null,"email":"a***r@wsu.edu","affiliation":"The Pennsylvania State University","display_order":7340032,"name":"Anne C Pisor","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056550,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":2116889,"co_author_invite_id":null,"email":"v***r@gmail.com","affiliation":"University of Richmond","display_order":7864320,"name":"Chris von Rueden","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056551,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":3598205,"co_author_invite_id":null,"email":"m***s@gmail.com","affiliation":"Simon Fraser University","display_order":8126464,"name":"Matthew Gervais","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056552,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":15466939,"co_author_invite_id":null,"email":"s***e@gmail.com","affiliation":"Rutgers University","display_order":8257536,"name":"Stephen Stich","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056553,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":28292906,"co_author_invite_id":null,"email":"m***y@gmail.com","affiliation":"Comenius University","display_order":8323072,"name":"Martin Kanovsky","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056554,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":null,"co_author_invite_id":450557,"email":"k***k@u.washington.edu","display_order":8355840,"name":"Geoff Kushnick","title":"Moral parochialism and contextual contingency across seven societies"},{"id":5056555,"work_id":15178279,"tagging_user_id":32464587,"tagged_user_id":null,"co_author_invite_id":450444,"email":"g***k@anu.edu.au","display_order":8372224,"name":"Geoff Kushnick","title":"Moral parochialism and contextual contingency across seven societies"},{"id":13692459,"work_id":15178279,"tagging_user_id":15466939,"tagged_user_id":null,"co_author_invite_id":1757201,"email":"h***h@umich.edu","display_order":8380416,"name":"J.

Human livelihoods require sharing at all life stages: to support infancy, childhood, and adolescence, and to help reduce risk of daily food shortfalls in adulthood. Attempts to understand the evolved human life history require an examination of the conditions that led to the evolution of food sharing. We summarize key findings and recent directions, and raise unexplored questions. Past emphases included testing predictions from several evolutionary models, and the role that sharing may have played in shaping human family formation. The functions of sharing fall into two categories: reducing food shortages that come with relying on a difficult foraging niche, and advertising attractive qualities of the donor. New directions include multivariate analyses of larger samples from a variety of diverse small-scale subsistence populations, greater consideration of the interdependency between producing food and sharing it, incorporation of bargaining theory into exchange models, and greater attention to proximate psychological mechanisms.

We investigate adaptively patterned personality variation among Tsimane' foragerhorticulturalists. Based on a consideration of cost-benefit tradeoffs that likely maintain variation in human prosociality, we hypothesize that individual differences in prosocial personality traits are facultatively calibrated to variation in \"embodied capital\"-that is, knowledge, skills, or somatic traits that increase expected future fitness. In support of this hypothesis, 2 components of embodied capital-physical strength and formal education-associated positively with Tsimane' prosocial leadership orientation (PLO), a broad personality dimension representing gregarious cooperation, interpersonal warmth, and pursuit of leadership. Moreover, using pedigrees to compute heritability estimates, strength and education had additive effects on the heritable variance in PLO, which suggests that prosocial traits may be \"reactively heritable\" by virtue of their calibration to condition-dependent components of embodied capital. Although alternative explanations must be falsified in future research, our findings 1) provide one of the first demonstrations of adaptively patterned personality variation in a small-scale society and 2) illustrate the potential power of an adaptationist approach to elucidate the causal underpinnings of heritable personality variation.","grobid_abstract_attachment_id":37673076},"translated_abstract":null,"internal_url":"https://www.academia.edu/12452681/Adaptive_personality_calibration_in_a_human_society_effects_of_embodied_capital_on_prosocial_traits","translated_internal_url":"","created_at":"2015-05-18T16:07:11.501-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":2116889,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[{"id":4476488,"work_id":12452681,"tagging_user_id":2116889,"tagged_user_id":37905717,"co_author_invite_id":128060,"email":"g***n@anth.ucsb.edu","affiliation":"University of California, Santa Barbara","display_order":0,"name":"Michael Gurven","title":"Adaptive personality calibration in a human society: effects of embodied capital on prosocial traits"},{"id":569826,"work_id":12452681,"tagging_user_id":2116889,"tagged_user_id":25083199,"co_author_invite_id":null,"email":"a***9@gmail.com","affiliation":"California State University, Fullerton","display_order":null,"name":"Aaron Lukaszewski","title":"Adaptive personality calibration in a human society: effects of embodied capital on prosocial traits"}],"downloadable_attachments":[{"id":37673076,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/37673076/thumbnails/1.jpg","file_name":"AdaptivePersonalityCalibration.pdf","download_url":"https://www.academia.edu/attachments/37673076/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Adaptive_personality_calibration_in_a_hu.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/37673076/AdaptivePersonalityCalibration-libre.pdf?1431990883=\u0026response-content-disposition=attachment%3B+filename%3DAdaptive_personality_calibration_in_a_hu.pdf\u0026Expires=1732497937\u0026Signature=TTzlmeXVYsNQANcHyVklFrWBEJto7hqhycKaviSucFZH~EHMYXw2rttoW5dVPv3nLy2WNQM2LVY4z~U6u6pm6j8LajUpuhC6vqL6jzUDGDaAx~wx7QD0h9LK5OGRiWMXYHdjyzYTS~ytcw0wh0LMBP8NH1i~OtLsXfS4crSTF-Uf-Wjzl01tK78MFhXx4gYGdp-XNt45BFXMEloAD8EsNPphc6lz-PJpSaFGIhCCoLs0ZiR7DJNNAS6FSK0rVmAtuOslgs7ILsJJAldWTf-3SYYaY58jjqjCjQXAAAwRVgpzvqNrcFAOstJwlzheWvDwj6iKSw0I2hsmKiHvMoRQFw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Adaptive_personality_calibration_in_a_human_society_effects_of_embodied_capital_on_prosocial_traits","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":2116889,"first_name":"Chris","middle_initials":null,"last_name":"von Rueden","page_name":"ChrisvonRueden","domain_name":"richmond","created_at":"2012-07-13T09:51:32.716-07:00","display_name":"Chris von Rueden","url":"https://richmond.academia.edu/ChrisvonRueden"},"attachments":[{"id":37673076,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/37673076/thumbnails/1.jpg","file_name":"AdaptivePersonalityCalibration.pdf","download_url":"https://www.academia.edu/attachments/37673076/download_file?st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&st=MTczMjQ5NDMzNyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Adaptive_personality_calibration_in_a_hu.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/37673076/AdaptivePersonalityCalibration-libre.pdf?1431990883=\u0026response-content-disposition=attachment%3B+filename%3DAdaptive_personality_calibration_in_a_hu.pdf\u0026Expires=1732497937\u0026Signature=TTzlmeXVYsNQANcHyVklFrWBEJto7hqhycKaviSucFZH~EHMYXw2rttoW5dVPv3nLy2WNQM2LVY4z~U6u6pm6j8LajUpuhC6vqL6jzUDGDaAx~wx7QD0h9LK5OGRiWMXYHdjyzYTS~ytcw0wh0LMBP8NH1i~OtLsXfS4crSTF-Uf-Wjzl01tK78MFhXx4gYGdp-XNt45BFXMEloAD8EsNPphc6lz-PJpSaFGIhCCoLs0ZiR7DJNNAS6FSK0rVmAtuOslgs7ILsJJAldWTf-3SYYaY58jjqjCjQXAAAwRVgpzvqNrcFAOstJwlzheWvDwj6iKSw0I2hsmKiHvMoRQFw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":242,"name":"Personality Psychology","url":"https://www.academia.edu/Documents/in/Personality_Psychology"},{"id":4654,"name":"Evolution of Personality","url":"https://www.academia.edu/Documents/in/Evolution_of_Personality"}],"urls":[]}, dispatcherData: dispatcherData });
