Population-genomic data from 11 Scandinavian Stone Age human remains suggest that hunter-gatherers had lower genetic diversity than that of farmers. Despite their close geographical proximity, the genetic differentiation between the two Stone Age groups was greater than that observed among extant European populations. Additionally, the Scandinavian Neolithic farmers exhibited a greater degree of hunter-gatherer\u2013related admixture than that of the Tyrolean Iceman, who also originated from a farming context. In contrast, Scandinavian hunter-gatherers displayed no significant evidence of introgression from farmers. Our findings suggest that Stone Age foraging groups were historically in low numbers, likely owing to oscillating living conditions or restricted carrying capacity, and that they were partially incorporated into expanding farming groups.<\/p>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-container-core-group-is-layout-db32e940 wp-block-group-is-layout-constrained\" style=\"padding-top:var(--wp--preset--spacing--60);padding-right:var(--wp--preset--spacing--60);padding-bottom:var(--wp--preset--spacing--60);padding-left:var(--wp--preset--spacing--60)\">\n<h2 class=\"wp-block-heading is-style-underlined-heading\">Related content<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/jakobssonlab.iob.uu.se\/wp-content\/uploads\/2024\/05\/Ajvide_frontpage.jpg\" alt=\"\" class=\"wp-image-1369\" style=\"width:728px;height:auto\"\/><figcaption class=\"wp-element-caption\">Photograph: G\u00f6ran Burenhult.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Genomic Diversity and Admixture differs for Stone-Age Scandinavian Foragers and Farmers<\/h2>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.uu.se\/en\/press\/press-releases\/2014\/2014-04-24-genomic-diversity-and-admixture-differs-for-stone-age-scandinavian-foragers-and-farmers\" target=\"_blank\" rel=\"noreferrer noopener\">UU Press Release<\/a><\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>An international team led by researchers at Uppsala University and Stockholm University reports a breakthrough in understanding the demographic history [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":2794,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[17,24,12,18,11],"tags":[70,46,36,41,142,141],"class_list":["post-2793","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-highlights","category-in-the-media","category-news","category-publications","category-research","tag-diversity","tag-genomics","tag-human-past","tag-neolithic","tag-scandinavia","tag-stone-age-2"],"_links":{"self":[{"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/posts\/2793","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/comments?post=2793"}],"version-history":[{"count":1,"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/posts\/2793\/revisions"}],"predecessor-version":[{"id":2795,"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/posts\/2793\/revisions\/2795"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/media\/2794"}],"wp:attachment":[{"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/media?parent=2793"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/categories?post=2793"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/jakobssonlab.iob.uu.se\/index.php\/wp-json\/wp\/v2\/tags?post=2793"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
