Their findings, recently published in <\/span><em>Nature<\/em><span>, challenge existing models of early human migration and isolation in North Africa.<\/span><\/p>\n<blockquote>\n<p><strong>&#8220;This discovery reveals a deeply rooted and long-isolated genetic lineage in North Africa,&#8221;<\/strong><span> said Nada Salem of the Max Planck Institute for Evolutionary Anthropology, the study\u2019s lead author. <\/span><strong>&#8220;The genetic continuity we see suggests that some populations in this region remained isolated for tens of thousands of years.&#8221;<\/strong><\/p>\n<\/blockquote>\n<p><span>The genomes of the Takarkori individuals indicate that their ancestors split from other human populations around the same time that early <\/span><em>Homo sapiens<\/em><span> left Africa roughly 50,000 years ago. Instead of dispersing into Eurasia, these early North Africans appear to have remained genetically distinct, forming a population that persisted in relative isolation well into the Holocene.<\/span><\/p>\n<p>This ancient group shares ancestry with the 15,000-year-old foragers of Taforalt Cave in Morocco, associated with the Iberomaurusian culture. However, both populations appear equally distant from sub-Saharan African groups, challenging previous theories that the Green Sahara served as a genetic bridge between sub-Saharan and North African populations.<\/p>\n<blockquote>\n<p><strong>&#8220;Despite the Sahara\u2019s transformation into a lush, habitable landscape, gene flow between sub-Saharan and North African groups remained minimal,&#8221;<\/strong><span> said Johannes Krause, a senior author of the study. <\/span><strong>&#8220;This contradicts the long-held assumption that the African Humid Period facilitated large-scale genetic mixing across the continent.&#8221;<\/strong><\/p>\n<\/blockquote>\n<p>Another striking discovery concerns the presence of Neandertal DNA in the Takarkori individuals. While they carry significantly less Neandertal ancestry than non-Africans, they still show slightly higher levels than contemporary sub-Saharan Africans. This suggests limited genetic exchange between early North African populations and Eurasian groups that interbred with Neandertals before returning to Africa.<\/p>\n<blockquote>\n<p><strong>&#8220;Our findings indicate that early North Africans were largely isolated, yet they received small amounts of Neandertal DNA from interactions with groups outside of Africa,&#8221;<\/strong><span> Krause noted.<\/span><\/p>\n<\/blockquote>\n<div class=\"captioned-image-container\">\n<figure><a class=\"image-link image2 is-viewable-img\" target=\"_blank\" href=\"https:\/\/substackcdn.com\/image\/fetch\/f_auto,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp\" data-component-name=\"Image2ToDOM\" rel=\"\"><\/p>\n<div class=\"image2-inset\"><picture><source type=\"image\/webp\" srcset=\"https:\/\/substackcdn.com\/image\/fetch\/w_424,c_limit,f_webp,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp 424w, https:\/\/substackcdn.com\/image\/fetch\/w_848,c_limit,f_webp,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp 848w, https:\/\/substackcdn.com\/image\/fetch\/w_1272,c_limit,f_webp,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp 1272w, https:\/\/substackcdn.com\/image\/fetch\/w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp 1456w\" sizes=\"100vw\"\/><img decoding=\"async\" src=\"https:\/\/substackcdn.com\/image\/fetch\/w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp\" width=\"824\" height=\"617\" data-attrs=\"{&quot;src&quot;:&quot;https:\/\/substack-post-media.s3.amazonaws.com\/public\/images\/b5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp&quot;,&quot;srcNoWatermark&quot;:null,&quot;fullscreen&quot;:null,&quot;imageSize&quot;:null,&quot;height&quot;:617,&quot;width&quot;:824,&quot;resizeWidth&quot;:null,&quot;bytes&quot;:160994,&quot;alt&quot;:null,&quot;title&quot;:null,&quot;type&quot;:&quot;image\/webp&quot;,&quot;href&quot;:null,&quot;belowTheFold&quot;:true,&quot;topImage&quot;:false,&quot;internalRedirect&quot;:&quot;https:\/\/www.anthropology.net\/i\/160462614?img=https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp&quot;,&quot;isProcessing&quot;:false}\" class=\"sizing-normal\" alt=\"\" srcset=\"https:\/\/substackcdn.com\/image\/fetch\/w_424,c_limit,f_auto,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp 424w, https:\/\/substackcdn.com\/image\/fetch\/w_848,c_limit,f_auto,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp 848w, https:\/\/substackcdn.com\/image\/fetch\/w_1272,c_limit,f_auto,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp 1272w, https:\/\/substackcdn.com\/image\/fetch\/w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep\/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb5760ba9-4420-4739-a865-b4a63e8f3027_824x617.webp 1456w\" sizes=\"auto, 100vw\" loading=\"lazy\"\/><\/picture><\/div>\n<p><\/a><figcaption class=\"image-caption\">View of the Takarkori rock shelter in Southern Libya. \u00a9 Archaeological Mission in the Sahara, Sapienza University of Rome<\/figcaption><\/figure>\n<\/div>\n<p>The study also provides new insights into the origins of pastoralism in the region.
