  • Beschreibung: <jats:title>Founder effects in modern populations</jats:title> <jats:p> The genomes of ancient humans can reveal patterns of early human migration (see the Perspective by Achilli <jats:italic>et al.</jats:italic> ). Iceland has a genetically distinct population, despite relatively recent settlement (∼1100 years ago). Ebenesersdóttir <jats:italic>et al.</jats:italic> examined the genomes of ancient Icelandic people, dating to near the colonization of Iceland, and compared them with modernday Icelandic populations. The ancient DNA revealed that the founders had Gaelic and Norse origins. Genetic drift since the initial settlement has left modern Icelanders with allele frequencies that are distinctive, although still skewed toward those of their Norse founders. Scheib <jats:italic>et al.</jats:italic> sequenced ancient genomes from the Channel Islands of California, USA, and Ontario, Canada. The ancient Ontario population was similar to other ancient North Americans, as well as to modern Algonquian-speaking Native Americans. In contrast, the California individuals were more like groups that now live in Mexico and South America. It appears that a genetic split and population isolation likely occurred during the Ice Age, but the peoples remixed at a later date. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6392" page="1028" related-article-type="in-this-issue" vol="360" xlink:href="10.1126/science.aar2625">1028</jats:related-article> , p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6392" page="1024" related-article-type="in-this-issue" vol="360" xlink:href="10.1126/science.aar6851">1024</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6392" page="964" related-article-type="in-this-issue" vol="360" xlink:href="10.1126/science.aat7257">964</jats:related-article> </jats:p>
