Rates of Evolution in Ancient DNA from Adélie Penguins
Well-preserved subfossil bones of Adélie penguins,Pygoscelis adeliae, underlie existing and abandoned nesting colonies in Antarctica. These bones, dating back to more than 7000 years before the present, harbor some of the best-preserved ancient DNA yet discovered. From 96 radiocarbon-aged bones, we...
