How far back in time can we trace them? How extensive was their territory? When did Denisovans and Neanderthals become extinct and was this linked to the presence of modern humans in the regions they occupied? How common was gene flow between the three hominin groups? What is the archaeological signature (toolkit) of the Denisovans, and how distinct is it from tools produced by Neanderthals and early modern humans?<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"p1\">Ultimately, the goal is to expand our understanding of early modern humans, Neanderthals and Denisovans, and further reveal their exact geographic range, age, genetic variability and archaeological signature.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"p1\">The <a href=\"https:\/\/finderc.org\/index.php\/archaeological-themes\/\">archaeological themes<\/a> we work on, and the <a href=\"https:\/\/finderc.org\/index.php\/scientific-methods\/\">scientific methodologies<\/a> we use to investigate these topics, are outlined in the next few pages.<\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The period between 200,000-50,000\u00a0 years ago is crucial in human evolution.
