The a DNA studies from cave’s hominins, both Denisovan and Neanderthal, helped confirm that both populations have, at various times, interbred with and each other.

The fossils are arranged by approximate age as determined by radiometric dating and/or incremental dating and the species name represents current consensus; if there is no clear scientific consensus the other possible classifications are indicated.

Most of the early fossils shown are not considered direct ancestors to Homo sapiens but are closely related to direct ancestors and are therefore important to the study of the lineage.

The site is one of the most significant for understanding human evolution, but study of it has been hampered by difficulty dating the finds.

Today, a pair of papers reveal new Denisovan fossils, scores of new dates and a refined timeline for a hominin presence at the cave: important steps in untangling the complicated role it has played in the human story.

(Right about now, you may be wondering whether fossils have been found at Denisova Cave from the same time periods as Neanderthal and Denisovan remains, though hominin remains at the site are generally fragmentary and many remain unstudied.

Some researchers have attributed a few of the artifacts from the site to modern humans based on style.

The researchers were part of a team that created a new and more refined timeline of both Neanderthals and Denisovans at the site.

Order from Chaos In the studies published today, two teams took different approaches to untangling the cave’s complicated setting and establishing a more precise timeline for Denisovans and Neanderthals at the site.

The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.
