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.
While other methods of dating have longer ranges, they generally date the sediments in which items are found, not the items themselves.
In 2014, a team sequenced a DNA from a femur found at another site in southern Siberia and determined that it belonged to a modern human who lived about 45,000 years ago, establishing that our species was in the region by that time, if not earlier.) One team obtained 50 radiocarbon dates from material collected from areas that were not previously disturbed.
The material included charcoal and artifacts, such as deer and elk teeth that had been modified by hominins.
Nestled in the foothills of southern Siberia’s Altai Mountains, Denisova Cave has yielded numerous artifacts, as well as fossils of many animals and at least two hominins: Neanderthals and Denisovans.
The cave is the only place in the world known to have remains of the Denisovans, who, like Neanderthals, were our close evolutionary cousins.
