Last Neanderthals near the Arctic Circle ?

Remains found near the Arctic Circle in May 2011 are characteristic of the Mousterian culture and have recently been dated at over 28,500 years old, which is more than 8,000 years after Neanderthals are thought to have disappeared.

The Ural Mountains site “may be one of the last refuges of the Neanderthals, and that would be very exciting,” said study leader Ludovic Slimak, an archaeologist at France’s Université de Toulouse le Mirail. This unexpected discovery by an international multi-disciplinary team, including researchers from CNRS, challenges previous theories. Could Neanderthals have lived longer than thought? Or had Homo sapiens already migrated to Europe at that stage? The results were published in Science, 13 May 2011.

This culture is considered to be archaic, and not sufficiently advanced to allow Neanderthals to settle in the most extreme northern climates. It is thought to have brought about their demise some 33,000 to 36,000 years ago. They seem to have made way for modern humans, who appear to have occupied the whole of Eurasia thanks to their mastery of more advanced technologies.

Dating of butchery marks crucial

A multi-disciplinary team of French CNRS researchers, working with Norwegian and Russian scientists, studied the Byzovaya site in the Polar Urals in northern Russia. Using carbon 14 dating and an optical simulation technique, the team was able to put an accurate date on sediments and on mammoth and reindeer bones abandoned on the site. The bones bore traces of butchering by Mousterian hunters.

The results intrigue scientists in more ways than one. They show that Mousterian culture may have lasted longer than scientists had originally thought. What’s more, no Mousterian presence had ever been identified so close to the Arctic Circle. All other traces are at least 1000 km further south. Lastly, the Byzovaya site, in Eurasia, seems only to have been occupied once, approximately 28,500 years ago, which is over 8,000 years after Neanderthals were thought to have disappeared...
