Earlier Neandertal demise suggested by redating using more precise carbon dating

Earlier Neandertal demise suggested by redating using more precise carbon dating | Vloasis sci-tech | Scoop.it

The story of the Neandertals may need a new ending, a controversial study suggests. Using improved radiocarbon methods, scientists redated two of the youngest known Neandertal cave sites and concluded that they are at least 10,000 years older than previous studies have found.

 

The findings cast doubt on the reliability of radiocarbon dates from other recent Neandertal sites, the researchers suggest online February 4, 2013, in the Proceedings of the National Academy of Sciences. This means the last Neandertals might have died out much earlier than previously thought, which could cause anthropologists to rethink how and why these hominids vanished. Researchers have long debated whether the harsh Ice Age climate, the appearance of modern humans migrating out of Africa, or some other factor drove Neandertals to extinction.

 

“The paper is simply excellent,” says archaeologist Olaf Jöris of the Romano-Germanic Central Museum in Mainz, Germany. The new research supports Jöris’ own review of Neandertal dates, in which he concluded that the most-recent Neandertals probably lived around 42,000 years ago. The standard view suggests that the last of these hominids occupied Europe as recently as about 28,000 years ago.

 

But other archaeologists are not convinced by the new work. “We shouldn’t get too carried away over results that amount to a few radiocarbon dates from two sites,” says Paul Pettitt, an archaeologist at Durham University in England.

ENLARGE This Neandertal jaw from a cave in southern Spain may be at least 10,000 years older than previously estimated, a new dating analysis suggests. 

Over the last couple of decades, archaeologists have determined that the Iberian Peninsula was one of the last Neandertal refuges. Neandertals throughout much of Europe appear to have gone extinct around the same time that modern humans reached the continent, at least 42,000 years ago. But the favorable climate of southern Spain and Gibraltar may have helped Neandertals hang on in for another 10,000 years or so. Getting a precise chronology is crucial to understanding what factors played a role in the Neandertals’ demise and the degree to which Neandertals and humans interacted and possibly interbred, researchers say.
