French cave tells new story about Neanderthals, early humans

A hillside dwelling overlooking the picturesque Rhone Valley in southern France proved irresistible for our ancestors, attracting both Neanderthals and modern humans long before the latter were thought to have reached that part of Europe, a new study suggests.

In a paper published on Feb. 10 by the journal Science Advances, researchers from Europe and the United States described finding fossilized homo sapiens remains and tools sandwiched between those of Neanderthals in the Mandrin Grotto, named after an 18th-century French folk hero.

"The findings provide archaeological evidence that these hominin cousins may have coexisted in the same region of Europe during the same time period," the team said.

Using new techniques, the authors dated some of the human remains to about 54,000 years ago, almost 10,000 years earlier than previous finds in Europe, with one exception in Greece.

"This significantly deepens the known age of the colonization of Europe by modern humans," said Michael Petraglia, an expert on prehistory at Germany's Max Planck Institute for the Science of Human History.

Petraglia, who was not involved in the study, said it had major implications for understanding the spread of modern humans and our interactions with the Neanderthals.

The researchers said they spent more than 30 years carefully sifting through layers of dirt inside the cave, which is 140 kilometers north of the French Mediterranean city of Marseille. They discovered hundreds of thousands of artifacts that they were able to attribute to either Neanderthals or modern humans. These included advanced stone tools known as "points" that were used by homo sapiens, our closest ancestors, to cut or scrape and as spear tips.
