New dates rewrite Neanderthal story. Modern humans and Neanderthals co-existed in Europe 10 times longer than previously thought, a study suggests.

New dates rewrite Neanderthal story

The most comprehensive dating of Neanderthal bones and tools ever carried out suggests that the two species lived side-by-side for up to 5,000 years. The new evidence suggests that the two groups may even have exchanged ideas and culture, say the researchers. The study has been published in the journal Nature. Until now, Neanderthal remains have been dated by a number of laboratories but many have been considered unreliable. Now an international team of researchers collected more than 400 samples from the most important sites in Europe. Ancient 'Evil Eye' Box Discovered In Nile River Cemetery.
