New dates rewrite Neanderthal story

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

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.
