Neanderthals were cave artists, researchers find

Some of the oldest cave art found in modern-day Spain is too old to have been made by modern humans, researchers reported Thursday.
The paintings of animals, hand stencils and other drawings must have been made by Neanderthals, the team reports in the journal Science.
And Neanderthals were at it for a long time: the cave art spans a period of 25,000 years, the team of European researchers said.
