Spanish Cave Paintings the Oldest Yet

New tests on prehistoric Spanish cave paintings are pushing them back into Neanderthal territory.

Testing the coating of paintings in 11 Spanish caves, researchers found that one is at least 40,800 years old, which is at least 15,000 years older than previously thought. That makes them older than the more famous French cave paintings by thousands of years.

That is thousands of years older than the paintings at Chauvet Cave, for example. Some researchers are starting to speculate that Neanderthal people, who are not thought as having "art," may have made them.
