U-th dating of carbonate on top of Iberian cave art and the underlying wall allows researchers to obtain a maximum and minimum age constraint.


The oldest minimum samples for all caves predate the arrival of modern humans by 20 kya, when Neandertals exclusively populated Iberia.


Evidence of Neanderthal populations using premeditated creation and hand placement suggests the origins of symbolic behavior and human symbolism.
