Picture shows what scientists say are Neanderthal cave-paintings inside the Andalusian cave of Ardales, on March 1, 2018. The cave-paintings, found in three caves in Spain, were created between 43,000 and 65,000 years ago, at least 20,000 years before modern humans are believed to have arrived in Europe.
