It’s no Mona Lisa, but a smudged red disk in northern Spain has been crowned the world’s earliest cave painting. Dated to more than 40,800 years ago, the shape was painted by some of the first modern humans to reach the Iberian Peninsula — or it may have been done by Neanderthals, residents of the Iberian peninsula for more than 200,000 years.
“There is a very good chance that this is Neanderthal,” says Alistair Pike, an archaeological scientist at the University of Bristol, UK, whose team dated dozens of paintings in 11 caves in northern Spain. But Lawrence Guy Straus, an expert on the caves who is based at the University of New Mexico in Albuquerque, calls that “a pretty wild speculation,” because it is based on a single date that could overlap with human occupation.
