Imagine stumbling upon ancient graffiti from both Neanderthals and modern humans—on opposite sides of the Strait of Gibraltar! Researchers just found the world’s first intercontinental rock art collection, showing both species left their mark in caves in Spain and Morocco. Some of these hand stencils are 64,000 years old! The coolest part? They might’ve used the same pigments and styles, hinting at a shared artistic tradition. These sites are now up for protected status—talk about a legacy! #History #Archaeology #Neanderthals
