Finger painting is a staple of modern preschool curriculum, but did you know that finger painting also might have been a feature of daycare centers in prehistoric times? Archaeologists have discovered 13,000-year-old finger paintings (or finger flutings, if you want to get technical about it) in a cave in France that are believed to have been produced by children aged 3 to 7. Finger paintings were found in every room of the five-mile Cave of the Hundred Mammoths, but one room contained much more finger fluting than the others, suggesting to archaeologists that it might have been a play room for children.
