Prehistoric Children Finger-Painted on Cave Walls

"As many exasperated parents have discovered, kids like to draw on walls. It turns out they’ve been doing it since the Stone Age, in some cases with the help and encouragement of grown-ups. Researchers have uncovered evidence that children as young as 2 decorated France’s Rouffignac caves with markings known as finger flutings at least 13,000 years ago, drawing not only simple lines but also symbolic shapes. The most prolific budding artist, thought to have been a 5-year-old girl, braved the pitch-dark caverns’ rocky terrain to hone her craft on high, remote corners—perched, perhaps, on the shoulders of an approving adult."
