Prehistoric rock art in Australia’s Kimberly is famed for its age – it was painted between 70,000 and 46,000 years ago! But the paint itself is much, much younger. Wait, what? How can the paint be younger than the painting? Well, a new study found the vibrant artworks were colonized by colorful microbes, which serve as “living pigments” in the paintings. The colors we see today are direct descendants of the first founders, who grew where the original paints provided nutrients.
