Lab Notes: The oldest rock art in the world…that we know of

A faint orange hand stencil on the wall of a cave in Indonesia just became the oldest art known to science. The art, made by splattering ochre over a hand, had been painted over by subsequent generations and was only preserved because moisture combined with the limestone of the cave to form a protective layer on top. The finding strengthens the picture that humans migrated via Borneo, Sulawesi and Papua to reach Australia at least 65,000 years ago.
