Oldest Neanderthal engravings discovered in French cave.

Lines, swirls, and dots on the walls of a cave in France are the oldest known engravings by Neanderthals, according to a new analysis of the ancient marks. Researchers believe the markings "demonstrate a deliberate creative process." The finding adds to a growing body of evidence that Neanderthals were creative beings and more complex than the stereotype suggests. The researchers made detailed 3D models of the engravings from photographs of the Loire Valley's La Roche-Cotard cave using a process known as photogrammetry.
