Neanderthals' engravings found 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 engravings were made at least 57,000 years ago when the cave became sealed off, and all stone tools within the cave are Mousterian, a style associated with Neanderthals.
