GIBRALTAR, Sept. 2 (UPI) -- Neanderthals have gotten a bad rap. Informally, the now extinct human species Homo neanderthalensis is thought of as a bunch of babbling, rock-bashing meatheads. But more and more evidence suggests they were likely more sophisticated. Most recently, a piece of Neanderthal cave art was found in Gibraltar -- further evidence that modern Homo sapiens have been underestimating their ancestors intelligence.
The 39,000-year-old artwork -- found in Gorham's cave, overlooking the Mediterranean -- is little more than a series of criss-crossing lines, a sort of Neanderthal Twitter hashtag. But researchers say it's artwork, nonetheless -- deliberate and intelligent.
