Interesting article in the Science Times about one of the oldest civilizations in the world - what's new is that enough has been found to categorize it as a civilization - in the Balkans. It's referred to as Old Europe. The architectural model above (some of their structures did indeed have two stories) dates from 4600-3900 BCE, the pot below (with patterns remarkably like those of Pueblo pots!) from 3700-3500 BCE.
