Bulgarian archaeologist Georgi Ganetsovski shows a seventh millennium BC human skeleton discovered in excavation works near the town of Vratsa, some 120 km north form the capital Sofia, November 13, 2004. Archaelogists believe the skeleton is of a woman from the monochrome neolith era, the earliest stage of the new-stone age. The body was buried in a crouching pose, called "hocker", facing the direction of the sun. REUTERS/Stoyan Nenov SN/JV
