The Oldest Chinese Script?

Didi Tang, "5,000-year-old primitive writing generates debate in China", The Associated Press July 11, 2013:

Archeologists say they have discovered some of the world's oldest known primitive writing, dating back 5,000 years, in eastern China, and some of the markings etched on broken axes resemble a modern Chinese character. The inscriptions on artifacts found south of Shanghai are about 1,400 years older than the oldest written Chinese language. Chinese scholars are divided over whether the markings are words or something simpler, but they say the finding will shed light on the origins of Chinese language and culture. The oldest writing in the world is believed to be from Mesopotamia, dating back slightly more than 5,000 years. Chinese characters are believed to have been developed independently. Inscriptions were found on more than 200 pieces dug out from the Neolithic-era Liangzhu relic site. The pieces are among thousands of fragments of ceramic, stone, jade, wood, ivory and bone excavated from the site between 2003 and 2006, lead archeologist Xu Xinmin said. More here....
