Thanks SteveH. Sound like the Chinese agitprop machine churning out more BS. Decades ago a piece of fired pottery from that culture was found with the potter's fingerprints intact. One of the Chinese supervisors (non-scientists who monitor any international presencee in archaeology in China) asked if it were possible to determine ethnicity from fingerprints. "I don't know" came the response of the foreign science writer, and the artifact basically disappeared.
