The research by a team of Chinese and American scientists also pushes the emergence of pottery back to the last ice age, which might provide new explanations for the creation of pottery, said Gideon Shelach, chair of the Louis Frieberg Center for East Asian Studies at The Hebrew University in Israel.
“The focus of research has to change,” Shelach, who is not involved in the research project in China, said by telephone.

Wu Xiaohong, professor of archaeology and museology at Peking University and the lead author of the Science article that details the radiocarbon dating efforts, told The Associated Press that her team was eager to build on the research.
“We are very excited about the findings. The paper is the result of efforts done by generations of scholars,” Wu said. “Now we can explore why there was pottery in that particular time, what were the uses of the vessels, and what role they played in the survival of human beings.”
