Pottery 20,000 years old found in a Chinese cave
Baku, June 30 (AZERTAC). Pottery fragments found in a south China cave have been confirmed to be 20,000 years old, making them the oldest known pottery in the world, archaeologists say.
The findings, which will appear in the journal Science on Friday, add to recent efforts that have dated pottery piles in east Asia to more than 15,000 years ago, refuting conventional theories that the invention of pottery correlates to the period about 10,000 years ago when humans moved from being hunter-gathers to farmers.
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.
He said the disconnection between pottery and agriculture as shown in east Asia might shed light on specifics of human development in the region.
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."
The ancient fragments were discovered in the Xianrendong cave in south China`s Jiangxi province, which was excavated in the 1960s and again in the 1990s, according to the journal article.
Wu, a chemist by training, said some researchers had estimated that the pieces could be 20,000 years old, but that there were doubts.
Scientists took samples, such as bones and charcoal, from above and below the ancient fragments in the dating process, Wu said.
"This way, we can determine with precision the age of the fragments, and our results can be recognized by peers," Wu said.
Shelach said he found the process done by Wu`s team to be meticulous and that the cave had been well protected throughout the research.
The same team in 2009 published an article in the Proceedings of the National Academy of Sciences, in which they determined the pottery fragments found in south China`s Hunan province to be 18,000 years old, Wu said.
"The difference of 2,000 years might not be significant in itself, but we always like to trace everything to its earliest possible time," Wu said. "The age and location of pottery fragments help us set up a framework to understand the dissemination of the artifacts and the development of human civilization."
