FUZHOU Patrick Ewing Knicks Jersey , Nov. 5 (Xinhua) -- Chinese archaeologists have found a large amount of carbonized rice grains in caves dating from the New Stone Age, challenging the conventional view that cave dwellers were solely hunter gathers and did not cultivate land for food.
More than 10,000 grains were discovered at the No. 4 cave in the Nanshan ruins in east China's Fujian Province, which dates back 5,300 to 4 Michael Beasley Knicks Jersey ,300 years.
At an ongoing international conference on prehistoric archaeology being held in Fujian, the archaeological team announced that this is the first cave-dwelling agrarian society ever found in China.
The finding is also rare worldwide, said Zhao Zhijun, a member of the team and also from the Institute of Archaeology of the Chinese Academy of Social Sciences.
The grains are believed to have been grown by the Nanshan cave dwellers, rather than being obtained by other means Mark Jackson Knicks Jersey , because many farmland weeds were also found along with the grains, according to Zhao.
The team's studies on the remains of the cave-dwellers showed that they suffered dental cavities and other oral diseases that are common among humans in agrarian societies, said Wang Minghui, another team member and researcher with the institute.
"It further proves that Nanshan residents mastered some agricultural techniques," Wang said.
The finding has raised the question why the Nanshan ancestors continued to live in caves after beginning farming. It is traditionally believed that humans in agrarian societies would move from caves to more spacious homes due to explosive population growth.
"The Nanshan finding offers a new perspective for prehistoric study. We must consider more possibilities when talking about where our ancestors lived and what they lived on Kristaps Porzingis Knicks Jersey ," Zhao said.
Excavation of the Nanshan ruins started in 2012. Scores of caves, thousands of items made from pottery, stone and bones, as well as eight tombs and two reservoirs, have been found at the site.

Distraught children laid floral tributes at a Sydney school on Wednesday after two 8-year-old boys were killed by a car that smashed into their classroom, as the driver expressed her deep sorrow over the tragedy.
The incident unfolded at the Banksia Road Public School on Tuesday when the car plowed into a wooden classroom building with 24 students inside.
Two boys bore the brunt of the impact and died, while three young girls are fighting for their lives, leaving the community in shock.
The 52-year-old woman driver Joakim Noah Knicks Jersey , Maha Al-Shennag, has been charged with two counts of dangerous driving causing death and with negligent driving.
Police have indicated the crash was being treated as non-intentional.
Her lawyer Nick Hanna told the Sydney Daily Telegraph she was "deeply sorry for the loss and hurt suffered by the children, the school, the families and the community."
Al-Shennag, reportedly a widowed mother-of-four who was dropping off a child at the school Frank Ntilikina Knicks Jersey , has had her license suspended. She was bailed to appear in court on November 29.
The school opted to open as usual on Wednesday, with counselors on hand to support returning children, many in tears as tributes, flowers and teddy bears were left at the school gates.
"I cannot begin to comprehend the sadness being felt by the parents and families of the two young boys who have died in the tragic accident at Banksia Road Public School," New South Wales state Education Minister Rob Stokes said. "My thoughts and prayers are with their families and the entire school community."
A local shopkeeper Enes Kanter Knicks Jersey , who did not want to be named, said she knew the dead boys.
"They would come into our shop wanting lollies and playing games," she told AFP. "It has affected every single person we know. As a shop owner, and customers coming in and out, everyone is talking about it Doug McDermott Knicks Jersey , it is really, really devastating."
