Photo: Stone Age Rice Fields Discovered in China Swamp



A reconstructed hut at the ancient Chinese settlement of Hemdu may resemble the elevated structures used by the first known rice farmers some 7,700 years ago, scientists say.

A new study of artifacts and sediments found at Kuahuqiao, China, show that Stone Age farmers there used fire and even flood control to develop the earliest rice paddies ever found.
