| Abstract: |
In 1992 the flotation of carbonised materials from Lilou, a Longshan Culture site in Henan Province, yielded the first carbonised remains of prehistoric rice from northern China. But it is often forgotten that from as early as 1921 impressions of ancient rice have been found embedded in pottery in many northern sites, suggesting rice was cultivated there from as early as 7500 BP. The origin of domesticated rice in China was probably further south in the Yangzi Valley, where it is known from an even earlier period.
