Rice was first domesticated in the region of the Yangtze river valley.Morphological studies of rice phytoliths from the Diaotonghuan archaeological site clearly show the transition from the collection of wild rice to the cultivation of domesticated rice. The large number of wild rice phytoliths at the Diaotonghuan level dating from 12,000-11,000 BP indicates that wild rice collection was part of the local means of subsistence.
