 The politicization of archaeology is also problematic, particularly erroneous reconstructions among some Chinese archaeologists of non-Sinitic sites as Han.Some authors favoring the "Out of Sundaland" model like William Meacham, reject the southern Chinese mainland origin of pre-Austronesians entirely.Nevertheless, based on linguistic, archaeological, and genetic evidence, Austronesians are most strongly associated with the early farming cultures of the Yangtze River basin that domesticated rice from around 13,500 to 8,200 BP.
