In support of both the Austric and Austro-Tai hypothesis, Robert Blust connects the lower Yangtze Neolithic Austro-Tai entity with the rice-cultivating Austroasiatic cultures; assuming the center of East Asian rice domestication, and putative Austric homeland, to be located in the Yunnan/Burma border area, instead of the Yangtze River basin as is currently accepted. Under that view, there was an east–west genetic alignment, resulting from a rice-based population expansion, in the southern part of East Asia: Austroasiatic-Kra-Dai-Austronesian, with unrelated Sino-Tibetan occupying a more northerly tier. Depending on the author, other hypotheses have also included other language families like Hmong-Mien and even Japanese-Ryukyuan into the larger Austric hypothesis.
