Archivo: The origin and spread of the Sino-Tibetan language family

Description: Despite its importance, many studies have not been conducted on the Sino-Tibetan languages, so there have been many questions and debates about the origin and spread route. So in 2019, Laurent Sagart and other researchers used the latest scientific techniques based on the newly developed database to derive the origin and spread route of the Sino-Tibetan languages. 1. Researchers develop a database of comparative linguistic data, and apply the linguistic comparative method to identify sound correspondences and establish cognates. 2. Researchers use phylogenetic methods to infer the relationships among these languages and estimate the age of their origin and homeland. 3. Reserchers concluded that Sino-Tibetan originated with north Chinese millet farmers around 7200 B.P. and suggest a link to the late Cishan and the early Yangshao cultures.
