Analysis reveals distinct evolution patterns for languages and weaving technologies among Kra-Dai peoples, suggesting connections with their diaspora.
We investigate and compare the evolution of two aspects of culture, languages and weaving technologies, amongst the Kra-Dai (Tai-Kadai) peoples of southwest China and southeast Asia, using Bayesian Markov-Chain Monte Carlo methods to uncover phylogenies. The results show that languages and looms evolved in related but different ways, and bring some new insights into the diaspora of the Kra-Dai speakers across southeast Asia. We found that the languages and looms used by Hlai speakers of Hainan are outgroups in both linguistic and loom phylogenies, and that the looms used by speakers of closely related languages tend to belong to similar types. However, we also found discrepancies at a deep level between linguistic subgroups and loom types, in particular among widely dispersed South-Western Tai speakers, and we discuss possible reasons for this.
