Fig. 1: The geographical distribution and the maximum clade credibility tree with a divergence time of the Kra-Dai languages.
From: Phylogenetic evidence reveals early Kra-Dai divergence and dispersal in the late Holocene

a The geographical distribution of 100 Kra-Dai language samples and the language phyla in South China and Mainland Southeast Asia. The base map was derived from an R package rnaturalearth (URL: https://github.com/ropensci/rnaturalearth). b The maximum clade credibility tree was shown with posterior values. The clades were collapsed by language groups. Each language branch was assigned with a specific color. c The bar plot was shown for the 95% highest posterior density (HPD) for the divergence time estimations of six Proto languages in Kra-Dai languages. Data were derived from an MCMC run of 9000 posterior samples (more details see Fig. S5b and Supplementary Data 9). Proto-Kra-Dai (unit: years BP): min = 2158, max = 9023, mean = 4041, 95% HPD = 2741–5550; Proto-Kra: min = 1625, max = 3317, mean = 2435, 95% HPD = 1967–2909; Proto-Hlai: min = 291, max = 3000, mean = 1155, 95% HPD = 443–2035; Proto-Ong-Be: min = 803, max = 2713, mean = 1750, 95% HPD = 1299–2226; Proto-Kam-Sui: min = 896, max = 1579, mean = 1222, 95% HPD = 1044–1410; Proto-Tai: min = 592, max = 2200, mean = 1360, 95% HPD: 873–1903.
