在公元13世纪来自中国南方的说泰语的人到来之前，说孟高棉语的人居住在泰国北方。历史和人类学证据表明，孟高棉人群体与当今大多数北方泰国人群体之间有着密切的关系。在这项研究中，线粒体和Y染色体DNA多态性超过800名志愿者从8个孟高棉语和10个台语人口进行了调查，以估计这些主要的语言群体和他们的内部结构之间的遗传差异的程度。大部分的遗传变异是在种群内观察到的（mtDNA和Y染色体分别约为80%和90%）。群体间的遗传差异在孟高棉语群体中比在泰语群体中高得多，特别是在父系遗传标记上。这两个主要的语言群体在遗传上是不同的，但只占总遗传变异的一小部分（1%至2%）。种群间的遗传距离与其语言差异相关，而地理距离不能解释遗传分化模式。泰国北方的孟高棉语人群在相互之间以及与泰语人群相比时表现出遗传差异。不同的漂移效应和婚后居住模式之间的两个语言群体是一个小的，但显着的一部分，它们之间的遗传变异模式的解释。
The Mon-Khmer speaking peoples inhabited northern Thailand before the arrival of the Tai speaking people from southern China in the thirteenth century A.D. Historical and anthropological evidence suggests a close relationship between the Mon-Khmer groups and the present day majority northern Thai groups. In this study, mitochondrial and Y-chromosomal DNA polymorphisms in more than 800 volunteers from eight Mon-Khmer and ten Tai speaking populations were investigated to estimate the degree of genetic divergence between these major linguistic groups and their internal structure. A large fraction of genetic variation is observed within populations (about 80% and 90% for mtDNA and the Y-chromosome, respectively). The genetic divergence between populations is much higher in Mon-Khmer than in Tai speaking groups, especially at the paternally inherited markers. The two major linguistic groups are genetically distinct, but only for a marginal fraction (1 to 2%) of the total genetic variation. Genetic distances between populations correlate with their linguistic differences, whereas the geographic distance does not explain the genetic divergence pattern. The Mon-Khmer speaking populations in northern Thailand exhibited the genetic divergence among each other and also when compared to Tai speaking peoples. The different drift effects and the post-marital residence patterns between the two linguistic groups are the explanation for a small but significant fraction of the genetic variation pattern within and between them.
