在泰国，山地部落一词用于描述其成员传统上从事刀耕火种农业并居住在山区的人口。这些部落被认为已经在亚洲各地迁移了长达5,000年，包括通过中国南部和/或东南亚的迁移。大约在过去的一千年里，从中国到泰国的移民一直在不断地向南迁移，目前任何一个部落的地理范围都跨越了多个政治边界。由于这些人口中没有一个有本地文字，直到最近，书面历史都是外部制作的。有人提出山地部落起源于北方亚洲、西藏和西伯利亚。他们都主张近亲结婚，语言不通。为了检验关于这些群体的地理起源、它们与邻近群体之间的亲缘关系和迁移以及它们的遗传关系是否与它们的语言关系相对应的假设，我们分析了来自5个泰国山地部落群体的118个个体的2445个全基因组SNP标记（Akha，Hmong，Karen，Lahu，and Lisu），90个来自大多数泰国人群的个体，以及826个来自亚洲和大洋洲HGDP和HapMap人群的个体。考虑到这些结果的背景下，最近的大规模研究结果的亚洲地理遗传变异，使我们能够推断出一个共同的东南亚起源的这五个山地部落人口以及祖先的组成部分，区分他们看到在连续的聚类水平。此外，推断出的山地部落之间的共同祖先的水平很好地对应于他们的语言之间的关系。
In Thailand, the term Hill Tribe is used to describe populations whose members traditionally practice slash and burn agriculture and reside in the mountains. These tribes are thought to have migrated throughout Asia for up to 5,000 years, including migrations through Southern China and/or Southeast Asia. There have been continuous migrations southward from China into Thailand for approximately the past thousand years and the present geographic range of any given tribe straddles multiple political borders. As none of these populations have autochthonous scripts, written histories have until recently, been externally produced. Northern Asian, Tibetan, and Siberian origins of Hill Tribes have been proposed. All purport endogamy and have non-mutually intelligible languages. In order to test hypotheses regarding the geographic origins of these populations, relatedness and migrations among them and neighboring populations, and whether their genetic relationships correspond with their linguistic relationships, we analyzed 2445 genome-wide SNP markers in 118 individuals from five Thai Hill Tribe populations (Akha, Hmong, Karen, Lahu, and Lisu), 90 individuals from majority Thai populations, and 826 individuals from Asian and Oceanean HGDP and HapMap populations using a Bayesian clustering method. Considering these results within the context of results of recent large-scale studies of Asian geographic genetic variation allows us to infer a shared Southeast Asian origin of these five Hill Tribe populations as well ancestry components that distinguish among them seen in successive levels of clustering. In addition, the inferred level of shared ancestry among the Hill Tribes corresponds well to relationships among their languages.
