目前在西藏高原土生土长的家猪应该是在现代西藏人的祖先持续的殖民时期引入的。然而，没有直接的遗传证据表明藏猪的本地起源或外来迁移。我们分析了来自7个藏猪群体的218个个体的mtDNA高变片段I（HVI）变异和来自亚洲家猪和野猪的1，737个报道的mtDNA序列。贝叶斯共识树揭示了一个主要的单倍群M和12个次要的单倍群，这表明了大量的小规模原位驯化事件。特别是，单倍群D1和D6代表了两个高度分歧的谱系在西藏高原和岛屿东南亚，分别。单倍群M的网络分析进一步揭示了一个主要的亚单倍群M1和两个次要的亚单倍群M2和M3。有趣的是，M2主要分布在东南亚，这表明它是一个本地起源。与单倍群D6相似，M3主要分布于东南亚岛屿。这种模式表明，东南亚岛屿，而不是东南亚，可能是以前研究中描述的所谓太平洋分支（M3和D6）的驯化中心。多样性梯度分析表明，M1主要亚群分别起源于东南亚、长江中下游和青藏高原。我们确定了两个新的起源中心的家猪在西藏高原和东南亚地区的岛屿。
The domestic pig currently indigenous to the Tibetan highlands is supposed to have been introduced during a continuous period of colonization by the ancestors of modern Tibetans. However, there is no direct genetic evidence of either the local origin or exotic migration of the Tibetan pig. We analyzed mtDNA hypervariable segment I (HVI) variation of 218 individuals from seven Tibetan pig populations and 1,737 reported mtDNA sequences from domestic pigs and wild boars across Asia. The Bayesian consensus tree revealed a main haplogroup M and twelve minor haplogroups, which suggested a large number of small scale in situ domestication episodes. In particular, haplogroups D1 and D6 represented two highly divergent lineages in the Tibetan highlands and Island Southeastern Asia, respectively. Network analysis of haplogroup M further revealed one main subhaplogroup M1 and two minor subhaplogroups M2 and M3. Intriguingly, M2 was mainly distributed in Southeastern Asia, suggesting for a local origin. Similar with haplogroup D6, M3 was mainly restricted in Island Southeastern Asia. This pattern suggested that Island Southeastern Asia, but not Southeastern Asia, might be the center of domestication of the so-called Pacific clade (M3 and D6 here) described in previous studies. Diversity gradient analysis of major subhaplogroup M1 suggested three local origins in Southeastern Asia, the middle and downstream regions of the Yangtze River, and the Tibetan highlands, respectively. We identified two new origin centers for domestic pigs in the Tibetan highlands and in the Island Southeastern Asian region.
