Based on whole mtDNA sequencing of 14 samples from Northern Island Melanesia, we characterize three formerly unresolved branches of macrohaplogroup M that we call haplogroups M27, M28, and M29. Our 1,399 mtDNA control region sequences and a literature search indicate these haplogroups have extremely limited geographical distributions. Their coding region variation suggests diversification times older than the estimated date for the initial settlement of Northern Island Melanesia. This finding indicates that they were among the earliest mtDNA variants to appear in these islands or in the ancient continent of Sahul. These haplogroups from Northern Island Melanesia extend the existing schema for macrohaplogroup M, with many independent branches distributed across Asia, East Africa, Australia, and Near Oceania.
基于对来自北岛美拉尼西亚的14个样本的完整线粒体DNA测序，我们鉴定出了宏单倍群M的三个先前未解析的分支，我们将其称为单倍群M27、M28和M29。我们的1399个线粒体DNA控制区序列以及文献检索表明，这些单倍群的地理分布极为有限。它们编码区的变异表明其分化时间早于北岛美拉尼西亚最初定居的估计日期。这一发现表明，它们是最早出现在这些岛屿或古代萨胡尔大陆的线粒体DNA变体之一。来自北岛美拉尼西亚的这些单倍群扩展了宏单倍群M的现有模式，有许多独立分支分布在亚洲、东非、澳大利亚和近大洋洲。
