Abstract

A new study of ancient mitochondrial DNA from Newfoundland and Labrador indicates that this region at the northeastern margin of North America was populated three times in succession by different indigenous groups. This research helps shed light on the movement of populations across the continent, following the initial peopling of the Americas.

摘要

一项对来自纽芬兰和拉布拉多的古代线粒体 DNA 的新研究表明，这个位于北美洲东北边缘的地区曾先后被三个不同的原住民群体所居住。这项研究有助于揭示在美洲最初有人居住之后，人口在整个大陆的迁移情况。
