美国哥伦比亚广播公司: 有研究显示,藏族人之所以能够在世界屋脊上繁衍生息,是因为他们有着一种特殊的基因.
CBS News: A study suggests Tibetans living on the "roof of the world" can thank an extinct human relative for providing a gene that helps them adapt to the high altitude.
Past research has concluded that a particular gene helps people live in the thin air of the Tibetan plateau. Now scientists report that the Tibetan version of that gene is found in DNA from Denisovans, a poorly understood human relative more closely related to Neanderthals than modern people.
