Scientists identify 34,000-year-old Early East Asian of mixed Eurasian descent
科家定了，混血之人後代，34千年前的早期人。
In a new study, researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and the Mongolian Academy of Sciences present an analysis of the genome of the oldest human fossil found in Mongolia to date.
在一新研究中，德克斯普朗克演化人研究所，及蒙古科院的研究人提出了一，迄今有在蒙古之最古老人化石的基因分析。
They show that the 34,000-year-old female inherited around 25 percent of her DNA from western Eurasians, demonstrating that people moved across the Eurasian continent shortly after it had first been settled by the ancestors of present-day populations.
他指出，名34千年前的女性，西方人了大25％其DNA。人，在今族群的祖先，首度定居大後不久，徙越了大。
The study also shows that this individual as well as a 40,000-year-old individual from China carried DNA from Denisovans, an extinct form of hominins that inhabited Asia before modern humans arrived.
研究也，除了自中一具4年前的之外，此也具有源自丹尼索瓦人的DNA。丹尼索瓦人是在代人到之前，存在於洲之多人族中，一已的人。

In 2006, miners discovered a hominin skullcap with peculiar morphological features in the Salkhit Valley of the Norovlin county in eastern Mongolia. It was initially referred to as Mongolanthropus and thought to be a Neandertal or even a Homo erectus. The remains of the “Salkhit” individual represent the only Pleistocene hominin fossil found in the country.
於2006年，在蒙古部，夫林的索基特山谷中，名工了一，具有特形特徵的人族骨。最初被Mongolanthropus(蒙古人)，且被是尼安德塔人，甚至是直立人。此“基特”的骨代表了，在此地被的唯一更新世人族化石。
Ancient DNA extracted from the skullcap shows that it belonged to a female modern human who lived 34,000 ago and was more related to Asians than to Europeans. Comparisons to the only other early East Asian individual genetically studied to date, a 40,000-year-old male from Tianyuan Cave outside Beijing (China), show that the two individuals are related to each other.
自此骨的古DNA示，它於一具，活在34千年前的代人女性，且洲人比洲人更有血。迄今多有之另一具早期(自中北京郊外天元洞穴，一具4年前的男性)的研究比，示彼此有血。
However, they differ insofar that a quarter of the ancestry of the Salkhit individual derived from western Eurasians, probably via admixture with ancient Siberians.
不，她不同到，索基特的血，四分之一源自西方人的程度。可能由古西伯利人的混血。
“This is direct evidence that modern human communities in East Asia were already quite cosmopolitan earlier than 34,000 years ago“, says Diyendo Massilani, lead author of the study and researcher at the Max-Planck Institute for Evolutionary Anthropology. “This rare specimen shows that migration and interactions among populations across Eurasia happened frequently already some 35,000 years ago“.
研究首要撰文人，克斯普朗克演化人研究所研究，Diyendo Massilani宣：「是於，代人群落早在34千年前，已十分布的直接。此罕的本，大35千年前，多族群之越的徙及互，已繁生。」
The researchers used a new method developed at the Max-Planck Institute for Evolutionary Anthropology to find segments of DNA from extinct hominins in the Salkhit and Tianyuan genomes. They found that the two genomes contain not only Neandertal DNA but also DNA from Denisovans, an elusive Asian relative of Neandertals.
此些研究人使用了，在克斯普朗克演化人研究所，的一新方法，在索基特山谷及天元洞穴，已之人族基因中，找DNA片段。他，基因不具有尼安德塔人的DNA，而且具有自丹尼索瓦人的DNA。丹尼索瓦人是尼安德塔人，於洲令人困惑的一同族。
“It is fascinating to see that the ancestors of the oldest humans in East Asia from whom we have been able to obtain genetic data had already mixed with Denisovans, an extinct form of hominins that has contributed ancestry to present-day populations in Asia and Oceania”, says Byambaa Gunchinsuren, a researcher at the Institute of Archaeology of the Mongolian Academy of Sciences. “This is direct evidence that Denisovans and modern humans had met and mixed more than 40,000 years ago“.
蒙古科院考古研究所研究，Byambaa Gunchinsuren宣：「咱已能得的人中，於最古老人的祖先，已丹尼索瓦人(是曾血提供，在洲及大洋洲之今族群的一已人)混血，是吸引人的。是丹尼索瓦人代人，4多年前已相逢且混血的直接明。」
“Interestingly, the Denisovan DNA fragments in these very old East Asians overlap with Denisovan DNA fragments in the genomes of present-day populations in East Asia but not with Denisovan DNA fragments in Oceanians. This supports a model of multiple independent mixture events between Denisovans and modern humans“, says Massilani.
Massilani宣：「引人好奇的是，在些古老人中，丹尼索瓦人的DNA片段，今族群基因中，丹尼索瓦人的DNA片段重，而大洋洲中，丹尼索瓦人的DNA片段有重。支持了一，在丹尼索瓦人代人，有多立混血事件的模型。」
