所以研究也不仅仅因为有兴趣,研究必须要有价值,当年在美国的很多研究院所提出研究 for fun、研究 for profit,今天不是研究For fun,我们不是research for fun,也不是research for profit,而是research for solving problems with profit and fun。

(导读 阿金)千百年来,欧亚大草原一直是人口迁徙和文化交流中心。本研究为了解青铜时代大迁移之后该地区的人口历史,对137名古代人类基因组做了测序,时间跨度约4000年。发现从铁器时代起统治草原的古西提人历经民族融合,其人口组成从青铜时代晚期印欧语系的西欧牧民逐渐过渡到如今的东亚突厥语系民族。
