中国女科学家改写了欧洲最早现代人类史(图)

2016-07-07 10:04:41   澎湃

原标题:欧洲最早的现代人类历史,被这个32岁的中国女科学家改写了

今年5月,当《自然》杂志的编辑第一次向付巧妹的邮箱发来采访邀请时,一向不热衷于媒体的付巧妹选择了冷处理。直到编辑辗转询问到了她的另一个工作邮箱,再次发来邀请。邮件里只说“想通过介绍中国几位科研人员,了解关于中国科学的一些状态”。

32岁的付巧妹在科技界可谓年轻,却已经是在古DNA研究领域具有广泛国际影响力的学者,目前是中国科学院古脊椎动物与古人类研究所古DNA实验室主任。她作为第一作者的最新研究成果“冰河时期的欧洲人群历史”,根据51个末次冰期欧亚个体的基因组数据,首次揭示了该时期欧亚地区完整的人口动态变化情况。

谜底揭晓在北京时间6月21日凌晨,《自然》杂志刊登了名为《中国科学之星》的特写报道,将付巧妹列为“十位中国科学之星”之一,称她“帮助重写了欧洲最早的现代人类的历史,并希望用古人类遗骸的DNA改写亚洲的史前史”。看到报道后,付巧妹吓了一跳,“哦,这样子。”之前她还在和朋友表示担忧“不知道报道会是什么样子”。

付巧妹入选《自然》杂志评选的“十位中国科学之星”

这不是付巧妹第一次“上榜”《自然》杂志。她所领衔的“古DNA解密现代人起源”研究曾被《自然》杂志评为“2014年度十大科学事件”之一。

古DNA研究是指通过古代生物遗体或遗迹中残存的DNA片段,探究群体遗传、人类演化等问题。它在国内还未成为“显学”,在国际上已是领域内的热门方向。

能被选入,付巧妹觉得这体现了国际上对古DNA研究的关注。在接受澎湃新闻专访时,付巧妹说,“整体而言,全世界对中国科研的结果还是比较认可的,我们还是有很大的空间的。”作为和经济不太相关的领域,付巧妹觉得,对古DNA研究的关注体现了大国的视野,值得期待。

未知

刚接触古DNA研究的人会常有盲人摸象的无助感。横亘着动辄成千上万年的时间跨度,技术也往往抵不住种种不确定性。

付巧妹记得,那根在西伯利亚的乌斯季伊希姆(Ust-Ishim)河边被一名艺术家偶然发现的腿骨,除了知道它来自4.5万年前之外,什么都未知。“我们不知道这能解决什么问题,也不知道会导向哪里。没有一个已经呈现的研究可以让你参考。”付巧妹说。
