人类进化缺失一环 连接人类与狐猴

 "Missing Link" Found: Fossil Connects Humans, Lemurs?

灵长类动物“艾达”的化石年代可追溯到4700万年前，于5月20日被揭开神秘面纱。一些科学家表示，这是有关人类进化的一项重大发现。

艾达化石是“国家地理新闻”网站2009年点击率最高的图片。

一些专家认为，这一化石的发现只能是一个重大事件，而不是一个具有里程碑意义的事件。

The 47-million-year-old, exceptionally preserved primate fossil "Ida," unveiled on May 20, was hailed by some as a major discovery in human evolution.

The publicity frenzy made National Geographic News's brief coverage our most viewed page of the year—and inspired a backlash as some experts, including one here at Nat Geo HQ, suggested Ida was more media event than milestone.
