daka

Late in December 1997—a boom year for hominid fossils in the Middle Awash—graduate student Henry Gilbert noticed the top of a cranium eroding out of the Daka sediments.

就在那一年的十月月底，研究生亨利·吉尔伯特野外考察时在达卡沉积层上发现了一片头盖骨，随后该研究小组在头盖骨周围出土了一块重达四五十公斤的砂岩块，并用石膏和医用绷带包住带了回来。

In the short walk from Herto to Daka, however, something tangible of our humanness had definitely been stripped away too—notably, several hundred cubic centimeters of gray matter.

虽然达卡距离赫托并不是太远，但我们人性中的某些有形部分已经随着时光的回溯而被剥去了——尤其是大脑中那几百立方厘米的灰质部分。
