But that date has been overthrown by work employing cosmogenic nuclide dating.

但该日期已被采用宇宙年的工作推翻。

To test that idea, they directly dated the cave breccias in Members 2 and 4 using cosmogenic nuclide dating, which Dr Granger helped develop.

为了验证这个想法，他们使用格兰杰博士帮助开发的宇宙年法，直接对员 2 和员 4 中的洞穴角砾岩进行了年。

A sophisticated dating technique, called cosmogenic nuclide dating, has upended previous estimates—and, with that, is rewriting an important chapter in the story of human evolution.

一种称为宇宙年的复杂年技术推翻了之前的估计，并由此改写了人类进化史的重要篇章。

When a breccia-forming object falls into a cave, it finds itself shielded from cosmic rays, and the steady decay of its existing cosmogenic nuclides can be used to determine how long ago it fell in.

当形角砾岩的物体落入洞穴时， 它发现自己免受宇宙射线的影响， 并且其现有的宇宙的稳定衰变可以用来确定它落入洞穴的时间。
