这个结果激起了许多年的关于生命起源以前的化学实验。
This results initiated many years of prebiotic chemistry experiments.
从另一方面看，如果这种对氨基酸的优先选择机制早在生命起源之前就已经存在，那就说明在生命出现以前，必定存在一种比生化反应还要早的化学反应过程。
On the other hand, if there is a mechanism to choose handedness before life emerges, it is one less problem prebiotic chemistry has to solve before making life.
