prebiotic life的意思|示意

This has led many to argue that the starting point for the history of life on Earth was the denovo emergence of the RNA world from a nucleotide-rich prebiotic soup.

这使得很多人主张，地球生命历史的起点是在富含核酸的汤里反复出现的——也就是RNA世界。另外一些人非常怀疑这一观点。

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.

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。
