如果发现了氨基酸，并且它们普遍表现出同一种偏向性——要么像地球上的氨基酸一样是左旋的，要么是右旋的，那将会格外有趣。
Because simpler membranes are more likely to have formed from the natural organic chemistry factory on prelife Earth, the protocell project is working on plainer lipids - chiefly ordinary fatty acids.
由于在无生命的地球上，天然有机化学系统很可能形成较简单的膜，所以本次古生物工程也采用较简单的脂质——主要是普通脂肪酸。
And they found that they'd created a few amino acids. All life on Earth relies on these compounds to make proteins.
