我们设计并进行了一系列原始汤米勒-乌里式的实验，用氢化气体和试剂来比较“氢化世界”的火花放电产物和“氢化世界”的标准反应。虽然该体系的氢气对氨基酸产物的分布影响不大，但在产物空间的其他区域可以看到显著的差异。我们不仅观察到了大约120个 新物种，而且如果将两个氢同位素世界进行比较，我们还会看到它们在分布上的显著差异。在这两个世界中都可以确定几个同位素匹配，但很大一部分产品在相应的同位素世界中没有对应的产物，在D世界约有43 新物种，在H世界约有39 新物种。这表明，在其他相同的反应条件下，同位素交换(只添加一个中子)可能会导致化学空间的显著额外复杂性。
We designed and conducted a series of primordial‐soup Miller‐Urey style experiments with deuterated gases and reagents to compare the spark‐discharge products of a “deuterated world” with the standard reaction in the “hydrogenated world”. While the deuteration of the system has little effect on the distribution of amino acid products, significant differences are seen in other regions of the product‐space. Not only do we observe about 120 new species, we also see significant differences in their distribution if the two hydrogen isotope worlds are compared. Several isotopologue matches can be identified in both, but a large proportion of products have no equivalent in the corresponding isotope world with ca. 43 new species in the D world and ca. 39 new species in the H world. This shows that isotopic exchange (the addition of only one neutron) may lead to significant additional complexity in chemical space under otherwise identical reaction conditions.
