Abstract

In the early Precambrian, microorganisms, bacteria, possibly cyanobacteria, and even unicellular eukaryotes accompanied the formation of weathering crusts, i.e., the crusts were initially formed with the participation of bacteria. Findings of fossil microorganisms in ancient weathering crusts are important because they suggest that the land was already inhabited at such a distant time. Modern bacterial-paleontological research has changed our understanding of the earliest stages of the evolution of life on Earth.

第 4 章 早期白寒武纪风化壳

摘要

在早前寒武纪，微生物、细菌，可能还有蓝细菌，甚至单细胞真核生物都伴随着风化壳的形成，即风化壳最初是在细菌的参与下形成的。在古代风化壳中发现微生物化石非常重要，因为它们表明这片土地在遥远的时代就已经有人居住了。现代细菌古生物学研究改变了我们对地球生命进化最早阶段的理解。
