By the time that the Earth was just a billion years old (3.5 billion years ago), there is indication that biological processes were already well established. Within a few hundred million years of this mark, individual cells and filaments had appeared, their fossilized remains preserved in Australia and South Africa. Two billion years ago, many examples of what are thought to be the precursors of modern cyanobacteria were present, as can be seen in microfossil-bearing rock found at locations in Canada and elsewhere. This research proposal deals with the components, design and mechanical operation of these early life forms, addressing questions such as:

当地球只有10亿岁时（35亿年前），有迹象表明生物过程已经建立起来。 在这一标志之后的数亿年内，出现了单个的细胞和细丝，它们的化石遗迹保存在澳大利亚和南非。 20亿年前，许多被认为是现代蓝藻前体的例子都存在，正如在加拿大和其他地方发现的含有微化石的岩石中所看到的那样。 这项研究计划涉及这些早期生命形式的组成部分，设计和机械操作，解决以下问题：
