This project aims to find out how life on Earth survived the revolutionary changes when cyanobacteria first released oxygen into the atmosphere. These events led to a transition from anoxic (oxygen-free) to oxic (oxygen-rich) conditions. A comparative genomic view across a series of photosynthetic organisms will be performed at the molecular level with ecological interpretation. Understanding of what metabolic changes occurred in response to the shifts in the environment will have wide implications for predicting the evolutionary events that are still occurring today, such as rapidly changing climatic conditions. This fundamental research will enhance Australia's profile in this field.

该项目旨在找出当蓝藻首次向大气释放氧气时，地球上的生命是如何在革命性的变化中幸存下来的。这些事件导致了从缺氧(无氧)到有氧(富氧)的转变。一系列光合作用有机体的比较基因组观将在分子水平上进行生态学解释。了解随着环境变化而发生的代谢变化将对预测今天仍在发生的进化事件具有广泛的影响，例如快速变化的气候条件。这项基础性研究将提升澳大利亚在该领域的知名度。
